Overview: This paper examines the influence of vestibular and leg proprioceptive inputs on the human upright posture. Vestibular input was changed by applying current 1 mA between places near to left and right ear. Proprioceptive input was modified by vibrating the calf muscle. Furthermore, the vestibular stimulus was combined with the muscle vibration using five different temporal relationships between the stimuli. The result shows that the body vertical is under the continuous control of leg proprioceptive and vestibular inputs. It presents a simply model according to which these inputs are averaged by a summation process of several sensory inputs through a parallel sensory feedback in the human posture control system.
