步态自主平衡行为的下肢神经肌肉力学分析

Analysis of Neuromuscular Mechanics of Lower Extremities Based on Self-Balance Recovery During Walking

针对步态过程滑移后的自主平衡恢复行为,建立了基于神经肌肉力学理论的下肢行走多杆动力学模型.利用该模型对步态滑移现象发生后的自主平衡恢复过程进行了定性分析,给出了步态自主平衡恢复行为中的主控参数,并对自主平衡恢复过程中下肢肌群的功效进行了讨论,计算了自主平衡恢复行为中的下肢肌群主控参数.两组不同受试者的滑后自主平衡恢复实验结果表明,该步态模型可用于分析滑跌后的自主平衡行为特征.

Aiming at the self-balancing recovery of post-slip during adults＇ walking, a multi-rod dynamic lower ex- tremity gait model was proposed that could make a qualitative analysis of self-balance recovery of post-slip during walking. Using this model, the main and independent parameters and the leading muscle actions of lower extremity were discussed. The experimental results of self-balance during post-slip about two different groups show that the model is able to be used to analyze the muscle actions about self-balance during post-slip.
