Repetitive Strain Injury

A repetitive strain injury (RSI), also called CTD(CTD), occupational overuse syndrome, or work related upper limb disorder (WRULD), is any of a loose group of conditions resulting from overuse of a tool, such as a computer keyboard or musical instrument or other activity that requires repeated movements. It is a syndrome that affects muscles, tendons and nerves in the hands, arms and upper back. The medically accepted condition in which it occurs is when muscles in these areas are kept tense for very long periods of time, due to poor posture and/or repetitive motions.

It is most common among assembly line workers, computer workers, store checkout clerks, and professional musicians. Good posture, ergonomics and limiting time in stressful working conditions can help prevent or halt the progress of the disorder. Stretches, strengthening exercises, and biofeedback training to reduce neck and shoulder muscle tension can help heal existing disorders.

The most well known injury is Carpal tunnel syndrome, which is common among guitarists as well as assembly line workers but relatively rare among computer users: computer-related arm pain is generally caused by another specific condition.[citation needed] Many of these disorders are interrelated, so a typical suffering person may have many of these at once. For other people, no specific diagnosis is possible. In these cases it is often best to treat RSI as a single general disorder, targeting all major areas of the arms and upper back in the course of treatment.
