To verify the characteristics of the electromyographic signal of masticatory muscles in individuals with TMD and asymptomatic individuals.
A systematic review was carried out, selecting cross-sectional studies with at least one electromyographic parameter (FM; iEMG; RMS) of the masticatory muscles (anterior temporal, bilateral masseter, and suprahyoid muscles) of individuals with TMD compared to asymptomatic individuals.
This review identified 1656 titles, of which 30 articles were included in the final analysis. It was observed that the data referring to the pattern of activation of masticatory muscles in the rest, isometry, and isotonic conditions of individuals with TMD are heterogeneous. This fact may be related to variability in the methods and analyses applied in the studies.
Data referring to the pattern of activation of masticatory muscles in the rest and isometry conditions and in the mastication cycle of individuals with TMD and asymptomatic individuals are diverse.
验证颞下颌关节紊乱病（TMD）患者与无症状个体咀嚼肌肌电信号的特征。
进行了一项系统评价，选择了横断面研究，比较TMD患者与无症状个体咀嚼肌（颞肌前部、双侧咬肌和舌骨上肌群）的至少一项肌电参数（FM；iEMG；RMS）。
该评价共识别出1656篇标题，最终分析纳入了30篇文章。观察到，关于TMD患者在静息、等长和等张条件下咀嚼肌激活模式的数据存在异质性。这一事实可能与研究中应用的方法和分析的变异性有关。
关于TMD患者与无症状个体在静息和等长条件下以及咀嚼周期中咀嚼肌激活模式的数据各不相同。
