RSI (Repetitive Strain Injury)

Every computer user, please be aware of RSI. RSI stands for Repetitive Strain Injury, which a person can have because of inappropriate sitting or standing positions.

A repetitive strain injury (RSI), also called cumulative trauma disorder (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, eg. computer, guitar or knife, 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.

People who have RSI cannot be cured but a suggestion is raised to get away from this. That is to say, try to sit or stand or do something appropriately. Try to exercise. Bend and lean your arms, hands, legs and back against a wall.

It is most common among assembly line and computer workers. Good posture, ergonomics and limiting time in stressful working conditions can help prevent or halt the progress of the disorder. It is also a problem for guitarists who play with very tensed muscles.[citation needed] Stretches, strengthening exercises, and biofeedback training to reduce neck and shoulder muscle tension can help heal existing disorders.
