The origin of these difficulties is the inability of the prosthetic replacement to duplicate normal leg functions. As a result, other body segments must adjust to compensate for the prosthetic segment in order to attain dynamic stability and similar function. These adjustments away from normal lead to locomotion patterns which significantly affect the amputee's mobility. The normal human locomotor system is an extremely flexible, dependable, and controllable system. e. ) to transport himself from one location to another.

SIMULATION RESULTS Based on the results of the digital simula­ tion studies, the following parameters were chosen for the actuator design. Moment Arm The effects of the attachment point of the cylinder along the shank produce no signifi­ cant change in the effective moment arm at the knee of the actuating assembly.

G. May, 1971; Radcliffe, 1973) by Mk = I (0h-0k) + m Xk h cos(Oh-Ok) + (m Yk + Ws) h sin(Oh-Ok) . (12) where m and I are the mass and moment of in­ ertia of the shank, respectively, and the joint angles Oh and 0k are as shown in Fig. 4. In this development the leg is represent­ ed as a compound pendulum consisting of two links connected at a frictionless pivot. Mo­ tion of the pendulum is assumed to be con­ strained to the sagittal plane. In block 4 (Fig. 3), given hip displacements, and knee moment (Mk), eq.
