高跟鞋全掌中底硬度对青年女性行走过程中步态特征与稳定性的影响

Effects of Full Palm Midsole Hardness of High Heels on Gait and Stability of Young Women During Walking

为了减少长期穿着高跟鞋对女性足部健康产生的不利影响,研究选取40名青年女性穿着3双不同全掌中底硬度的高跟鞋,采用Footscan^(R)足底压力测量系统与RSscan^(R)测力台同步使用,对其自然行走时步态周期、足底压力中心轨迹以及峰值压力、峰值压强、压强-时间积分等足底动力学特征进行测试。结果显示:随着全掌中底硬度的降低,前掌着地时间变长,全掌着地时间变短,足部外翻程度明显减小,内翻程度明显变大。较低的中底硬度具有良好的缓冲性能和保护性能。研究对于提升高跟鞋穿着稳定性及舒适性具有重要的参考价值,可为制鞋行业在高跟鞋中底材质的选择与研发方面提供科学可靠的理论支持。

To improve the health of women's feet damaged by daily wearing high heels,40 young women were selected to wear 3 pairs of high heels with full palm midsole material of different hardness.The Footscan^(R) plantar pressure measurement system was used simultaneously with RSscan^(R) force platform to test their gait cycle,center of pressure(COP)and plantar dynamics characteristics including maximum force,peak pressure,and pressure-time integral during natural walking.Results showed that,with the decrease in midsole hardness,the forefoot contact phase(FFCP)became longer,the foot flat phase(FFP)became shorter,the supination degree decreased significantly,and the pronation degree increased significantly.This study has important reference value for improving the comfort and stability of high-heeled shoes,and can provide scientific and reliable theoretical support for the selection and development of high-heeled midsole materials.
