While the motor output associated with human walking is thought to be largely generated by spinal centers, both supraspinal and afferent input contribute considerably to the locomotor output.3 Considerable evidence derived from both animal and human experiments suggests that specific afferent input to the spinal cord such as hip proprioceptors, Group-I muscle afferents and plantar cutaneous afferents play a significant role in modulating reflex transmission during walking and standing.
