A wrist splint is a brace that looks like a fingerless glove. It stabilizes the wrist in a straight and sometimes slightly bent-back position. A wrist splint can be worn to support the wrist while holding it firm and still (immobilizing it).
A good wrist splint should:
Be comfortable, washable, durable, and easy to remove.
Keep the wrist in a neutral position. The wrist is generally in a neutral position when the person is holding a glass of water, with the thumb in line with the forearm.
Restrict wrist movements while allowing fine hand movements, such as writing or typing.
Splints are available without a prescription from a drugstore or with a prescription from an orthopedic or medical supply house. Physical and occupational therapists can custom-fit splints made from lightweight materials. Health professionals usually do not recommend long-term use of splints (more than 72 hours) because the muscles in the hand or wrist can become weak.
