ABSTRACT:
The same orthosis can be sequentially used to bend different wrists. The orthosis may be used to bend a first wrist in flexion and a second wrist in extension. When the orthosis is to be used to bend a wrist in flexion, a pair of cuffs and cuff arms are connected with a forearm and hand with the orthosis in a first orientation relative to the wrist. At this time, the cuff arms and an actuator mechanism are disposed in an inner sector disposed adjacent to a palm side of the hand. When the orthosis is to be used to bend the wrist in extension, the orthosis is mounted on the forearm and hand in a second orientation with the cuff arms and actuator mechanism in an outer sector adjacent to the back side of the hand. During operation of the orthosis, force is transmitted from an input member through an actuator mechanism to the cuff arms to pivot the cuff arms about spaced apart parallel axes. At the same time, force is transmitted from the actuator mechanism to the cuffs to move the cuffs along the cuff arms in a direction toward the wrist and axes about which the cuff arms are pivoted.
