Mandibular kinematics and masticatory muscles EMG in patients with short lasting TMD of mild-moderate severity

Influence of craniomandibular and cervical pain on the activity of masticatory muscles in individuals with Temporomandibular Disorder

“…The results of this study showed that individuals with TMD showed greater asymmetry in the activation of the AT muscle during mastication's AP . Corroborating these findings, other studies (7,10) have observed greater asymmetry in the masticatory activity in patients with TMD. However, the study period was not the same.…”

“…However, the study period was not the same. The entire cycle of mastication was more asymmetric during activation of the AT (10) , MA (7,10) , and sternocleidomastoid muscles (7) . The asymmetry in the activation of masticatory muscles is interpreted as a compensatory strategy to find stability for the mandibular and cervical regions during mastication (7,23) .…”

“…Some studies (5,7,9,10) have shown that patients with TMD, compared to asymptomatic patients, showed alterations in the activity of the masticatory muscles during chewing. However, the cited studies are not conclusive.…”

Regulación voluntaria de la actividad contráctil del músculo masetero en individuos sanos y con trastornos temporomandibulares. Un potencial test diagnóstico

“…It assesses muscle function through the analysis of electric signals produced during the contraction of the muscle (3,4) . Because they are easily accessible to place the electrodes, superficial electromyography has been widely used to assess the electrical activity of the masseter and temporalis muscles, thus becoming a very useful tool in this field of study (4,5) .…”

Efeito de exercícios motores orofaciais e laserterapia nos sintomas de desordem temporomandibular e funções orofaciais

“…Quando existe um desequilíbrio neste sistema, surgem vários problemas clínicos, dentre os mais citados na literatura estão dor nos músculos mastigatórios, nas ATMs, limitação dos movimentos mandibulares, ruídos articulares (Dworkinet al, 1990;Greene et al, 2010;Murphy et al, 2013;Gomes et al, 2014), cefaléia, dor na região cervical (Armijo-Olivo e Magee, 2013;De Felício et al, 2013) e sintomas auditivos (Tuz et al, 2003;De Felício et al, 2008;Kitsoulis et al, 2011;Ferendiuk et al, 2014), bem como dificuldade e prejuízo na realização das funções orofaciais (Felício, 1999;Bianchini, 2000;Greene et al, 2010;Ferreira et al, 2014).…”
