Medidas de efeito das intervenções em vozes saudáveis: uma revisão de escopo

trata-se de uma revisão de escopo baseada na questão de pesquisa: “Quais as medidas de avaliação vocal utilizadas para verificar o efeito da intervenção em indivíduos vocalmente saudáveis?” A busca foi realizada de forma eletrônica nas bases de dados MEDLINE (PubMed), LILACS (BVS), Scopus (Elsevier), Web of Science (Clarivate), Embase e Cochrane.

Critérios de seleção

a seleção dos estudos foi baseada na leitura dos títulos, resumos, palavras-chave e textos completos, aplicando-se os critérios de elegibilidade. Foram extraídos os dados relacionados às informações bibliográficas da publicação, características da amostra e da intervenção, os efeitos da intervenção nas medidas de autoavaliação, perceptivo-auditivas, acústicas, aerodinâmicas, eletroglotográficas, resultado do exame laríngeo, entre outros. Os dados foram resumidos e apresentados de forma quantitativa e descritiva.

Resultados

foram selecionados 97 artigos, entre os 979 estudos mapeados nesta revisão. A análise acústica foi a medida mais utilizada (n=70, 72,3%) para verificar os efeitos do treinamento vocal nos estudos selecionados, seguida pela eletroglotografia (n= 55, 56,7%), autoavaliação (n= 38, 39,2%), aerodinâmica (n= 33, 34,0%), julgamento perceptivo-auditivo (n= 22, 22,7%) e exame laríngeo (n= 16, 16,5%).

Conclusão

a análise acústica é a medida utilizada na maioria dos estudos para verificar o efeito da intervenção em indivíduos vocalmente saudáveis.
