Is this trial a fit for you?

Likely a good fit

Ideally, English-speaking adults with axial spondyloarthritis who are insufficiently active and willing to use a Fitbit and Google Health app.

Probably not a fit

Patients who are unable or unwilling to participate in regular exercise or use the required digital tools may not benefit.

What this trial studies

This interventional study evaluates whether using the ExerciseRx mobile app, which provides guided exercises and weekly step goals, is practical and beneficial for people with axial spondyloarthritis. Participants perform 20–30 minute guided exercise sessions four times per week and aim for personalized activity goals while wearing a Fitbit. Outcomes are compared to a usual-care group to see changes in symptoms, physical function, and disease activity. The study requires English-speaking adults with axSpA who are insufficiently active and have internet access throughout the study.

Why it matters

Potential benefit: If successful, the app could help patients maintain regular exercise and improve symptoms and function.

How similar studies have gone: Previous digital health and app-based exercise programs have shown mixed but promising results for musculoskeletal conditions; this study builds on that approach in axSpA.
