Postural deviation evoked by caloric stimulation during upright standing in man.
To understand a disequilibrium of the peripheral vestibular disorders, we tried to analyze the body sway evoked by unilateral or bilateral caloric stimulation with warm and cold water systematically. As for postural deviation, the results of our study are summarized as follows. Unilateral warm stimulation evokes heterolateral and anterior postural deviation. Unilateral cold stimulation evokes homolateral and anterior postural deviation. Bilateral warm stimulation evokes posterior postural deviation. Bilateral cold stimulation evokes anterior postural deviation. Therefore we consider that there are several patterns of static disequilibrium of upright posture in the peripheral vestibular disorders.
