Repetitive strain injury (RSI) refers to symptoms caused by prolonged repetitive movements of one part of the body, as may occur during long sessions using a computer keyboard, for example.
RSI mainly affects the neck, shoulder, arms, and hands. Symptoms may include pain, tingling, throbbing, stiffness, weakness, and cramp in the affected area.
Treatment may include pain relievers, physical therapy, and wearing a support on the affected area.
Modifying the activity that causes symptoms is also important; if RSI is job-related, the employer should be informed.
