Intervenções vocais diretas e indiretas em professores: revisão sistemática da literatura

Direct and indirect vocal interventions on teachers: systematic review of the literature

Resumos

OBJETIVO: Verificar a eficácia das intervenções vocais diretas e indiretas, de forma isolada e combinada, na prevenção de distúrbios vocais em professores, por meio de revisão sistemática da literatura. ESTRATÉGIAS DE PESQUISA: Foram pesquisados artigos de janeiro de 1980 a abril de 2013, nas bases de dados eletrônicas MEDLINE (acessado pelo PubMed), PubMed, LILACS, SciELO, Scopus e Web of Science. CRITÉRIOS DE SELEÇÃO: Foram incluídos todos os artigos que tinham como objetivo principal algum tipo de intervenção com professores e que fossem ensaios controlados randomizados. Excluíram-se artigos que apresentavam indivíduos com alterações de laringe e voz e que estivessem afastados de sua profissão. RESULTADOS: Como resultado da busca inicial, foram identificados 677 estudos, dentre os quais, cinco atendiam aos critérios de inclusão. Somou-se a esses mais quatro artigos, encontrados nas referências bibliográficas dos estudos selecionados para a fase de leitura do texto completo. CONCLUSÃO: A intervenção combinada (direta e indireta) apresentou melhora significativa em parâmetros da qualidade vocal e na autoavaliação da voz, mesmo em curto período de tempo. Em outros estudos, cujo foco era a comparação entre a intervenção combinada e intervenções isoladas (direta ou indireta), não foram observadas diferenças significativas, apesar de serem descritas melhoras em alguns dos parâmetros vocais avaliados. Como limitação desta revisão, pode-se incluir a restrição quanto ao desenho metodológico dos estudos, incluindo apenas ensaios clínicos randomizados. A intervenção vocal combinada apresenta resultados mais expressivos do que a intervenção isolada.

PURPOSE: The aim of this work is to verify the efficacy of direct and indirect vocal interventions in preventing voice disorders, with specific and combined strategies, by a systematic review of the literature. RESEARCH STRATEGIES: Articles published from January, 1980 to April, 2013 were searched in the electronic databases MEDLINE (accessed through PubMed), PubMed, LILACS, SciELO, Scopus and Web of Science. SELECTION CRITERIA: All the articles that presented randomized controlled studies with some type of vocal intervention with teachers as their primary aim were included. Articles that presented subjects with larynx and voice alterations were excluded. RESULTS: As a result of the initial search, 677 studies were identified, five of which followed the inclusion criteria. Four more articles, found in the references of the studies selected for reading of the full text, were included. CONCLUSION: The combined intervention (direct and indirect) presented a significant improvement in vocal quality parameters and self-assessment, even in a short period of time. In other studies, which focused on the comparison between combined and specific interventions (direct or indirect), no differences were observed, although improvements in some of the assessed vocal parameters were described. A limitation of this review is the restriction of the methodological design of the studies, including only randomized clinical trials. The combined vocal intervention presented more significant results than the specific intervention.
