Can you tell me more about hand splints for cts or sore hand, wrist?

Cts splint. For carpal tunnel a cock-up wrist splint is used to maximally open up the canal and limit pressure on the nerve. It is primarily used at night to control nocturnal parasthesias, the pain and numbness that awakens you at night. It does this by preventing you from sleeping in a flexed position at the wrist. Splints are often used for different types of tendonitis to limit use of the inflamed tendon.
