What is a repetitive stress injury (RSI)?
Repetitive stress injuries, also known as repetitive strain injuries, repetitive motion injuries, and cumulative trauma disorders, are caused by unhealthy motions that are repeated with frequency. RSI symptoms may manifest themselves anywhere from the fingertips to the shoulder, neck and back area and include one or more of the following: muscle fatigue or weakness, feelings of tightness, swelling, temporary tingling or numbness, nocturnal numbness, intermittent or chronic pain, loss of grip strength, inability to pick up small objects, and a general sensation of discomfort and loss of motor freedom. Carpal Tunnel Syndrome, Tendonitis, Dystonia, Tennis Elbow, Trigger Finger/Thumb, and BlackBerry Thumb are some of the better known types of RSI.
