چکیده:

In this paper after a brief review on previous studies on above knee prosthesis design, SEP prosthesis which has recently introduced considered. This prosthesis has modeled with fixed and moving ankle separately during the swing phase of walking and the optimized physical parameters have been discussed. Here it is tried to compare the results of these models and survey the effects of the improvement of segmentation in behavior and the resulted optimized parameters of the models. The comparison of models in the amount and the pattern of actuation torque, damping torque and inertial effects represent that, this improvement in segmentation results in reduction in the amount of all of the considered physical parameters which is appreciated.
