Localized muscle fatigue in the masseter muscle was studied with a method based on power spectrum analysis of myoelectric signals. Under the influence of fatiguing contractions, a gradual shift of the spectral curve occurred; the rate of change was taken as a measure of the development of fatigue. The fatigue was dependent on the bite force. The existence of a threshold value of force, below which significant myoelectric fatigue changes do not develop, was shown.
采用基于肌电信号功率谱分析的方法，对咬肌局部肌肉疲劳进行了研究。在疲劳收缩的影响下，频谱曲线逐渐发生偏移；将变化率作为疲劳发展程度的度量。疲劳程度取决于咬合力。研究表明存在一个力的阈值，低于该阈值不会发生明显的肌电疲劳变化。
