Abstract

BackgroundThe 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-DesignA 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.

DiscussionA 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.
