Although supine stepping can generate lower-limb joint trajectories which are close to normal gait, the inter-segmental dynamics of supine stepping are believed to be different from those of upright walking. Furthermore, training in a supine position requires a certain loading on the foot to mimic the ground reaction forces, where different loading amplitudes influence the joint dynamics. This work analysed the kinetics of supine stepping with variable loading and investigated structural modifications for the Gait Orthosis for Early Rehabilitation system to address this kinetic difference. Three able-bodied subjects walked overground while their walking performance was recorded. Based on the experimental data, a leg-linkage model was developed to simulate the dynamics of upright walking. Th...
