Question: Can Computer Use Cause Carpal Tunnel Syndrome?
A Mayo Clinic study found that heavy computer use (up to 7 hours a day) did not
increase a person's risk of developing carpal tunnel syndrome.
There is little clinical data to prove whether repetitive and forceful movements of the hand
during work or leisure activities can cause carpal tunnel syndrome. Repeated motions performed in the course of normal work or other daily activities can result in repetitive motion disorders such as bursitis
Writer's cramp - a condition in which a lack of fine motor skill coordination and ache and pressure in the fingers, wrist, or forearm is brought on by repetitive activity - is not a symptom of carpal tunnel syndrome.
