What is Repetitive Strain Injury (RSI) ?

Repetitive strain injury (RSI), sometimes known as repetitive stress injury, is a group of conditions caused by the overuse of computer keyboards and mice, guitars, knives etc.

It is an overuse syndrome affecting muscles, tendons and nerves in the arms and upper back. Because of this it is also classed as an upper limb disorder. According to doctors it occurs when muscles in these areas are kept tense for very long periods of time, due to poor posture and/or repetitive motions.

RSI is occasionally known as cumulative trauma disorder or occupational overuse syndrome as well.

It is most common among people who work on assembly lines or at computers for long periods of time. You can help prevent or slow the progress of the condition through good posture, ergonomics and taking regular breaks from work.

Stretches, hand strengthening exercises and massages can reduce neck and shoulder muscle tension can help heal existing disorders.
