Background Temporomandibular disorder (TMD) development in fibromyalgia syndrome (FMS) is not yet fully understood, but altered neuromuscular control in FMS may play a role in triggering TMD. Objective The purpose of this study was to verify the association between neuromuscular control and chronic facial pain in groups of patients with FMS and TMD. Design A cross-sectional study was conducted. Methods This study involved an analysis of facial pain and electromyographic activity of the masticatory muscles in patients with FMS (n=27) and TMD (n=28). All participants were evaluated according to Research Diagnostic Criteria for Temporomandibular Disorders and surface electromyography (SEMG). Myoelectric signal calculations were performed using the root mean square and median frequency of signals. Results The data revealed premature interruption of masticatory muscle contraction in both patient groups, but a significant correlation also was found between higher median frequency values and increased facial pain. This correlation probably was related to FMS because it was not found in patients with TMD only. Facial pain and increased SEMG activity during mandibular rest also were positively correlated. Limitations Temporal conclusions cannot be drawn from the study. Also, the study lacked a comparison group of patients with FMS without TMD as well as a control group of individuals who were healthy. Conclusions Altered neuromuscular control in masticatory muscles may be correlated with perceived facial pain in patients with FMS.

Level Of Significance

Rest position of the infants' tongue with and without lingual frenulum alteration is poorly reported in the literature. The present study aims to verify the rest position of the tongue in infants with and without lingual frenulum alteration. A cross-sectional study was conducted with 324 infants. While the infant was sleeping, deep sleep, the SLP, facing the baby, opened the infant's mouth by pushing down the infant's chin with their thumbs, and at the same time, elevated the upper lip using their index fingers. The maneuver provided the visualization of the infant's tongue position at rest: elevated or down. The Chi-square test was used for statistical treatment of the data at 5% level of significance (p<0.05). The variables included in the Chi-square analyses were: a) tongue elevated, b) tongue down-positioned, c) normal lingual frenulum, and d) altered lingual frenulum. The statistical analysis demonstrated that there was an association between the tongue position at rest and the characteristics of the lingual frenulum. When the lingual frenulum was altered, the infant's tongue rest position tended to be down in the oral cavity (p<0.001). In infants with lingual frenulum alteration, the tongue at rest tended to be down-positioned, between the gum pads. In infants with normal lingual frenulum, the tongue at rest tended to be elevated.

Masseter Muscles

Temporomandibular disorders (TMD) are manifested as a group of signs and symptoms that affect a particular population profile. Some variables such as sex and age influence the clinical expression of this condition. This observational descriptive cross-sectional study aimed to correlate the severity of TMD established by the craniomandibular index (CMI) with the variables: age, sex and electromyographic activity of the masseter and anterior temporal muscles. Fifty-four subjects (15 males/39 females) aged between 16 to 65 years (mean age = 41 years) and diagnosed with TMD were evaluated. Severity was determined by the CMI. These subjects also underwent examination by surface electromyography of the masseter and anterior temporal muscles. No correlation was found between age and severity of TMD (p=0.19/r=0.16), however there was a trend of greater severity in young adults (25-50 years). The sex variable in the correlation was positive with the CMI (p=0.03/r=-0.96) and superior to women. A greater EMG activity of the anterior temporal in relation to masseter (p=0.01) was found and the left temporal activity had the highest average (161.5 ± 44.6 Hz). The electromyographic activity of the anterior temporal and right masseter muscles was positively correlated with the Dysfunction Index CMI (p=0.01). The use of CMI to quantify the severity of TMD and of EMG to assess the functionality of the masticatory muscles can be important allies to direct the treatment.
