Flexible Keyboard

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

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

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

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

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

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

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

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

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

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

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

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.

The necessary rules using the computer, which needs to know even the novice user, the following :

contraindicated working with computers women who were pregnant and lactating women;
leave your computer on for more than two hours;
not work for a half-hour, the keyboard;
change the nature of work during the day;
use every opportunity to go up and razminatsya during the day;
to start down the long work;
If stynut hands Wear light gloves;
at the first sign of discomfort immediately go to a doctor;
Follow ergonomic workstation.
keep working and recreation;
allow correct working position.

Properly organizing work at the computer can accurately determine whether there is another conflict, masked by health care.

If we get another hidden conflict is a good sign for the conflict and its causes. In some cases it is very difficult to admit people who live close to you. This is fertile ground for the resolution of other conflicts since, in fact, have a negative review "logjam" between family members.

Two cups of green tea and one orange a day to protect against computer radiation

Two cups of green tea and orange one day provide reliable protection from radiation emanating from the screens of personal computers, Chinese media reported with reference to the research of Chinese scientists.

Thus, green tea leaves contain, in addition to other useful substances elements opposing the destructive effects of radiation.

The oranges, according to the Chinese scientists, contains substances that prevent the emergence and growth of tumors and improve immunity. Moreover, the oranges in vitamin A and carotene strengthen the protective functions of the skin.

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

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

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

 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

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

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?

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.
