About

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.

Full 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%.

33 participants in 3 patient groups

Hyperbolid combined with tongue exercises on the palate

Experimental group

Description:

The proprioceptive treatment protocol if run in the use of exercises with hyperboloid based on studies of Biasotto-Gonzalez (2005), for each exercise will be held 6 sets of 6 reps. Between exercises, 1 minute will be established for rest of the volunteer, in order to avoid muscle fatigue and possible exacerbation of pain, and after that period you will be asked to volunteer the proprioceptive exercise of ´ ´ tongue on the hard palate ´ ´ Biasotto-Gonzalez-based (2005), which consists of the language supported in the hard palate, you must open and close the mouth, having as the principle language as a physical reference.

Treatment:

Behavioral: hyperbolid combined with tongue exercises on the palate

Hyperbolid

Active Comparator group

Description:

The proprioceptive treatment protocol if run in the use of the hyperboloid, based on studies of Biasotto-Gonzalez (2005), but without the proprioceptive exercise of language in ´ ´ hard palate ´ ´. For each exercise will be held 6 series of 6 repetitions, and between exercises, 1 minute will be established for rest of the volunteer, in order to avoid muscle fatigue and possible exacerbation of pain.

Treatment:

Other: hyperbolid

Control

No Intervention group

Description:

The individuals in control group did not receive any type of intervention, being offered proprioceptive treatment after the study period.
