Background: Temporomandibular disorder (TMD) is a set of disorders involving the masticatory muscles, the temporomandibular joint (TMJ) and/or the associated structures. Objectives: To evaluate the occurrence of cervical and scapular instability in subjects with TMD. Methods: A total of 22 patients participated in the study, being 11 of them with TMD, selected using the RDC/TMD criteria, and 11 in the control group. The stabilization capacity of the neck muscles was evaluated through StabilizerTM and the muscles of the shoulder girdle through specific tests. Cervical mobility data from both groups were provided using the accelerometer while for cervical disability was used the Neck Disability Index (NDI) questionnaire. Results: Cervical instability was higher in the TMD group (20.36 ± 3.2) than in the control group (28.54 ± 0.8), revealing significant difference (p= 0.03). The highest percentages of scapular stabilization tests were found in subjects with TMD, (n= 9; 81.81%) when compared with control subjects (n= 5; 45.45%). The NDI results showed that the TMD group presented mild cervical incapacity (11.18 ± 2) and the control presented no disability (2.27 ± 0.4; p= 0.001). Conclusion: Cervical disability, and cervical and scapular instability were more frequent in subjects with TMD.
Excessive masticatory muscle activity is generally present in awake bruxism, which is related to increased anxiety and stress. It has been hypothesized that biofeedback could potentially manage awake bruxism, however, its effectiveness has not been empirically analyzed in a systematic manner. Therefore, this systematic review was designed to determine the effectiveness of biofeedback compared to other therapies in adults with awake bruxism. Extensive searches in five databases looking for randomized controlled trials (RCTs) that included biofeedback to manage awake bruxism were targeted. The risk of bias (RoB) assessment was conducted using the Cochrane RoB-2 tool. Overall, four studies were included in this systematic review, all of which used the electromyographic activity of the masticatory muscles during the day and night as the main endpoint. Auditory and visual biofeedback could reduce the excessive level of masticatory muscle activity in a few days of intervention. The majority of the included studies had a high RoB and only one study had a low RoB. The standardization of the biofeedback protocols was also inconsistent, which makes it difficult to establish the ideal protocol for the use of biofeedback in awake bruxism. Thus, it is proposed that future studies seek to reduce methodological risks and obtain more robust samples.
Objetivo: Verificar o desempenho de um aplicativo gamificado móvel com biofeedback eletromiográfico no registro de atividade mastigatória e da deglutição em idosos. Método: Trata-se de estudo piloto, em que foram avaliados 15 idosos, sendo adotado como critério de exclusão: ter comprometimento cognitivo, avaliado pelo item 2.7 da caderneta de saúde da pessoa idosa, ser desdentado em ambos os arcos dentários e/ou não possuir dentes molares. Utilizou-se um equipamento eletromiográfico associado a um jogo virtual para smartphones e tablets, que registrou as atividades do músculo masseter e supra-hioideos bilateralmente, via bluetooth. Resultados: O valor médio de força de mordida para o masseter do lado direito foi de: 227 ± 23,4 (μV), e esquerdo de 213 ±32,4 (μV). Para a musculatura supra-hioidea o valor médio do lado direito foi de 216 ± 36,1 (μV), e esquerdo de 208 ± 43,9 (μV). Conclusão: Verificou-se que o equipamento associado ao aplicativo é capaz de captar as contrações e decodificar os sinais eletromiográficos, e por ser de baixocusto e de fácil manuseio, poderá contribuir na terapêutica mastigatória e da deglutição de idosos.

Aim: the purpose of this review is to evaluate the effect of lower limb neuromotor exercises on static and dynamic balance in basketball players. Methods: the search strategy was carried out in the following databases: Medline/Pubmed, LILACS, Scopus, and PEDRO. Certainty of evidence was assessed by GRADE for posteromedial, posterolateral, and anterior directions, and composite score of the Star Excursion Balance Test. Results: the initial search identified 520 studies. Of them, six studies were included in this review, and three of them were included in the meta-analysis (n = 64). GRADE evaluation indicated low level of certainty of evidence for posteromedial (MD = 4.92%; 95% CI = -1.44 to 11.29; P = 0.13; I2 = 55%), posterolateral (MD = 6.08%; 95% CI = 2.76 to 9.40; P = 0.0003; I2 = 19%) and anterior (MD = 4.87%; 95% CI: 2.84 to 6.89; p<0.00001; I2= 0%) directions. Very low level of certainty of evidence was found for composite score (MD = 6.42%; 95% CI: 5.03 to 7.82 P < 0.00001; I2 = 1%). Conclusions: neuromotor exercises improve dynamic balance in basketball players. Although, the certainty of evidence is still very low. So, our data should be cautiously interpreted.
