After a stroke, many people discover something frustrating and isolating; the brain can know what it wants to say, but the words will not cooperate. That is aphasia, a communication disorder that can affect speaking, understanding, reading, and writing. Some readers may recall that aphasia, caused by a neurological disorder, is what caused the retirement of actor Bruce Willis. For many stroke survivors, these challenges linger well beyond the short window when rehab is typically most intensive, with real impacts on confidence, relationships, and quality of life.
So here’s the big, hopeful question researchers are testing right now: if speech is hard, could singing help open a different door?
What the study is actually doing (and why it matters)
A new multicentre randomised controlled trial is putting community choir singing to the test for people living with chronic post stroke aphasia. Professor Anna Zumbansen is leading the study from the University of Ottawa’s School of Rehabilitation Sciences. The “community” part is key. This is not a lab-only experiment, it is designed to reflect real life, with sessions happening at multiple sites (including Montreal, Ottawa, Toronto, and Tampa Bay) so the results are more likely to translate into everyday care.
Here’s the core process:
- 12 weekly, in person choir sessions, about 1.5 hours each, led by a choir leader.
- Home singing practice, three 30 minute sessions per week, so participants are not only “doing choir”, they are also building consistency between sessions.
- A randomised AB/BA design with a crossover, meaning everyone gets a chance to receive the choir program, just in a different order compared to usual care.
- Researchers also track what “usual care” looks like in the real world, with short weekly check-ins about social activities, rehab services, and any adverse events.
They are measuring outcomes at “macro” time points (baseline, program completion, and a two-month follow-up), plus “micro” snapshots at selected choir sessions to see what changes might show up during and around the singing itself.
What outcomes are they hoping to see?
The primary focus is whether being assigned to choir singing can improve functional communication and language recovery, along with psychosocial outcomes like social connection and participation. That matters because aphasia is not only about vocabulary or sentence structure. It is also about being able to order a coffee, tell a story, participate in family life and feel like yourself again.
Why singing might help, even when speech is stuck
Singing is often relatively preserved in aphasia, and music based approaches have long suggested that rhythm and pitch can support communication in different ways than speech drills alone. The exciting part here is that a choir adds something extra: repetition, structure, breath control, shared timing and a built-in social circle.
We are not starting from zero. Prior research has found that group-based singing interventions can improve everyday communication and social participation for people with chronic aphasia, with benefits that can last months after the program ends.
The takeaway (for families, clinicians, and communities)
This study is still in progress, so there are no final results yet. But the approach is promising because it is practical, scalable and deeply human. If the outcomes show meaningful gains, community choirs could become a powerful, low barrier add on to traditional speech language therapy, especially for people who feel they have “aged out” of rehab.
