This is an observational study using Inertial Measurement Unit (IMU) sensors to measure the effects of biological therapy on spinal mobility and function in axial spondyloarthritis. Participants will undergo MRI scans before and after therapy in parallel to the sensor tests to establish correlation between changes in inflammatory signs and changes in spinal mobility.
We will study 20 participants with active axial spondyloarthritis (axSpA) who are about to start biologic therapy as part of routine care. In brief, we will carry out the following assessments before and after therapy:
