Study Details

Brief summary:

The purpose of this study is to find out whether a mobile app called the ExerciseRx app is a practical and helpful way for people with axial spondyloarthritis (axSpA) to receive exercise recommendations as part of their regular rheumatology care.

Researchers want to learn:

Whether people with axSpA find the ExerciseRx app easy to use and helpful for supporting regular exercise.

Whether using the ExerciseRx app leads to improvements in symptoms, physical function, and disease activity compared with usual care.

Participants assigned to the ExerciseRx group will use the app to complete guided exercises for 20-30 minutes, four times per week. They will also receive personalized weekly step-count goals to help increase their physical activity. Researchers will compare outcomes between participants using the app and those receiving usual care.

Interventions and Outcome Measures

Arms

experimental: ExerciseRx app

the ExerciseRx app with personalized exercise recommendations, an educational handout, Fitbit-guided step goals, and physical therapy referral

active comparator: Usual care

An educational handout, Fitbit monitoring without step goals, and physical therapy referral

Interventions

Physical activity program intervention

Patients complete home exercise sessions given via the ExerciseRx app over 20-30 minutes 4 times per week for 12 weeks and receive daily step count goals. Patients also receive a FitBit to wear continuously throughout the study, and are given access to view their step counts via the ExerciseRx app, and receive an educational handout with exercises for axial spondyloarthritis.

Usual Care Group

Patients receive recommendations from their physicians to continue their usual physical activity as tolerated, receive a FitBit to wear continuously throughout the study, with the ExerciseRx app locked to the baseline home screen, and receive an educational handout with exercises for axial spondyloarthritis.

Primary outcome measure

  • Average minutes of physical activity/exercise during the week and % of participants with adherence to 60% or higher of the recommended exercises [ Time Frame: Week 0 (baseline), 6 and 12 ]
  • Acceptability of the ExeriseRx app as a platform to complete recommended exercises for axial spondyloarthritis including % of participants with average score above 5 on MAUQ indicating usability [ Time Frame: Weeks 6 and 12 ]
