A wrist splint is a brace that looks like a fingerless glove and that 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.

Consider the following guidelines when using a wrist splint:

• When worn to stabilize the wrist during sleep, a wrist splint can reduce pain and pressure on the median nerve.
• A wrist splint is not a substitute for good workplace design and proper body mechanics. Some experts advise against wearing a wrist splint while working, because doing so can strain the hand's tendons.
• A wrist splint is a helpful short-term treatment for carpal tunnel syndrome. However, long-term use can cause your muscles to weaken. During and after a period of splint use, exercising and slowly increasing hand and wrist movements will help prevent your wrist muscles from weakening.

Splints are available in drugstores without a prescription. They are also available by prescription from orthopedic and medical supply stores. Physical and occupational therapists can make custom-fit splints from lightweight materials that may be more comfortable to wear.
