Cervical and scapular instability in subjects with temporomandibular disorder

Abstract

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.

Ausência Bilateral Do Músculo Quadrado Femoral – Relato De Caso

“…Sabe-se que a proximidade anatômica, as interconexões neuronais e as entradas de convergência trigeminal nas áreas cervicais sugerem associação entre DTM e transtornos cervicais. Além disso, tem sido relatado que assim como a coluna cervical, a cintura escapular pode ser afetada por instabilidades durante os movimentos torácicos e dos ombros de uma forma mais frequente em indivíduos com DTM do que naqueles sem essa doença (VIEIRA et al, 2018).…”

Effect of Short-Term Forward Head Posture Correction for Masseter Muscle Activity and Temporomandibular Joint Function for People with Upper Cross Syndrome

“…Kai mentė vienoje kūno pusėje yra nutolusi nuo stuburo labiau, toje pačioje pusėje matomas krūtinės raumenų sutrumpėjimas, o į priešingą pusę -mažesnė AŽ nuokrypio į šoną amplitudė. Tyrėjai pateikė išvadą, kad koreliuoja kaklinės stuburo dalies ir menčių biomechaniniai sutrikimai, todėl fizinis ištyrimas ir taikoma kineziterapija turi būti sutelkta į abu šiuos regionus (Vieira et al, 2018).…”
