In 30 seconds
The Sparky Samba trial is a multi-centre, non-blinded, randomised controlled feasibility trial assessing a samba percussion intervention for individuals with Parkinson's disease. Sixty participants will be randomized to either the Sparky Samba group or continue their usual activities for 12 weeks. The primary outcome is feasibility, focusing on recruitment and retention rates.
Key findings
- The trial will assess feasibility through recruitment, retention, data completeness, and intervention adherence.
- Secondary outcomes will evaluate motor function, cognition, well-being, and self-efficacy at baseline and 12 weeks.
- Qualitative interviews will explore contextual mechanisms surrounding the Sparky Samba intervention.
Why it matters
Understanding the feasibility of community-based interventions like Sparky Samba could inform future studies and enhance physical activity options for individuals with Parkinson's disease, potentially improving their quality of life.
