Repetitive Stress Injury (RSI), is also known as muscular-skeletal disorder (MSD), Cumulative Trauma Disorder (CTD), occupational overuse syndrome, non-specific arm pain, and or work related upper limb disorder (WRULD). The term “repetitive stress injury” is most commonly used to refer to patients in whom there is no discrete, objective, path physiology that corresponds with the pain complaints. It may also be used as an umbrella term incorporating other discrete diagnoses that have (mostly unfairly) been associated with activity related arm pain such as Carpal tunnel syndrome, Cubital tunnel syndrome, a form of Ulnar nerve entrapment, true Thoracic Outlet syndrome, DeQuervains syndrome, Stenosing tenosynovitis/trigger finger/thumb, Intersection syndrome, Golfer’s elbow (medical epicondylosis), Tennis elbow (lateral epicondylosis), or Focal dystonia. Arm use is speculative etiological factor for these diagnosis that remains unproved and debatable.

For example, the association of carpal tunnel syndrome with arm use is disproportionately commonplace given that it is not well-established. It is important not to confuse carpal tunnel syndrome (which causes numbness) with activity-related arm pains. Typing has long been stigmatized as a cause of carpal tunnel syndrome, but recent evidence suggest that, if anything, typing may be protective.#

Repetitive stress injuries (RSIs) are conditions caused by placing too much stress on a joint, and they vary in type and severity. Most RSIs are linked to the stress of repetitive motions at the computer or overuse injuries in sports. RSI in kids may occur from heavy computer or video game use, playing musical instruments, or the repetitive motion of sports like tennis.

An RSI occurs when stress is placed on a joint, pulling on the tendons and muscles around the joint. When the stress occurs repeatedly, the body does not have time to recover and becomes irritated. The body reacts to the irritation by increasing the amount...
