摘　　要：目的 探讨不同站姿时足底压力分布与足弓结构特征之间的相关性。方法 对13名健康成年男性进行足底压力测试,并进行足部CT扫描和足骨模型重构,建立足弓数字化表征。在此基础上,分析足底压力测量指标与足弓特征测量参数之间的相关性。结果 前足峰值压力(forefoot peak pressure,FPP)在0°站姿时与内外侧纵弓高度、内外侧纵弓指数和体质量正相关,与内外侧纵弓角负相关;在30°站姿时与内外侧纵弓长度、内侧纵弓高度、足底三角形面积和体质量正相关;在60°站姿时与内外侧纵弓高度和内侧纵弓指数正相关,与内侧纵弓角负相关。中足峰值压力(midfoot peak pressure,MPP)在0°站姿时与内外侧纵弓长度和足底三角形面积正相关;在30°站姿时与内外侧纵弓长度、内外侧纵弓角和足底三角形面积正相关,与内外侧纵弓指数负相关;在60°站姿时与内外侧纵弓长度、足底三角形面积和体质量正相关。后足峰值压力(rearfoot peak pressure,RPP)在0°站姿时与内外侧纵弓高度、内外侧纵弓指数和体质量正相关,与内外侧纵弓角负相关;在30°和60°站姿时仅与体质量正相关,与足弓特征参数无关。结论 不同站姿时的足底压力分布与足弓特征存在不同相关性。研究结果可为临床诊断、治疗和预防因不同站姿引起的足部病理提供理论基础。Objective To explore the correlation between plantar pressure distributions and arch structural features in different standing positions.Methods Plantar pressures of 13 healthy adult males were tested,and foot CT scan and foot bone model reconstruction were then performed to establish arch digital characterization.On this basis,the correlation between plantar pressure measurement indexes and arch characteristics measurement parameters was analyzed.Results Forefoot peak pressure(FPP) was positively correlated with the medial/lateral longitudinal arch height,the medial/lateral longitudinal arch index and body weight,and negatively correlated with the medial/lateral longitudinal arch angle during standing with foot at 0°;it was positively correlated with the medial/lateral longitudinal arch length,the medial longitudinal arch height,the plantar triangle area and body weight during standing with foot at 30°;it was positively correlated with the medial/lateral longitudinal arch height and the medial longitudinal arch index,and negatively correlated with the medial longitudinal arch angle during standing with foot at 60°.Midfoot peak pressure(MPP) was positively correlated with the medial/lateral longitudinal arch length and the plantar triangle area during standing with foot at 0°;it was positively correlated with the medial/lateral longitudinal arch length,the medial/lateral longitudinal arch angle and the plantar triangle area,and negatively correlated with the medial/lateral longitudinal arch index during standing with foot at 30°;it was positively correlated with the medial/lateral longitudinal arch length,the plantar triangle area and body weight during standing with foot at 60°.Rearfoot peak pressure(RPP) was positively correlated with the medial/lateral longitudinal arch height,the medial/lateral longitudinal arch index and body weight,and negatively correlated with the medial/lateral longitudinal arch angle during standing with foot at 0°;it was only positively correlated with body weight,but not with c
