Using Xsens wearable sensors to measure lumbar spine movement fluidity before and after rehabilitation
Official title: Xmouv - Assessment of the Evolution of Lumbar Spine Movement Fluidity Using Xsens Inertial Sensors in Subjects With Chronic Low Back Pain Before and After Rehabilitation
Run by University Hospital, Montpellier · NCT07327554 · Data updated 2026-11-12
This project will try whether wearable Xsens sensors can detect improvements in lumbar spine movement smoothness in adults aged 18–65 with chronic low back pain who undergo rehabilitation.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18–65 with chronic low back pain lasting more than three months, BMI 18–30 kg/m², who are receiving rehabilitation care at Montpellier University Hospital and can give informed consent are ideal candidates.
✕Probably not a fit
Patients with recent sciatica episodes, traumatic/tumoral/infectious causes, prior lumbar arthrodesis, inflammatory rheumatism, severe scoliosis, pregnancy, BMI outside 18–30, or who cannot attend in-person visits are unlikely to benefit from the measurements in this project.

What this trial studies
The project uses 3D biomechanical analysis with Xsens inertial sensors to record lumbar spine motion during flexion before and after a prescribed rehabilitation program at Montpellier University Hospital. Investigators will quantify movement fluidity by identifying brief disturbances called "jerks" and compare those measures to clinical outcomes. Eligible participants are adults 18–65 with chronic low back pain and BMI 18–30 kg/m² receiving rehabilitation care at the site, with exclusions for recent sciatica, spinal fusion, inflammatory disease, severe scoliosis, pregnancy, and other criteria. The goal is to correlate changes in objective kinematic metrics with patient-reported and clinical improvements following rehabilitation.
Why it matters
Potential benefit: If successful, this approach could provide an objective, wearable-based measure to track functional recovery and help tailor rehabilitation for people with chronic low back pain.
How similar studies have gone: Prior kinematic studies have examined range of motion, lumbopelvic rhythm, and movement variability with mixed and inconsistent results, while movement fluidity quantified by jerks is relatively novel and under-studied.
