Abstract
High-heeled shoes are associated with instability and falling, leading to injuries such as fracture and ankle sprain. This study investigated the effects of habitual wearing of high-heeled shoes on the body's center of mass (COM) motion relative to the center of pressure (COP) during gait. Fifteen female experienced wearers and 15 matched controls walked with high-heeled shoes (7.3cm) while kinematic and ground reaction force data were measured and used to calculate temporal-distance parameters, joint moments, COM-COP inclination angles (IA) and the rate of IA changes (RCIA). Compared with inexperienced wearers, experienced subjects showed significantly reduced frontal IA with increased ankle pronator moments during single-limb support (p<0.05). During double-limb support (DLS), they showed significantly increased magnitudes of the frontal RCIA at toe-off and contralateral heel-strike, and reduced DLS time (p<0.05) but unaltered mean RCIA over DLS. In the sagittal plane experienced wearers showed significantly increased mean RCIA (p<0.05) and significant differences in the RCIA at toe-off and contralateral heel-strike (p<0.05). Significantly increased hip flexor moments and knee extensor moments at toe-off (p<0.05) were needed for forward motion of the trailing limb. The current results identified the change in the balance control in females after long-term use of high-heeled shoes, providing a basis for future design of strategies to minimize the risk of falling during high-heeled gait.
