Characteristics of body sway in patients with peripheral vestibular disorders

Measuring the movement of the body's center of gravity during standing with the eyes open and with the eyes closed, proved to be a useful test in vestibular investigation. 30 patients with peripheral vestibular disorders were tested using a static sensonograph and a digital computer. Three types of locus patterns, the lateral deviation of the averaged position and two types of frequency spectral patterns obtained from the movement of the center of gravity were the characteristics of the body sway in the patients with peripheral vestibular disorders.
