High-heeled women have been identified with balance control problems. The purposes of this study were to objectively quantify the displacements and velocities of center-of-pressure (COP) of body during waist pulling and to compare the differences between barefooted and high-heeled situations. We used a waist pulling system which has three different magnitudes to sway the subjects. We found that the kinematic information of barefooted and high-heeled women’s COP is very important in understanding the mechanism of postural balance control of women in every-day life. In the high-heeled’s case, the displacement of COP increases by 9% (1kg), 33% (2kg), 44% (3kg) as against bare footed. Also the velocity of COP grows two times than that of the bare footed. COP analysis in postural balance study of high-heeled women is considered useful in development of the safety systems that prevent high-heeled women from falling.
