Placement of the neuroprosthesis (single leg setup) on one of the participants (left image) and the schematic placement of stimulation electrodes and sensors (right image). The neuroprosthesis supports the stimulation of four muscle groups (quadriceps, hamstrings, tibialis anterior and gastrocnemius) to control the knee and foot motion during gait. The control of each leg is independent, and therefore the double leg setup is a duplication of the single leg setup. Due to the limitations of the wireless sensors, the single leg setup was used in this work
