“…Surface electromyography (sEMG) is a noninvasive technique used to analyze the function of the masticatory muscles which, being located in a superficial position, are easily accessible using surface electrodes [14,15]. This exam is painless and innocuous [16].…”

Objective: To investigate the action of osteopathic manipulative treatment on the muscular activity of the stomatognathic apparatus by using surface electromyography (sEMG). Material and Methods: Surface electromyography (sEMG) was performed on the masseter and anterior temporalis muscles of 120 subjects (73 F; 47 M), both at time T0 and T2. The sample was divided into three randomized groups of 40 subjects each: control, placebo, and osteopathic manipulative treatment (OMT). In the T1 interval between the two evaluations, the control group was not treated, the placebo group underwent a placebo treatment, and the OMT group underwent manipulative treatment. The mean value of each measurement and its coefficient of variation, between time T0 and T2, were calculated for both the intragroup (OMT, placebo, control) and the intergroup (OMT-placebo, OMT-control). Outcomes: In 40% of the subjects, statistically significant improvements were highlighted in the OMT. Whereas, the statistically significant results of the placebo and control groups were 7.5% and 17.5%, respectively, of which more than 75% moved away from the physiological range, showing a worsening of the muscular activity. This analysis showed statistically significant variations (p ≤ 0.05) in the OMT group compared to the placebo and the control groups. Conclusions: OMT determines variations of the activity of masticatory muscles.

“…To date, information regarding masticatory muscle EMG activity in TMD children and adolescents is limited [26,27,35]. Early electromyographic analysis of the masticatory muscles in such patients with TMD problems is important for a better understanding of TMD neuromuscular characteristics in this age group and could ensure simpler and improved treatment procedures aimed at addressing muscle involvement in TMD and prevent chronic muscle/joint dysfunction in adulthood [26].…”

“…In the next part of the examination, electromyographic recordings with a DAB-Bluetooth Instrument (Zebris Medical GmbH, Germany) were taken for all the study subjects by a single experienced examiner. The protocol followed here has already been described by us in previous papers [ 27 , 28 , 38 ].…”

“…Surface electromyography (sEMG) is widely applied as an additional noninvasive tool for assessing patients with TMD as well as for observing the electrophysiological behaviour of muscles under a variety of physiological conditions [19][20][21][22][23][24][25]. Due to the simplicity of this method and its safety and availability, it has also been used in studies on children [26][27][28]. An EMG evaluation of masticatory muscle function in TMD subjects provides a basis for diagnosing the disease, monitoring its progression and measuring the effectiveness of treatment.…”

“…To the authors' knowledge, only a few studies have been conducted on masticatory muscle function in the children with TMD [26,27,35]. As a consequence, research on the electromyographical activity of the masticatory muscles in such subjects with TMD problems is needed.…”

Aim. The aim of this study was to evaluate masticatory muscle electrical activity in patients with pain-related and pain-free temporomandibular disorders (TMDs) as well as in subjects with no TMD. Methods. Ninety children with mixed dentition were recruited to the study. Of this total, 30 subjects were diagnosed with pain-related TMD (TMD-P), 30 with pain-free TMD (TMD-PF), 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). Results. An analysis of the EMG recordings showed statistically significant intergroup differences in masticatory muscle electrical activity at rest and during MVC. Significantly higher rest temporalis muscle activity was noted in pain-related TMD subjects compared with that children from the pain-free TMD and non-TMD groups, as well as in TMD-PF children in relation to those without TMD. The EMG potentials of the temporalis muscle during MVC were much lower in patients with TMD-P than in pain-free TMD and non-TMD subjects. Masseter muscle activity at rest in the TMD-pain group was significantly greater, and masseter muscle EMG potentials during clenching were markedly lower than in patients with no TMD diagnosis. Conclusion. The use of electromyography to assess masticatory muscle function revealed alterations in the pattern of temporalis and masseter muscle activity in patients with pain-related TMD compared with the pain-free subjects.
