Neuromechanical Function of Reflexes During Locomotion

Reflex responses arising from various afferent sources modify rhythmic behavior in many preparations. Functional interpretations have often been based solely on neural responses and mechanical information has been lacking. When mechanical and neural factors have been studied in conceit, reflexes have shown strong functional neuromechanical effects. Muscle reflexes seem particularly important for body weight support and step cycle timing, while cutaneous reflexes function in stumble correction and placing reactions during swing phase of gait in cats and humans. We present a framework for conceptualizing reflex function during locomotion.
