Seven different suspension systems for below-knee prostheses were tested on 20 adult, unilateral amputees . All subjects walked with a prosthesis . Gait was evaluated with regard to longitudinal and vertical accelerations of the body, forward velocity, axial (piston) movement of amputated limb in the socket, and knee movement . Harmonic analyses of variable waveforms provided the primary method to discriminate performances among the suspensions . The appropriateness of a given suspension system
