Proprioceptive Treatment for Temporomandibular Dysfunction
Condition: Facial Pain
MeSH terms: Temporomandibular Joint Disorders; Temporomandibular Joint Dysfunction Syndrome; Facial Pain
Study type: Interventional

Summary: 
      The project aims to assess the effects of proprioceptive treatment through the use of
      hyperbolid mastication apparatus on pain intensity, muscle activity and joint mobility in
      subjects with TMD. A randomized, blind, clinical trial will be conducted. Volunteers aged
      between 18 and 40 years will be recruited, with a diagnosis of muscle- and joint-related TMD
      according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC / TMD),
      being randomly divided in three different groups: Group 1 (G1) - treated with HB device
      combined with tongue exercises on the palate; Group 2 (G2) - treated HB alone and Group 3
      (G3) - control. Treatment protocols will be applied for 12 sessions, the volunteers will be
      evaluated in two stages: before applying the treatment and after the last session.
    

Detailed description: 
      The temporomandibular disorder (TMD) are characterized by a set of clinical abnormalities
      involving the masticatory muscles, the temporomandibular joint (TMJ) and other associated
      structures. Several studies have supported the use of physical therapy in the treatment of
      this condition, especially electrotherapy, laser therapy and manual resources. However,
      despite advances in the search for scientific evidence, it is necessary to prove to other
      commonly used clinical measures in subjects with TMD, such as the use of hyperbolid, which is
      a feature that stimulates the proprioceptive function. Thus, this project aims to assess the
      effects of proprioceptive treatment through the use of hyperbolid on pain intensity, muscle
      activity and joint mobility in subjects with TMD. A randomized, blind, clinical trial will be
      conducted. Volunteers aged between 18 and 40 years will be recruited, with a diagnosis of
      muscle- and joint-related TMD according to the Research Diagnostic Criteria for
      Temporomandibular Disorders (RDC / TMD), being randomly divided in three different groups,
      the first group constituted by treatment with hyperbolid associated with tongue exercises on
      the palate, the second group consists of treatment with hyperbolid alone and the third group
      will not receive any type of intervention (proprioceptive treatment will be offered after the
      study period). Treatment protocols will be applied for 12 sessions, the volunteers will be
      evaluated in two stages: before applying the treatment and after the last session. The
      variables that will be investigated are: pain assessed using visual analog scale and
      algometry; muscle activity, investigated by electromyography of masticatory muscles; and
      joint mobility, measured by the use of a caliper. Regarding the analysis of the data will be
      held intragroup comparisons, considering the pre-treatment and after twelve sessions, and
      comparisons between groups. To this end it will be applied the Shapiro-Wilk test for checking
      the normality of data, and the statistical test applied consistent, then parametric or
      nonparametric. Is assumed a significance level of 5%.
