摘要
探讨如何利用针电极肌电信号来评价人体的肌肉疲劳。采用参数化模型的方法提取针电极肌电信号的AR模型a1参数,并对反映肌肉疲劳时间过程的a1参数进行直线拟合。实验结果发现拟合的直线变化趋势能够较好地反映肌肉的疲劳过程。
It is discussed how to evaluate muscle weariness by NEMG in the thesis.So are to abstract AR model a_1 parameter of NEMG by parameterized model and to fit straight line the a_1parameter reflecting the time process of muscle weariness.Findings of the experiment show that the trend of the fitted straight line reflects quite well the muscle weariness process.
