Interventions focused on singing may provide additional benefits to
established voice and respiratory therapies, due to their greater emphasis on the
respiratory muscle control system in those with Parkinson's disease (PD)
progresses. The purpose of this study was to examine if singing can improve
voice, respiratory pressure and quality of life (QOL) in persons with PD. Methods
This pilot study measured the effects of a singing intervention in 27
participants with PD. Participants were assigned to a high (met twice weekly) or
low (met once weekly) dosage group. Voice, respiratory and QOL measures were
recorded before and after an 8-week singing intervention. Sessions were led by
board-certified music therapists and included a series of vocal and articulation
exercises and group singing. Results Both groups demonstrated significant
improvements in maximum inspiratory and expiratory pressure, as well as phonation
time. While other voice measures improved, they did not reach statistical
significance. Voice QOL and whole health QOL also significantly improved.
Conclusion These results suggest singing may be a beneficial and engaging
treatment choice for improving and maintaining vocal function and respiratory
pressure in persons with PD. Implications for Rehabilitation In a small sample,
group singing proved beneficial for improving voice and respiratory impairment in
persons with Parkinson's disease. Completing group singing one time per week for
8 weeks was as effective as completing group singing two times per week for 8
weeks in persons with Parkinson's disease. Group singing is an effective means of
improving overall quality of life in persons with Parkinson's disease.
