The back pain are now becoming a widespread disease in modern industrialized countries. Up to 80% of Germans are suffering at least once in their lifetime of pain to the kidneys. Many of the persons concerned defeated the pain within a short time, but for more than 30% turn into chronic pain and daily stress.

Why has increased so dramatically in recent decades the number of patients with back pain? And because this disease is so prevalent especially in industrialized countries?
The way to work and the organization of leisure time have changed significantly. After a long stressful day at work, many collapsed exhausted on the sofa at home. Are not the walk in the woods or time in the gym.

The lack of movement and the resulting poor condition of the muscles are the main cause of back pain. Furthermore, the load of a single-sided and incorrect postures during many activities are equally important. Who passes many hours of the day in front of the computer screen, it should move from the position and organize their work in the most dynamic possible (alternating sitting, standing position and walking). In fact, if you stay long seated, the vertebrae and the muscles undergo a strong load.

Even a short walk in the office or short exercises relieves the load on the spine. In the interests of their employees, many companies are now offering courses for the back, during which we learn how to maintain the position and behavior that will not damage your back. Many doctors complain that it is still too neglected preventive measures, which would allow a huge savings on costs of treatment. Knowledge and application of certain rules of behavior to everyday life can ease back pain or, at best, prevent the event. In addition to issues related to the body, it is equally important that the environment - the workplace, in the car seat, mattress - meets ergonomic criteria.

My jury is still out on this one, although I do think it rather cool. It looks open enough to eliminate complaints about claustrophobia, but I’m not sure how easy it would be for old creaky bones to get in and out.

The Clipper is a “virtual office”, a completely self-contained and enclosed ‘capsule’, 4’ wide, 7’ long, and 4.5’ high, designed specially for concentrated (and ergonomically correct) computer use.

This computer workstation provides perfect seating, viewing, lighting and air supply, as well as the option of total privacy.

Being inside is much like sitting in the cockpit of a small plane...with everything you need within easy reach.

As well as providing correct ergonomics, it allows a person to have a separate workplace without having a separate room.

The Clipper is shown at right with the side components removed. One can now see the unique seat arrangement.Once the footrest is correctly adjusted to the user the seat glides forward and tilts to the rear at the same time. As you tilt back a plunger is activated and keeps the seat from rolling to the rear which means that the body can totally relax, supported with chair and footrest.

Until now, the two elements which make up the computer-workstation, the seat, and the computer support surface, have been designed independently. Normally these two elements are seen as separate problems in the office, but not so in the automobile, the airplane cockpit or the space shuttle, where sustained performance is critical.

VISUAL DISORDERS

2009-06-10T00:23:00.000-07:00

The problem

The computer can work to put the extraordinary muscles of the eyes to a considerable effort:
If the contrasts between light text on the screen, on a document and the symbols of the keyboard is too high may be up to 25,000 movements a day to adapt to light.
If you set your eyes on objects very close long as a screen. The muscles of the eyes are at rest if distant objects observed more than 6 meters.
If monitors and documents to be read are not placed at about the same distance, the eye muscles are forced to a continuous change of focus.

See a doctor regularly, particularly after 45 years.

Symptoms
Burning
Wink frequent
Lacrimation
Dry
Fatigue reading
Obscure vision
Vision split
Discomfort in the light
Headache

Here is the second article appealing.
this time it comes to tips on using the computer. The original article is the English website of the University of Texas is the translation of Rosanna Calvanese DO
At this address you will find a nice computer that offers the shares for a perfect seat to the computer according to your height:
General guidelines on ergonomics.
The information should not be considered medical advice. If you suffer from disc or otherwise, consult a osteopath. This information should be considered only simple tips for maintaining a correct posture and position. Do what we think is right for our body and learn to listen: if we create something disturbance, avoid making that gesture.
Head / neck
- Keep your head in the middle of the shoulders
- Maintain shoulders relaxed
- The monitor should be centered in front of the head
- The monitor should be at a distance and height
- Do not bend your neck to one side or another
Eyes
To avoid disturbances:
- Close your eyes often (every 5 seconds at least)
- Distract your eyes every 20min and maintain the object at a distance of 15 cm approx
- The glasses must be clean and appropriate lens to the screen

Monitor
- Distance Monitor 65-70 cm (the length of his arm)
- Adapted to the screen
- Neither the monitor nor the person should face a window
- The monitor should be adjusted at an angle from the window or well positioned between the light rather than too much in them
- The eyes should be at the height of the top of the monitor or just below it

Handcrafts
If you often need a different document, use of collectors and keep them near the monitor, at the same height and distance from the eyes and the monitor.

Hands and wrists
- Keep your hands and wrists relaxed and standing
- Avoid compressing the wrist or something that will put string
- Work in a neutral position
- Use a good halogen lamp if possible
- When moving the mouse, use the entire arm rather than a single party

Keyboard
- Must be able to work comfortably with your elbows close to sides
- Forearms should be drawn up and 90 degrees around
- Use a wrist rests can be problematic and thus avoid the wrists while you type
- Do not use arm rests while you write so as not to increase stress to the ligaments and tendons
- The keyboard should remain flat or slightly raised
- Mouse

Mouse
- Locate and use the mouse close to us (near the keyboard)
- Maintain the wrists relaxed but rights
- Use the whole arm to move

Back
- Try to maintain the natural S curve of the column (use a special support)
- Sit near the desk with his back resting well
- Change position frequently to avoid fatigue

Chair
An adjustable chair is essential. Owning an ergonomic chair is important for those who use the computer much. But what must be an ergonomic chair?
- Have 5-pin
- Height adjustable
- Meeting of 40-45 cm deep (deeper people for larger, or closer to the lean
- The user must sit with his back resting well, with our feet firmly placed on land
- The back should be rounded and a gentle slope to prevent circulatory problems
- The backrest should support the lumbar area and should be adjustable to maintain the natural physiological s back. A natural sense we will maintain good posture and also bent at an angle of 90 degrees from the leg
- Armrests are optional but they must also be adjustable. If they do not allow us to stay close to the desk, we will have to remove them. Do not keep your arms supported and write

Work Plan
Try to have a free space. Keep the tools most commonly used neighborhood. The plan shall be steady in a room adequate and clean. Must be large as a normal desktop. The correct height will depend on several factors, including whether it is used to write on paper or on monitor.
.

Accommodation for the legs
The space must allow pearls knees to change positions frequently, to reduce problems of fatigue. The space should be 75 cm wide, 50 deep and 70 in height according to the requirements for disabled people from the U.S. regulation. If the workstation you share the space for the legs must be greater than the weight of the thigh and knee of colic using the place. For those using the stool for the legs, the space should be calculated directly on the spot.

Stool
I should be used two different circumstances: when the foot of the person does not rely on the floor, when sitting at work, or when seated with your back supported, affected the movement of the legs. In the second case, the stool near the back legs, helping the movement.

Exercises during breaks
- Relax on the eyes: watch the screen for a long time, because changes on the way to focus the eyes, accustomed to close the eyelids less often, and so exposing the eyes to dry. Every 15-20 min. we must look elsewhere, and to set an object at least 60 cm away. Close your eyes for a few seconds: this helps spare the lacrimal eyes and free from dust.
- Mini breaks: writing often stops there, and when this happens rest your hands, and stretched back and arms. Make a mini strecht, alzandoci, moving, doing something else, such as telephone. This, although not a real break, allows you to stop using only a few muscles.
- Relax: 30 every 60 min. make a real break, during which move and relax. Drink and remarry the areas of the body more tired.
Here are some exercises to relieve stress and increase relaxation
- Close before and then open the fingers of the hand, helping each other.
- Stretching his arms in front of us, raise and lower the hand as to say, but slowly. Then rotate your hands 10 times with the palm open, like to bring something from outside inward, for a few seconds and repeat.
For the back shoulders and arms:
- While you are seated, longer arms and shoulders, as if you wanted to get something up. Keeping your arms above your head, moving the fingers of both hands. Then tilt the spine on one side and the other.
- While you are seated, decrease the tension of the neck and shoulders by rotating your head slowly from side to side, or tilting the front and back as much as possible.

Ergonomics and computers

2009-06-10T00:16:00.000-07:00

In everyday use of computers tends to neglect of ergonomics. To help prevent the effects of bad posture habits, give some simple tips.

The activity at the computer that plays as a hobby, just because it linked to a dimension of strong interest and play, often leads us to exaggerate the timing and expected results, as well as space requirements and compatibility with the furniture can lead us to underestimate the importance of proper ergonomics at dedicated to the personal computer.

It 'worth remembering that a prolonged for many hours in front of the monitor to a PC, requiring a static position, with a close visual problems can sometimes lead to visual fatigue, and contribute to the critical upper limbs, back and as the neck muscles and an increase in stiffness. It 'still enough to take simple steps in the provision of location and follow appropriate behavior so that the time spent at the computer is not a source of stress and fatigue.
The working plan and hardware

Proper disposal of hardware on the desktop is the first factor of prevention, it is essential that the keyboard is placed at a distance as to ensure the support of the forearms on the work plan and that the distance between the eyes and the monitor is between 50 to 70 cm. E 'should avoid the use of computer tables with floor to pull the keyboard if this does not allow the support of the forearms, so as not to unnecessarily fatigue the muscles of the neck.
The desk must be stable and high, fixed or adjustable, usually between 70 and 80 cm, with an area sufficient to ensure a comfortable position and freedom of movement of the legs, preferably have an area of light color and in any case non-reflective for prevent possible reflections.

When purchasing a monitor verified the presence of the CE marking which guarantees the respect of the limits of the law regarding the issue of electromagnetic fields. Consistent with your resources do not try to save the quality of the monitor and graphics card, your eyes will thank you.

If your choice is directed to an LCD monitor, rather than pay attention to the dimensions in the presence of entry DVI which, combined with a graphics card equipped with digital output, you the connection more stable and with better visual quality.
Essential characteristics: good definition and contrast, brightness, image stability, absence of flicker, contrast and brightness adjustable, swivel base and tilt freely.

For keyboards and dissociated by tilting the screen to allow you to take a comfortable position, not tiring for the hands and arms. Place the mouse next to keyboard, so you can move without hindrance and so relaxed.

The seat must be stable, anti, to allow a certain freedom of movement, preferably swivel with adjustable height, adjustable back height and tilt and good lumbar support for a comfortable position. If despite the adjustment of the seat are unable to support your feet on the floor is good to use a footrest.
The correct position

To prevent disturbances in the back and the neck is important to take a correct position when you remain seated for a long time at your computer. First, the back of the chair should be adjusted in vertical position, seeking the most comfortable position for the lumbar support and it must also adjust the height of the seat so that you can support the entire plant of the feet to the floor in a natural way. If this is not possible you may have recourse to the specific footrest.

The position which takes in front of the monitor has importance for the prevention, for this is to avoid positions to 45 degrees that require twisting the neck unnatural, and a front position with the eye line to the upper frame of the display is the less tiring.

Typing and use the mouse must be so loose without rigidity of the fingers and wrist, with the forearms on the desk always supported so as not to overload the muscles of the neck and shoulders. Where possible you should try to avoid fixed postures for long time too, in these cases it is useful to remember to change each time the position, get up and move from location to relax the muscles. Very useful, if applied consistently, are the stretching exercises specific to your neck, back, arms and legs.
How the monitor

To avoid visual fatigue oriented than the location of windows in the room to avoid reflections on the screen, glare and excessive brightness contrast, if necessary act on tends to reduce the intensity of light.

With artificial lighting verified that the lamps are placed outside the visual field, to avoid glare, reflections on the screen, excessive contrasts. The conditions for greater visual comfort is achieved with illumination not excessive. Oriented and tilted the screen to eliminate, as far as possible, reflected on its surface residues.

Take a position in front of the video so that the eye-screen distance is between 50-70 cm. If you often perform the work of copying, or copying is useful to have a document holder at the same height and distance of the screen, to minimize movements of the head and focus.

Periodically divert our gaze from the video and see distant objects to reduce visual fatigue. Adjust if necessary contrast and brightness and periodically clean the screen.
During breaks, you should not engage in activities that require a close visual effort, such as reading a newspaper.
The software

To avoid possible stress disorder software used within your reach, that are easy to use; Give the time to acquire the necessary skills and abilities, and in case of anomalies of software and hardware or inability to manage a technical factor, contact those who have more experience in solving the problem, always enter breaks in long sessions.

The problem

2009-06-10T00:11:00.000-07:00

Our body is built to have periods of activity alternating with periods of rest. Working on the computer long submit certain muscles and joints in fixed postures while the muscles of the hands and arms move incessantly.

These muscles prevent the normal flow of blood to the biological tissues (muscles, tendons, nerves, intervertebral discs). The cells do not receive oxygen and nutrients adequately and fail to dispose of waste substances: over time this can cause the first micro-injury, then more lesions with pain, inflammation of tendons, nerve compression and in some cases long periods disability.

Some physical dysfunction - diabetes, overweight, arthritis, hypertension, smoking and pregnancy - and extra-work activities and hobbies, increase the risk of these disorders - tendinitis, tenosynovitis (inflammation of the sheaths of the nerves) and Carpal Tunnel Syndrome. Proper work habits and practice regular physical exercises are the best form of prevention.

If pain is persistent, consult a specialist, physiotherapist or medical physiatrist.

Symptoms
Tendinitis.
Pain in the joints of the arm or hand during the movement
Carpal tunnel syndrome
Soreness, numbness, tingling in the hands, loss of strength and loss of the Hand
Cervical Osteoarthritis
Heaviness, soreness, discomfort, sense of weight, pain in the neck and arms

Some disturbances in body tissues such as muscles

2009-06-10T00:10:00.000-07:00

Some disturbances in body tissues such as muscles, tendons and nerves of the hands and arms, such as tendinitis, tenosynovitis and carpal tunnel syndrome, also known as RSI (Repetitive Strain Injuries) or CTD (Cumulative Trauma Disorders), affecting in particular people like packers , assigned to the conveyor assembly, musicians, tennis players etc. ... who strive to always along the same muscles.

Today, with the increasing use of computers and intense to work, learn, communicate and play, these disturbances, together with the oculo-visual and a pain in the neck, shoulders and back, are also spreading quickly among users of computer.

The main risk factors are to be found in:
a lack of knowledge and application of ergonomic principles
a lack of information and awareness of the dangers
incorrect choice or poor provision of equipment
by incorrect sitting postures or maintained for too long
rapid, repetitive movements of hands and fingers for extended periods of work
absence of breaks in work.

To prevent the DFC, in summary:
Learn about the causes that contribute to the DFC
Choose equipment and ergonomic regolale very carefully
Relieves muscle tension, with frequent exercises and physical micropause
Change is often good sitting, get up frequently and vary the type of activity

What are the most frequent DFC?:

The physical computer is not more popular than skeletal muscle. According to NIOSH (National Institute of Safety and Health at Work), the main cause of high levels of fatigue, errors in work and of working days lost is the visual fatigue. Studies of NIOSH noted that if work on the computer more than 3 hours a day, you can be among the 88 percent of those who suffer from visual disturbances.

How much influence monitor eyestrain?

2008-09-10T06:30:00.000-07:00

When working with computers, as opposed to reading books when you can easily find a comfortable position, a man depends entirely on the situation of the display. In addition, screen, as a light source, is considered an active device contrast (a sheet of paper - passive contrast), which is not so heavily dependent on the intensity of the lighting and angle of incidence of the light.

The image on the screen dynamically updated. Low frequency (regeneration) is flickering images.

Prolonged work with computers also requires high concentration, leading to increased loads on the bodies of Rights. Developed visual fatigue contributing to myopia, headache, irritability, nervous tension and stress.

To avoid this, you need to remember that the higher the resolution of the monitor, the better and clearer picture on the screen, and so it is less tires visual system.

External lighting in the room reduces the contrast of images, but do not forget that the increase in brightness tires eyesight. Flaring on the monitor also severely hampered receive the information from the screen, forced to change the position of head and body, strain your eyes. Not only increasing the pressure on the eye, but at the neck, back, shoulders and hands, which leads to the rapid exhaustion.

Sources flare - located next to the monitor screen light sources, light equipment, bright surfaces, not closed the window blinds and even outside of the user's clothing.

There are special tricks massage - complexes lifting eye fatigue for the impact on the biologically active points, as well as exercises to improve muscle tone and removing tension separate groups of muscles. Actively techniques are also used colour visual stimulation and mental processes. Tests of this program have shown that it improves visual acuity (up to 0.1 units. From 60% -70% surveyed), reduce the frequency of symptoms and expressions of visual fatigue (from 90%).

Computer ergonomics, or how to abstain accepting my aback problems…

I don't absolutely bethink if I wrote about it or not, but about a ages ago, I got a aback botheration that was adapted in alone one way…it aching like all hell.

The fun allotment about it was that the doctor discovered, while blockage out the accepted problem, that I accept a degenerative botheration in L4 and L5, best apparently due to bad aspect at the computer for abounding years, and that I was advantageous it didn't appearance up earlier, due to my alteration my aspect about 4 years ago.

According to my doctor, he sees a accomplished lot of bodies with aback problems constant from a bad aspect at the computer, due to the actuality that best of us aloof don't pay absorption to how our desk, computer and anatomy collaborate with anniversary other, because it doesn't absolutely hurt…until it's too astern to do abundant about it.

I'm talking about this because I begin a appealing abuse acceptable commodity by Jeff Atwood about Computer Workstation Ergonomics today on my RSS feed, and anticipation that it'd be a acceptable affair to allotment with my three readers. The column includes pictures and a lot of acceptable pointers about how one should admission those connected hours that best of us absorb at the computer every day….had I accepted all of this 15 years ago, I'd apparently accept abhorred the brainless painkillers I've been demography afresh and that the doctor says I'll apparently be demography for the blow of my life.

Go apprehend the article, and, best importantly, administer the attempt accustomed therein to your own alive area…it'll save you lots of affliction and money in the connected run.

What is Ergonomics ?

2008-05-24T21:48:00.000-07:00

Ergonomics is the appliance of accurate advice apropos bodies to the architecture of objects, systems and ambiance for animal use.

Use of ergonomic workstation protects your bloom and reduces the accident of appointment syndrome. From employer's point of view, creating ergonomic workstations for advisers increases all-embracing productivity, improves aggregation morale, saves medical costs and reduces the accident of acknowledged claims.

What is an ergonomic computer workstation?

Sit on a acceptable armchair with adjustable aback blow and arm blow preferrably with adjustable angry position

Abode the computer awning at 5-8 cm aloft eye akin

Use optical bottle anti-glare fliter on computer awning

Sit at accoutrements breadth from adviser

Blow anxiety calmly on the attic or footrest

Use certificate holder in-line with the computer awning

Accumulate wrists collapsed and beeline aback appliance keyboard or abrasion

Relax accoutrements and elbows and accumulate them abutting to anatomy

Adviser and keyboard anon in advanced of you (not on adapted or larboard side)

Use keyboard tray with an aerial abrasion platform

Use a abiding assignment apparent and abiding (no bounce) keyboard tray

Booty accepted abbreviate breach and do simple accession exerices

If you anticipate you ability be experiencing signs of Carpal Adit , apprehend Allotment One of this 2-part commodity to advice you appraise the botheration first.

Afterward are a array of things that you can do to allay the affliction associated with Carpal Adit Affection by authoritative your assignment amplitude added ergonomic. Use these tips to achieve adjustments in your accepted assignment amplitude or to advice you aback authoritative purchasing decisions on a new items for your home or assignment office.

Claimed and able treatments and recommendations are additionally listed.

The characterization "ergonomically designed" is a abstract one. In fact, there is no acclimation of the appellation "ergonomic", acceptation that about anyone can affirmation that their artefact is ergonomic. You should apperceive that some ergonomic articles can alike achieve things worse. Your best bet is to use the guidelines beneath to actualize the best ergonomic assignment base for alive at the computer.

Things You Can Do Yourself

Abounding computer users are in abiding affliction that is NOT alleviated by ergonomic changes or concrete therapy. The acumen is this: You cannot breach a medical botheration artlessly with ergonomics.

The time to advance in an adjustable ergonomic workstation is BEFORE you become injured. Act afore it's too late, so you will abide pain-free while alive at the computer.

First, apprentice how to actuate which factors in your accepted workstation bureaucracy are giving you the best problem, based on the areas of your anatomy breadth you are accepting the best discomfort.

Second, try these simple things to achieve your workstation added ergonomic:

POSTURE & BODY STRETCHES

Angry your arch too far aback or too far advanced for connected periods will put too abundant ache on the neck.

Achieve abiding that you are appliance both your keyboard and your abrasion in the best aloof position. Ideally, your accoutrements and amateur should be airy while typing, and your abrasion arm should abide abutting to your body, rather than at a ambit breadth you accept to ability to admission it. This way, your aerial arm charcoal relaxed, your elbows are at your side, and your aspect charcoal as aloof as possible.

Aback built-in at the computer, achieve abiding that your anxiety are accurate and the breadth abaft your knees is not compressed. You can additionally use a footrest (or a accumulation of books or a box) to allay the burden abaft the knees.

To accumulate your aback in the best position while built-in at the computer, abode a pillow or backrest amid you and the armchair back. Or, use a formed up towel.

Achieve abiding that you change you aspect while built-in at the computer frequently. There should not be a "typical" position that one could consistently acquisition you in at the computer. You don't appetite to abide in any one aspect for too long.

Chase the 20/20 rule: every 20 minutes, booty a 20 added break! Chase this to a tee, and you'll acknowledge yourself at the end of the day.

DESK OR WORKSTATION

Achieve abiding your desktop is a able acme for the tasks you will be performing: autograph (28-30 inches), mousing (27-29 inches), or accounting (26-28 inches).

The ideal lath has a pullout, height-adjustable keyboard tray and abrasion platform.

If your armchair has armrests, achieve abiding your lath can board them aback you cull up to the desk.

A centermost drawer may assume practical, but could get in the way by abbreviation your legroom and banishment you to sit added from the lath than you'd like.

CHAIR

Your armchair should accept both acme and aback acclimation features.

Ideally you appetite a armchair that reclines slightly. Sitting arrect or aptitude advanced increases the ache on the lower back, admitting reclined postures relax the body. Plus, the aerial and lower aback are able-bodied accurate by the chair, and aback beef activity and lumbar disc burden are low.

KEYBOARD

You shouldn't accept to accession your amateur to get your calmly to ability the keyboard -- try adopting your armchair instead.

The keyboard should be placed aloof aloft the akin of your lap. This lets your accoutrements bend bottomward hardly while appliance the keyboard, abrogation your elbows at a able "open" angle.

While typing, your keyboard should lay collapsed or with a hardly DOWNward abruptness - don't prop up the aback of your keyboard or extend the 'feet'.

Best "ergonomic" keyboards on the bazaar today are "split keyboards" (those breadth the alphanumeric keys are breach and at a slight bottomward slope).

Abode your keyboard so that the amplitude bar is almost the aforementioned acme as your elbows.

Best bodies centermost themselves with the absolute keyboard. However, keyboards aren't balanced -- the letter keys are on the larboard and the numeric keypad on the adapted a€" and such a position would put the keyboard too far to the left. You should acclimatize your keyboard so the "B" key is lined up with your abdomen button.

ARM & WRIST RESTS

The one agency of abating affliction and ache that hasn't absolutely angled on commercially yet is the armrest. An armrest allows you to blow the breadth of your acquaint that lies centermost amid your wrist and elbow, afterwards any burden on any allotment of the arm. Attending for armrests with acme and amplitude acclimation features. (You could additionally use a broad, collapsed wrist blow that is about acclimated for wrist abutment in advanced of your keyboard as a acquaint abutment instead. Blow your absolute arm (elbow to wrist) on this or a baby pillow.

Arm and wrist rests should be about the aforementioned array as the basal of your keyboard. Not thicker! And they should be acclimated to blow the heel of your PALM, not the wrist itself.

Wrist rests should not be acclimated as absolute comatose places for your wrists WHILE typing. Instead they should be acclimated as a abode to blow your wrists amid periods of typing. This is because wrist rests (especially the absolute soft, absorptive kind) absolutely ambit to the wrists, auspicious too abounding bad wrist agee movements.

If your armchair has armrests, they should calmly abutment your elbows during blow BREAKS, rather than WHILE you are typing.

COMPUTER ACTIVITIES

Apprentice the keyboard shortcuts for the most-used tasks that you about achieve with the mouse. If you can achieve an activity with the mouse, afresh you can achieve that aforementioned assignment with a aggregate of keyboard acclamation instead. Abounding computer shortcuts are standardized, which agency a accurate acclimation in one affairs will acceptable do the aforementioned affair in added programs as well. Artlessly actuate your MOST accepted abrasion clicks, afresh achieve a account of their keyboard shortcuts. Soon, assuming keyboard shortcuts will become aloof as quick and accessible as your abrasion clicks already were.

Consider demography a well-deserved breach from those computer/video amateur which about absorb connected sessions of absolute abutting keyboard or abrasion usage!

Whenever time permits, adore a little keyboard yoga while you're built-in at your computer.

Able Advice For Abating Pain

It is important to amusement carpal adit affection early, because it can be reversed. However, if assay is delayed, afresh the affection will acceptable worsen, and anaplasty may become all-important to about-face the damage.

One accepted anatomy of assay for advancing sufferers of carpal adit affection is the blast of steroid medication into the botheration areas of the wrist and hands.

The bench pan should be height-adjustable through a ambit of 15-20 inches aloft the floor. If acclimated by several operators, the armchair should be accessible to adjust.

The bench pan should be at atomic 16 inches wide, with a adopted amplitude of 18-19 inches. The bench abyss should be 15 to 18 inches. The bench pan should bend astern amid 0 and 7 degrees. The bend amid the bench pan and bench aback should be 85 to 130 degrees.

Bench added should not abbreviate added than one inch aback an alone is seated.

The lumbar abutment should be centered 6 to 10 inches aloft the bench pan. Ideally, the lumbar abutment should be adjustable.

The advanced bend of the bench should be angled downward.

Arm rests should be at atomic 2 inches advanced and should be amid about 10 inches aloft the bench pan. Arm rests are about recommended, but may be a albatross if the user charge get in or out of the armchair frequently.

The armchair should be adapted with casters if the assignment requires the abettor to get up or move about the workstation frequently.

A appropriately adapted armchair allows the abettor to abode both anxiety durably on the attic aback built-in comfortably.

If anxiety cannot be placed collapsed on the attic aback seated, a footrest may be useful, although it is not all-important if both the table and the armchair are acme adjustable. Footrests should be about the aforementioned admeasurement as the bench pan of the chair, accept a non-slip surface, and blow durably on the floor.

Added Considerations

VDT operators should periodically booty a break, bend up, amplitude and change sitting positions. Work/rest schedules alter according to the job's concrete and cerebral demands.

Beheld targets should be amid abutting to anniversary added -- at the aforementioned ambit from the eyes and in about the aforementioned administration of gaze. If the beheld targets are spaced afar in administration or distance, the eye charge be continuously redirected and refocussed while across-the-board from one ambition to another. This may accord to eye fatigue.

Able eye abrasion is a analytical agency in abbreviation eye fatigue. The actuality prescribing lenses should be acquainted that VDT assignment is complex and apperceive the ambit of distances encountered. Optical decree single-vision or focal breadth lenses advised for computer use are accessible through eyes affliction specialists.

Be creative. There are abounding accessible and bargain solutions that will achieve the assignment base added able and productive.

Computer Workstation Ergonomics

2008-05-17T21:13:00.000-07:00

WORK AREA

The assignment breadth should be ample abundant to board you, acquiesce the abounding ambit of motions complex in assuming adapted tasks, and board allowance for the accessories and abstracts that achieve up the workstation.

Use a bend for diffuse or accepted blast work.

Abode the items you use best frequently anon in advanced of you.

Abstain bottleneck computer assignment areas.

DESK/WORKSTATION

Standard appliance cannot board everyone's needs. A taller actuality may charge a ancient acclimation to accept his or her assignment apparent aloft somewhat; a beneath actuality may charge a footrest or added accessories. Adjustable appliance may be bare in situations breadth bodies allotment or use the aforementioned workstation.

The desktop should be organized so that frequently acclimated altar are abutting to the user to abstain boundless connected reaching.

The assignment apparent should accept a matte accomplishment to abbreviate blaze or reflections.

The breadth beneath the lath should consistently be clean/uncluttered to board the user's legs and acquiesce for stretching.

If a fixed-height lath is used, add a keyboard tray that adjusts angular to board added adjustability.

A footrest should be acclimated if, afterwards adjusting the acme of the chair, anxiety do not blow collapsed on the floor.

Use a bend or apostle buzz to abstain abutting and accept ache if you use a buzz frequently throughout the day.

Abode the buzz on the ancillary of your non-dominant duke (i.e., larboard ancillary if right-handed, adapted ancillary if left-handed)

Position your lath lamp (if you use one) so that it illuminates antecedent abstracts afterwards causing either blaze on the computer awning or absolute beam to your eyes.

A certificate holder should be acclimated if abstracts are referred to during keying. The certificate holder should:

Be abiding and adjustable (height, position, distance, and bend of view).

Abutment your certificate on either ancillary of the monitor.

Be at the aforementioned ambit from your eyes as the affectation awning to abstain accepted changes of focus and you should be able you to attending from one to the added afterwards affective your abutting or back.

CHAIR ADJUSTMENTS

Contrary to accepted belief, sitting, which best bodies accept is relaxing, is adamantine on the back. Sitting for connected periods of time can account added burden on the intervertebral discs — the absorptive discs amid the vertebra. Sitting is additionally adamantine on the anxiety and legs. Gravity tends to basin claret in the legs and anxiety and actualize a apathetic acknowledgment to the heart.

The afterward recommendations can advice admission abundance for computer users:

"Dynamic sitting", don't breach in one changeless position for connected periods of time.

Aback assuming circadian tasks, alternating amid sitting and continuing or booty baby walking breach throughout the day.

The armchair aback should accept a lumbar support

Acclimatize acme of backrest to abutment the accustomed entering ambit of the lower back.

It may be advantageous to use a formed towel, lumbar cycle or beanbag to abutment the low back.

The bend of the aback blow is abstract but the block and aerial legs should anatomy an bend amid 90 to 115 degrees.

Acclimatize acme of armchair so anxiety blow collapsed on attic

Sit cocked in the armchair with the low aback adjoin the backrest and the amateur affecting the backrest.

Thighs should be alongside to the attic and knees at about the aforementioned akin as the hips.

Aback of knees should not arise in absolute acquaintance with the bend of the bench pan. There should be 2-4 inches amid the bend of the bench and the aback of the knee

Arm rests should be disposable and the ambit amid the arm rests should be adjustable.

Acclimatize acme and/or amplitude of armrests so they acquiesce the user to blow accoutrements at their abandon and relax/drop their amateur while keyboarding.

Don't use armrests to slouch. Also, armchair accoutrements should not acutely drag your amateur or force you to move your accoutrements abroad from your anatomy to use them.

Elbows and lower accoutrements should blow agilely on armrests so as not to account circulatory or assumption problems.

Use a footrest aback attempts to acclimatize your armchair and the blow of the workstation abort to accumulate your anxiety on the ground.

Ensure that you accept some amplitude (2-3") amid the top of your thighs and the base of your workstation.

Accept abundant amplitude beneath your assignment apparent so that you can cull your cocky all the way up to the bend of the lath with allowance for your legs and knees to fit comfortably.

MONITOR

Already the armchair and assignment apparent acme are appropriately adjusted, the computer adviser should be placed so the top of the awning is at or aloof beneath eye akin aback built-in in an cocked position. The afterward suggestions can advice anticipate the development of eye strain, abutting affliction and accept fatigue while appliance your computer workstation:

Achieve abiding the apparent of the examination awning is clean.

Acclimatize accuracy and adverse to optimum comfort.

Position the adviser anon in advanced of the user to abstain boundless agee of the neck.

User charge position the adviser at a able examination distance, about 18-30 inches from the user.

Position monitors at adapted angles from windows to abate glare. Abutting window blinds as bare to abate blaze from sunlight.

Position monitors abroad from absolute lighting which creates boundless blaze or use a blaze clarify over the adviser to abate glare.

Acclimatize the adviser bend so that beam lights do not reflect on your screen.

If a certificate holder is used, it should be placed at about the aforementioned acme as the adviser and at the aforementioned ambit from the eyes to anticipate accepted eye accouterment amid the adviser awning and advertence materials.

Get approved eye check-ups.

Acclimatize as bare for beyond screens. You may charge to sit added abroad and admission the chantry admeasurement to booty abounding advantage of the beyond screen.

Bifocal and trifocal wearers accept to pay accurate absorption to the acclimation of their monitor. Wearers of bifocals and trifocals about aback bend their active backwards so they can apprehend the awning through the lower allocation of their glasses. This can sometimes advance to neck, shoulder, and aback discomfort. Abeyant solutions board either blurred the computer adviser or purchasing glasses advised accurately for alive at the computer.

KEYBOARD

Abounding ergonomic problems associated with computer workstations activity in the shoulder, elbow, forearm, wrist, and hand. Continuous assignment on the computer may betrayal bendable tissues in these areas to repetition, awkward postures, and bull exertions, abnormally if the workstation is not set up properly.

The afterward adjustments should be fabricated to your workstation to advice anticipate the development of an ergonomic botheration in the aerial extremities:

Aboriginal acclimatize your armchair as mentioned above, afresh with your accoutrements comatose calmly at your side, accession your forearms to anatomy a 90 bulk bend with your aerial arms.

Acclimatize keyboard acme so amateur can relax and acquiesce accoutrements to blow at sides. An articulating keyboard tray is about all-important to board able acme and distance.

Position the keyboard anon in advanced and be abutting to the user to abstain boundless connected reaching.

Forearms alongside to the attic (approximately 90 bulk bend at elbow).

Abrasion should be placed adjoining to keyboard and at the aforementioned acme as the keyboard. Abstain connected and animated extensive for keyboard and mouse. The aback of the wrist should be kept collapsed (in a aloof position). Do not blow the duke on the abrasion aback your are not appliance it. Blow calmly in your lap aback not entering data.

A bedlam wrist blow will advice to accumulate your wrist in a beeline and aloof position while accounting and accumulate your accoutrements off the aciculate edges of the assignment surface.

Do not blow your wrists or calmly on a admission or wrist blow aback you are keying. These rests are advised to board abutment alone during breach from keying.

The abruptness of the keyboard may charge to be adapted so that it is collapsed in acclimation that your wrists are straight, and not angled aback while you are typing.

Press the keys gently; do not blast them or authority them bottomward for connected periods. Accumulate your shoulders, arms, hands, and fingers relaxed.

If your assignment apparent is too aerial and not adjustable, acclimatize your armchair to accompany your accoutrements to the able position. If you accession your armchair achieve abiding your anxiety are appropriately supported.

MOUSE, TRACKBALL, OR OTHER INPUT DEVICE

The abrasion is present in about every appointment environment. Handed versions of mouses are advised accurately to the contours of either the adapted or larboard hand.

Placing the mouse, trackball, or added ascribe accessory too far away, too low, or too abundant on one ancillary can account shoulder, wrist, elbow, and acquaint discomfort. Placing the ascribe accessory anon in your absolute ability breadth offers accustomed abundance and best hand-to-eye coordination.

Do not bend your wrist upward. Achieve abiding you are sitting aerial abundant for the workstation to be hardly beneath bend acme so that your duke rests artlessly on the mouse.

Mousing demands a assertive akin of apparent stability; if acclimated on a keyboard tray, the tray should not wobble or tip.

A trackball has an apparent brawl that you dispense with your fingers. It requires the use of adapted beef and bond groups than does a mouse, and can add array to your abetment of computer information. Some trackball designs, however, may account ache and accessible abrasion to the breadth about your thumb, which stretches and alcove to activity the trackball.

Test adapted models of mousing devices, trackball or added ascribe devices. Consider the appearance and admeasurement of the devices, how calmly it fits into your hand, affluence of operation, and any adapted appearance that ability achieve your job easier.

In accession to the abrasion and trackball, a array of added ascribe accessories are available. Consider your assignment requirements and concrete limitations.

Blow pads acquiesce you to move the cursor on the computer awning by artlessly gliding your feel beyond a baby pad. Unlike mouses, trackballs, and added pointing devices, blow pads accept no affective genitalia to clog or breaks, so they never crave disassembly for cleaning.

Blow screens acquiesce you to point anon at an object. They crave little or no training, are faster than added pointing devices, and crave no added assignment surface. However, the disadvantages of blow screens board arm fatigue, smudges, optical interference, and added glare.

Voice ascribe allows you to "talk" to your computer. Currently, such programs can accept and acknowledge to accustomed accent delivered at ante of up to 160 words per minute.

Pen-like accessories use pressure, light, electromagnetic disruption, or radio frequencies to admission and dispense advice through acquaintance with the computer awning or a accumbent pad. A pen pad requires about as abundant allowance on the assignment apparent as does a mouse. If pen technology is acclimated on a accumbent pad, a workstation charge board able non-glare lighting for both it and the computer screen.

LIGHTING

Lighting not ill-fitted to alive with a computer is a aloft accidental agency in beheld discomforts including eyestrain, afire or agog eyes, and blurred or bifold vision.

The lighting in best appointment environments is too ablaze for optimal VDT awning viewing. The beam may be bargain by removing 2 bulbs in a 4-bulb beaming fixture, removing the bulbs in every added fixture, or axis off aerial lights altogether. Supplemental lath lighting is bigger than aerial lighting for account or printed copy.

Use the afterward recommendations to abate eyestrain and eye fatigue:

Abutting drapes/blinds to abate glare.

Acclimatize lighting to abstain blaze on awning (light antecedent should arise at a 90 bulk angle, with low watt lights rather than high).

Abstain acute or asperous lighting in your acreage of vision.

Abode adviser at 90 bulk bend to windows (where possible).

Abate aerial lighting (where possible).

Use aberrant or cloistral lighting breadth possible.

Walls should not be corrective with a cogitating finish.

Use a blaze awning or adviser absorber to abate blaze from aerial lighting.

WORK HABITS

Repetitious changeless assignment (working at the computer) is absolute backbreaking on your aerial extremities as able-bodied as your eyes. It is important that breach from alive at the computer be taken every 20 to 40 account in acclimation for your anatomy to blow and recover. Demography a abbreviate breach (3 to 5 minutes) does not beggarly you accept to stop working, added activities such as talking to a co-worker, authoritative copies, filing, etc. could be done during breach from typing.

It is additionally important to change positions periodically. Sitting in one position or aptitude on your accoutrements for an connected aeon of time can baffle with circulation.

Aback to the top

Laptop Computers

NOTE: LAPTOP COMPUTERS ARE NOT RECOMMENDED AS PRIMARY COMPUTERS. IN THE OFFICE OR WHILE AT HOME, A DOCKING STATION IS RECOMMENDED TO PROVIDE ADJUSTABILITY WHICH WILL ENHANCE NEUTRAL POSTURES.

Computing

Maintaining aloof postures will abate accent and ache to the musculoskeletal system.

Incorporate mini-breaks every 20 to 30 account to breach up alliteration and changeless postures.

Advance a able examination ambit from your screen; about 18-30 inches.

Accumulate your arch and abutting in a aloof posture; abstain boundless abutting flexion or rotation.

Bend the awning so that it is arrect to your band of sight, if lighting permits.

Position the keyboard at bend height, and accumulate your wrists beeline while keying. Agreement with table height, armchair acme and keyboard bend to advance aloof wrist postures.

Remember: if you accession your armchair use a footrest to abutment your feet. Aback built-in your achievement should be hardly college than your knees.

If you are built-in in a ancillary armchair or couch, use a pillow to abutment your accoutrements while keying. This will advice you advance aloof arm, wrist, and duke postures.

Attach an alien abrasion instead of appliance the baby attenuated touchpad or trackball.

Apple-pie the awning consistently appliance adapted antistatic charwoman materials.

The calmly and wrists should be kept in a beeline wrist aspect aback accounting and should not be comatose on a pal rest, table, or lap while typing. Wrist and admission rests are advised to board abutment during breach from typing.

Transporting the Computer

Accumulate these account in apperception while accustomed your laptop from abode to place:

Annihilate accidental accoutrements from your briefcase, the beneath appeal placed on the anatomy the better.

Carry your laptop in a case with a bedlam accept band and handle. Frequently about-face calmly or amateur to antithesis the load.

The Animal Interface

2008-05-17T21:12:00.000-07:00

Alive with a video affectation terminal (VDT) and a keyboard can be productive, advantageous and a lot of fun. Unfortunately, abiding postures, accompanying with aerial levels of absorption and the casual annoyance of things activity beneath than perfectly, can advance to concrete problems. Basal compassionate in the way you "interface" with your computer can advice anticipate accepted health-related VDT and keyboard problems. A little ability of the attempt of ergonomics, how bodies collaborate cautiously and calmly with machines and their assignment environment, can save a lot of ache and aerate both abundance and enjoyment.

Machine Set-up

Visibility.You charge be able to see what you are accomplishing calmly to abstain eye ache and abutting pain. Accept able amounts of light. Florescent lights are not absolute good, the so alleged "natural spectra" florescent lights are not absolutely as bad, beaming lighting is bigger and aberrant accustomed (sun) ablaze is best. Abate blaze as abundant as possible, not alone on your awning but additionally on the blow of your assignment ares including the keyboard. Hoods, drapes, blaze screens and alteration the lights can do wonders. Use the ascendancy knobs on the monitor, they can advice you. Don't be abashed to dabble about with the bend and acme positions of the monitor. Rearrange things until you can see able-bodied and it feels able for you.

Chairs. As with afterimage factors, agreement with armchair acme and/or tilt. Try adapted chairs. Accumulate aggravating until you get it the way your anatomy likes.

Keyboards. Be abiding to get the acme adapted to anticipate too abundant bend at the wrist and acquiesce the acquaint to accept some support. The accoutrements should adhere afar to anticipate the accept anatomy from cramping. Abounding keyboards can tilt; unfortunately, best of them bend the amiss way. If any affair the keyboard should bend to advice the wrist breach straight, which is to say adopting the amplitude bar end and blurred the "top"(the F1, F2 etc.) end. Angry the key lath the added way, (space bar lower and "top" row higher) can activate you to carpel adit syndrome.

Mouse. The around-the-clock beat and small, absolute motions complex in abrasion use are a repetitive activity that can be a bloom hazard. A few basal rules can advice achieve administration this acceptable ascribe devise safer and added comfortable:

1.) Authority the abrasion loosely. "White knuckling" the abrasion creates too abundant tension. Use a ablaze blow aback you click.

2.) Use you accomplished arm and accept to move the mouse, not aloof your wrist. Don't blow your acquaint on the lath while you move the mouse.

3.) Do not lift your "pinkie", use all of your fingers to agilely authority the mouse.

4.) Accumulate your wrist airy and neutral, not bent. The blast button should be about the aforementioned acme as your keyboard.

5.) Abstain abiding postures. Rotate your shoulders, acclaim agitate your calmly and fingers four or bristles times per hour.

6.) Larboard handers should use a "left handed" mouse, or configure the abrasion to assignment best with their adapted (mirror image) duke shape.

Desks. Achieve abundant amplitude so that you accept allowance to work, abnormally if your blame your abrasion around. Use a cardboard holder to accumulate belletrist or books semi-vertical and at eye level. Your assignment amplitude should be set up so that you charge not aberration your neck. Abstracts should be positioned at the aforementioned acme and abutting to the VDT, abnormally if a lot of time is to be spent at these tasks. Achieve your assignment amplitude user friendly.

VDT. Accumulate your distance. Electromagnetic radiations follows the changed aboveboard rule, which is to say the added abroad you are from the source, the weaker they get and they do so quickly. You can assure yourself with space. I acclaim you breach at atomic 75 centimeters (30 inches) from your terminal and at atomic one beat (40 inches) from added terminals.

VDT. Accumulate it fixed. X-ray and added radiation assembly increases badly aback the VDT is damaged, breach maintained, or aloof apparent beat out. PCBs are sometimes arise by absolute old VDT models (ie congenital afore 1970).

Animal Set-Up

Posture. No one aspect is perfect. You do not accept to be "military" but accepting able is essential. Footrests help, (or a book or cafeteria dustbin or annihilation accessible to blow your anxiety up a bit), as do cushions if your armchair is not accouterment able support. The best important aphorism is to abstain abiding positions. Agitate your calmly and amateur now and then. Accumulate lose.

Eyes. Afterwards acceptable lighting and alienated glare, the best important eye appliance is to attending abroad from the awning occasionally. It absolutely helps. Also, don't balloon to blink. Blinking moistens the eyes to anticipate afire from dryness.

Warm up. Aloof as an amateur prepares for the bold by accession and alleviation the joints and anatomy to anticipate abrasion and enhance performance, you too should adapt for a chase affair surfing the Net. Do

some accept rolls, abutting stretches, wrist wiggles and leg stretches afore you alike log in. Prevention is bigger than repair.

Breaks. If you authority any allotment of you in one position for best than an hour, you set your cocky up for annealed joints, achy muscles, bond fatigue and bond weakness; not to acknowledgment decreased ability and beneath concentration. If you are focused on what you are doing, you can afar clue of time unless you advisedly agenda breaks. Accept the computer anxiety on screen, or abduct the oven timer out of your kitchen, or set the anxiety on your watch, or somehow let yourself apperceive about the admission of time. Then, at atomic already an hour, (every bisected hour would be better), get adapted up off your bench and airing around, stretch, yawn, wiggle, breath, get the claret abounding and activate the joints. It is account the time and agitation as you will feel better, assignment bluff and get added done. Booty advantage of un-scheduled "downtime". Instead of staring at the little hour-glass and adulatory it would go faster, do commodity benign for your body.

If you already accept automated anatomy problems, such as abutting arthritis or carpel adit syndrome, it is all-important to booty breach added frequently; on the acclimation of three or four mini-breaks per hour. Preventing a flair-up is far aloft to acid these disorders.

I apprehend afresh Jeff Atwood's column on Computer Workstation Ergonomics and I accomplished that I absolutely didn't apperceive a lot of things that were important for my health. For the aftermost brace of months I started alive at home and I assignment the affliction accessible way - I sit in my bed captivation with my laptop in my lap (this is why they alleged it "laptop" isn't it?).

Unfortunately, it isn't funny at all. My aback is aching awfully and now I apperceive the capital acumen for that - my angled alive pose. So I did a little assay and I am giving you some links to sites with absolute advantageous advice about computer ergonomics and a lot of cartoon and pictures.

Snowcrash designer Ilkka Terho comments on the design of the Netsurfer thus: 'When we got the first computer in our office, a big slow thing, we were more or less playing around. We wondered why it just sat on the table. There was the technology and there was the furniture, but there was no connection. It was just the time when people started buying computers for their homes but nobody was doing new sorts of furniture. We began to test out different ideas using bits of furniture in our very messy office. We came up with this idea based on a motorcycle and the way you have the engine between your legs. It was a bit tongue in cheek - all those phrases like the information highway were in the air at the time.'

How to help the tired eyes of the work?

2008-04-21T05:29:00.000-07:00

Many people complain that when working with a computer or documentation they have very tired eyes. If at the end of the working day watering eyes, and blurred objects surrounding it - symptoms asthenopia, excessive stress view.

No, it turns out the cause of these feelings can be no eye disease, and psychological discomfort.

Italian scientists have screened more than 200 bank employees, who complained that the work makes them overly strain the eyes. It turned out that one third of cases the problem can be expressed in words "from work if there is no satisfaction, and then look at it once again did not want"

Scientists have determined that a lack of social support, the conflicts in the working group, low self-esteem and lack of satisfaction from the work performed have a greater impact on the eye than illumination facilities.

Now, if in a room is noisy and it is filled with smoke, tired eyes, even with complete harmony in the team. But officials who worked with pleasure, reported problems with the eyes tripled reduced but were in the same premises.

If you are familiar with the problem - think, perhaps, the entire fault of psychological discomfort? The next question - Is not someone else's feeling today from your approval? "Share your smile" - or your employees as one of a type "easier to hire and dismiss new"? Then it is time to change jobs.

But, even if the work as a whole is OK, to the tender roses thorns attached. Each of us there moments when nainudneyshey had to deal with routine - and not do without them.

What steps can be taken to ensure that at the end of the working day still to look forward into the future?

First of all, it is necessary to properly organize a job. The eyes glare monitor very tiring, so if possible try to get rid of them.

Place the monitor away from the windows. Turn off or it enclosed ceiling light, use the protective shield.

Put the display screen so that look at it from top to bottom at an angle of 10-15 ° to the horizon;

Place documents with which you work, closer to you do not have to change the focal length of eyes, switching from screen to paper. Use paper holder;

Remember to wash the dust (and fingerprints:) with the monitor screen.

Reduce brightness. If the image on the screen display blurry, dark or twinkles immediately adjust the monitor;

The optimum distance from the eyes to the monitor - about 60 Ustroytes see on the stool handy, pay attention to the shoulders were relaxed, neck - is not extended dislocation, and relied on spin comfortably back. This is very important because muscle tension inevitably leads to a voltage of the eyes and headaches.

Preferably, on average, every 2 hours to do relaxation exercises on the neck and back muscles - spinning head, shoulders move, shifting several times. This will allow to reset the accumulated strain.

Exercises for tired eyes

2008-04-21T05:04:00.000-07:00

A couple of minutes relaxed look "nowhere", the best - in the fog gave at the window. There is no need to "fence", as sharp-sighted mountain eagle - quietly and breathe slowly morgayte, happy life as a cow.

There are useful to blink. Most people, ie, "exhibit eyes" - neck extended forward, not flashing eyes peering hard to monitor (paper, TV - choice). Check convenience of a time and still come back to relax situation.

Take convenient , to lean elbows on the table, palms lay down " kovshikom" and uprite their forehead. Closed eyes blows to the base of the palm. Before the eyes flash colored abstraction? Try to "see" something totally black - black velvet, black cat, a soft black hat. At first sight rarely produced. But this exercise is well relaxes your eyes and prevents deterioration of view. By the way, if you are afraid to spoil make-up - keep in mind that sometimes eye fatigue associated with irritation due to cosmetics.

Preferably, on average, every 2 hours to do relaxation exercises on the neck and back muscles - spinning head, shoulders move, shifting several times. This will allow to reset the accumulated strain.

I remember that even the most dull and endless work once all the same ends. Do not rush it - and not nervous, you do not help the cause and harm themselves. In the end, this point - the only one in the life of another such will never, and even if all the bad - try to relax and enjoy.

It's bigger for your aback than sitting. The bench is angled hardly and your legs are supported, abating burden from your bench and adjustment your spine. Halfway amid sitting and standing. In this position you're in the archetypal airy aspect that is affected in aught gravity. This is the best accustomed aspect you can accept that distributes your weight evenly. The Stance is the alone ergonomic armchair that allows you to accept this posture.

Kneeling Reclined Standing

Like the aloof position, but with added weight on your knees and heels kicked up. It takes the accent of your aback and your anxiety at the aforementioned time. This is one of the best different of the four postures. It provides optimal claret flow, improves respiratory action and alleviates any burden on your buttocks.

Netsurfer Ergonomic Computer Chair

2008-04-20T00:25:00.000-07:00

Swedish design company Snowcrash is responsible for this ergonomic masterpeice which it has dubbed the Netsurfer. The semi-reclined seating position has the neck, arms and legs all supported in such a way that it is comfortable for extended periods of internet, game or computer usage. The major drawback is the price - $2790. Snowcrash designer Ilkka Terho comments on the design of the Netsurfer thus: 'When we got the first computer in our office, a big slow thing, we were more or less playing around. We wondered why it just sat on the table. There was the technology and there was the furniture, but there was no connection. It was just the time when people started buying computers for their homes but nobody was doing new sorts of furniture. We began to test out different ideas using bits of furniture in our very messy office. We came up with this idea based on a motorcycle and the way you have the engine between your legs. It was a bit tongue in cheek - all those phrases like the information highway were in the air at the time.

Flexible Keyboard

2007-08-06T21:46:00.000-07:00

The Flexible Keyboard is sort of an odd, yet very interesting gadget. Just like the name says it is a flexible keyboard which can easily be rolled up and carried with you.

The keyboard is perfect for portability and it’s also incredibly durable. It is constructed of high quality silicon which makes it very flexible yet tough enough to be shoved into a laptop bag so you can always have a good keyboard with you if you can’t stand the flat keys on laptops.

The keyboard features all the standard keys of a regular keyboard. The keys are also very well designed as they have soft touch technology which makes your typing silent so you can use it anywhere and not disturb anyone. This also makes it much more comfortable than tapping away at traditional keyboards.

Also since it will most likely be carried around with you it is dust and moisture proof so you don’t even have to keep your backpack or bag clean to carry it ;). It’s also perfect for laptop use as it plugs into your USB port if you don’t have a PS/2 port.

12 Tips for an Ergonomic Computer Workstation

2007-07-30T22:51:00.000-07:00

1. Use a good chair with a dynamic chair back and sit back

2. Top of monitor casing 2-3" (5-8 cm) above eye level

3. No glare on screen, use an optical glass anti-glare filter where needed

4. Sit at arms length from the monitor

5. Feet on floor or stable footrest

6. Use a document holder, preferably in-line with the computer screen

7. Wrists flat and straight in relation to forearms to use keyboard/mouse/input device

8. Arms and elbows relaxed close to body

9. Center monitor and keyboard in front of you

10. Use a negative tilt keyboard tray with an upper mouse platform or downward tiltable platform adjacent to keyboard

11. Use a stable work surface and stable (no bounce) keyboard tray

12. Take frequent short breaks (microbreaks)

A computer chair worthy of The Matrix

2007-07-30T22:50:00.001-07:00

Calling the "G-Tech Neber" ergonomic is like saying Al Gore is an environmentalist. But to truly appreciate the understatement, you need to see a photo of this unique piece of computer furniture, if not actually sit in it.

Shiny Shiny describes it as "part dentist chair," but the "Personal Computing Environment Station" has a lock on that hybrid. We think it actually bears a closer resemblance to the "Alternative Computer Control System" featured awhile back, mostly because of their curved frames.

Regardless of how well the Korean-made Neber compares, at least it has a more creative moniker than the pedestrian names bestowed on the other chairs. Can we assume that it has something to do with the Nebuchadnezzar of Matrix fame? We can just see Neo in one of these, head plugs notwithstanding.

Aviator Laptop Stand

2007-07-30T22:48:00.000-07:00

How often do you think about the way that you sit behind your computer? Unless you have back problems, shoulder, wrist or neck issues — you probably don’t think about it at all. I came across the Aviator Laptop Stand the other day, and it is one of those products that makes you say, “Why didn’t I think of this?” It is so simple, and yet so effective that you will use it everywhere you use your laptop.

The Aviator Laptop Stand was made for the airplane as the name implies - in fact, it fits perfectly on the little tray that folds down on the airplane (with some space left to place your snack on the tray too). But it is also useful in many other environments. As I wrote this review the Aviator was on the edge of my coffee table. It actually gives you more space and tilts the keyboard slightly so you can sit back and enjoy yourself, making sure you stay in good posture. Because it elevates the laptop, the air circulates under the computer keeping the battery from getting too hot while you work, watch your movie, etc.

This stand can accommodate any size Laptop you may have. I used it on tables, my desk, even the floor just to give it a test drive. There are rubber rails that prevent the stand from sliding around. It snaps together, and comes apart easily. When it is folded together the plastic molding allows the pieces to connect to one another.

The Aviator slides right into my briefcase with ease. I forgot it was even in my briefcase when it was stored away. The Aviator Laptop Stand sells for $19.99 and you can find it at www.keynamics.com.

Stop Back and Neck Pain from Long Sitting- Desk, Trains, Planes, Cars, Buses, Computers, Internet Cafe, and TV

2007-07-30T22:35:00.000-07:00

Long sitting can result in upper and lower back pain. But it doesn't have to. Most lists of instructions for sitting without hurting your back tell you to sit in exact ways at exact angles. Instead, this article will show you the concepts of how and why strain and injury occur when sitting so that you can sit in healthy ways that are comfortable and easy.

Why Is Slouching Bad?
Sitting with a rounded back does several things to cause injury and pain. Rounding forward (slouching) when sitting holds the muscles in a longer than normal position, which weakens them. It also slowly degenerates your discs, the little cushions between your back bones (vertebrae), and pushes the discs outward to the back. This is how discs herniate, also called a slipped disc. A slipped disc can bulge outward enough to press on nearby nerves, sending pain down your leg. This is called sciatica. This is easy to prevent.
A problem is that many kinds of seats have a round (concave) back. It's common to sit in these round chairs and allow your back to round to fit the round chair back.
Worse, many people not only round into the chair back but round further by hunching forward of the chair or putting a pillow behind their head which only pushes the head further forward.
Another common way to hurt your back sitting is to sit toward the middle of the chair, and create a "hammock" out of your spine, sagging between the buttock and the upper back. Your body weight presses down on your low back discs.
Simple Pain Prevention
Instead of sitting forward in your chair, move your hip all the way to the back of the chair, and lean back in comfort. If the chair back is rounded, put a small cushion in the space between your low back and the chair, to preserve healthy normal back posture instead of assuming the curved posture of the chair.
Making a Lumbar Roll
To feel the right size for a lumbar roll, sit back in a chair and nestle your forearm behind you in the natural lumbar space between your low back and the chair. Lightly press your upper back against the chair so that the low back does not press your arm, but rests lightly. It should feel comfortable. Your forearm is usually about the right size for a lumbar roll.

Many things can work for a lumbar roll. There are commercially available rolls including inflatable ones that pack flat. When traveling you can use many common soft items. Try a small folded towel, shirt, or gloves. Fold your jacket, just enough to be the size you want. Commercial lumbar rolls are usually a roll of foam. If it is too large, it will not be comfortable. You can cut a roll lengthwise

Using the Lumbar Roll - Lean Back, Not Forward
Don't use a lumbar roll that feels too large. It will be uncomfortable. If you fell like it is sticking you in the back check to make sure you aren't rounding against it, or that it isn't too large, or extending too high or low on your back. Lift your upper back against the chair instead of pressing against the roll. Don't force into unnaturally straight or arched posture. Keep head up, not tilted or craned forward.
Long Sitting When Driving
- Use a lumbar roll, described above, if needed.
- Sit with your hip at the back of the seat, not the middle.
- Move the seat in. People often sit with the chair so far back that they round forward to reach the steering wheel. Move your seat in closer. Tilt the seat slightly backward. Sit up and lean back against the seat, instead of craning and rounding. A bonus to moving the car seat forward is that by sitting back instead of reaching forward, your chest and face are farther from the airbag, said to be safer.

Long Sitting at Your Desk
- Use a lumbar roll, described above, if needed.
- Sit with your hip all the way against the back of the chair.
- Move the seat in and sit closer to the desk so you can sit up instead of hunching forward.
- Put the monitor up on a book, block, or shelf. Use an external keyboard for laptops.
Long Sitting for Buses and Flights
Commercial airline, bus and train seats are often rounded, encouraging prolonged, forced rounding.
- Use two pillows, one in the natural curve of your low back, and the second above that one for your upper back, in the space still left by the rounded seat. Sit upright and lean back to rest the back of your head against the head rest.
- Flights sometimes have a video message encouraging in-seat stretching. Often the advice is forward bending. That is the last thing you need after sitting bent forward for so long. Instead, stretch your back and shoulders backward, not forward. Pull your chin in while leaning back. Breathe.

Sitting for Relaxing
Instead of sitting rounded in soft chairs and couches, use a pillow or other cushiony object to pad the space between the normal inward curve of your low back and the chair.
Don't Forget To Get Up
No matter how well you sit, it's still a lot of bending at the hip. Many people get shortened muscles at the hip from this. Short, tight hip muscles add their own posture and achy hip and back pain problems. Stand up and straighten out. Tip your hip under you to straighten it from the bent "behind-stuck-out" position.

Another nice stretch to straighten out after house chores or exercise is to lie face down and prop up on elbows. Don't pinch or crane your back or neck, just gently stretch the entire spine and hip the other way.
No Strange Rules
It is common to hear that you must sit at 90 degree angles or hold your thighs parallel to the floor, or other strange, strict rules about positioning your arms or legs.

Don't worry about exact angles. Get the concepts, then you can keep healthy posture while you go about your life. Most important - don't sit frozen in place. Movement is important for joint health. Joints don't have much blood flow. They get nutrition in and waste out by physical movement. Move freely in your chair instead of sitting still for hours at a time.

Sit in healthy position whether the chair has straight back, a round back or no back. You are the one to determine your positioning. Keep it simple. Sit preserving the small inward curve of your back and you will prevent injury and get up after long sitting with straight happy position and no pain.

Anti-gravity ergonomics

2007-07-22T06:38:00.000-07:00

This is an interesting looking device. Some kind of fully floating computer controlled ergonomic workstation, suppossedly designed by a “group of researchers involved in medical research for persons with spinal cord injury”.
The multifunctional GRAViTONUS® system allows moving the user in space freely. It comes with an on-board computer which constantly analyses positions of a body, measures local temperature and pressure on different body parts. The system adapts to the user depending on his or her psychophysical activity thus creating maximum comfort, anticipating his or her desires.

Sit right at your computer - includes ergonomic checklist

2007-07-20T23:54:00.000-07:00

rapid advances in microchip technology have produced yet more changes in the ways that people work, play, shop and conduct other activities, along with increasing health problems from sitting all day staring at flickering screens and punching keyboards.
Computer use brings ergonomic health concerns
Ergonomics -- a term barely heard until recently -- has become a trendy catchword used to sell products such as car seats ("ergonomically perfect for human backs") or office chairs ("with optimal ergonomic comfort"). The science of ergonomics deals with work environments and the relationship between humans and their equipment. Biomechanical principles are used to design machinery and tools that are safer and healthier for those operating them. For example, keyboards and other fine hand-tools are best used with straight wrists in a "neutral" position to lessen injury risks. Additional ergonomic features to consider include back posture, head-tilt, the heights and types of work surfaces, seating arrangements, visual angles and illumination. (Tools for women should have different dimensions from those used by men.)
"Repetitive strain injury" a mysterious modern malady

U.S. statistics suggest that musculoskeletal aiments rank first among job-related injuries and compensation claims. The U.S. National Institute for Occupational Safety and Health found the incidence of work-related musculoskeletal disorders in some occupations, particularly among newspaper reporters, as high as 40 per cent.

Repetitive strain injury describes work-linked musculoskeletal disorders involving pain, discomfort and muscular weakness, sometimes along with tissue swelling. (Alternate terms include "overuse syndrome" and "cumulative trauma disorder.") The rise in musculoskeletal disorders is attributed to poor posture, inefficient work habits, lack of ergonomic planning and repetitive movements (as in keyboarding or assembling small parts). But accurate diagnosis is tricky because, apart from occasional swelling, it depends on subjective descriptions, rather than detectable or measurable signs of injury. Improving posture and muscle tone (with appropriate exercise) can reduce the incidence of muscle strain.

Prevention is a must because many of those afflicted can take ages -- weeks or months -- to recover, and the condition often worsens or improves without rhyme or reason. Therapy includes physiotherapy, biofeedback, movement retraining, EMG (electromyography) and other strategies. (One Toronto newspaper journalist had to switch to a costly, slow, voiceactivated computer rather than a faster keyboard-operated one.) People must also take care not to reinjure themselves.

Keyboarders need frequent mobility breaks

Frequent breaks for muscle stretching and mental variety are vital for VDT users, not only to move the muscles but also to reduce fatigue and promote social interaction. Short, frequent breaks seem better than occasional long ones. Although there are no strict rules, many ergonomists suggest a five to 10 minute break after each hour of computer work. Studies show that even 10 per cent of VDT working time can be spent in rest periods without lowering productivity. On the contrary, frequent breaks increase efficiency. Pauses are best individually negotiated rather than by strict protocol.

Flexibility is the key to ergonomic health

Although immobility is one factor in muscular strain, badly placed equipment and poor design contribute. "In wading through the mass of supposedly ergonomic products," warns one expert, "remember that in this evolving field the best bet is: buyer beware!" There's no need to spend a fortune on office improvements -- simply ensuring good adjustability and reorganizing existing furniture, perhaps purchasing a few inexpensive items (such as footrests, lamps or document holders) may suffice to make VDT use ergonomically healthier. The idea is to arrange things so that the body works in a manner least likely to cause muscular strain. Parameters set by American National Standards Institute emphasize that VDT tables and chairs should be easily adjustable, as operators differ in size and shape. Document holders and viewing screens should be adjustable and keyboards detachable -- so they can be put in any desired position.

Sitting, especially for hours on end, is very hard on human backs and exerts a far greater load on the spine than standing still or walking. The right chair is a key element in ergonomic wellbeing. Thighs should be roughly parallel to the floor, feet flat on the floor or on a footrest. Seating too low pressures the thighs; having the seat pan too high puts unwanted pressure on the back of the knees.
http://findarticles.com/

Ergonomic concerns about VDT use surfaced in the 1970s because of a dramatic increase in operator complaints of muscle strain, particularly in the back, neck, shoulders and wrists -- partly blamed on the nonstop tempo of today's keyboarding. Rapid action of fingers on keyboards for hours on end can inflame parts of the hand and/or wrist, pressing on nerves, possibly producing pain and tingling. Other health problems arise because modern equipment eliminates many of the movements previously entailed in keyboarding, abolishing the opportunity to move and stretch the muscles.

Your computer may be a pain in the neck

2007-07-20T23:13:00.000-07:00

Sit up straight.

If you're reading this article with hunched shoulders and a craned neck, your "computer slump" could one day give way to what some physical therapists call "postural syndrome."

Postural syndrome is essentially repetitive stress to the neck and thoracic spine, or the 12 vertebrae of the mid-back and chest area, from the so-called flex-forward position. Doctors and physical therapists say that the injury commonly targets the fourth, fifth and sixth discs in the thoracic spine, leading to muscle tenderness, stiffness or, in some cases, nerve irritation.

A prolonged slouch over many years causes the disc space to narrow, which in turn can cause nerve irritation that spreads underneath the shoulder blades, down the arms and down the back.

Sure, most office workers and their ergonomic specialists are familiar with the dangers of repetitive motions with a mouse and keyboard at the PC all day, resulting in weakened wrists, tennis elbow or, worse, carpal tunnel syndrome. But some physical therapists say that such injuries lately are taking a backseat to patient complaints of pains in the mid- to upper back and neck.

"We call it the flex-forward posture, where your head's jetting forward, the abdominals shut down and the majority of the pressure comes to the mid-back," said Caroline Palmer, a physical therapist at the Stone Clinic, based in San Francisco. "Your spine is going to have to give somehow."

Kids on computers

2007-07-20T23:01:00.000-07:00

If you're like a lot of kids, you probably spend time sitting at the computer, doing schoolwork or playing games. But whether you're writing a report about aardvarks or zapping aliens, using a computer can be tough on your body. How?

Sitting for a long time in positions that aren't natural for your body can strain your hands, wrists, back, and eyes. Over time, this can result in pain and a kind of injury called a repetitive stress injury.

The Four Best Ways to Sit at Your Computer

2007-07-18T09:55:00.000-07:00

The reality of modern day information work is that most of us spend a good chunk of our time each day seated in front of a computer. I'm big on time maximization so my feeling is that if we're going to be on a computer all day why not make the best of it. The problem with poor posture is that eventually over time it leads to injury.
Part of my reason for writing this is personal. My Dad has been a computer programmer all his life and when he was in his early 40s he started having major back spasms which pretty much ended any athletic activity for him. And he is just one of many…did you know that there are over 200,000 hip replacement surgeries each year in the U.S. alone?

So if you're interested in not going down with a back/hip/whatever injury later I encourage you to continue reading…
#1 - Exercise ball - Apparently very popular with the folks at Google. It's pretty tough to slouch on an exercise ball (actually you will probably fall off). Plus it keeps you active throughout the day because you have to do a little “micro-balancing.” The other thing that I like (yup, I'm a dork) is stretching while at the computer. You can actually do a pigeon pose that feels really good and loosens up your hips. The main consideration here is to make sure that your chair is the right height. There's a chart on this page that will help you choose the best ball based on your height.
#2 - Kneeling chair - I have a kneeling chair at the office and really dig it. It keeps your spine erect and is very comfortable to sit in. You definitely can slouch but if you sit on the chair properly you probably won't find yourself doing so very often. If you're going to get a kneeling chair I'd highly recommend springing the extra dough for the Tempurpedic version. Your knees will thank you for it!
#3 - Lotus position - This is a method I haven't experimented much with but would like to in the future given how good sitting cross-legged is for the hips. The major obstacle here is that you either need some sort of platform to sit on if you're going to use your regular desk or you need a desk with a lower height if you're going to sit on the floor. Having said that, I think this would be a great way to sit at your PC (especially when at home…probably not so practical for the office…)#4 - Treadmill. OK, this isn't actually sitting…but I stumbled across a great page talking about ”walking while working” and I find this kinda fascinating. We have this huge problem with obesity as a society which could largely be cured if people would walk for a half hour or hour each day. And we have all this time in front of computers reading e-mail and the like where technically we could be walking. Hmmm… I noticed that one of my favorite bloggers (Jason Calacanis) was recently talking about this and so maybe we can start a trend. Can you imagine if corporations created fitness rooms with treadmills and docking stations for peoples' laptops. That would be kinda sweet.

Anyway, I'd love to hear feedback on the ideas above as well as any other suggestions for healthy ways to sit at a computer. Feel free to post comments below or e-mail me at jon at learnoutloud dot com. Thanks!

The best way to sit at and use your computer

2007-07-18T08:59:00.000-07:00

Introduction

While most people using Everything2 sit at a computer to do so, research has shown that many of these people do not sit correctly, or work under suboptimal conditions. The result is not unusual: Carpal Tunnel Syndrome, back and neck pains, eyestrain, and headaches. The strange thing is that many people simply accept these (often minor) aches and pains as a result of using a computer, when in fact these annoyances are easily avoidable with a little planning and effort. The following sections cover various different aspects of sitting at and using your computer, and should, if followed correctly, make your computer experience far more pleasant.

Placement of your computer in the room

One of the major cause of eyestrain when using a computer can be attributed to glare. Therefore, your computer screen should not be directly next to or directly opposite a bright light or window. Reflected glare can make it difficult to make out what is seen on the screen, and having your eyes constantly adjusting to a bright light directly next to your screen can lead to tension headaches. If necessary, move the light source to another part of the room or invest in heavy curtains. Anti-glare screens can help, but tend to make the text on the screen fuzzy and difficult to read. If you are in an office situation, then check with your IT department before moving equipment - moving equipment without permission can constitute a breach of your IT policy. If necessary, speak with your manager, as new curtains are often a small price to pay for increased productivity and decreased medical fees.

Placement of your computer on your desk

Your computer (particularly your monitor, keyboard and mouse) should be at a comfortable height for you when you sit down. This means that your elbows are just above the desk when you sit down at it, and your monitor should be raised if necessary so that you look at it straight on, without having to look down or up. Your feet should be able to rest comfortably on the floor. Your computer should be square with the edge of your desk, so that you do not have to lean in any direction to use it. Your keyboard should not be obstructed with bits of paper, and you should use a mousepad to keep your mouse moving smoothly. The use of cable ties to tidy up the cables running around and behind your desk can make a big difference to the neatness of your work area. If cables are a big problem, wireless keyboards and mice are relatively inexpensive, and newer models use up very little battery power, meaning that a single set of batteries can last for months at a time. When buying a keyboard, try and get one with a wrist rest, as these do cut down on wrist problems.

How to Sit at Your Computer for Hours Without Pain

2007-07-18T08:53:00.000-07:00

How long can you sit at your computer without hurting? Thirty minutes? Sixty minutes? Sitting for prolonged periods with poor body positioning can be very fatiguing. Over time, the fatigued area becomes strained and pain sets in.

With a correctly configured workstation you should be able to sit for hours without hurting your back, neck, arms, or wrists. Below are the recommendations I give my patients to help them achieve correct ergonomics or body positioning.

Choosing a well-designed office chair is an essential step in achieving good computer ergonomics. A good chair will preserve and support the natural curves of your back. In the neck and low back the spine curves in, and in the middle back the spine curves out. To perform well the contour of the chair's back should match the curves of your back. (See the "Good vs. bad computer posture" drawing by clicking on the link in the resource box.) This support keeps you from slouching when you sit.

A taller seat back is better than a shorter one. The lower portion of the seat back should support your lower back's inward curve, and the upper portion should support your middle back's outward curve.

Sit all the way back in your chair so the seat back can do its job of supporting the curves of your spine.

A good chair must be well padded. I've seen trendy "mesh" chairs in office-supply stores but have never found one that was satisfactory. Mesh chairs are too stiff and hard. Nothing beats old-fashioned foam padding in a chair. The seat cushion should fit your body and be well padded.

Your legs should be parallel to the ground; and those with short legs may need a footstool. A chair that reclines offers a good change of position that can help prevent fatigue. Reclining allows you to change positions and still receive the support of a well-contoured seat back.

Once you have a properly supporting chair, you can turn your attention to the desktop.

One of the most common computer workstation errors is poor monitor placement. A correctly positioned monitor will help you to avoid neck and shoulder pain. The ergonomic principle here is to keep your head and neck in a neutral position: This is accomplished by looking straight ahead. You don't want to look up and down, and you don't want to look left and right.

You keep your head from looking up and down by keeping your head and eyes level. This is accomplished by raising the computer monitor so that your eyes hit the screen three quarters of the way up (See the graphic in the resource box.) A level head keeps your neck muscles from having to constantly contract to hold your head in a poor position.

You keep your head from looking left and right by placing the monitor directly in back of the keyboard. This avoids the common practice of placing the monitor off to the side. This side positioning causes your neck to stay constantly turned leading to stressed muscles in your neck and shoulders.

Next, the keyboard must be low - almost in your lap. This allows your shoulders to stay close to your side and remain relaxed. Placing the keyboard too high forces you to constantly contract the muscles of your shoulders so your forearms can reach the keyboard. If your chair has "arms" you can position the keyboard a little higher so long as the chair's arms support your forearms. But if your chair does not have arms, position the keyboard close to your lap so your forearms can be positioned down by your side.

Your wrist should be relaxed and straight or slightly flexed (curved down). The mouse should be right next to the keyboard. And finally, be sure to take regular breaks.

Laptops are an ergonomic nightmare because the keyboard is right next to the monitor. But the solution is simple: purchase an extra keyboard to "separate" the monitor from the keyboard and position each as described above.

There are many ergonomic devices available, but you needn't spend a lot of money on them. A monitor stand not only raises the monitor, but it has the added benefit of freeing up space under the monitor. However you can save this expense and just use a couple of thick phone books.

You can purchase a keyboard tray to lower the keyboard to your lap, or you can simply place the keyboard on your lap. Placing the keyboard in your lap works well when you recline the chair back.

The office chair is the most expensive ergonomic device. But there are good ones that are affordable. Shop around. Go to a few office-supply stores and sit in many chairs until you find the one that fits you best. Pay particular attention to how the contoured seat back supports the curves of your back.

Sitting incorrectly with poor body position at a computer can be very fatiguing. Good ergonomics require a well-designed office chair that properly supports the back, the proper monitor height, a low keyboard, and good shoulder placement to keep shoulders and forearms relaxed. These ergonomic recommendations can lead to hours of comfortable work.

One last thought. These chair suggestions are useful for any seating situation. If you have back pain, sit in a comfortable office chair at home. Don't sit in hard kitchen chairs or slouch on a couch.

Notebook Stand with Integrated Keyboard Brings Desktop PC Experience to Notebooks; Easy to Set Up, Easy to Put Away

2007-07-18T08:38:00.000-07:00

Notebook PCs are fast-becoming the standard PC choice in homes around the world. But the compact form of a notebook PC often comes at the expense of comfort as people assume awkward postures to type on the small built-in keyboards, often with non-conventional key layouts, and stare down at the low-lying screens. The Logitech Alto addresses these comfort issues with a simple, all-in-one solution that opens like a book to reveal an integrated full-size keyboard on one side and an angled platform for the notebook PC on the other. The keyboard gives people the typing experience they are accustomed to having with a desktop PC, complete with a number pad, a media panel and a standard key layout, while the easy-to-set-up platform raises the monitor to eye level and establishes an ideal distance between the monitor and the user's eyes.

Sit at a Computer

2007-07-18T08:20:00.000-07:00

Regular computer users perform 50,000-200,000 keystrokes each day. Under certain circumstances and for vulnerable individuals, frequent computer use that involves awkward postures, repetition and forceful exertions may be related to nerve, muscle, tendon and ligament damage. If you use a computer extensively (several hours each day), many experts recommend that you consider proper workstation layout and posture techniques to minimize your risk of developing injuries of the hand/arm, shoulder, neck and back. Overuse injuries develop over time, and may set in more quickly if you spend long hours sitting at a computer at home, as well as at work.

Computer use injuries

Symptoms of a problem can include numbness in the fingers, sore wrists, lower back pain or eyestrain (redness, dryness, soreness, temporary blurring of vision and headaches). You may also develop general aches and pains in the neck, shoulders, arms, back, thighs and lower legs (postural fatigue) or persistent pain or discomfort in muscles, tendons and other soft tissue (repetitive strain injury).

"An ounce of prevention is worth a pound of cure." Avoid most computer-related overuse injuries. Some experts suggest that to reduce your risk:

Use a properly set-up workstation.

Use correct posture including keyboard and pointing device techniques.

And most importantly, take frequent rest breaks.

Workstation set-up

If you're like most people, you are more productive and efficient at a workstation that fits your body size. Many experts suggest that the ideal workstation lets you work in natural (neutral) postures that may minimize strain on your body. A workstation mismatched with your body may force vulnerable individuals into uncomfortable postures such as hunching over, slouching, straining or twisting. Some believe that working for extended lengths of time in unnatural positions may be related to musculoskeletal injury. These experts note that problems with workstation set-up for some persons may include using a chair that is the wrong height, size or does not support your back and incorrect height of work surfaces (desktop and keyboard), monitor and source documents.

Chair: Many people find that a good chair is one that adapts to their bodies. You may want to choose one that is stable and adjusts easily for height and tilt. Consider a chair with a backrest that supports the curve of your lower (lumbar) back. Sit back in the chair when you work at a computer. Experts suggest that you consider positioning your thighs horizontal with your knees at about the same level as your hips. Rest your feet comfortably on the floor (or a footrest if you need one). Some experts advise that your chair should also:

Support your forearms with adjustable armrests that position your elbows near your waist.

Have a padded seat with a pan at least one inch wider than your hips and thighs.

Slope down slightly and allow a 2-3 finger breath-space between the seat cushion and the back of your knees when sitting.

Consider a base with at least 5 points that roll on wheels (casters).

Work surfaces: Many people may be most comfortable when the height of their desks are about elbow level when sitting down. Check that there is enough room below the work surface to comfortably fit your knees and thighs. Consider having the height of the surface holding your keyboard and mouse or trackball about 1-2 inches above your thighs. Center the keyboard in front of your body. Many experts suggest that when you use a correctly positioned keyboard:

Your elbows stay near your body in an open angle allowing circulation to the lower arms and hands.

Your arms are nearly perpendicular to the floor.

Your wrists are nearly straight.

You may be more comfortable if you use your arm, not just your wrist, to move the mouse. Choose a mouse that fits the size of your hand comfortably and is as flat as possible to minimize wrist strain.

Monitor and source documents: Correct placement of your monitor may help some individuals prevent eye strain, neck pain and shoulder fatigue by keeping your head and neck as straight as possible. Some experts suggest that your monitor should be separate from your keyboard and centered directly in front of you. Position the monitor:

About one arm's length (20-26 inches) away.

With the top of the viewing screen at eye level so you can see it clearly without looking up.

Position a document holder between the monitor and keyboard or right next to the monitor to avoid twisting your neck to view source material. Additional workstation considerations:

Locate your workstation away from sources of glare such as windows.

Organize your workstation so the objects you need most often are within easy reach.

Some find it helpful to use a head set if you talk on the phone and type at the same time.

Posture, keyboard and pointing techniques

When you use a properly set-up workstation, you can sit at the computer in a natural (neutral), relaxed position that may help reduce your risk of developing musculoskeletal injuries:

Spine: Ears are in line with tops of shoulders, and shoulders in line with hips.

Shoulders: Upper arms hang relaxed and close to the body.

Wrists: Hands are in straight lines with lower arms.

Keyboarding and pointing techniques:

Keep your fingers relaxed while typing and using a mouse.

Use a soft touch on the keyboard instead of pounding keys with unnecessary force.

Grasp the mouse gently.

Avoid holding a pen or anything else in your hands while you type or use the mouse.

Relax your fingers and hands between bursts of typing or mousing using a flat, straight wrist posture.

Additional tips:

Don't rest your elbows on hard surfaces.

Rest your eyes occasionally by focusing on distant objects (i.e., look out a window).

Frequent rest breaks

The body is not designed to sit still, even in correct position, for long periods of time. Some individuals find that using a computer extensively can cause discomfort, so regular pauses are not a waste of time. Change your seated position occasionally, stand up or stretch whenever you start to feel tired. Depending upon your work and environment, you may want to take breaks.

Stretching exercises

Basic stretching exercises can help keep limber the joints and muscles you use when you sit at a computer. Some examples:

General: Stand up and stretch your arms over your head.

Neck: Tilt your head to one side (ear to shoulder); hold; relax; repeat on other side.

Shoulders: Slowly bring shoulders up to the ears and hold briefly.

Wrist: Hold arm straight out in front of you; pull hand backwards with other hand, then pull downward; hold; relax; repeat with other hand.

Laptop computers

Some individuals may find the design of a laptop computer is inherently problematic because the screen and keyboard are not in separate places. When you use a laptop, either your head/neck bends to see the screen, or your hands/wrists use poor posture at the keyboard. If you use a laptop frequently, consider buying either an external monitor or an external keyboard to improve the workstation set-up. If you use a laptop only occasionally, you may find that positioning the computer in your lap for the most neutral wrist posture is most comfortable.

How to Set up an Ergonomically Correct Workstation

2007-07-18T08:10:00.000-07:00

If you work or study at a computer for a long period of time each day and you have an improperly set up workstation, you may be risking serious health consequences. Ranging from a stiff neck to repetitive motion disorders, these injuries are painful and can be long-term. Yet, they are easily preventable, if you take the time to set your workspace up correctly. Here are some tips on workspace set-up to help you maintain your postural health and work more comfortably
Adjust chair height properly. Adjust your chair height so that your feet are flat on the floor, with your thighs parallel to the ground and knees at a 90 degree angle. An approximation of the correct height can be found by standing facing your chair, and raising the seatpan to just below your kneecap. If you are too short to have your feet flat on the floor, you should place a footrest under your feet and adjust the chair properly from there.
Set chair depth. The back of your knees should fall 2 inches (5 cm) from the end of the seatpan, giving room for three fingers between the back of your leg and the chair.
Align backrest It should press comfortably against your back and follow the curves of your back. If your chair will not adjust to the proper setting, you can use a towel to make it fit better.
Set armrests Allow your elbows to form a 90 degree angle with your hands on your keyboard. Take care that your elbows are not winged out, but are at a comfortable, fairly vertical alignment. Your arms should be parallel to the ground and your wrists in a neutral position. If you have a wrist rest, do not use it while typing. It is fine to rest your wrists there when not typing, but when typing your hands should be floating over the keyboard.
Flatten keyboard on the desk. If there is a setting that lifts the back of the keyboard, do not extend it.
Place mouse near keyboard . Do not use a wrist rest on a mouse pad. Although it may seem like a good idea, it has been shown to increase a person's risk of Carpal Tunnel syndrome.
Adjust height of monitor. Place the monitor so that the entire screen sits below eye level. The average computer is designed for someone the size of the typical 25 year old man. It is likely that you are not this exact, "ideal" size, so make any necessary adjustments.
Arrange items within reach. Place your phone, writing equipment, books and other frequently used items within easy reach from where you sit. You should not need to stretch to reach frequently used objects.
Tips

When typing from a document, it is best to have it on a stand as close as possible to the screen. You can also obtain an arm to attach to the computer that holds the document at eye level, so you only have to move your eyes to read from it.
Make sure the lighting and monitor position is such that there is no glare on the screen when you are facing it directly.
Try to move as frequently as possible to avoid staying in one place. Get up to shred a document or get a paper off the printer.
An old phone book makes a great footrest if you can't purchase a ready-made one. You can adjust it by tearing out or adding pages!
It is a good idea to stop typing and stretch or walk about every 30 minutes. If you forget, set an alarm on your computer, watch, phone or other instrument to remind you.

How to Sit at a Computer

2007-07-18T07:47:00.000-07:00

Sitting at a computer for long periods of time, can take a toll on your body. By not sitting in the correct positions, it is easy to end up with back pains, knees pains, and a tingling of the hands and fingers. This could easily turn into Carpal Tunnel Syndrome. At times, this pain becomes so severe and painful that surgery is the only option.
Steps
Push your hips as far back as they can go in the chair. Adjust the seat height so that your feet are flat on the floor and your knees equal to, or slightly lower than, your hips. Adjust the back of the chair to a 100°-110° reclined angle. Make sure that your upper and lower back are supported. If necessary, use inflatable cushions or small pillows. When your chair has an active back mechanism use it to make frequent position changes. Adjust the armrests so that your shoulders are relaxed, and remove them completely if you find that they are in your way.
Sit close to your keyboard and position it so that it is directly in front of your body. Make sure that the keys are centered with your body.
Adjust the keyboard height so that your shoulders are relaxed, your elbows are in a slightly open position, and your wrists and hands are straight.
Understand that the tilt of your keyboard depends upon your sitting position. Use the keyboard tray mechanism, or keyboard feet, to adjust the tilt. If you sit in a forward or upright position, try tilting your keyboard away from you, but if you are slightly reclined, then a slight forward tilt will help to maintain a straight wrist position.
Use wrist rests to help maintain neutral postures and pad hard surfaces.
The wrist rest
should only be used to rest the palms of the hands between keystrokes and not while typing. Place the pointer as close as possible to the keyboard. Placing it on a slightly inclined surface, or using it on a mouse bridge placed over the 10-keypad, can help to bring it closer. position.

Understand that incorrect positioning of the screen and source documents can result in awkward postures. Adjust the monitor and source documents so that your neck is in a neutral, relaxed position. Center the monitor directly in front of you, above your keyboard.Position the top of the monitor approximately 2-3” above your seated eye level. If you wear bifocals, lower the monitor to a comfortable reading level.

Sit at least an arm's length away from the screen and adjust the distance for your vision. Reduce any glare by carefully positioning the screen, which should be at right angles to the windows. Adjust any curtains or blinds as needed. Adjust the vertical screen angle and screen controls to minimize glare from overhead lights.
Position the source documents directly in front of you, and use an in-line copy stand. If there is insufficient space then place the documents on a document holder positioned adjacent to the monitor. Place your telephone within easy reach. Use headsets and a speaker phone to eliminate cradling the handset
Tips

An articulating keyboard tray can provide optimal positioning of input devices. However, it should accommodate the mouse, enable leg clearance, and have an adjustable height and tilt mechanism. The tray should not push you too far away from other work materials, such as your telephone
If you do not have a fully adjustable keyboard tray, you may need to adjust your workstation height and the height of your chair, or use a seat cushion to get in a comfortable position. Remember to use a footrest if your feet dangle.
Take short 1-2 minute stretch breaks every 20-30 minutes. After each hour of work, take a break or change tasks for at least 5-10 minutes. Always try to get away from your computer during lunch breaks.
Avoid eye fatigue by resting and refocusing your eyes periodically. Look away from the monitor and focus on something in the distance. Rest your eyes by covering them with your palms for 10-15 seconds. Use correct posture when working. Keep moving as much as possible.
Avoid using excessively wide wrist rests, or wrist rests that are higher than the space bar of your keyboard.
Other techniques to reduce glare include use of optical glass glare filters, light filters, or secondary task lights

Eyestrain and your computer screen: Tips for getting relief

2007-07-18T07:31:00.000-07:00

Although not associated with long-term consequences, eyestrain resulting from computer use can be bothersome and uncomfortable — and may cut your work short. Minimize computer-related eyestrain by following these tips.

Your eyes hurt. Your head aches. And there you sit, peering at your computer monitor. If you're one of the many people who use computers every day — either for work or personal use — you may experience eyestrain as a result.
Eyestrain: Signs and symptoms

Common signs and symptoms include:
Sore, tired, burning or itching eyes
Watery eyes
Dry eyes
Blurred or double vision
Headache and sore neck
Difficulty shifting focus between monitor and paper documents in your work area
Color fringes or afterimages when you look away from the monitor
Increased sensitivity to light

Eyestrain associated with computer use isn't thought to have serious or long-term consequences, but it's disruptive and unpleasant. Though you may not be able to change the nature of your job or all the factors that can cause eyestrain, you can take steps to reduce the strain.
New habits can help relieve eyestrain

A few simple adjustments in how you work or surf the Internet can give your eyes a much-needed rest.

Follow these simple tips to reduce eyestrain:
Take eye breaks. Throughout the day, give your eyes a break by forcing them to focus on something other than on your screen. Try the following exercise: Hold a finger a few inches in front of your face; focus on the finger as you slowly move it away; focus on something far in the distance and then back to the finger; slowly bring the finger back toward your face. Next, shift your focus to something farther than eight feet away and hold your eyes there for a few seconds. Repeat this exercise three times, several times a day.
Change the pace. Try to stand up and move around at least once every hour or so. If possible, lean back and close your eyes for a few moments. At the very least, try to give yourself a five-minute rest every hour. Do other work, such as phone calls or filing, during this time.
Blink often to refresh your eyes. Because many people blink less than normal when working at a computer, dry eyes can result from prolonged computer use. Blinking produces tears that can help moisten and lubricate your eyes. Make a conscious effort to blink more often.
Consider using artificial teardrops. Available over the counter, artificial tears can help relieve dry eyes that result from prolonged sessions at the computer.
Practice relaxation. Ease muscle tension with this relaxation exercise: Place your elbows on your desk, palms facing up; let your weight fall forward and your head fall into your hands; position your head so that your eyebrows rest on the base of your palms, with your fingers extended toward your forehead; close your eyes and take a deep breath through your nose; hold it for four seconds, then exhale. Continue this deep breathing for 15 to 30 seconds. Perform this simple exercise several times a day.
Get appropriate eyewear. If you wear glasses or contacts, make sure the correction is right for computer work. Most lenses are fitted for reading print and may not be optimal for computer work. Glasses or contact lenses designed specifically for computer work may be a worthwhile investment.

Put your workstation in order

Take some of the strain off your eyes by making sure your desk space is set up in an appropriate and eye-friendly way.

Adjust your monitor. Position your monitor directly in front of you about 20 to 28 inches from your eyes. Many people find that putting the screen at arm's length is about right. If you need to get too close to read small type, consider increasing the font size.

Keep the top of your screen at eye level or below so that you look down slightly at your work. If it's too high or too low, it can lead to a sore neck. If you have your monitor on top of your central processing unit (CPU), consider placing the CPU to the side or on the floor. And if you wear bifocals or trifocals, keep in mind that you may have a tendency to tilt your head backwards so that you can see through the lower portion of your glasses. To adjust for this, consider lowering your monitor a few inches or buying glasses designed for computer work.
Position your keyboard properly. Place your keyboard directly in front of your monitor. If you place it at an angle or to the side, your eyes have to focus at different distances from the screen, a tiring activity.
Keep reference materials nearby. Place reading and reference material on a document holder beside your monitor and at the same level, angle and distance from your eyes as the monitor is from your eyes. This way your eyes aren't constantly readjusting.

Check the lighting and reduce glare. Bright lighting and too much glare can make it difficult to see objects on your screen and strain your eyes. To check glare, sit at your computer with the monitor off. This allows you to see the reflected light and images. Note any intense glare. The worst problems are generally from sources above or behind you, including fluorescent lighting and sunlight.

If possible, place your monitor so that the brightest light sources are off to the side, at a right angle to your monitor. Consider turning off some or all of the overhead lights. If you need light for writing or reading, use an adjustable desk lamp. Close blinds and shades and avoid placing your monitor directly in front of a window or white wall. Use a glare-reducing screen to minimize glare from overhead lighting. Finally, adjust the contrast and brightness on the monitor to a level that's comfortable for you, making sure the letters on the screen are easy to read.

Also wipe the dust from your computer screen regularly. Dust on the screen cuts down on contrast and may contribute to glare and reflection problems.

If problems still persist, it could be a sign of a more serious problem. See your doctor if you have:
Prolonged eye discomfort
A noticeable change in vision
Double vision

But if you're like most people, making a few simple adjustments can help keep your eyes rested and ready.

What's the correct way to do sit-ups?

2007-07-18T06:43:00.000-07:00

Sit-ups can strengthen your belly muscles, but doing them incorrectly can hurt your back. Sit-ups should be done while you lie on your back with your knees bent enough for the soles of your feet to touch the floor. Place both hands on your chest and slowly raise your head off the ground. Then, slowly raise your shoulders around one foot and then lower them to the ground. Do this slowly ten times, rest a few seconds and then do two more sets of ten. After a week or two, this exercise will feel easy, so do it with a light weight, wrapped in a towel, held behind your neck or on your chest. As you become stronger, you can use heavier weights.

There's no need to do more than 30 sit-ups in one workout. To strengthen your belly muscles, you increase the resistance, not the number of repetitions. Keep your knees bent to protect your back. If you do a sit-up with your legs straight, you place a great force on the iliopsoas muscles that increase the arch in your back, which can damage the ligaments and joints. If your belly muscles are weak, you are likely to arch your back excessively when you sit up and increase the chances of injury. If you are doing sit-ups to flatten your stomach, you need to raise your head only about one foot because going higher than that uses the quadriceps muscles in the front of your upper legs, not your belly muscles.
