Research On The Semg Characteristics Of Young Women’s Lower Limb Who Wear High Heels

In modern society, high-heeled shoes become the daily necessities of women. However, the design of high-heeled shoes go against with the human body’s motive and mechanics principles. With the increasing of the heel-height, people heels will be lifted. As a result, the plantar pressure are redistribute, the force situation of lower limb muscles and skeletal musculature are different with flats. Wearing high heels can cause a lot of damage, such as unusual deformation toe, feet deformed, ankle injuries, gonitis and muscle injury. Previous studies of high heeled shoes mainly concentrated on gait, plantar pressure and joint angle. However, there are few papers on the influence of high heeled shoes on young women’s lower limb muscles SEMG have been published in this field. To analyze the impact of high heeled shoes on young women’s lower limb muscles SEMG is necessary.9young females were chosen for the test. Four heel-height shoes were choosen as the experimental shoes. The test actions are standing to squating, squaring to standing, standing to sitting, sitting to standing, free walk, upstairs, downstairs. JE-TB0810myo-electric acquisition system were chosen as the testing equipment. Statistical analysis was carried out on the experimental data with SPSS20.0software, including normal distribution test, paired sample T test.Based on the experimental data, the results show that:(1)Young females lower limb muscles is left-right symmetric;The same muscles’motion contribution in different test action are different. When performing the same action in four kind of heel height, the sequencing of muscle’s magnitude order is different. Comparing the same muscle in same action in four kind of heel height, the motion contribution of thigh muscle except biceps femories showed a rising trend with the increase of heel height while the motion contribution of calf muscle except soleus decline.In this article, analyze the lower limb muscles electromyography when young women complete daily life activities, provide the basis for designing, selection of high heels.
