29 16. I've heard many names for keyboard injuries. What do they all mean?

A. Repetitive Strain Injury (RSI) is a description of an injury associated
any repetitive activity such as hammering, piano playing, truck driving,
computer use, or even shaking hands. Occupational Overuse Syndrome (OOS),
Cumulative Trauma Disorder (CTD), and Work Related Upper Limb Disorders
(WRULD), are all equivalent expressions to RSI.

Tendonitis and tenosynovitis are characterized by inflammation of tendo ns
or their surrounding sheaths, respectively. Both of these RSI disorders
usually begin as mildly aggravating and, given bad habits, may quickly
progress to be severely debilitating. These common RSI injuries also add
to he difficulty of proper diagnosis and deserve greater recognition.
These endon inflammations usually occur before full blown Carpal Tunnel
Syndrome.

Carpal Tunnel Syndrome (CTS) is a specific, severe, and debilitating form
of RSI which describes a squeezing of the median nerve as it runs to hand.
The nerve is squeezed by swollen tendons surrounding it as they cross
hrough a tunnel made by ligaments at the inside of the wrist.

The National Center for Health Statistics estimates at least 1.89 milli on
people have Carpal Tunnel Syndrome. Many experts feel that CTS is also
associated with nerve compression symptoms in the chest or shoulders.
**All RSI symptoms should receive immediate medical attention from
physicians experienced in RSI.**
