A Digital Exercise Intervention in Patients With Spondyloarthritis

This protocol describes a 6-month randomised, controlled exercise trial in patients with axial spondyloarthritis (axSpA) with re-randomization after 3-months. The primary outcome of the trial (disease activity) will be evaluated at 3-months. The exercise programme on trial comprises high intensity interval training (HIIT), muscular strength exercise and aerobic physical activity sessions of specified duration, frequency, and intensity. It also includes brief knowledge videos to empower the patient. The intervention is remotely delivered by the SPARK application with personalised follow-up including monitoring to ensure exercise progression and adherence to exercise intensity. The SPARK application is built on a platform delivered by ABEL Technologies (trademark) and is customised for patients with axSpA.
