Many people with mild to moderate carpal tunnel syndrome wear a splint at night for a few weeks. The splint holds the joint in a neutral position. The symptoms are worse at night because your hand is more likely to bend while you're sleeping. 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.
Splint should be wore over the back of the arm. The metal insert should run along the inside of the arm onto the palm of the hand. The splint should not restrict any finger movements. Splints can be washed in warm water, but the metal bar should be removed.
