Background: Physical inactivity is both the second-highest population attributable risk factor for and a common consequence of stroke. Despite well-documented health benefits associated with physical activity, its levels typically remain below recommended guidelines in stroke survivors. Consequently, calls have been made for novel interventions targeting the promotion of physical activity in stroke survivors. Mobile health is an emerging field which can offer personalised health interventions through mobile and wireless technology. However, a paucity of research has focused on mobile health to promote physical activity in stroke survivors and, more broadly, this field has been criticised for not incorporating the views of stakeholders. This study aims to explore the perspectives of stroke survivors and healthcare professionals on the development of a mobile health intervention for the promotion of physical activity. Methods: The current study will employ a qualitative descriptive approach using separate, semi-structured focus groups for two key stakeholder groups. Community-dwelling stroke survivors will be recruited through an early supported discharge service for acute stroke and stroke support groups. Healthcare professionals will be recruited through the same early supported discharge service, relevant professional bodies and Twitter. The final number of focus groups will depend on data saturation. Thematic analysis will be conducted using NVivo 12 and findings will be reported in accordance with the Consolidated Criteria for Reporting Qualitative Studies. Conclusion: This study was granted ethical approval from the HSE Mid-Western Regional Hospital Research Ethics Committee and the Faculty of Education and Health Sciences Research Ethics Committee at the University of Limerick. Output will consist of recommendations for the development of a mobile health intervention aimed at the promotion of physical activity in stroke survivors. Findings will be disseminated locally through presentations at stroke support groups, as well as internationally through academic conferences and peer-reviewed journals.
