Influência do tratamento proprioceptivo sobre a intensidade de dor, atividade muscular e mobilidade articular em indivíduos com disfunção temporomandibular: ensaio clínico, aleatorizado, controlado e cego

Abstract

Temporomandibular disorder (TMD) is characterized by a set of clinical abnormalities involving the masticatory muscles, the temporomandibular joint (TMJ) and other associated structures. However, evidence of other clinical measures commonly used in subjects with DTM, such as the use of the hyperboloid, which stimulates the proprioceptive function is required. Thus, this project aims to evaluate and compare the effects of treatment with proprioceptive versus treatment hyperboloid associated with the exercise of the tongue on the palate on the intensity of pain, muscle activity and joint mobility in patients with TMD. Treat yourself to a randomized, controlled and double blind. Study participants were 22 individuals diagnosed with TMD according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC / TMD), and randomly distributed in two groups: group 1 (hyperboloid associated with the exercise of the tongue on the palate) and group 2 (hyperboloid). Treatment protocols were applied for 12 sessions and subjects evaluated in two stages: before the first treatment session and after the last session. The variables investigated: The pain, assessed by visual analogue scale and algometry; the muscle activity, investigated by electromyography of masticatory muscles; and joint mobility, measured using a calipers. The results showed no statistically significant difference in electromyography activity of the temporal and masseter muscles compared pre and post treatments as well as between groups. With respect to pain and range of motion was no statistically significant difference (P <0.05) when compared before and after treatment, but no difference between groups. We can conclude by the end of this study that the proprioceptive treatment with hyperboloid and the proprioceptive treatment with hyperboloid associated with the exercise of the tongue on the palate decrease pain and increase range of mandibular motion, but did not differ, and both treatments did not influence the electromyography signal the temporal muscles and masseter TMD patients.
