Repetitive strain injury

Repetitive strain injury (RSI), also known as occupational overuse syndrome, is a medical condition. It causes pain in the muscles, nerves, or tendons after a person uses the same part of the body over and over again, or without taking breaks. It is usually caused by doing the same thing repeatedly or without breaks. Using a computer for long periods of time is a common cause of this problem.

Repetitive strain injury is described as a sudden, intense pain in affected parts of the body, often the wrists, neck, back or hands, that keeps coming back. It is different from more specific diagnoses, because there are many possible causes for RSI. The pain is often spread across different muscle groups and inspection of the affected area usually cannot show any differences from that of a healthy person. Because of this, treatment for RSI is usually limited to rest and exercises, and sometimes wearing a brace.

Treatment for Repetitive strain injury

This is often the first recommendation. Moving the affected area is important, but avoid stressing the joint. In conservation, this is often not practical without taking time-off from work. Too much inactivity can cause atrophy of muscles and increase the severity of the disorder.
Stretching Routines are implemented to help reduce hypertonic muscles and increase their flexibility and dexterity.
Splinting and Analgesics may help "mask" symptoms for a while, but unless the "real" cause of dysfunction is eliminated, the symptoms come right back. The long-term success rate of Splints and Anti-Inflammatory Medications is extremely low.
Wrist Braces and Splints are not effective in treating carpal tunnel syndrome and repetitive strain injuries, but can assist if worn during nighttime only. These devices are meant to keep the wrist from dropping into flexion so that the wrist stays in the straight, neutral position in order to reduce impingement of the carpal tunnel. But instead, wrist braces often increase the symptoms of carpal tunnel syndrome and repetitive strain injuries, especially if worn during the daytime.

Do not allow a complete range of motion of the fingers, wrist and elbow joints from flexion into full extension, and full abduction (splaying) of the fingers, which is absolutely critical in effectively rehabilitating carpal tunnel syndrome and repetitive strain injuries. 
Provide finger extension of only 1-5 of the digits, and with most of the emphasis on the Metaphalangeal joint (most proximal finger joint). This means that there is only one joint being exercised, while the others stay stiff and are only affected by isometric, (non-moving) exercises. 
Provide only wrist extension without finger extension and finger abduction!
Do not include finger, wrist and elbow extension, along with full abduction (splaying) of the fingers, all in one exercise motion, without any type of gripping or squeezing action required.
