In order to analyze the lower limb biomechanical characteristics of healthy young men's gait initiation,BTS-SMARTDX motion capture system was used to test,and the changes in muscle strength were simulated via OpenSim.After discussion,gait2392 model can accurately simulate the starting gait of healthy young men.In the Anticipatory Postural Adjustments phase,dorsiflexion of the ankle with knee flexion,and the hip joint of the initiating side is abducted;the ankle dorsiflexors of the supporting side and the hip abductors of the initiating side co-ordinate with each other to complete the task of loading the initiating side and unloading the supporting side;In the foot lift phase,the knee joint flexion is the leading part to drive the lower limb movement,the plantar flexor performs the pedal extension function.In the execution phase,the knee joint is extended as the dominant swing forward,and the rectus femoris performs double functions of hip flexion and knee extension.The present results can help the design and study on the lower limb power assisted exoskeleton.
