ABSTRACT:
Gentle and substantially linear vertical motion of a wheelchair foot support is expected to provide superior results for maintenance of a wheelchair user's leg muscle mass' thus reducing atrophy of the wheelchair user's legs. Additionally, gentle continuous motion of the foot support is expected to aid in maintaining elasticity of the wheelchair user's leg joint ligaments' thus reducing contractures. Accordingly, an atrophy-reducing wheelchair includes a movable foot support mounted to a linkage that is movably connected to the wheelchair frame. As the wheelchair moves in normal operation, rotation of a wheelchair wheel drives the linkage to provide substantially linear vertical reciprocation of the foot support.
