A controlled trial of ParkinSong singing groups to improve communication and wellbeing in Parkinson’s disease

Objective: To explore the effects of a therapeutic group singing intervention (ParkinSong) on communication and wellbeing outcomes for people living with Parkinson’s disease. Background: Communication impairment is one of the most common symptoms of Parkinson’s disease, significantly impacting quality of life, yet few seek help for this. [1] Singing shares many of the neural networks and structural mechanisms used during speech. [2] Therapeutic group singing sessions can be designed specifically to target the functional communication issues resulting from Parkinson’s disease and to provide rhythmic cues to stimulate and organise motor speech output. [3] Methods: A controlled clinical trial measured the effects of a ParkinSong group singing intervention, at 2 dosage levels (weekly versus monthly) over 3 months, on voice, speech, respiratory, and wellbeing outcomes for 77 people living with Parkinson’s disease. The ParkinSong model comprises high effort vocal and respiratory tasks, speech exercises, group singing, and social communication opportunities. Control participants took part in regular peer support and/or creative activity groups that did not involve singing. Results: ParkinSong intervention participants demonstrated significant improvements in vocal intensity (p=0.001), maximum expiratory pressure (p=0.006), and voice-related quality of life (p=0.020) in comparison to controls. Weekly ParkinSong participants increased vocal intensity more than monthly participants (p = 0.011). Vocal intensity declined in non-treatment control groups. No changes in speech intelligibility, maximum phonation length, or health-related quality of life were observed. Conclusions: Group singing is an effective and engaging therapy to increase loudness and increase respiratory function in people with mild to moderately severe Parkinson’s disease References: 1.
