| 摘 要： | 目的:探讨手臂摆动对人体行走步态特征的影响,从而为无臂的仿人机器人以及假肢的设计提供理论支持. 方法:选用10名青年男性大学生为受试者,以1. 5 ± 0. 3m/s的速度完成手臂自然摆动和限制双臂摆动的行走运动,研究采用Kistler三维测力台、Motion红外高速运动捕捉系统同步采集受试者行走时动力学和运动学数据. 结果:(1)限制摆臂会显著降低步行频率;(2)限制摆臂会显著增大步行时重心的上下摆动、减少骨盆的旋转角度;(3)踝关节的生物力学参数在两种不同运动状态下表现出显著性差异,不摆臂时踝关节屈伸角度增大、屈伸力矩增大、关节做功增大;同时,不摆臂会造成膝伸力矩显著性增大,做功增多;针对髋关节,不摆臂会造成髋关节的屈伸角度增大;(4)下肢各参数在两种走路模式上表现出高度的相关性. 结论:步行中手臂自然摆动可以降低腿部的能量消耗,是节省能量的一种行走模式;摆臂与不摆臂两种行走状态下肢的运动模式在不同水平上高度一致.

| Abstract: | Objective:This study explores the effects of arm wing restraint on walking patterns so as to provide theoret-ical support for the design of no-arm human-simulation robots and prosthetic devices. Methods:Choosing ten young male students as subjects and asking them to walk at the speed of 1. 5﹢ -0. 3m/s while swinging their arms naturally and walking with their arms restrained respectively. Using Kistler's 3D force platform and the in-frared high-speed motion capture system to collect subjects' kinetic and kinematic data. Results: (1) Arms swing restraint will significantly reduce the walking frequency; ( 2 ) arm swing restraint will dramatically in-crease the vertical range of gravity movement and the rotary angle of pelvis;(3) under the two different motion conditions, biomechanic parameters present significant differentiation; ( 4 ) under the two walking patterns, lower limb parameters are highly correlated (r>0,90) . Conclusion: Arm swing during walking will reduce legs' energy consumption. Therefore it is a kind of energy-saving walking pattern. The motion pattern of lower limbs under the two walking conditions is highly identical. |
