摘要

本研究針對穿著夾腳、非夾腳拖鞋和赤腳時的人體步態著地期各項生物力學參數（包括行走速度、足跟著地階段及前足推蹬階段時間比例，髖、膝、踝關節角度，主動力峰值、撞擊力峰值、最大負荷率和力矩等對地作用力數據，足跟著地階段及前足推蹬階段摩擦係數）進行比較。實驗使用VICON動作分析系統進行相關資料之擷取。受試者為10名下肢無特殊傷害之男性大專生，分別穿著藍白夾腳拖鞋、藍白拖鞋與赤腳以三種不同步行速度進行測試。統計以SPSS軟體之二因子重複量數變異數分析進行，顯著水準定為α=.05。結論：一、穿著不同拖鞋以不同速度行走，雖然會對於行走著地期足跟著地階段及前足推蹬階段的時間比例造成全面性的影響；但是對於人體行走速度而言，不同拖鞋並不會造成影響。二、撞擊力峰值及最大負荷率關係到鞋子本身的避震表現，由結果可知不同拖鞋和不同走路速度自身對於撞擊力峰值及最大負荷率都有影響；但若考慮到交互作用，不同鞋子和不同走路速度僅對於鞋子的最大負荷率表現造成影響。三、主動力峰值，最大和最小力矩，足跟著地及前足推蹬階段摩擦係數峰值關係到鞋子本身的功能性表現，由結果可知穿著不同鞋子和不同走路速度對於最大力矩造成個別和交互作用影響，對於最小力矩、足跟著地及前足推蹬階段摩擦係數峰值則僅有個別影響。至於主動力峰值，則是在改變行走速度或者在同時改變行走速度和穿著的鞋子時，會產生差異。四、人體的下肢動作會產生改變以因應穿著不同拖鞋以不同速度行走，其中行走速度改變會造成髖關節伸展動作和踝關節外翻角度產生變化；不同拖鞋和行走速度對於膝、踝關節的屈曲與伸展動作則會造成不同層面的影響。

In this research, human gait biomechanical parameters in stance phase when wearing flip-flops, slipper or barefoot to walk (including walking velocity, the time ratio of heel-contact-ground stage to forefoot-push-off stage, the joint angle of hip, knee and ankle, data of the peak of active force, the peak of impact force, maximum loading rate and
moment concerning the force produced by human body when acting to the ground, coefficient of friction in heel-contact-ground and forefoot-push-off stage) were aimed to compare. In experiment, VICON motion analysis system was used to capture relating data when ten male college students without specific injuries in lower extremity wearing blue-white flip-flops, blue-white slipper or barefoot respectively to walk in three different velocities. Statistics were completed by two-way repeated measure ANOVA using SPSS software. Significant level was set at α=.05. Results: 1. Although different slippers and different walking velocity would influence the time ratio of heel-contact-ground stage to forefoot-push-off stage synthetically, different slippers couldn’t affect walking velocity. 2. The peak of impact force and maximum loading rate would influence the performance of shock absorbing. Different slippers and walking velocities would affect these two parameters, but only the maximum loading rate would be affected interactively by different slippers and walking velocities. 3. The peak of active force, maximum and minimum moment, coefficient of friction in heel-contact-ground and forefoot-push-off stage would influence the functional performance of shoe. Different slippers and walking velocities would affect maximum moment respectively and interactively, but only affecting minimum moment, coefficient of friction in heel-contact-ground and forefoot-push-off stage respectively. As for the peak of active force, it would be influenced by different walking velocities respectively and by different slippers and walking velocities interactively. 4. When wearing different slippers and changing different walking velocity to walk, the movement of lower extremity would change. The changing of walking velocity would cause the variation of hip extension and ankle eversion. For these movement including the flexion and extension of knee and ankle joint, different slippers and walking velocities would cause different effects.
