Evaluation of viscoelastic property of leg and shoes using accelerometer

本研究采用加速度计设计了行走和跑步过程中腿部着地冲击和加速度的测量系统。在此基础上，研究了行走和转弯运动中腿部运动变化对踝关节动力学的影响，以及切割运动中跑步速度、转弯方向和足部位置变化对腿部运动和负荷的影响。同时，通过穿着改变鞋垫粘弹性的鞋子，测量足部稳定性、腿部肌肉活动、着地冲击力和行走时腿部加速度。

In this study, the measurement system of landing impact and acceleration on the leg during walking and running was developed using accelerometer. Then it was examined that the influence of changing leg motion on kinetics of the ankle joint during walking and turning motion, and the influence of changing running speed, direction of turn and foot position during cutting movement on motion and load of the leg. Also, the stability of foot, muscle activities of the leg, landing impact and acceleration of the leg during walking were measured while wearing shoes that changing viscoelastic property of insole.
