Repetitive strain injury (RSI) is a general term for pain in muscles, nerves and tendons caused by repetitive movement and overuse, such as typing, using a mouse or assembly work.
Carpal tunnel syndrome is when a nerve in the wrist is squeezed, causing tingling, numbness or pain in the hand and fingers. Both can often be improved with changes to activity, posture and treatment.
Physiotherapists can advise on exercises, workstation set-up and splinting. Massage and soft tissue therapy can relieve tight forearm, neck and shoulder muscles that may contribute, and posture-based approaches such as the Alexander Technique can help reduce strain.
