The term repetitive strain injury (RSI) is used to describe a range of painful conditions of the muscles, tendons and other soft tissues. It is mainly caused by repetitive use of part of the body. It is usually related to a task or occupation but leisure activities can also be a cause. Unlike a normal strain following a sudden injury, symptoms of RSI can persist well beyond the period of time it would take symptoms of a normal strain to ease.
