An evidence-based approach to understanding and improving exercise counselling for adults with spinal cord injury ------------------------------------------------------------------------ ---------- **Aims:** The overarching aims of this project are: 1. to use dynamic system methods to better understand how, when and why spinal cord injury (SCI) exercise counselling leads to positive change in theory-based psychosocial determinants (e.g. self-efficacy) of exercise and exercise behavior among clients with SCI and 2. to co-develop and co-evaluate evidence-based modules to train theory- and evidence-based best-practices for SCI-specific exercise counselling. **Methods:** This project includes three studies aligning with the two phases of the Knowledge-to-Action framework: knowledge creation and action cycle. In study 1, we will work together with a multidisciplinary expert panel, including researchers, counsellors, SCI peer mentors, and representatives of community organizations, to co-create theory- and evidence-based best practices for SCI exercise counselling. In study 2, we will co-develop training modules to teach counsellors these best-practices. Finally, study 3 will be a randomized controlled trial to test the feasibility and efficacy of the modules. **Relevance:** Guiding by the IKT Guiding Principles (www.iktprinciples.com), we will meaningfully engage SCI community members throughout our projects ensuring that our research is relevant, useful and useable. The co-development of user-friendly, high-quality, evidence-based training modules will help counsellors to provide the best behavioral support to people with SCI. **Funding:** Craig H.
