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.
Think about these guidelines when you use 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 isn't 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. But long-term use can cause your muscles to weaken. During and after a period of splint use, exercise and slowly increase your hand and wrist movements. This will help prevent your wrist muscles from weakening.
Splints are available in pharmacies 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.
