“…A presença de hiperatividade é considerada quando a elétrica muscular apresenta-se com valor superior a 5 microvolts 11 . Neste estudo, os múscu-los trapézio superior direito e esquerdo mostraram-se hiperativos, o que pode ser atribuído ao fato de que o músculo trapézio é sistematicamente recrutado para produzir estabilidade do pescoço e pode ser ativado por reflexos nociceptivos presentes em mecanismos protetores 24 . Ao avaliar 38 indivíduos com DTM miogênica, Pallegama et al 25 verificaram aumento na atividade elétrica de repouso relacionada à presença de dor nos músculos ECOM e trapézio nesses indivíduos quando comparados a controles.…”

A DTM foi diagnosticada pelo critério de diagnóstico em pesquisa para DTM (Research Diagnostic Criteria for Temporomandibular Disorders). A eletromiografia dos músculos esternocleidomastoídeo (ECOM) e trapézio superior foi realizada bilateralmente, na situação de repouso, com frequência de 2 KHz e filtro passa-faixa de 10-1000 Hz. As medidas de ADM de flexão, extensão, lateroflexão e rotação foram realizadas com um flexímetro e a comparação entre os grupos contou com o teste de Mann Whitney. O teste de Spearman foi aplicado para a correlação entre as variáveis, com nível de significância de 5%. Não foi verificada nenhuma diferença na ADM cervical entre os grupos. A atividade elétrica demonstrou-se significativamente maior nos músculos ECOM direito (p=0,0130), trapézio superior direito (p=0,0334) e esquerdo (p=0,0335) no grupo DTM em relação ao grupo controle. Não houve correlação significante entre atividade elétrica e ADM cervical. A dor nos músculos cervicais apresentou-se significativamente maior apenas no músculo ECOM direito (p=0,0055). Conclui-se que os grupos estudados registraram diferença na atividade elétrica dos músculos cervicais, sendo esta maior em indivíduos com DTM. DEScRitORES: transtornos da articulação temporomandibular; eletromiografia; amplitude de movimento articular.ABStRAct: The aim of the research was to evaluate the electrical activity and pain on palpation of the cervical muscles, the cervical range of motion (ROM) and the relationship between electrical activity and ROM in individuals with and without temporomandibular disorder (TMD). Fifty three volunteers took part in the study, being 24 with TMD and 29 without, both genders, from 18 to 32 years old. The TMD was diagnosed through Research Diagnostic Criteria for Temporomandibular Disorder (RDC/TMD). The electromyografhy of Sternocleidomastoideus (SCM) and upper trapezius muscles was carried out bilaterally during rest situation, with a frequency of 2 KHz and band-pass filter of 10-1000Hz. The measures of flexion, extension, lateral tilt and rotation ROM were acquired through a fleximeter and the comparison between groups was analyzed by Mann-Whitney test. The Spearman test verified the correlation between the variables, with 5% of significance level. There were no differences in the cervical ROM between the groups. The electrical activity was significantly higher in the right SCM (p=0,0130), left (p=0,0335) and right (p=0,0334) trapezius muscles in the TMD group. There were no significant correlations between electrical activity and cervical ROM. Pain in the neck muscles was significantly higher only in the right SCM (p=0,0055). It is concluded that the studied groups had difference in the electrical activity of the cervical muscles, which was larger in the individuals with TMD.

“…This phenomenon may be related to the close connection of masticatory muscles and neck muscles, which form a functional whole by maintaining the balance and stabilization of the head [9]. The lack of balance between these structures can lead to changes in the resting position of muscles and, as a result, to muscle hyperactivity [10].…”

Introduction. Pathological muscle tone can cause changes in the facial skeleton, including tension headaches, tinnitus, temporomandibular joint dysfunctions. The complexity of pathologies and their spectrum may also indicate changes beyond the facial skeleton. The aim of the study was to determine the possible correlation between the pressure pain threshold of the trapezius muscle and the bioelectrical tension on the masticatory muscles. Aim. The aim of the study was to determine the possible correlation between the pressure pain threshold of the trapezius muscle and the bioelectric tension on the masticatory muscles. Material and methods. The number of 36 women applied for the study. They were all examined using an algometer within a trapezius muscle to determine the pressure pain threshold. The electromyographic study was carried out in accordance with the SENIAM guidelines. The resting activity of selected masticatory muscles (temporal and masseter) was recorded for 10 sec. The study involved an 8-channel BioEMG IIITM surface electromyography apparatus with BioPak Measurement System (BioResearch Associates, Inc. Milwaukee, WI, USA). Statistical analysis was carried out using the r-Pearson test. The level of significance was set at 5%. Results. After comparing the bioelectric tension of the masticatory muscles and the pressure pain threshold, left-sided correlation was observed (p<0.05). Both in the right-hand and general comparison, the results did not reach the required level of statistical significance (p>0.05). Conclusions. The pressure pain threshold seems to be linked to the bioelectrical muscle tone of the masticatory muscles. To confirm this observation, further research into a larger and more diverse group of participants is recommended.

Research background. The imbalance between the jaw and neck muscle activityoccurs as a compensatory mechanism in order to stabilize the jaw and neckstructural parts in temporomandibular joint (TMJ) disorders (Ries et al., 2008).Changes occur in posture control system if any biomechanical unit varies (Ritzel et al., 2007). One system compensates the unusually active other body system in upper cross syndrome (UCS) (Tharcher et al., 2011). This syndrome is characterized by shortened upper trapezius, pectoralis major and romboids and week middle and lower trapezius, serratus anterior and deep neck flexors (Moore, 2004; Tharcher et al., 2011). Thus, it is believed that there may be a direct link between the uppercross syndrome and temporomandibular joint dysfunction.Purpose. Explore relationship between temporomandibular joint dysfunctionand upper crossed syndrome in women.Methods. Thirty female volunteers participated in the study, and they weredivided into groups according to trigger points in the shoulder and neck muscles:group 1 – painful shoulder and neck muscles (32.65 ± 12.34 years), group 2 –painless shoulder and neck muscles (34.5 ± 10.95 years). Survey was carriedout assessing TMJ function during observation, palpation, evaluation of the sagittalcraniovertebral angle, the neck and shoulder muscle length, strength, pain anddeep neck muscle endurance was examined.Results. It was found that TMJ function was strongly associated with the UCS:trapezius pain as well as upper trapezius and scalenus length. TMJ disorders wereassociated with headache in both groups. Weak connection between deep neckmuscle endurance and TMJ dysfunction was identified.Conclusions. TMJ mobility is partly related to UCS, and TMJ functional disordersrelated to headache and sagittal craniovertebral angle. UCS specific changes,such as pectoralis muscle length changes and impaired deep neck muscle endurance are not related to TMJ dysfunction.
