Samenvatting
The aim of this study was to determine the subtalar joint dynamic behaviour in inversion-eversion. A purpose-built test rig was developed to impose the foot rotation along the xversion axis. Six inversion tests and six eversion tests were performed on six pairs of human cadaver legs. Accelerations, angular velocities, forces and moments were measured on the forefoot, calcaneus and leg in order to assess the force balance acting at the subtalar joint. The fibula contribution and the relative motion between the forefoot and the calcaneus were determined. The subtalar joint moment was evaluated with respect to the xversion angle of the forefoot and of the calcaneus. (A)
