An enhanced prosthesis for through ankle joint amputation by strengthening the ankle joint with dorsal and plantar flexion movements

Abstract Amputees pursue to obtain an artificial limb that suits them and adapts as close as possible to their healthy limb, especially for amputees of the lower limbs that are characterized by the necessity of performing the function of walking through the existing joints to make the amputee feel like having a healthy limb and perform its own needs. Here in this research we will address the improvement of the prosthetic limb of the amputee through the ankle joint, as a movable ankle joint was designed for the level of amputation through the ankle joint in the SolidWorks program and the data was analyzed using ANSYS to find out the extent to which the joint is able to perform plantar flexion and dorsal flexion movements and its range of motion by applying them realistically through tests conducted on the amputee when wearing the prosthetic with the hinged ankle joint and simile it with the conventional prosthetic with the fixed joint.
