Co-Design of a Physical Activity Maintenance Intervention for People With Stroke: Protocol for a Mixed Methods Study

Background: Stroke is a global health problem that often causes physical disability and mental health issues for the survivor. While physical activity (PA) improves outcomes post stroke, it can be challenging to maintain. Barriers to maintaining PA post stroke include the setting of PA, motivation, and impairments from the stroke. There is often a desire to maintain PA after stroke, but effective interventions are currently limited. Objective: This study aims to coproduce an intervention to support long-term PA maintenance for adults living with the effects of stroke in Northern Ireland. The objectives of this study are to understand the perspectives of key stakeholders on the components, structure, and content of an intervention to support PA maintenance and to coproduce and refine a prototype intervention to meet their specific needs and preferences. Methods: A mixed methods study will be conducted, consisting of three stages informed by the Centre for Development, Evaluation, Complexity and Implementation in Public Health Improvement (DECIPHer) co-production framework. Stage 1 will include a scoping review on PA maintenance in survivors of stroke and stakeholder consultation via focus groups to gain understanding from their perspective of PA. Survivors of stroke and their carers, physiotherapists, and care coordinators from community and voluntary organizations will be recruited from ongoing Post Rehabilitation Exercise Program (PREP) classes. Additional health care professionals with experience in PA and stroke will also be recruited via relevant organizations. Individuals who complete stage 1 focus groups will be invited to take part in stage 2 co-design workshops to develop a PA maintenance program for participants post PREP. Stage 3 will involve expert review of the co-production program by members of the project advisory board via a questionnaire survey. Qualitative data will be analyzed using reflexive thematic analysis from data collected in stages 1 and 2. Data from the scoping review will help shape the questions for the focus groups, and data from the focus groups will help inform questions for the three workshops. All stages will involve the stakeholders to gain feedback and suggestions for the next wave. Results: Five focus groups were conducted with 38 participants: three in-person (stroke survivors and their caregivers) and two online (one for PREP staff and one for other health and exercise professionals) between September and November 2025. Results from the focus groups identified two themes: shifting realities of physical activity post stroke and motivation through community. Eighteen participants subsequently consented to participate in three co-design workshops, which resulted in an intervention prototype being developed. Conclusions: This study aims to co-develop an intervention to support PA maintenance in adults living with stroke after completion of community rehabilitation. To our knowledge, there is no further support for the survivors to help maintain their PA levels once they finish the 6- to 12-week community program. Engaging with survivors of stroke and their carers, PREP staff, and other exercise professionals will help shape the beginning stages of this study. Upcoming results from the pilot study will provide vital information on how to support PA maintenance in this population.
