Posturography is considered to be useful for analyses of equilibrium disturbance. There are various ways of analyzing body sway. Recently the author measured the deviation of body sway to evaluate the roles of proprioceptors of the neck and extrinsic eye muscles and examined the velocity of body sway to observe the characteristics of equilibrium disturbance in general.(1) The relationship between the direction of the head and the deviation of body sway was observed. When a subject turned his head to the right, the center of his body sway often deviated to the left. Similarly, when he turned his head to the left, the the center of his body sway often deviated to the right. This tendency was observed frequently in sportsmen, but scarcely observed in normal subjects.(2) Smilary, the relationship between the direction of eyes and the direction of body sway was observed. The center of body sway often deviated to the opposite side of the direction of eyes.(3) The velocity of body sway to the back was faster than to the front in the majority of healthy people with eyes closed, but in patients with labyrinthine disorder, the velocity to the front was faster than to the back.(4) Severe stimulation with an air caloric system (24°C, 40sec.) on labyrinthines of healthy people with eyes closed increased the velocity to the back, but weak stimulation (30°C, 5-10sec.) often increased the velocity to the front.
