| Popis: | Summary The present study aimed to perform a systematic literature review to assess the effects of phonation therapy on voice quality and function in singers. The systematic search was performed in February and updated in October 2017. No restriction of year, language, or publication status was applied. The primary electronic databases searched were LILACS, SciELO, PubMed, and Cochrane. Kappa coefficient was used to assess the agreement between examiners in judging article eligibility. The eligible articles were analyzed based on their risk of bias using the tools proposed by the Joanna Briggs Institute. Mendeley Desktop 1.13.3 software package (Mendeley Ltd, London, UK) was used to standardize the references of identified articles. The general sample consisted of 1965 articles screened out of the electronic databases. Two examiners analyzed the sample in the search for eligible articles. The agreement between examiners reached excellent outcomes (kappa coefficient = 0.88). After the selection, phase 6 articles remained eligible. Together, the eligible studies accounted 141 subjects (65 men and 76 women) aged between 18 and 72 years old. Electroglottography was considered as the most common method (83.33%) of assessment of the effects of phonation therapy in singers. The most prevalent exercises within the therapies were phonation into straws and phonation into glass tubes. The phonation into glass tubes immersed in water, straws, and LaxVox tubes promoted positive effects on the voice quality in singers, such as more comfortable phonation, better voice projection, and economy in voice emission. |
