An Exercise and Lifestyle Programme for Adults With Vascular Ehlers-Danlos Syndrome: A Feasibility Study

2026년 7월 9일 업데이트: Markos Klonizakis, Sheffield Hallam University

Co-Producing and Piloting an Exercise-Based Lifestyle Intervention for Individuals With Vascular Ehlers-Danlos Syndrome (vEDS): A Mixed-Methods Feasibility Study

Vascular Ehlers-Danlos syndrome (vEDS) is a rare, life-threatening connective tissue disorder. People with vEDS have often been advised to limit physical activity, yet the safety and feasibility of structured exercise in this group is poorly understood. This study works with people with vEDS, their families and clinicians to co-design a safe, tailored physical activity programme, then tests it in a 12-week randomised feasibility study comparing the programme with usual care. The aim is to find out whether the intervention and the trial procedures are safe, acceptable and practical, in order to inform a future full-scale trial. Outcomes focus on recruitment, retention, adherence, acceptability and safety, alongside exploratory measures of physical function, quality of life and microvascular health.

연구 개요

상세 설명

This is a mixed-methods feasibility study delivered across four phases. Phase 1 uses qualitative interviews with people with vEDS, family members and clinicians to understand experiences of physical activity and decision-making under uncertain clinical guidance. Phase 2 uses co-production focus groups to design the exercise-based lifestyle intervention. Phase 3 is a 12-week randomised feasibility trial in which adults with vEDS are randomised to the co-produced intervention or to usual care, assessing feasibility outcomes (recruitment, retention, adherence, data completeness, acceptability and safety) and exploratory clinical measures. Phase 4 uses post-intervention interviews to explore participant experiences and refine the intervention. The registered trial corresponds to the Phase 3 randomised feasibility component; the qualitative phases provide the development and evaluation context.
