Abstract

A three-partition distributed force platform (3P-DFP) is proposed to measure the plantar pressure distribution, and foot support characteristics are evaluated with the obtained pressure distribution information. Twenty-seven young adults and 40 elderly adults were randomly recruited to perform the test in three phases: double-leg stance with eyes closed, double-leg stance with eyes opened, and single-leg stance with eyes opened. The evaluation parameters of foot support surface characteristics and support point characteristics were calculated based on the average position information of the center of pressure in the lateral of sole, media of sole, posterior of heel, and entire pelma. The results showed that the support width of the foot sole was significantly greater in the elderly group (p <0.01), but the overall support area showed a decreasing trend. The CoP excursion in the media-lateral direction was significantly higher in the elderly group from double-leg stance to single-leg stance (p <0.01). The CoP trajectory in the elderly group tends to shift in a medial direction with increasing age or postural difficulty.

通过基于三部分分布式力平台的足底测量，评估年轻人和老年人的足部支撑特性。

提出了一种三分区分布式力平台（3P-DFP）来测量足底压力分布，并根据获得的压力分布信息评估足部支撑特性。随机招募了 27 名青壮年和 40 名老年人，分三个阶段进行测试：闭眼双腿站立、睁眼双腿站立和睁眼单腿站立。根据压力中心在足底外侧、足底中侧、足跟后侧和整个骨盆的平均位置信息，计算出足部支撑面特征和支撑点特征的评价参数。结果表明，老年人组的足底支撑宽度明显更大（p
