摘要/Abstract

摘要： 为了探究不同支撑垫结构对足底压力分布的影响,用扫描仪获取9名扁平足青年女性3种负重状态（全负重、半负重和非负重）足部模型,定制3种支撑型鞋垫（Ⅰ型、Ⅱ型、Ⅲ型）;通过足底压力测试系统,分析3种支撑型鞋垫对扁平足步行支撑期触地时间分配、足底压力中心分布的影响,同时进行主观舒适性评价。结果显示,相较于无支撑鞋垫,Ⅱ型、Ⅲ型鞋垫明显降低了支撑期总触地时间（P=0.002、P=0.026）;3种支撑型鞋垫使支撑期COP轨迹均向内侧偏移,偏移幅度随支撑垫高度的增加而增加。合适的支撑型鞋垫可以优化支撑期触地时间与COP轨迹,为扁平足个性化矫正鞋垫的设计提供了理论依据。

Abstract: To investigate the effects of different arch-support structures on plantar pressure distribution, a scanner was used to obtain three weight-bearing conditions (full-weight-bearing,semi-weight-bearing,and non-weight-bearing) foot models of nine young women with flat feet. Three types of arch-support insoles (Type I, Type II, and Type III) and one type of non-support insole were customized; the plantar pressure test system was used to compare the distribution of contact time and plantar pressure distribution characteristics of the three types of arch-support insoles during the stance phase of gait of flat feet. Subjective ratings including static comfort and dynamic comfort were assessed for each participant. The results showed that compared with unsupported insoles, type II and type III insoles significantly reduced the total contact time during the stance phase (P=0.002 and P=0.026, respectively); all three types of arch-support insoles shifted the COP trajectory medially during the stance phase, and the shifting increased with the increase of the height of the supportive structure. The appropriate arch support insoles can optimize the contact time and COP trajectory during the stance phase, which provides a theoretical basis for the design of personalized orthopedic insoles.
