If you’re dealing with this condition, you need a wrist brace that relieves pressure on the median nerve to ease symptoms of carpal tunnel syndrome. The nerve passing through the carpal tunnel gets inflamed due to overuse and/or poor posture while typing, etc, or other causes. Wearing a night splint with support both along the palm as well as above the wrist, takes the pressure off the nerve, allowing it to heal, and reducing pain, numbness and tingling. (In severe cases, some support during the day may be warranted, but one that allows for some movement, to manage day to day function).
