The aim of this study was to evaluate the influence of vestibulo-spinal drive on the performance of various locomotor-like movements. The extent of body rotation was assessed during walking (1 Hz and 2 Hz), running and hopping in place after vestibular stimulation (10 body rotations; 0.5 Hz). Compared to the controls, body rotations with eyes closed were larger during hopping than while running and smallest during walking independent of stepping frequency. A close correlation existed between the absolute duration of stance phase of the two legs and the rotation of the body. It is suggested that the amount of proprioceptive feedback from the legs determines the influence of vestibulo-spinal input on body movement.
本研究的目的是评估前庭脊髓驱动对各种类似运动的运动表现的影响。在前庭刺激（10次身体旋转；0.5Hz）后，评估在行走（1Hz和2Hz）、跑步和原地跳跃过程中的身体旋转程度。与对照组相比，闭眼时身体旋转在跳跃时比跑步时更大，在行走时最小，且与步频无关。双腿站立期的绝对持续时间与身体旋转之间存在密切相关性。研究表明，来自腿部的本体感觉反馈量决定了前庭脊髓输入对身体运动的影响。
