Posturography has been used for evaluating deviation in the Romberg test. For this purpose, the curves of body sway were analyzed with the aid of a signal processor, using the program of probability density histogram. According to this analyzing system, the center and the magnitude of curves of body sway are expressed in terms of mean values and variation, respectively. The difference between the center of body sway with the eyes open and that with the eyes closed is considered to represent the deviation in the Romberg test. In this paper, the standing posture is evaluated mainly in terms of deviation during the Romberg test.1. Normal subjects tend to shift forward when their eyes are closed.2. Of the patients with equilibrium disturbance, there are many who deviate backward when their eyes are closed.3. The forward deviation is restored when the patient with equilibrium disturbance recover from vertigo.4. It seems that vision controls the body sway in the lateral direction.
