    摘要:

    目的 通过运动生物力学手段从动、静态两个方面评价不同足型受试者足踝功能的差异,为足踝运动研究提供理论支持和参考依据。方法 对65名受试者以足弓指数区分成扁平足、低弓足和正常足3组,采用单因素方差分析3组受试者静、动态足踝功能指标的差异。结果 在静态足踝功能方面,正常足踝关节适应性(malleolar valgus flexibility,MVF)显著高于低弓足和扁平足(P<0.05);在纵弓适应性(arch height flexibility,AHF)上,负重对正常足的影响相比于扁平足较小(P<0.05),3组横弓适应性(transverse arch flexibility,TAF)无统计学意义。在动态足踝功能上,缓冲阶段正常足在受力偏移幅度和时间均高于其他两组(P<0.05);在过渡阶段,正常足相比于低弓足和扁平足,过渡时间显著降低(P<0.05);在蹬伸阶段,正常足在蹬伸时间和蹬伸速度显著高于扁平足(P<0.05)。结论 负重增加时,低弓足和扁平足后足姿势维持能力和纵弓形态维持能力相比于正常足较差;低弓足和扁平足的足弓刚性和足底弹性相比于正常足较差,正常足在行走时表现出更好的承重缓冲能力、弹性向刚性过渡能力以及蹬伸效率。系统全面的评测体系对足踝损伤风险预测、运动能力评估具有重要意义。

    Abstract:

    Objective To evaluate the difference of foot-ankle function for subjects with different foot types from both dynamic and static aspects by means of sports biomechanics, so as to provide theoretical support and references for the study of foot-ankle movement. Methods According to the arch index, 65 subjects were divided into three groups: flat foot, low arch foot and normal foot. One-way ANOVA was used to analyze the difference of static and dynamic foot-ankle function indexes among the three groups. Results In terms of static foot-ankle function, the malleolar valgus flexibility (MVF) of normal foot and ankle was significantly higher than that of low arch foot and flat foot (P<0.05), while in terms of arch height flexibility (AHF), the effect of weight bearing on normal foot was smaller than that of flat foot (P<0.05), but there was no significant difference in transverse arch flexibility (TAF) among the three groups. In terms of dynamic foot-ankle function, the force offset amplitude and time of normal foot at buffer stage were higher than those of the other two groups (P<0.05), and at transition stage, the transition time of normal foot was significantly lower than that of low arch foot and flat foot (P<0.05). At pedal-extension stage, the pedal-extension time and speed of normal foot were significantly higher than those of flat foot (P<0.05). Conclusions The posture maintenance ability and longitudinal arch shape maintenance ability of low arch foot and flat foot are worse than those of normal foot with the load increasing, and the arch rigidity and plantar elasticity of low arch foot and flat foot are worse than those of normal foot, and normal foot shows better load-bearing cushioning ability, elastic-to-rigid transition ability and pedal extension efficiency during walking. A systematic and comprehensive evaluation system is of great significance to the prediction of foot-ankle injury risk and the evaluation of sports ability.
