Description

Postural responses of subjects who feel dizzy on a rotating table were observed. The sways of the head and of the body center of gravity were rocorded and analyzed by means of their frequency power spectra and their Lissajous's figures. When the rotating direction of the table is reversed, the rotating direction of the body center of gravity of a subject on the table is very likey to be also reversed. As the subject sways standing with eyes open, the center of sway shifts leftward (rightward) with the table rotated clockwise (counter-clockwise), although the center of sway of the subject standing with eyes closed indicates no shift. As the angular velocity of the rotating table is increased, durations of nystagmus and dizziness of the subject get longer. The analysis of power spectra and the Lissajous's figures for the various foot positions shows that power spectra for the Mann's posture, indicating greater instability, was composed much of higher frequency.
