Wearing a wrist brace for carpal tunnel syndrome is useful. Carpal tunnel syndrome is a condition that causes numbness, tingling or burning pain in the fingers, weakness and other symptoms due to compression of the median nerve in the carpal tunnel. It is usually caused by trauma to the wrist, such as distal radius fracture, carpal bone fracture, wrist contusion, etc., or by tendon sheath cysts or lipomas in the carpal tunnel. With these conditions, the lumen of the carpal tunnel is reduced and the pressure in the lumen increases, compressing the median nerve and carpal tunnel syndrome occurs. Wearing a wrist brace can limit the movement of the wrist, which can improve the compression of the median nerve and help to relieve pain and swelling. Suffering from carpal tunnel syndrome, it is recommended to carry out standardized treatment under the guidance of a doctor, and not to deal with it blindly on your own, so as not to delay the condition.
