Official title
Comparative Analysis of Spatiotemporal Gait Parameters and Paraspinal Surface Electromyography Parameters in Degenerative Spinal Diseases: A Cross-Sectional Study Using Motion Capture and Electromyographic Ensemble Averaging
Overview
This cross-sectional observational study aims to quantitatively compare three-dimensional gait parameters, surface electromyography (EMG) patterns, and radiological parameters among patients with different degenerative spinal conditions-including lumbar disc herniation (LDH), lumbar spinal stenosis (LSS), lumbar sagittal imbalance (LSI), degenerative lumbar scoliosis (DLS), and cervical spondylotic myelopathy (CSM)-alongside a healthy control group. The analysis focuses on spatiotemporal gait characteristics (step length, stride length, cadence), lower limb kinematics and kinetics (hip/knee/ankle joint angles, moments, and powers during stance and swing phases), and surface EMG amplitudes (thoracic erector spinae, multifidus, gluteus maximus, and rectus abdominis muscles) during standardized walking tasks. Additionally, radiological parameters (e.g., pelvic incidence-lumbar lordosis mismatch, C2-C7 sagittal vertical axis, coronal Cobb angle) will be correlated with gait and muscle activation deviations. The study employs motion capture systems, force plates, and high-density EMG to objectively differentiate disease-specific movement impairments. Findings from this study may establish biomechanical and neuromuscular signatures for each degenerative condition, providing a framework for personalized rehabilitation strategies, gait retraining, and surgical outcome assessment in spinal disorders. Comparative analysis with healthy controls will further elucidate pathological alterations in gait and muscle recruitment patterns caused by degenerative spinal diseases.
Interventions
- Other Gait analysis and surface electromyography analysis
A comprehensive motion analysis system was employed to assess biomechanical parameters during functional tasks. Ground reaction forces (GRFs) were measured using an instrumented force plate, while muscle activation patterns were recorded via surface electromyography (sEMG). Three-dimensional kinematic data were concurrently captured using motion-capture cameras. The standardized testing protocol consisted of: (1) quiet standing (30-second trial) and (2) three consecutive back-and-forth walking c
