From Soundwaves to BrainWaves: The effects of choral singing on recovery from stroke and aphasia

Background Stroke is a leading cause of death and disability. Recovery is frequently compromised by reduced well-being, mood, socialisation and quality of life. Music and singing are recognised as enhancing well-being and benefit people with chronic illness. Evidence suggested that choir singing may improve the fluency of people with aphasia. Choirs existed for people with brain impairment; no studies had robust design and outcome measurement. Aim To conduct a pilot study in Newcastle, Australia in a collaboration between Hunter New England Health and the University of Newcastle. To explore the effects of choral singing on quality of life, well-being, mood, social participation and communication skills of community-dwelling stroke survivors including people with aphasia. Method A mixed methods waitlist control design was used. 39 people at least 6 months post-stroke were assessed before and after a 12-week choir rehearsal period. Carers were invited to participate. Subjects were interviewed at the end of the period. Results Measures of communication improved significantly and a trend to improvement in overall quality of life was seen. Depression and disability were significant in their impact on overall quality of life scores. Qualitative work reported increased quality of life, confidence, independence, mood and socialization and improvements in speech and communication were also reported. Conclusion Our pilot showed that a 12-week choir program for stroke survivors and carers is feasible and benefits quality of life, well-being, mood, community participation and communication in people with aphasia.
