How can Repititive Strain Injury affect a person using the computer?

Repetitive strain injuries occur when tendons move through lubricated sheaths called bursae (the sheaths go by a variety of other names as well - see http://www.forensic-applications.com/cts/cts.html ). If the tendon moves through the bursae in such a manner as to cause inflammation, then the cross section of the bursa becomes smaller which then creates more friction which exacerbates the problem in a positive feedback loop. Preventing the inflammation in the first place is much more effective than breaking the cycle. Prevention is effected by observing good ergonomic principles. "Ergonomics" means fitting the workplace to the person - ergonomics is NOT applying the use of "ergonomic" apparel or prophylactics such as wrist splints, and wrist rests. The use of the products are usually "anti-ergonomic" and can often create a problem, or exacerbate an existing problem. In the case of the computer work station, the station should be adjusted specifically for the person in question, the angle of the screen, the height, and pitch for the chair, the location of the keyboard, the length of time typing between breaks, and even the temperature of the work environment are all legitimate ergonomic considerations. For an example of an ergonomic evaluation see of a computer work station see: http://forensic-applications.com/index_files/anne.jpg Repetitive stress syndrome injuries can result in permanent loss of the limb.
