Efeito de exercícios mioterápicos de bochechas

Abstract

Introduction: Through myotherapy isotonic and / or isometric exercises are used in clinical practice to promote new muscle patterns that may influence the outcome of speech therapy. Objective: To analyze the effectiveness of cheek exercises by investigating data provided by surface electromyography (EMG). Material and methods: A quantitative longitudinal interventional study conducted in a speech language clinic with 22 young women. Data were collected by measuring the electrical activity during bilateral task of the buccinator muscle by the MIOTEC two-channel electromyographic, pre and post isometric or isotonic exercise training indicated by the Orofacial Motricity professionals as the most used in clinical practice. The nonparametric statistical tests used were Mann Whitney Intergroups and Wilcoxon Signal Intragroup with 5% significance. Results: The most indicated exercises were (A) Alternate Air, (B) Alternate Water, (C) Cheek Suction and (D) Inflate Cheeks. There were no significant results in the intergroup comparison between exercises A and B, and C and D. In the intragroup analysis there were statistically significant changes in the recruitment of motor units in several tests of the group that performed isotonic exercise A, and in the maximum test. sustained voluntary activity on the right side in isometric exercises C and D. Conclusion: Exercises A, C and D promoted higher level of electrical activity of the buccinator muscle in women without oromiofunctional alterations.
