RSI, or Repetitive Strain Injury, is an illness caused by frequent or intensive use of a particular body part or action that causes stress to the muscles and tendons. RSIs are quite common amongst office workers who use computers extensively and the elderly who do repetitive motions of the same strain on the body over time. Typical symptoms of RSI include pain, tingling, numbness and a general feeling of weakness in the affected hand, wrist or arm. If left untreated, the disorder can worsen and lead to severe problems such as carpal tunnel syndrome.
