【摘要】：如今高跟鞋作为大多数女性的选择,逐渐成为了女性生活中不可缺少的部分,同时它也是影响女性身体健康的重要因素之一。本文研究首次同时运用三维录像解析系统、肌电测试系统及三维测力台系统对女性穿7cm高跟鞋和平底鞋行走进行同步测试,并得出以下结果:(1)运动学分析显示,足跟着地时刻,足全脚掌着地时刻以及足跟离地时刻,穿7cm高跟鞋会导致髋关节角和膝关节角减小,踝关节角增大。足趾离地时刻,穿7cm高跟鞋此时髋关节角有所减小,而膝关节角和踝关节角有所增加。支撑初期,穿7cm高跟鞋步速较慢,所用时间为0.13秒。穿7cm高跟鞋髋关节角增加,膝关节角和踝关节角都有减小。支撑中期,穿7cm高跟鞋步速明显较慢,所用时间是整个支撑阶段最多的为0.44秒,主要由膝关节过分屈曲造成。穿7cm高跟鞋踝关节角和髋关节角都减小,但膝关节角却有增加。支撑后期,穿7cm高跟鞋步速较慢,所用时间为0.14秒。穿7cm高跟鞋膝关节角减小,踝关节角和髋关节角整体都增加。(2)肌电分析显示,支撑初期和支撑中期穿7cm高跟鞋左脚的胫骨前肌、腓肠肌外侧肌的平均积分肌电值分别为:39.75 u Vs、37.85u Vs和56.33u Vs、52.67u Vs。支撑初期和支撑中期这两块肌肉肌电活动都较强,特别是支撑中期肌电活动非常激烈,平均积分肌电值是整个支撑阶段中最大的,同时胫骨前肌、腓肠肌外侧肌平均肌肉振幅百分比也大于穿平底鞋,因此,这两个阶段容易造成小腿肌肉疲劳,导致小腿酸痛。支撑后期,穿7cm高跟鞋左脚的胫骨前肌和腓肠肌外侧平均积分机电值小于穿平底鞋,原因是穿7cm高跟鞋行走时,在支撑后期,踝关节始终处于屈的状态对腓肠肌的预拉长减小,导致肌腱力臂减短,减小了蹬伸阶段的能力。(3)动力学分析显示,穿7cm高跟鞋垂直方向力在足跟完全着时刻前出现两次波动,说明在足跟刚接触地面到足跟完全着时刻,穿7cm高跟鞋在垂直方向不稳定。穿7cm高跟鞋在足跟着地时刻、足全脚掌着地时刻和足趾离地时刻,X方向和Y方向上晃动较大。在Z方向上,在足跟着地时刻,出现了一极大值为6806.18N,此刻力值是最大的。在足全脚掌着地时刻,在Z方向上,受力达到最小为4436.54N。在足趾离地时刻,出现了又一极大值为6390.82 N,但小于足跟着地时刻的力值。左脚足全脚掌时刻在X方向上和Y方向上晃动是最小。而X方向上和Y方向上晃动最大是在左脚足跟着地时刻左脚足趾离地时刻。
[Abstract]:Nowadays, as the choice of most women, high heels have gradually become an indispensable part of women's life, and it is also one of the important factors affecting the health of women. In this paper, for the first time, three dimensional video analysis system, myoelectric testing system and three dimensional dynamometer system are used to simultaneously test women walking in 7cm high heels and flat shoes, and the following results are obtained: (1) Kinematics analysis shows that: (1) Kinematics analysis shows that: 1. At the time of foot following, the moment of full foot landing and the moment of heel leaving the ground, wearing 7cm high heels will result in the decrease of hip joint angle and knee joint angle, and the increase of ankle joint angle. The angle of hip joint decreased, while the angle of knee joint and ankle joint increased. In the early stage of support, the walking speed of wearing 7cm high heels is slow, and the time is 0. 13 seconds. The angle of hip joint increased, the angle of knee joint and ankle joint decreased. In the middle stage of support, the walking speed of wearing 7cm high heels was obviously slower, and the time used was the maximum of 0.44 seconds in the whole support stage, which was mainly caused by the excessive flexion of the knee joint. The ankle angle and hip angle in 7cm heels decreased, but the knee joint angle increased. In the later stage of support, the speed of walking in 7cm heels is slow, and the time is 0. 14 seconds. The knee angle of wearing 7cm heels decreased, and the ankle angle and hip angle increased. (2) Electromyographic analysis showed that the anterior tibia muscle of the left foot of 7cm high heels was worn in the early and middle stages of support. The mean integral myoelectric values of the lateral gastrocnemius muscle were 39.75 u Vs,37.85u Vs and 56.33 u Vs,52.67u Vs., respectively. The myoelectric activity of the two muscles was strong in the early and middle stages of support, especially in the middle period of support. The mean integral myoelectric value was the largest in the whole support period, and the tibial anterior muscle was also the largest. The average muscle amplitude percentage of the lateral gastrocnemius muscle is also higher than that of wearing flat shoes. At the later stage of support, the average integral electromechanical value of the anterior tibial muscle and the gastrocnemius muscle in the left foot of the 7cm heels was lower than that in the flat shoe. The reason was that when walking with 7cm high heels, the ankle was always in the flexion state and the prestretching of the gastrocnemius muscle decreased during the later supporting period. As a result, the tendon arm is shortened and the ability to push and extend is reduced. (3) dynamic analysis shows that the vertical force in the 7cm stilettos fluctuates twice before the heel is fully on the heel, indicating that the heel has just touched the ground from the heel to the full heel landing. Wearing 7cm heels is not stable in the vertical direction. Wear 7cm heels in the heel of the foot, foot on the soles of the moment and the toe off the ground, X direction and Y direction shaking larger. In the Z direction, a maximum of 6806.18N appears at the foot following moment, and the force is the largest at this moment. When the foot is on the ground on the soles of the foot, in the Z direction, the minimum force is 4436.54N. Another maximum is 6390.82 N, but less than the force value at the foot following moment at the time when the toe is off the ground. The left foot's full soles are minimum in X and Y directions. The maximum sloshing in X and Y direction is at the moment when left foot follows the left toe.
