  • Publication number: 20150265424
    Abstract: A prosthetic foot comprises a ground engaging bottom resilient member, a resilient heel member, and a resilient toe member that collectively circumscribe an open volumetric space. The members resilient compress to absorb compressive force throughout the entire stride of an individual utilizing the foot. The prosthetic foot stores energy during a heel strike phase of a gait cycle, and releases energy during a toe-off phase of the gait cycle in order to assist forward movement of a user. During the gait cycle, a loading response during the heel strike phase compresses the heel member and the toe member, and causes a deflection of the rear portion of the bottom member. Furthermore, an upward deflection of at least one of the bottom member and the toe member stores energy during the transition from the heel strike phase to the toe-off phase of the gait cycle.
