中文摘要:

旨在解决人工足弓指数测量精度低和效率低的缺点,提出用足底支撑面动态信息对足弓指数进行测量。从研制的分布力测力台中获取足跟区、脚掌外侧区和脚掌内侧区的地面反作用力的作用点轨迹,将 3 个点形成的面积 SΔ ABC 用来对支撑面信息进行表达,获得 5 次 30 s 双足站立姿势任务的 SΔ ABC 的均值 MSΔ ABC ,作为足部的弓高指数(FAI)的关键参数。采用组合卡尺弓高测试方法(AHIMS)对 30 名受试者的足弓类型进行划分,对 FAI 值进行方差分析。结果显示,FAI 值从低足弓组、正常足组到高足弓组呈逐渐升高趋势,低足弓组与高足弓组(P<0. 001)、正常足与高足弓组(P<0. 01)之间具有显著差异。结果表明足底支撑面的动态信息 SΔ ABC 可以对足部的弓高指数进行表达。

英文摘要:

In order to solve the shortcomings of low accuracy and low efficiency of artificial arch index measurement. It is proposed to use the dynamic information of the plantar support surface to measure the arch index. Obtain the trajectory of the ground reaction force on the heel, the outside of the sole, and the inside of the sole from the developed distributed force plate. The area SΔ ABC formed by the three points is used to express the support surface information. The mean value MSΔ ABC of SΔ ABC for five 30-second bipedal standing posture tasks was obtained as a key parameter of the foot arch height index (FAI). The combined caliper arch height index measurement system (AHIMS) was used to classify the foot arch types of 30 subjects, and the FAI value was analyzed by variance. The results showed that the FAI value gradually increased from the low arch group, the normal foot group to the high arch group. There was a significant difference between the low arch group and the high arch group (P<0. 001), and between the normal foot and the high arch group (P< 0. 01). The results show that the dynamic information SΔ ABC of the plantar support surface can express the arch height index of the foot.
