人行走时骨盆上下运动参数的模型分析
The Model Analysis of the Vertical Motion Parameters of the Pelvis during Human Walking
【摘要】 为了研究正常人行走过程中骨盆在垂直方向的运动特征,提出了一种以测量数据为基础建立骨盆运动参数数学模型的新思想。介绍了基于跑步机的骨盆运动轨迹测量系统,并对30名健康男性青年进行了获取骨盆运动参数的实验研究。实验结果得到了不同受试者分别以不同速度行走时的骨盆在垂直方向的多组运动轨迹,以及运动幅值、周期、初始相位等与行走速度和受试者身高的关系曲线。通过对曲线拟合,建立了各参数及骨盆运动轨迹的数学模型。通过对该模型进一步完善,可使其对康复评定、类人机器人等领域具有一定的应用价值。
【Abstract】 According to the various clinical factors affecting the motion parameters of the pelvis during human walking,a new method of model building was proposed based on the experimental findings.The treadmill-based measuring method of pelvis trajectory was introduced.An experiment on the vertical motion parameters of the pelvis for healthy male youth naturally walking on a treadmill was conducted.The mathematical model of the vertical motion parameters of the pelvis were deduced by fitting data through the least-squares procedure.These models could be used widely on computing the movement rule and related parameters of the pelvis for healthy male youth naturally walking ata arbitrary speed.It has practical significance in the fields including rehabilitation assess.
