High intensity interval training safe in PsA

Key clinical point: The 11-week high intensity interval training (HIIT) regimen had no influence on the bone marrow edema (BME) in patients with psoriatic arthritis (PsA).

Major finding: After 11 weeks, similar proportions of patients in the HIIT and control (no changes in exercise regimen) groups had BME changes, as assessed by a radiologist (P  =  .5) and SpondyloArthritis Research Consortium of Canada scores (P  =  1). Although the values of 20 textural features were significantly different in the voxels of BME vs healthy bone marrow (P < .001), the textural features of PsA lesions were similar between the HIIT and control groups (P > .2).

Study details: Findings are from the analysis of a part of a randomized controlled trial including 37 patients with PsA who performed HIIT 3 times/week for 11 weeks or followed the control regimen and were evaluated by MRI.
