    ParkinSong: A Controlled Trial of Singing-Based Therapy for Parkinson's Disease
    Tamplin, J ; Morris, ME ; Marigliani, C ; Baker, FA ; Vogel, AP (SAGE PUBLICATIONS INC, 2019-06)
    Background. Communication impairment is one of the most common symptoms of Parkinson's disease (PD), significantly affecting quality of life. Singing shares many of the neural networks and structural mechanisms used during speech and, thus, has potential for therapeutic application to address speech disorders. Objective. To explore the effects of an interdisciplinary singing-based therapeutic intervention (ParkinSong) on voice and communication in people with PD. Methods. A controlled trial compared the effects of the ParkinSong intervention with an active control condition at 2 dosage levels (weekly vs monthly) over 3 months, on voice, speech, respiratory strength, and voice-related quality-of-life outcomes for 75 people living with PD. The interdisciplinary ParkinSong model comprised high-effort vocal and respiratory tasks, speech exercises, group singing, and social communication opportunities. Results. ParkinSong intervention participants demonstrated significant improvements in vocal intensity (P = .018), maximum expiratory pressure (P = .032), and voice-related quality of life (P = .043) in comparison to controls. Weekly ParkinSong participants increased vocal intensity more than monthly participants (P = .011). Vocal intensity declined in nontreatment control groups. No statistical differences between groups on maximum phonation length or maximum inspiratory pressure were observed at 3 months. Conclusions. ParkinSong is an engaging intervention with the potential to increase loudness and respiratory function in people with mild to moderately severe PD.

    Efficacy of Parkinsong Groups for improving Communication and Wellbeing in Parkinson's Disease
    Tamplin, J ; Vogel, A ; Marigliani, C ; Baker, FA ; Davidson, J ; Morris, ME ; Mercadal-Brotons, M ; Clements-Cortes, A (World Federation of Music Therapy, 2017)
    Communication impairment is one of the most common symptoms of Parkinson’s disease, significantly impacting quality of life (Miller, 2012). Speech characteristics may include a soft, monotone, breathy or hoarse voice quality, imprecise articulation, dysprosody and dysfluency (Skodda et al., 2013). These characteristics, combined with reduced nonverbal communication, cognitive-linguistic impairment and poor self-perception of speech, make communication difficult and lead to self-consciousness, reduced likelihood to participate in conversation, and the avoidance of social interaction that requires speaking. Communication difficulties can compound issues of depression and related social isolation (Miller et al., 2006).
