Dispositivos e incentivadores respiratórios utilizados na terapia vocal: revisão de literatura

Abstract

Purpose: To describe the main controlled devices used in voice therapy and their effects. Methods: A narrative review of the literature was carried out using the Scielo, PubMed, LILACS, and Medline databases. The search considered articles published between 2012 and 2022, in English or Portuguese, primary studies, and with available access. Results: For this study, 15 articles were selected in total, eight national and seven international publications. Six controlled devices and incentives were found, used as therapeutic resources associated with vocal speech therapy. Conclusion: The main devices used in voice therapy are: Shaker®, Threshold®, EMST150™, and POWERbreathe. The effects produced differed according to the type of device, target audience, and execution time of the intervention with the device. Among the main vocal effects is an increase in maximum phonatory time and modification of acoustic parameters.
