简要总结
The aim of this study was to evaluate masticatory muscle electrical activity in patients with pain-related and pain-free temporomandibular disorders (TMD) as well as in subjects with no TMD. Ninety children with mixed dentition were recruited to the study. Of this total, 30 subjects were diagnosed with pain-related TMD, 30 with pain-free TMD, and 30 without TMD. We used Axis I of the Research Diagnostic Criteria for TMD (RDC/TMD) to assess the presence of TMD in the examined children. The electromyographical (EMG) potentials of the temporalis and masseter muscles were measured with a DAB-Bluetooth Instrument (Zebris Medical GmbH, Germany) at rest and during maximum voluntary clenching (MVC).

结局指标
主要结局
Electromyographic analysis of the masticatory muscles in patients with pain-related temporomandibular disorders
时间窗: For a single subject the whole EMG examination was taken 40 minutes.
A DAB-Bluetooth Instrument (Zebris Medical GmbH, Germany) was used to take electromyographical (EMG) recordings of the temporalis and masseter muscles at rest and during maximum voluntary contraction (MVC).Disposable, self-adhesive Ag/AgCl bipolar surface electrodes were placed at a fixed inter-electrode distance of 20 mm on the anterior temporal muscles and on the superficial masseter muscles parallel to the muscular fibres. The EMG signals were amplified, digitized and digitally filtered. The EMG results were analysed using the Student t-test, analysis of variance (ANOVA) and a Student-Newman-Keuls post-hoc test.
