N2 - Previous studies have reported that postural coordination patterns change as a function of translation frequency. However, the effect of inclined support surface on postural strategy was not clear. Therefore, the purpose of this study is to investigate the influence of inclined support surface on postural strategy during platform translations. Eight healthy adults maintained their balance in stance during support surface translations in the anterior-posterior direction at two different frequencies (0.2 and 0.8[Hz]) and at three different base of support condition (LV: Level, TD: Toe Down, TU: Toe Up). For the kinematic data at slow frequency, subjects rode the platform depending on the movement of platform itself, while at fast frequency subjects fixed their head and center of mass (COM) in space. For the kinetic data at slow frequency, the ankle moment amplitude is similar among all support surface conditions, while at fast frequency the ankle moment amplitude for TU is significantly larger than LV. Result shown that the effect of inclined surface on postural strategy changed according to frequency of support surface translations.
