Visual suppression on body sway during standing on a foam rubber mat was investigated in 82 normal subjects, 44 patients with peripheral vestibular disorders and 42 patients with cerebellar or brain stem lesion.
As a result, visual suppression score on static posture in patients with cerebellar or brain stem lesion was lower than the score in both normal subjects and patients with peripheral vestibular disorders.
The significance of the difference at the 0.01 level was confirmed statistically.
Visual suppression on static posture is an available test in clinical differential diagnostic procedures to distinguish between peripheral and central vestibular disorders.
