Pain, usually in a limb, felt by someone who performs the same movement many times over a period, e.g. when operating a computer terminal or playing a musical instrument.
An injury that occurs when repeated movements of one part of the body damage the tendons, nerves, muscles, and other soft tissues. The muscles and tendons in the arms are most commonly affected by the condition. People who engage daily in jobs requiring repetitive movements of the fingers, hands, arms, and shoulders are particularly vulnerable to RSI. Those jobs include typing on a keyboard, using a computer mouse, playing a musical instrument, and working on an assembly line. Carpal tunnel syndrome, tendinitis, tenosynovitis, and certain other disorders that cause muscle and tendon pain are sometimes included in the classification of repetitive strain injuries.
A type of overuse injury that impacts individuals engaged in prolonged repetitive actions, like keyboard users and musicians, leading to discomfort and diminished strength in the wrists, fingers, or arms. This condition, known as Repetitive Strain Injury (RSI), can progress to a chronic state, characterized by persistent pain even after discontinuing the activity responsible for its onset.
