Wrist Cock-Up Splint: which statement describes its purpose?

A wrist cock-up splint is used to hold the wrist in a slight extended position while keeping the hand and fingers available for function. This helps maintain the natural arches of the hand and allows full thumb movement and full MP joint flexion, which supports a functional grasp and hand use without forcing the fingers to stay rigid. That’s why the description involving dorsal or volar immobilization that preserves the hand arches, thumb movement, and MP flexion best fits. The other ideas don’t match typical goals of this splint: immobilizing the elbow to protect the shoulder shifts focus away from the wrist; promoting wrist flexion contradicts the extension position; and restricting motion to a fixed extended position ignores the need for finger and thumb mobility.
