Fig. 2: Motor Point identification in thigh and calf muscles.

Mapping of motor points and positioning of electrodes. A Motor points over thigh muscles (rectus femoris, vastus medialis and vastus lateralis) that allowed extension of the leg. B Positioning of superficial electrodes for FES-IP phase. C Motor points over calf muscles (gastrocnemius and soleus) to allow shifting of weight to the front of the foot.
