Evaluating Changes in Lumbar Spine Movement Fluidity Using Xsens Sensors in Adults With Chronic Low Back Pain Before and After Rehabilitation

What this Trial Is About

Low back pain, defined as pain between the thoracolumbar junction and the lower gluteal fold, becomes chronic in 8% of patients and is a leading cause of disability worldwide with significant personal and economic impact. This research aims to study changes in lumbar spine movement fluidity, a less explored parameter, before and after rehabilitation in people with chronic low back pain. The study focuses on how movement fluidity during trunk flexion improves and relates to clinical outcomes after treatment. Participants will have their movement assessed using five Xsens inertial sensors placed on specific points of the spine and head to record kinematic data during standardized lumbar spine movements. These measurements will be taken before and after a two-week rehabilitation program conducted in a hospital setting. The study evaluates the evolution of movement fluidity alongside other movement parameters and clinical factors during this rehabilitation period. Throughout the study, participants will perform standardized tasks involving lumbar flexions and rotations while wearing the sensors. Researchers will measure changes in movement fluidity, range of motion, pain, disability, psychological impact, and muscle endurance before and after rehabilitation. The primary outcome is the correlation between trunk flexion movement fluidity and disability changes over two weeks. The total participation duration corresponds with the rehabilitation program length and assessments before and after this period.
