Photobiomodulation in speech-language-hearing therapy: a profile of professional practice and the level of information of Brazilian speech-language-hearing therapists

ABSTRACT Purpose: to know the profile of Brazilian speech-language-hearing (SLH) therapists and their level of information on the use of low-level laser photobiomodulation. Methods: an observational, cross-sectional, quantitative study conducted with a self-administered online questionnaire related to the professional education, work, and knowledge of SLH therapists on low-level laser photobiomodulation. Two hundred sixty-one speech-language-hearing therapists of both sexes participated in the research. The data were analyzed with descriptive and inferential statistics. Results: the speech-language-hearing therapists had graduated predominantly 10 to 20 years before, their highest degree was mainly specialization, and most of them worked in the fields of oral-motor functions, dysphagia, voice, language, and audiology. Most of them knew photobiomodulation and its use in SLH therapists; also, they agreed on using a low-level laser as a therapeutic resource. Even so, most did not use it in clinical practice, although those who did, reported greater patient adherence. Statistical significance was verified for the association between laser use and access to resolution number 541 of the Federal Speech-Language-Hearing Council, time in the profession, main specialization, and required qualification. Conclusion: the participating speech-language-hearing therapists showed knowledge on low-level laser photobiomodulation and its applicability. However, most of these professionals did not use the resource yet.
