基于生物力学数据的足底特征区域划分

Plantar feature region division based on biomechanical data

背景:目前对足底区域的划分通常基于解剖学,没有考虑每个个体独特的足底生物力学因素,无法反映每个个体足底受力的个性化特征。目的:基于生物力学角度对足底区域进行划分,得到能反映个体足底受力特征的足底区域划分图谱。方法:以某正常人步行为例,通过F-scan鞋垫式足底压力测量系统获得其足底压力分布随时间的变化情况。基于生物力学数据,采用聚类分析方法划分足底特征区域,形成足底区域划分的个性化图谱。结果与结论:基于生物力学数据,采用聚类分析方法得到的足底区域划分个性化图谱,可以作为反映该个体步行时足底受力特征的指标,利用位于足底特征区域几何中心处的少量传感器就能较好地反映出该个体运动过程中足底的受力特点。

BACKGROUND:The current division of the plantar area is usually based on anatomy,without considering the unique plantar biomechanics factors of each individual,and unable to reflect the personalized characteristics of each individual’s plantar stress.OBJECTIVE:To classify the plantar region from the perspective of biomechanics,and to obtain the map of plantar region that can reflect the stress characteristics of individual planta.METHODS:Taking a normal person walking as an example,the change of plantar pressure distribution with time was obtained by using F-scan insole pressure measurement system.Based on biomechanical data,the characteristic regions of the soles of the foot were divided by cluster analysis to form a personalized map of the soles of the foot.RESULTS AND CONCLUSION:Based on biomechanical data,the personalized map of plantar region division obtained by the cluster analysis can be used as an index to reflect the characteristics of the individual’s plantar stress.A small number of sensors located at the geometric center of the plantar feature area can better reflect the characteristics of the individual’s plantar stress during the movement.
