The power spectral distribution of an electromyogram offers a useful presentation of the myoelectric signal at any level of muscle activity. Various factors which may affect this distribution are considered. A computerized method for obtaining the power spectral distribution for masseter and a study of the effect of bite force and electrode position on this is described.
肌电图的功率谱分布为肌肉活动在任何水平下的肌电信号提供了一种有用的呈现方式。文中考虑了可能影响这种分布的各种因素。描述了一种用于获取咬肌功率谱分布的计算机化方法,以及咬合力和电极位置对其影响的研究。
