Voice therapy with a respiratory approach in older people: an integrative literature review

Abstract

ABSTRACT Purpose: to characterize voice therapy with a respiratory approach in dysphonic older people. Methods: a search made in PubMed, VHL, Scopus, Web of Science, and EMBASE. Original studies in English, Spanish, and Portuguese, addressing voice therapy in combination with a respiratory approach in the older population, were included. The analysis encompassed sex, age, associated etiology, session frequency and duration, exercise dosage, intervention, and benefits. Results: altogether, 1,425 articles were found, of which only nine were included in the review. In voice therapy for older people, the following strategies stood out: Vocal Function Exercises, Lee Silverman Voice Treatment®, ParkinSong, and tubes immersed in water. These approaches change the laryngeal muscle function and respiratory impulse and support and increase vocal intensity. The main therapeutic findings included improved auditory-perceptual, acoustic, and aerodynamic parameters, maximum phonation time, phonatory effort level, and voice quality. Conclusion: voice therapy with a respiratory approach characteristically used strategies aimed at both the general older population and those with neurological dysphonia. Their results showed improvement in frequency, resonance, intensity control, and breathing/phonation coordination.
