A wrist splint is a garment that is worn around the wrist to protect it during strong use or for allowing it to heal. Wrist splints are common accessories in injury rehabilitation processes affecting the wrist. They immobilize the joint and provide heat and compression to the wrist bones and ligaments. A wrist splint is a brace that looks like a fingerless glove. It stabilizes your wrist in a straight and sometimes slightly bent-back position. Wearing a wrist splint minimizes pressure on the median nerve and allows you a period of "relative rest" from movements that make carpal tunnel syndrome worse.
