none6Kinematic models based on one-degree-of-freedom equivalent spatial mechanisms replicated well natural motion of the knee and ankle joints by direct representations of their anatomical structures. However, these mechanisms are limited by high computational costs, overall mechanical complexity and numerical instability. Spherical parallel mechanisms based both on anatomy and kinematics are here analysed to overcome these problems. These models include isometric fibres within two ligaments (the cruciates for the knee, the calcaneal-fibular and tibio-calcaneal for the ankle) and a spherical pair at the pivot point of the nearly-spherical motion observed for these joints. Spherical mechanisms were defined from experimental data obtained fro...
