The stomatognathic system and dysfunction in this system may be related to postural control. The proposal of the present study is to assess the effect of mandibular mobilization in individuals with temporomandibular disorder using surface electromyography of the muscles of mastication and stabilometric variables.
METHODS/DESIGN: A randomized, controlled, blind, clinical trial will be carried out, with the participants divided into three groups: 1) facial massage therapy (control group), 2) nonspecific mandibular mobilization and 3) specific mandibular mobilization. All groups will be assessed before and after treatment using the Research Diagnostic Criteria for Temporomandibular Disorders, surface electromyography of the masseter and temporal muscles and stabilometry. This study is registered with the Brazilian Registry of Clinical Trials (RBR9x8ssz).
A large number of studies have employed surface electromyography to investigate the function/dysfunction of the muscles of mastication and associations with signs and symptoms of temporomandibular disorders. However, it has not yet been determined whether stabilometric variables offer adequate reliability in patients with this disorder. The results of the proposed study will help determine whether specific and/or nonspecific mandibular mobilization exerts an effect on the muscles of mastication and postural control. Moreover, if an effect is detected, the methodology defined in the proposed study will allow identifying whether the effect is local (found only in the muscles of mastication), global (found only in postural control) or generalized.
口颌系统及其功能障碍可能与姿势控制有关。本研究的目的是通过咀嚼肌表面肌电图和稳定测量变量，评估下颌松动术对颞下颌关节紊乱患者的影响。
方法/设计：将进行一项随机、对照、盲法临床试验，参与者分为三组：1）面部按摩疗法（对照组），2）非特异性下颌松动术，3）特异性下颌松动术。所有组在治疗前后均使用颞下颌关节紊乱研究诊断标准、咬肌和颞肌表面肌电图以及稳定测量法进行评估。本研究已在巴西临床试验注册中心注册（注册号：RBR9x8ssz）。
大量研究采用表面肌电图来研究咀嚼肌的功能/功能障碍以及与颞下颌关节紊乱体征和症状的关联。然而，尚未确定稳定测量变量在该疾病患者中是否具有足够的可靠性。本研究的结果将有助于确定特异性和/或非特异性下颌松动术是否对咀嚼肌和姿势控制产生影响。此外，如果检测到有影响，本研究中定义的方法将有助于确定这种影响是局部的（仅在咀嚼肌中发现）、全身性的（仅在姿势控制中发现）还是全身性的。
