目的 观察男大学生左足正常步态、右足外八字步态行走过程中足底压力的特征.方法 运用比利时Footscan系统对邯郸职业技术学院20～ 25岁的男大学生进行足底压力测试,通过分析筛选出左足为正常步态、右足为外八字步态的42名大学生进行研究.结果 正常步态足峰值压强在第3跖骨(45.05±13.91) N/cm2、足弓(4.48±1.94) N/cm2两区域显著高于外八字步态足第3跖骨(26.83±10.82)N/cm2、足弓(2.90±1.57) N/cm2 (P ＜0.05)；正常步态足达峰值压强时间在第1跖骨(436.28±73.09) ms区域的显著早于外八字步态足第1跖骨(477.47 ±33.52)ms(P＜0.05),在第4跖骨(424.56±83.46)ms区域显著晚于外八字步态足第4跖骨(369.39±103.079)ms(P ＜0.05)；正常步态足冲量在第2～5趾骨(4.56±5.54)N·s、第2跖骨(41.20±21.44)N·s两区域显著低于外八字步态足第2～5趾骨(8.25±8.30)N·s、第2跖骨(61.46 ±36.14)N·s(P＜0.05).结论 外八字步态足与正常步态足相比,足底压力中心偏向足的内侧,导致蹬伸时的推进力不是直线向前,而是斜向的,行走方向上的蹬地效果较差；并且会在胫骨和腓骨之间产生一个扭力,相应使胫骨出现内翻,可能引起膝关节过度的摩擦,导致损伤.
目的 觀察男大學生左足正常步態、右足外八字步態行走過程中足底壓力的特徵.方法 運用比利時Footscan繫統對邯鄲職業技術學院20～ 25歲的男大學生進行足底壓力測試,通過分析篩選齣左足為正常步態、右足為外八字步態的42名大學生進行研究.結果 正常步態足峰值壓彊在第3蹠骨(45.05±13.91) N/cm2、足弓(4.48±1.94) N/cm2兩區域顯著高于外八字步態足第3蹠骨(26.83±10.82)N/cm2、足弓(2.90±1.57) N/cm2 (P ＜0.05)；正常步態足達峰值壓彊時間在第1蹠骨(436.28±73.09) ms區域的顯著早于外八字步態足第1蹠骨(477.47 ±33.52)ms(P＜0.05),在第4蹠骨(424.56±83.46)ms區域顯著晚于外八字步態足第4蹠骨(369.39±103.079)ms(P ＜0.05)；正常步態足遲量在第2～5趾骨(4.56±5.54)N·s、第2蹠骨(41.20±21.44)N·s兩區域顯著低于外八字步態足第2～5趾骨(8.25±8.30)N·s、第2蹠骨(61.46 ±36.14)N·s(P＜0.05).結論 外八字步態足與正常步態足相比,足底壓力中心偏嚮足的內側,導緻蹬伸時的推進力不是直線嚮前,而是斜嚮的,行走方嚮上的蹬地效果較差；併且會在脛骨和腓骨之間產生一箇扭力,相應使脛骨齣現內翻,可能引起膝關節過度的摩抆,導緻損傷.

Objective To characterize the foot pressure distribution during walking of the male college students with a normal left foot and toes-out right foot gait.Methods Forty-two male college students age 20 to 25 with a toes-out gait on the right side and a normal gait on the left side were recruited.The FOOTSCAN system was used to measure their foot pressure distribution while walking.Results There were significant differences between the normal and the toes-out foot with regard to the peak pressure on the third metatarsal bone [(45.05 ±13.91)N/cm2 vs (26.83 ± 10.82) N/cm2] and pressure under the arch [(4.48 ± 1.94) N/cm2 vs (2.90 ±1.57) N/cm2],as well as the time for the appearance of peak pressure under the 1st and 4th metatarsal bones.The foot regional impulse was significantly lower on the normal side than on the toes-out side for toes 2 to 5 and for metatarsal bone 2.Conclusion In contrast to the normal foot,the pressure center of the toe-out foot deflects to the inner side.This results in slanted power application instead of straight ahead,so the strength in the direction of travel is small.And it will produce torsion between the tibia and fibula,which makes the tibia appear introverted and causes excessive friction in the knee joint.This will lead to injury of the knee joint.
