Exercise Therapy in Patients With Axial Spondyloarthritis

Patients allocated to the exercise arm will be prescribed a home-based walking exercise programme consisting of 30 minutes of walking on 5 days per week at an RPE in the range of 12-14 (somewhat hard). Each patient's heart rate range will be established during the baseline exercise test by recording the heart rate response at the required RPE target range. This will be provided to each patient to use in conjunction with the activity monitor they will be given to wear on their non-dominant wrist. The monitor reports heart rate and records daily steps, distance and activity duration.
