Using sensors to assess spinal mobility in patients with axial spondyloarthritis

An Investigation Into the Responsiveness of Inertial Measurement Unit (IMU) Sensor-based Tests in Measuring Changes in Spinal Mobility and Function in Axial Spondyloarthritis Patients Treated With Biologic Drug

Observational Western Health and Social Care Trust · NCT04489342

This study is testing how a new treatment for axial spondyloarthritis affects spinal movement and function in people starting biologic therapy by using special sensors to track changes.

What this trial studies

This observational study evaluates the impact of biological therapy on spinal mobility and function in patients with axial spondyloarthritis using Inertial Measurement Unit (IMU) sensors. Twenty participants who are about to start biologic therapy will undergo MRI scans and various patient-reported outcomes before and after treatment. The study aims to correlate changes in inflammatory signs with improvements in spinal mobility as measured by both clinical assessments and sensor tests. This comprehensive approach will help in understanding the effectiveness of the therapy.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 80 with a diagnosis of axial spondyloarthritis who meet local criteria for biologic therapy.

Not a fit: Patients with severe hip movement restrictions, previous spinal surgeries, or contraindications for biologic therapy or MRI assessments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the effectiveness of biological therapies for improving spinal mobility in axial spondyloarthritis patients.

How similar studies have performed: While the use of IMU sensors in this context is relatively novel, similar studies have shown promise in assessing mobility and function in other rheumatological conditions.
