|
Abstract:
本文通过建立步态模型并结合试验验证，研究在水平步道行走受扰发生滑移后，滑动腿足跟接触步道时刻至非滑动腿足跟接触步道时刻内人体下肢髋关节、膝关节和踝关节运动的力学效应。本文募集10名健康青年男性受试者进行试验，采集分析了在油面步道环境行走时发生滑移后自主恢复平衡和滑倒两种情况下的人体下肢关节角度和关节力矩变化规律。综合步态模型和步态试验，对人体发生滑跌过程中下肢关节力矩和关节角度变化趋势和机理作了详细的研究和分析。本文的研究成果为人体避免滑跌损伤和下肢助行装置及康复辅具的开发设计提供了科学的理论支撑。
In this paper, a human gait model was established and validated by experiments. Mechanical effects of hip joint, knee joint and ankle joint in human lower limb from sliding leg heel contacting trail to non-slip leg heel contacting trail were studied, when the human body walked on the horizontal footpath and disturbed to slipping. A total of 10 healthy young male volunteers were enrolled in the trail, collected and analyzed the changes in joint angles and joint torques of the lower limbs of the human body under two conditions: autonomous recovery of balance after slipping and slipping during walking in the oil surface trail environment. Combining the gait model and trail, the trend and mechanism of joint torque and joint angle of lower limb during sliding process were studied and analyzed in detail. The research findings could provide a scientific theory to support the development of avoiding injury for slipping and designing of devices lower limb working aids and rehabilitation aids.
