拮抗肌对的自回归滑动平均模型的参数分析

将自回归滑动平均模型运用于肘关节桔抗肌对的肌电信号分析中，利用该模型所提供的丰富的参数，来研究在同一关节上的拮抗肌对的疲劳关系．模型中的一些自回归系数和肌疲劳程度具有相似的变化趋势．而且，对于同一伸展或屈曲过程，关节上的拮抗肌的疲劳参数要大于主动肌的参数．

Parameters Analysis of Elbow Antagonist Muscles with Autoregressive Moving Average Model

AREA parameters are represented by the coefficients of autoregtessive moving average model. Our last research work indicated that the muscle would fatigue under sustained contraction, and some of AREA parameters could reflect this fatigue feature with obviously decreasing tendency. In this paper, by analysing two groups of AREA parameters,the surface electromyograms(SEMG) from the flexor and extensor of nomal human elbow is processed and the fatigue relation between antagonist and agonist is shown. The parameters of the antagonist muscles are higher than those of the agonist, and both of them decline clearly at different rates as the contraction is sustained.
