ABSTRACT:
An ankle-foot orthosis made of thin-sheeted polypropylene material which comprises a foot section and a leg section articulately attached to one another on each side of the ankle in order to facilitate dorsi-flexion. The leg section has a flanged lower lip overlapping the upper edge of the foot section. The overlap provides a stop for the backward movement of the leg section around the articulation point, thus limiting plantar flecion and foot drop.
