简要总结
Low back pain, defined as pain located between the thoracolumbar junction and the lower gluteal fold, becomes chronic in 8% of patients. As the leading cause of disability worldwide, it has major individual and medico-economic consequences.
Three-dimensional biomechanical analysis allows exploration of movement alterations related to low back pain. Although several parameters have already been studied (maximum joint range of motion (ROM), lumbopelvic rhythm, movement variability, gait), no consistent kinematic profile has emerged. Movement fluidity, assessed by the presence of jerks (brief movement disturbances), remains under-described despite its relevance in evaluating movement quality.
Invistigators hypothesize that lumbar spine movement fluidity during flexion improves after a rehabilitation program and correlates with clinical response.
This project stands out by exploring a rarely studied parameter (movement fluidity) and integrating it as a potential indicator for rehabilitation monitoring.

Correlation between the evolution of trunk flexion movement fluidity and the evolution of disability before and after rehabilitation program
时间窗: 2 weeks
Movement velocity will be measured during flexion using Xsens inertial measurement units (head, T8, L1, L4, S1). Velocity profiles will identify acceleration and deceleration phases. Movement fluidity will be quantified by a normalized jerk metric: the count of local minima and maxima on the angular velocity curve divided by flexion/extension duration (peaks/s). This normalization accounts for variations in movement speed between individuals and measurement sessions, providing a standardized measure of movement smoothness where lower values indicate more fluid motion. Disability will be measured by the change in the score of Oswestry Disability Index (ODI) questionary between the first and last day of rehabilitation. The ODI questionary contains ten topics concerning intensity of pain and activities of daily life. Each question is scored on a scale of 0-5 where zero indicates the least amount of disability and 5 indicating most severe disability. The ODI scale range from 0 to 100
