movement at the ankle joint that points the foot downwards away from the leg, or movement of the toes that curls them down towards the sole (compare dorsiflexion). Figure 1.

Further, this movement adaptation could be due to simultaneous ipsilateral trunk flexion toward the amputated limb [47] and inability to plantarflex the prosthetic ankle [6].

Motor block was assessed by asking the patient to plantarflex and dorsiflex the foot and was classified as follows: 0=normal movement, 1=decreased movement, 2=no movement.
Inability to flex the hip joint, extend the knee joint and dorsiflex or plantarflex the foot was taken to indicate successful motor blockade.
This effect may also translate to seated positions where the ankle is free to plantarflex to accommodate the surface under low loads, though this was not mentioned by the subject.
Muscles innervated by the SF nerve (fibularis/peroneus longus and fibularis/peroneus brevis) evert and weakly plantarflex the foot and can counter the actions of tibialis anterior.
Prosthetic ankle units may be fitted on individuals to improve stability during level walking by allowing the prosthetic foot to plantarflex during early stance phase and enable the plantar surface of the foot to contact the ground sooner, which has been hypothesized to improve stability [25].
