Mouse hand is the scientific name for carpal tunnel syndrome, a peripheral nerve entrapment syndrome caused by the compression of the median nerve in the carpal tunnel. The "median nerve", which is responsible for the sensation in the fingers, is compressed while conducting some nerve tendon tunnels in the wrist.

The main symptoms are pain in the front of the wrist and numbness in the hand, tingling or swelling in the thumb, index finger and middle finger, and reduced grip strength. Severe cases of mouse hand can lead to discomfort throughout the upper limbs, especially soreness in the shoulders and neck.

Who is most likely to be affected
Office workers who use computers for long periods of time, housewives, technical workers, drivers and the elderly are very susceptible to mouse-handedness due to work strain or physical decline.
