Surface electromyographic (EMG) recordings from the left and right masseteric areas during physical and psychological induced stress were obtained from 20 patients with mandibular dysfunction and 20 healthy controls. Integrated electromyographic activity was not significantly different for the two sides but was higher for patients than for controls during both stress and relaxation. Anxiety level, as measured with the Taylor Manifest Anxiety Scale, was higher for patients. Biofeedback treatment for the patients resulted in significantly reduced signs and symptoms of mandibular dysfunction. When the test procedures were repeated, the controls had not changed in their electromyographic responses during stress, whereas the patients showed a significant decrease in this respect. The results obtained are discussed in terms of a systems-oriented etiological concept.
对20名下颌功能紊乱患者和20名健康对照者在生理和心理诱导应激期间，记录左右咬肌区域的表面肌电图（EMG）。两侧的肌电图积分活动无显著差异，但在应激和放松期间，患者的该活动均高于对照者。用泰勒显性焦虑量表测量的焦虑水平，患者更高。对患者进行生物反馈治疗后，下颌功能紊乱的体征和症状明显减轻。当重复测试程序时，对照者在应激期间的肌电图反应没有变化，而患者在这方面则显著下降。从系统导向的病因学概念角度对所得结果进行了讨论。
