Abstract

Recent studies proved that the ankle unloaded motion is nearly spherical and can be accurately modeled by one degree-of-freedom spatial spherical mechanisms. Starting from relevant experimental data measured on nine specimens, the global optimal pivot-point (PP) position, i.e., the center of this spherical motion, is obtained in this study and the effect on ankle motion of the changing position of this PP is analyzed.
