要約(日本語)：We investigated the effects of Galvanic Vestibular Stimulation（GVS）on balance through changes in gravity center sway．It was suggested that body tilting during stimulation may affect gravity center sway．In this study，the integral of the difference between center of mass sway（COM）calculated from body tilt angle，and center of pressure sway（COP）measured by a sway meter，was assumed to be “resistance force against body tilting” in one healthy subject．The correlation between this value and volatility of position vector changes before and after stimulation was determined．A positive correlation coefficient of 0.64 was obtained for anode direction，indicating that body tilting affects gravity center sway．Further validation will be pursued with more subjects．
