Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Degenerative Scoliosis Group

This group comprised elderly patients (\>60 years old) diagnosed with degenerative lumbar scoliosis (DLS) (Cobb angle \>20°). Patients were excluded if they had concurrent neurological disorders, other spinal pathologies, or lower limb conditions that could influence gait mechanics. Additionally, individuals with a history of spinal or lower limb surgery were also excluded to minimize confounding factors.

Gait analysis and surface electromyography analysis

Intervention Type OTHER

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 cycles (5-meter walkway), enabling the quantification of both static postural control and dynamic gait characteristics.

Sagittal Imbalance Group

This group comprised elderly patients (\>60 years old) diagnosed with sagittal imbalance (PI-LL \>20° , SVA \> 4cm or PT \> 20°). Patients were excluded if they had concurrent neurological disorders, other spinal pathologies, or lower limb conditions that could influence gait mechanics. Additionally, individuals with a history of spinal or lower limb surgery were also excluded to minimize confounding factors.

lumbar spinal stenosis Group

This group comprised elderly patients (≥60 years old) clinically diagnosed with lumbar spinal stenosis (LSS) through radiographic findings and symptomatology. Exclusion criteria encompassed: (1) concurrent neurological disorders (e.g., peripheral neuropathy, cerebrovascular disease); (2) comorbid spinal pathologies (e.g., degenerative scoliosis, spondylolisthesis); (3) lower extremity conditions potentially impacting gait biomechanics (e.g., severe osteoarthritis, prior arthroplasty); and (4) any history of spinal or lower limb surgical interventions, thereby minimizing potential confounders.
