To clarify the characteristics of disequilibrium in patients with equilibrium disturbances, we investigated head movement (H. M. ) and movement of the body's center of gravity (M. C. G. ), using a cephalograph to record H. M., a strain-gauge platform to record M. C. G. and a technical computer. Patients were instructed to stand with feet close together on the platform with eyes open and then with eyes closed, for periods of 60 seconds each. The results were as follows:<BR>1) In 4 patients with peripheral vestibular disorders, the area and total length of locus traced by H. M. and M. C. G. were greater than in normal controls, especially with eyes closed. The ratio of the total length of locus traced by H. M. to that of M. C. G. was also greater in the patients than in normal controls. The patients tended to sway laterally.<BR>2) In 6 patients with spinocerebellar degeneration, the area and total length of locus traced by H. M. and M. C. G. were greater than in normal controls. The averaged divisional frequencies in an anteroposterior direction were also greater in the patients.<BR>3) In 13 patients with Parkinson's disease, the total length of locus traced by M. C. G. with eyes open was larger than in normal controls, while the area of H. M. was smaller. The ratio of the total length of locus traced by H. M. and M. C. G. with eyes closed to those with eyes open was smaller in the patients than in normal controls.<BR>4) In 4 patients with acoustic neurinoma, most parameters of H. M. and M. C. G. did not differ from those of normal controls.<BR>These results suggest that patients with equilibrium disturbances have a pattern of body sway specific to the disease.
