Abstract		The significance of electrically stimulated ankle plantarflexors during functional-electrical-stimulation-assisted walking was evaluated. The dynamic (floor reaction forces) and kinematic (ankle and hip joint trajectories) data were assessed in incomplete spinal cord injury patients. The interplay of kinematic and dynamic parameters was described by mathematical modelling. An improved hand-control module providing voluntary control over functional-electrical-stimulation-restored walking pattern was developed. A specially designed two-step hand push-button enabled the division of the stride time into three distinct phases: midstance, push-off, and swing phase. Noticeable effects of functional electrical stimulation during the push-off phase were particularly evident in the vertical ground reaction force and horizontal hip joint displacement.
