What kind of orthosis is typically used for the treatment of carpal tunnel syndrome?

A cock-up splint is commonly used for the treatment of carpal tunnel syndrome because it positions the wrist in a neutral or slightly extended position, which alleviates pressure on the median nerve. This type of orthosis helps to limit wrist flexion, a position that can exacerbate symptoms of carpal tunnel syndrome, such as pain, numbness, and tingling in the hand and fingers. The cock-up splint is designed to provide support and stability to the wrist while allowing the fingers some mobility, facilitating function while protecting the wrist from movements that could worsen the condition.

In comparison, volumetric orthoses are generally not specifically targeting the symptoms of carpal tunnel syndrome but rather serve broader purposes such as measuring or managing limb volume changes. A wrist extension orthosis might provide support but may not adequately prevent movement that compresses the median nerve. A dorsal blocking splint is more appropriate for post-surgical rehabilitation scenarios and may not be directly suited for the conservative management of carpal tunnel syndrome. Overall, the design and function of a cock-up splint make it the most effective choice for addressing the symptoms associated with carpal tunnel syndrome.
