Abstract

Purpose: to identify the usage profile of mirrors and electromyographic biofeedback to support myofunctional therapy by speech-language-hearing therapists who work with oral-motor function in Brazil.

Methods: a quantitative cross-sectional study with an online (SurveyMonkey) questionnaire, which was structured with questions on the use of mirrors and/or electromyographic biofeedback. A descriptive analysis was made, and the Mann-Whitney U test and the chi-square test were applied (p < 0.05).

Results: most professionals (23 [82.14%]) used mirrors, whereas only five (17.85%) used electromyographic biofeedback. The electromyographic biofeedback was used at some point with all age groups, to treat mastication and swallowing functions and facial mimics. Dysphagia and facial palsy were regularly or occasionally treated with it. The patients’ perception was significantly associated with the use of either instrument. The electromyographic biofeedback group showed a consensus among patients, while approximately half of the mirror group (12 [52.17%]) were indifferent to its use.

Conclusion: the profile showed young adult professionals, who used national equipment. The findings reinforce the need for research on complementary therapeutic procedures in the field of oral-motor functions, particularly, electromyographic biofeedback.

Resumo

Objetivo: identificar o perfil de uso do espelho e do Biofeedback Eletromiográfico como suporte à terapia miofuncional por Fonoaudiólogos atuantes na área de Motricidade Orofacial no Brasil.

Métodos: estudo quantitativo e transversal, por meio da aplicação de questionário online (plataforma SurveyMonkey). O questionário foi estruturado com perguntas sobre o uso do espelho e/ou do Biofeedback Eletromiográfico. Foi realizada análise descritiva e aplicação dos Testes U de Mann-Whitney e Qui-quadrado (p<0,05).

Resultados: a maioria dos profissionais, 23 (82,14%), utiliza o espelho, enquanto apenas cinco (17,85%) utilizam o biofeedback eletromiográfico. O Biofeedback Eletromiográfico é eventualmente utilizado em todas as faixas etárias, assim como para as funções de mastigação, deglutição e mímica facial. As patologias referidas com uso regular e eventual foram a disfagia e a paralisia facial. Houve associação significante na percepção dos pacientes em relação ao uso de algum dos instrumentos, porém no grupo do Biofeedback Eletromiográfico houve consenso entre os pacientes e, no grupo espelho, aproximadamente metade 12 (52,17%) achou indiferente.

Conclusão: o perfil encontrado foi de profissionais adultos jovens, com uso de instrumentação nacional. Os achados reforçam a necessidade de pesquisas voltadas aos procedimentos terapêuticos complementares na área de Motricidade Orofacial, sobretudo Biofeedback Eletromiográfico.
