Objective: This study aims to explore how shoes with different height heels affect female gait characteristics and motor function of lower limb joints. Methods: Video analysis and myoelectricity tester were applied to the walking test of 12 female models wearing shoes with 0, 3, 6, 10, and 18[Formula: see text]cm heels. Results: (1) When being barefoot and wearing the flat shoes, the models took a longest step, and the step length decreased with the increase of the shoe heel. (2) When walking in the flat shoes, the models kept the center of gravity highly stable. With the increase of the shoe heel, the center of gravity went ups and downs obviously in the direction of Z and Y when models were walking. (3) When models walked in the flat shoes, the smallest changes occurred in the hip joint angle. With the increase of the shoe heel, the stretching ranges of knee joint angle and ankle joint angle decreased. (4) When models walked in the flat shoes, electromyographic mean power frequency (MPF) indicated that active frequency of gastrocnemius and soleus were the highest and time-domain parameter suggested that active scope of biceps femoris and soleus increased most. There was difference in active frequency between the dominated leg and the nondominated leg. Conclusion: Flat shoes or 3–6[Formula: see text]cm heel shoes were the best for walking. It is recommended to choose shoes with a heel height higher than 10[Formula: see text]cm when walking,and try to control wear more than 10[Formula: see text]cm heel walking time, otherwise, there will be a risk of falls. When choosing a heel with a height higher than 10[Formula: see text]cm, the walking speed and walking length must be reduced. At the same time, try to control the walking time of wearing high heels with the heel height over 10[Formula: see text]cm, otherwise it will cause the risk of fall.

不同高度的鞋跟对年轻女性表演者下肢关节运动功能的影响

目的:本研究旨在探讨不同鞋跟高度的鞋子对女性步态特征和下肢关节运动功能的影响。方法:采用视频分析和肌电测试仪对12名穿着0、3、6、10、18[公式:见正文]cm鞋跟鞋的女模特进行步行测试。结果:(1)赤脚穿平底鞋时,模特走的步数最长,随着鞋跟的增加,步长减小。(2) 模特穿着平底鞋行走时,重心高度稳定。随着鞋跟的增加,模特行走时重心在Z、Y方向明显上下起伏。(3)模特穿着平底鞋行走时,髋关节角度变化最小。随着鞋跟的增加,膝关节角度和踝关节角度的拉伸幅度减小。(4)模型穿平底鞋行走时,肌电图平均功率频率(MPF)表明腓肠肌和比目鱼肌的活动频率最高,时域参数表明股二头肌和比目鱼肌的活动范围增加最多。支配腿和非支配腿之间的活动频率存在差异。结论:平底鞋或3-6[公式:见正文]cm鞋跟鞋最适合步行。走路时建议选择鞋跟高度高于10[公式:见文字]cm的鞋子,尽量控制穿在10[公式:见文字]cm以上的鞋跟走路时间,否则会有风险下降。选择高度高于10[公式:见文字]cm的鞋跟时,必须减少步行速度和步行长度。同时,尽量控制穿鞋跟高度超过10[公式:见正文]cm的高跟鞋的步行时间,否则有摔倒的危险。
