Foot binding has a long and influential history in China. Little is known about biomechanical changes in gait caused by bound foot. The purpose of this study was to investigate the differences in lower limb kinematics between old women with bound feet and normal feet during walking. Six old women subjects (three with bound feet and three controls with normal feet) volunteered to participate in this study. Video data were recorded with a high speed video camera and analysed in the SIMI motion analysis software. Compared to normal controls, bound feet subjects had faster gait cadence with shorter stride length as well as smaller ankle and knee range of motion (ROM). During preswing phase, ankle remained to be dorsiflexion for bound foot subjects. The data from bound foot group also demonstrated that toe vertical displacement increased continuously during whole swing phase without a minimum toe clearance (MTC). The findings indicate that older women with bound feet exhibit significant differences in gait pattern compared to those with normal feet, which is characterised by disappeared propulsion/push-off and reduced mobility of lower limb segments.
缠足在中国有着悠久且具有影响力的历史。关于缠足导致的步态生物力学变化，人们了解甚少。本研究的目的是调查老年缠足女性和正常足女性在行走过程中下肢运动学的差异。六名老年女性受试者（三名缠足者和三名正常足对照者）自愿参与本研究。用高速摄像机记录视频数据，并在SIMI运动分析软件中进行分析。与正常对照组相比，缠足受试者的步态步频更快，步幅更短，踝关节和膝关节的活动范围（ROM）也更小。在摆动前期，缠足受试者的踝关节仍保持背屈。缠足组的数据还表明，在整个摆动阶段，脚趾垂直位移持续增加，没有最小脚趾间隙（MTC）。研究结果表明，老年缠足女性与正常足女性相比，步态模式存在显著差异，其特征是推进/蹬离消失，下肢节段活动度降低。
