Abstract :
To understand a posture control system, the identification technique was applied to data of antero-posterior sway under different conditions including a sway-referenced support. In the case of a sway-referenced support, forward inclination increased. Gain of (ankle moment)/(sway angle) also increased in the high frequency range and gain characteristics were similar to that of a semicircular canals model
