Objective To study the effect of different high-heel shoes on the gait of young females and provide some theoretical basis in quantity scientifically the design of the high-heel shoes.Methods Normal digital video camera and footscanUSB system were combined and the gaits of 10 young women(average age is 19.2 .42) walking on the flat ground with normal speed with barefoot and wearing four pairs of varying high-heel shoes were tested in order to make comparative analysis on their kinematic and kinetic parameters.Results(1) when the heel height of shoes increases,the stride velocity,the stride length,the stride frequency and the joint angles of the lower limb grow smaller in order to obtain the safe and stable gait;(2) the higher the shoe heel,the larger Percentage of support phase and double support phase accounting for gait cycle,the smaller Percentage of swing accounting for gait cycle;(3) the value of the peak force of forefoot,the percentage of impulse on the forefoot and mid-foot become larger,when the subjects walk wearing the higher heel shoes.(4) The thickness of shoes heel also influences the gait characteristics.Conclusion Walking with the high-heel shoes could cause the foot fatigue,pain and injuries easily or the abnormality of foot growth.
