Aim: To investigate the electromyographic activity of masticatory muscles in women with myogenic or mixed TMD treated with ultrasound and ultrasound associated with stretching. Methods: Sixteen women with myogenic or mixed TMD, according to the Research Diagnostic Criteria for Temporomandibular Disorder (RDC/TMD), participated in the study. The patients were evaluated using surface electromyography (sEMG) of the masseter and anterior temporalis muscles, during maximum intercuspation, before and immediately after application of therapeutic resources. All patients were treated by ultrasound (US), ultrasound associated with stretching and placebo ultrasound, by turns, once a week with a one-week minimum interval between them. Results: There was greater symmetry of the masseter muscle electrical activity after ultrasound associated with stretching (p=0.03). The electromyographic values for the maximum intercuspation as well as the symmetry of anterior temporal muscle (p=0.47, p=0.84, p=0.84) and anteroposterior coefficient (p=0.07, p=0.84, p=0.57) showed no statistically significant difference after the intervention, placebo, ultrasound and ultrasound with stretching. Conclusions: These results indicate that a single application of ultrasound and ultrasound associated with stretching were not able to modify the activity pattern of the masticatory muscles during maximum intercuspation, except the symmetry of the masseter muscle that increased with the last, in women with myogenic or mixed temporomandibular disorder.

Multimodal physiotherapeutic approach: effects on the temporomandibular disorder diagnosis and severity [I] Abordagem fi sioterapêutica multimodal: efeitos sobre o diagnóstico e a gravidade da disfunção temporomandibular [A] Ariane Bôlla Freire [a] , Angélica Trevisan De Nardi [b] , Jalusa Boufleur [c] , Laís Chiodelli [d] , Fernanda Pasinato [e] , Eliane Castilhos Rodrigues Corrêa [f] [a] Undergraduate Student, Universidade Federal de Santa Maria (UFSM), Santa Maria, RS -Brazil, e-mail:aribfreire@hotmail.com [b] Undergraduate Student, Universidade Federal de Santa Maria (UFSM), Santa Maria, RS -Brazil, e-mail:angelica_denardi@hotmail.com [c] Abstract Introduction: The temporomandibular disorder (TMD) consists of a set of signs and symptoms that affect the masticatory structures, which may cause joint and/or muscular pain. The physiotherapy approach aims at the pain relief and the functional recovery by means of several modalities. Objective: To investigate the effects, short and medium-term, of a multimodal physiotherapeutic approach on TMD diagnosis and severity. Methodology: Individuals with diagnosis of TMD, confirmed by the Axis I of the RDC/TMD, took part in the study. From this evaluation, the Temporomandibular Index (TMI) and its sub-indices were calculated. The participants were treated during ten sessions of physiotherapy, which included therapeutic ultrasound, thermotherapy, manual therapy, stretching and neuromuscular exercises, as well as self-care and home exercises instructions. Assessments were carried out before treatment (AV1), immediately after treatmentFisioter Mov. 2014 abr/jun;27(2):219-27Freire AB, De Nardi AT, Boufleur J, Chiodelli L, Pasinato F, Corrêa ECR. 220 (AV2) and two months after the end of the treatment (AV3). The values of indices and the diagnosis prevalence were compared between the different periods by the t paired test (p < 0.05). Results: The number of diagnoses reduced in all the subgroups and 41.7% of the 24 participants presented no diagnosis after the treatment. A significant decrease in the TMI was observed between AV1 and AV2 (p = 0.000). There was no difference between AV2 and AV3 (p = 0.204) in 13 participants assessed two months after the end of the treatment. Conclusion: The multimodal physiotherapeutic approach resulted in positive effects, short and medium-term, on the symptoms and clinical signs, with deletion of the dysfunction or reduction of its severity in treated patients.[

Objetivo: Avaliar a função ventilatória, o pico de fluxo inspiratório nasal, as pressões respiratórias máximas, a atividade elétrica dos músculos inspiratórios acessórios e a relação entre as variáveis, em adultos com respiração oral (RO), comparando-os com adultos com respiração nasal (RN). Métodos: Estudo transversal, controlado com 77 participantes, entre 18 e 30 anos, ambos os sexos, distribuídos em Grupo RO (n = 38) e RN (n = 39). Foram avaliados por espirometria, manovacuometria, para obtenção da Pressão Inspiratória Máxima (PImáx) e Pressão Expiratória Máxima (PEmáx); medida do pico de fluxo inspiratório nasal (PFIN) e eletromiografia de superfície (EMG) dos músculos esternocleidomastoideo (ECM) e trapézio superior durante testes de PImáx e PFIN. Resultados: O grupo RO apresentou valores significativamente menores de PImáx (91 versus 100%), PEmáx (91,6 versus 102,6%) e PFIN (121,4 versus 147,7 l/min). Houve diferença (p < 0,01) na atividade EMG do ECM, com valores menores no grupo RO. A PImáx se correlacionou com o PFIN (r = 0,48, p < 0,01). Conclusão: Os RO apresentaram menores valores de PFIN, PImáx, PEmáx e de amplitude da atividade EMG dos músculos inspiratórios acessórios durante inspirações rápidas, quando comparados aos RN. Traz como contribuição para a prática clínica, a importância de uma investigação global do modo respiratório, não envolvendo apenas intervenções médicas, ortodônticas e miofuncionais, mas também os aspectos ventilatórios e musculares, sobre os quais se identificou a influência da RO.Palavras-chave: músculos respiratórios, espirometria, eletromiografia, obstrução nasal, respiração bucal.
