Computers Today Computers are a big part of todays society. Nearly every business and industry uses some type of computer system. Even though computers offer many advantages there’s always a down side.
Carpal Tunnel Syndrome Carpal tunnel syndrome is pressure on the median nerve -- the nerve in the wrist that supplies feeling and movement to parts of the hand. Carpal tunnel syndrome is common in people who perform repetitive motions of the hand and wrist. Typing on a computer keyboard is probably the most common cause of carpal tunnel. The condition occurs most often in people 30 to 60 years old, and is more common in women than men.
Symptoms •Numbness or tingling in the thumb and next two or three fingers of one or both hands •Pain extending to the elbow •Pain in wrist or hand in one or both hands •Problems with fine finger movements (coordination) in one or both hands •Weak grip or difficulty carrying bags •Wasting away of the muscle under the thumb (in advanced or long-term cases)
Treatments One way to treat carpal tunnel is to wear a splint or brace. A more drastic way would be to undergo carpal tunnel release. Carpal tunnel release is a surgical procedure that cuts into the ligament that is pressing on the nerve. Surgery is successful most of the time, but it depends on how long the nerve compression has been occurring and its severity.
CVS (not the drugstore) Computer Vision Syndrome is the name for eye problems caused by computer usage. CVS is not one specific eye problem, the term encompasses a whole range of eyestrain and pain experienced by computer users. 50% and 90% of people who work at a computer screen have at least some symptoms of eye trouble.
Causes Computer vision syndrome is similar to carpal tunnel syndrome and other repetitive stress injuries. It can occur if you carry out the same motion over and over again. Like other repetitive stress injuries,computer vision syndrome can get worsethe longer you continue the activity.
SymptomsYou may have CVS if you have Blurred vision Double vision Dry, red eyes Eye irritation Headaches Neck or back pain
No Cure? Working on a computer is more challenging to your eyes than reading a book or piece of paper, because a computer screen also adds the elements of screen contrast, flicker, and glare. The problem for most people with CVS or carpal tunnel is that they make a living doing the very thing that causes their health problems. Some computers like the HP TouchSmart PC don’t have a keyboard or mouse, the monitor is touch screen. This could solve carpal tunnel for computer workers. Maybe computer designers will find a way to prevent CVS too.
