Electromyograms (EMGs) from the corrugator, zygomatic and splenius capitis muscle sites and Beck depression inventory scores were obtained from 21 depressed in-patients shortly after admission and after two weeks in hospital. Contrary to the result of a previous study by other investigators, significant covariaton between depressive symptoms and corrugator EMG levels was not seen. However, consistent with a second finding of the previous study, initial corrugator EMG levels were shown to be significantly predictive of treatment outcome. Further, initial EMG from the zygomatic was also found to predict changes in depression. The explanation is unclear and further research is needed.
从21名住院抑郁症患者入院后不久及住院两周后获取了皱眉肌、颧肌和头夹肌部位的肌电图（EMG）以及贝克抑郁量表评分。与其他研究者之前的一项研究结果相反，未发现抑郁症状与皱眉肌肌电图水平之间存在显著的协变关系。然而，与之前研究的第二个发现一致，初始皱眉肌肌电图水平被证明对治疗结果具有显著的预测作用。此外，还发现初始颧肌肌电图也能预测抑郁的变化。其原因尚不清楚，需要进一步研究。
