Relationship between movements of the head and the center of gravity of the body in Menière's disease.
The body sway of the patients with unilateral and bilateral Ménière's disease was recorded by using a cephalograph and a stabilometer, and analyzed with a microcomputer. The results show that the locus type, locus area and locus length traced by the head's center and the body's center of gravity are useful parameters of the body sway, representing the characteristics of peripheral vestibular disorders. The noteworthy characteristics are shown in the right-and-left type and forward-and-backward type in statokinesigram, in the significant differences of locus area and/or locus length between the head movement and the movement of the center of gravity, and the change of the averaged divisional frequencies of the body sway with eye-closing.
