关于非病理性扁平足和高弓足是否影响人类行走活动，一直存在争议。3D足部扫描系统被用来获取采用半负重姿势的受试者的静态足迹。根据他们的脚印，受试者被分为两组：平足和高弓。足底压力测量系统用于测量和记录受试者连续的自然步态。提出了两个指标：足底垂直地面反作用力分布和足印面积变化率。用这两项指标对两组受试者的自然步态进行比较发现：(1)在站立相，足底VGRF的分布有显著差异(p<；0.01)；(2)在一个步态周期中，足底面积的变化率也有显著差异(p<；0.01)。我们的分析表明，步行时，足底的VGRF给平足带来更大的肌肉张力，而较小的足迹面积变化率给高弓带来更大的稳定性。
There has been a controversy as to whether or not the non-pathological flat foot and high-arched foot have an effect on human walking activities. The 3D foot scanning system was employed to obtain static footprints from subjects adopting a half-weight-bearing stance. Based upon their footprints, the subjects were divided into two groups: the flat-footed and the high-arched. The plantar pressure measurement system was used to measure and record the subjects' successive natural gaits. Two indices were proposed: distribution of vertical ground reaction force (VGRF) of plantar and the rate of change of footprint areas. Using these two indices to compare the natural gaits of the two subject groups, we found that (1) in stance phase, there is a significant difference (p<0.01) in the distributions of VGRF of plantar; (2) in a stride cycle, there is also a significant difference (p<0.01) in the rate of change of footprint area. Our analysis suggests that when walking, the VGRF of the plantar brings greater muscle tension to the flat-footed while a smaller rate of change of footprint area brings greater stability to the high-arched.
