Repetitive Strain Injury or RSI describes a group of conditions associated with overuse of soft tissues such as muscles, tendons and nerves. RSI causing pain can affect the upper back, arms, hands, wrists, or fingers. Continuous and prolonged use of a computer keyboard, strumming a guitar, or wielding tools on an assembly line, have all been associated with RSI.
