title: Evidence of interaction between human lumbosacral and cervical neural networks during gait.
abstract: Changes in H-max amplitude resulting from alteration in arm position have been used with changes in gait double support durations resulting from similar changes in arm posture to investigate interaction, if any, between the lumbosacral and cervical neural networks in seven normal subjects. Since the reflex and gait responses of each lower limb were altered by changes in upper limb position, it was suggested that in humans also, there may be interaction not only in a static situation, but also during gait between the lumbosacral and cervical neural networks. The responses of the right leg were always greater than those of the left leg irrespective of the arm position; This retention of inter-limb relation may indicate a dominance of the lumbosacral neural network over its cervical counterpart.
