Alpha Medical Elastic Wrist Support Brace; Side-Closure Cock-Up Support Wrist Split Brace. L3908 The Side-Closure Elastic Cock-Up Wrist Split is made with a soft cotton/elastic material that provides gentle compression to the wrist, while the palm stay provides immobilizing support. Four Hook & Loop closures secure the wrist splint at the back of the hand and wrist for a comfortable and secure fit. The support cuts low across the palm to allow full range of the fingers and hands while helping to reduce irritation and pressure points. The palmer splint is bent at the recommended 30° angle, which is believed to help open the carpal tunnel and therefore help remove pressure on the carpal nerve. The elastic provides soothing compression which can help to reduce swelling and can help to soothe arthritis and sore wrists. Cock-up wrist splints are recommended by health care professionals for carpal tunnel syndrome, arthritis, wrist sprains, post-casting, postoperative, protection during activity, wrist instability, and support for sore wrists and thumbs.
