本研究探讨了鞋跟高度对生物踝-足系统侧倾特性的影响。10名健康的成年女性志愿者穿着三双鞋跟高度不同的鞋子走路，每双鞋子以三种步行速度行走。收集了计算参与者踝足系统翻滚形状所需的运动学和动力学数据。翻转形状是踝足系统在脚跟接触和相对脚跟接触之间符合的有效摇杆几何形状。使用与侧翻形状最匹配的圆弧参数来检查鞋跟高度对踝足系统的影响。研究结果支持了这样一种观点，即非残疾人会自动调整他们的踝足系统，以适应一系列的鞋跟高度，从而导致翻滚形状不会发生明显变化。考虑到生理限制，这种适应性对于非常高的高跟鞋可能是不可能的。
This study investigated the effects of shoe heel height on the rollover characteristics of the biologic ankle-foot system. Ten nondisabled adult female volunteers walked using three pairs of shoes with varying heel heights and at three walking speeds with each pair of shoes. Kinematic and kinetic data needed to calculate the rollover shapes of the ankle-foot systems of the participants were collected. Rollover shapes are the effective rocker geometries that ankle-foot systems conform to between heel contact and opposite heel contact. Parameters of the best-fit circular arcs to the rollover shapes were used in an examination of the effects of shoe heel height on the ankle-foot system. The results support the notion that nondisabled humans automatically adapt their ankle-foot systems to accommodate a range of shoe heel heights, resulting in rollover shapes that do not change appreciably. Given physiologic constraints, this adaptation may not be possible for very high heels.
