Get StartedSplinting for carpal tunnel syndrome
By Mayo Clinic staffSplints (braces) are the most commonly used nonsurgical treatment for carpal tunnel syndrome. Splints that immobilize the wrist in a neutral (unbent) position are most likely to relieve discomfort. An unbent wrist maximizes the size of the carpal tunnel, which reduces pressure on the median nerve, relieving your symptoms.
You can buy ready-made splints at a medical-supplies store. Or you can ask your doctor to prescribe custom-made splints. Both are equally effective, although many people find custom-made splints more comfortable to wear. In either case, you may find splints make certain hand movements difficult to do.
You may need to wear a splint for a few weeks before noticing definite improvement. Some studies show that continuous splinting — wearing a splint both day and night — is more effective than wearing a splint just at night. Others, however, show little or no added benefit from 24-hour splinting. Many people find that a splint restricts their hand and wrist movements too much to be worthwhile at work and around the house, so night wear alone is a good option.
Splints are safe and relatively inexpensive, and they give many people with carpal tunnel syndrome excellent short-term relief from their symptoms. Besides relieving discomfort, splints can sometimes improve conduction of nerve impulses along the median nerve, which can improve strength, dexterity and sensation.
Splints are most likely to work for you if you've had mild to moderate carpal tunnel syndrome symptoms for one year or less. Splints may be a good choice for pregnant women if water retention is causing temporary carpal tunnel syndrome symptoms.
