ABSTRACT
Loss of a limb is a traumatic and life-altering event. For many amputees, recovery and rehabilitation after limb loss include the use of a prosthetic limb to replace the lost extremity. In the case of a lower-extremity amputation such as a transtibial, or belowknee (BK) amputation, the prosthesis typically includes a socket, pylon, and prosthetic foot. The design of the prosthetic foot is critical because it functionally replaces the intact foot-ankle complex. This sophisticated collection of bones, tendons, ligaments, and muscles supports the body’s weight, accommodates the ground surface, and propels the body forward.
