The sways of human body standing on the rotating table with eyes closed were measured for movements of the body center of gravity by means of a statokinesimeter. The energies of the sways in each of the following 6 states (A)〜(F) were calculated from the measured RMS values of amplitude. That is, (A): 1min. before rotation, (B): during counterclockwise rotation, (C): 1min. after rotation (after disappearance of dizzy feeling), (D): 1min. before rotation after the rest of 2min., (E): during clockwise rotation, (F): 1min. after rotation. As the index of motion sickness susceptibility, the ratios of C/A, D/A, F/A, and E/B, and the average values of those 4 items were evaluated, where A is the energy of the sway in the state of (A), ……and F is that of (F). The average value was named motion sickness susceptibility index (MSI) by authors. The values of MSI were compared with motion sickness susceptibility scores (MSQ scores) which were determined by means of the questionnaire proposed by J.M. Lentz et al. (1977). The correlation coefficient between MSI's and MSQ scores was 0.857.
