Efeitos da terapia miofuncional orofacial de lábios realizados isoladamente e associados à fotobiomodulação na pessoa com Trissomia do cromossomo 21

Abstract

Introduction: Trisomy 21 (T21) is a genetic alteration characterized by the presence of an extra chromosome. The field of Orofacial Myofunctional Therapy (OMT) offers interventions to support the development of orofacial functions in this population. One strategy is the use of technologies associated with therapy, one of which is photobiomodulation. The combination of laser therapy with myofunctional training has shown promising results, and understanding the effects of this resource and its dosimetric parameters is highly valuable. Objectives: To identify the effects of orofacial myofunctional therapy combined with photobiomodulation on the orbicularis oris muscle in individuals with T21. Methods: This is an interventional, quantitative, controlled, and triple-blind study. The research was conducted with two groups: active laser combined with OMT and placebo laser combined with OMT. The Pró-Fono Lip and Tongue Biofeedback (PLL) was applied before and after the intervention. The analysis was both descriptive and inferential, based on data distribution. Results: Positive results were found in the experimental group (EG) when associated with low-level laser therapy (LLLT) at 100 mW. In the control group (CG), values decreased post-intervention. Conclusion: It was observed that the immediate effects of lip exercises were enhanced by the use of low-level laser therapy.
