摘要：
Gentle and substantially linear vertical motion of a wheelchair foot support is expected to assist lower limb circulation for a user with limited leg mobility, reducing risks of clotting or blockage within peripheral blood vessels. Additionally, to whatever extent limb atrophy may be reduced by imposed motion, motion of the foot support may help in maintaining muscle mass and flexibility of ligaments. Accordingly, a circulation assisting wheelchair includes a foot support movably connected to the wheelchair frame by a movable foot support assembly. The movable foot support assembly is connected to a rear wheel of the wheelchair via a drive train, so that normal operation of the wheelchair drives substantially linear vertical oscillating motion of the foot support.
