Abstract :
A kinetic, biomechanical model of the foot and ankle during the stance phase of gait was developed based on a previously described four-segment kinematic model. Moments were calculated at the first metatarsophalangeal (1MTP), talonavicular (TV), subtalar (SUBT) and talocrural (ANKL) joints. The 1MTP, SUBT and ANKL were modelled as revolute joints while the TV was modelled as a ball-and-socket. Eight subjects were tested and their computed moments were normalized and averaged. Range of average moments were: 1MTP (-0.03 to 0.53), TVx (-0.15 to 3.30), TVy (-0.15 to 4.24), TVz (-1.83 to 0.47), SUBT (-0.43 to 3.89) and -1.00 to 7.26 at ANKL
