Abstract: An inflatable hand orthosis promotes a functional positioning of the fingers and thumb. An inflatable air bladder is formed by two vinyl sheets bonded together and inflated and deflated by a pump bulb and deflation valve, respectively, which are fixed to the vinyl sheets and communicatingly interconnected with the air bladder. The bladder is sewn into a soft cloth covering in order to form a wearable device which may be used either alone or in conjunction with hand, wrist, and finger orthosis. The hand device is placed on the palm and under the patient's fingers while deflated. Then the bladder is inflated to align and extend the fingers and to abduct the thumb.

Abstract: A dynamic brace joint for use in orthotic devices which adjustably restrains and limits the flexion and extension range of a limb joint while promoting and assisting joint extension or flexion using a continuously applied, adjustable, dynamic force. The dynamic brace joint includes an upper brace support member and a lower brace support member, which are pivotally interconnected at their proximal ends. The joint may be incrementally adjusted to provide a range of pivotal motion between the interconnected upper and lower members. A tensioning, elastic, or resilient member exerts a continuously applied adjustable dynamic force on the interconnected upper and lower members. The terminal end of the brace support members may be incorporated into a splint or brace to accommodate limb parts associated with the limb joint.
