Spontaneous sway of the head during standing were studied in both twelve healthy adults (9 women and 3 men) and eleven patients with dysequilibrium of the peripheral vestibular and central origin. The newly devised "light spot tracker" (Tokumasu) was used for recording of the head movements. The results was as follows; 1) anterior-posterior sway was nearly always larger than lateral sway in all subjects with eyes open and with eyes closed, 2) maximum values of physiological head movements in normal subjects with eyes open were 6.1cm in anterior-posterior direction and 5.3cm in right-left direction. When eyes were closed, these values changed to 6.7cm and 4.8cm respectively, and 3) in the patients with the central disorder, lateral sway was larger when eyes open than when eyes closed, to the contrary, anteriorposterior sway was larger when eyes closed than when eyes open. It is assumed that analysis of the mode of swaying in both anterior-posterior and lateral dimensions gives us a cue of differential diagnosis between the peripheral vestibular and the central diseases.
