Effect of Massage Therapy and Occlusal Splint Therapy on the Electromyographic Activity and Mandibular Range of Motion in Individuals With Temporomandibular Disorder

Not Applicable

Completed

• Conditions: Temporomandibular Disorder
• Interventions: Other: Massage; Other: Occlusal splint

• Registration Number: NCT01874041
• Lead Sponsor: University of Nove de Julho

Brief Summary

The objectives of this study were to investigate the effects of massage therapy and occlusal splint therapy in the electromyographic activity and mandibular range of motion (ROM) in individuals with temporomandibular disorder (TMD) and compare the results with those obtained in a group of individuals without this disorder. Twenty-eight volunteers with TMD were randomly distributed into two groups, massage therapy and occlusal splint. Both treatments lasted 4 weeks. Fourteen individuals without TMD were consecutively allocated to the control group. The Fonseca's anamnestic index was used to characterize TMD and allocate the volunteers to either the intervention groups or control group. The electromyographic activity and Mandibular ROM was evaluated before and after treatment using a digital caliper. Two-way analysis of variance with the Bonferroni test was used for inter and intragroup comparisons (level of significance was set to 5%). Cohen's d was used to calculate the effect size.

Arm && Interventions

Group	Intervention	Description
Massage group	Massage	The massage group was submitted to three weekly 30-minute sessions of massage of the muscles of mastication over four consecutive weeks.
The occlusal splint group	Occlusal splint	The occlusal splint group was submitted to treatment with an occlusal splint for four weeks.

Primary Outcome Measures

Name	Time	Method
Mandibular range of motion	1 year	Mandibular range of motion(maximum active mouth opening, and right and left lateral excursion) was evaluated by a blinded examiner on two occasions (before and after treatment) using a digital caliper.

Secondary Outcome Measures

Name	Time	Method
Electromyographic activity	1 year	Electromyographic activity in the masseter and anterior temporal muscles. The right and left masseter and anterior temporal muscles were analyzed with surface EMG.
