The analysis focuses on spatiotemporal gait characteristics (step length, stride length, cadence), lower limb kinematics and kinetics (hip\u002Fknee\u002Fankle 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.",[26,27,28,29,30,31,32,33],"Adult Spinal Deformity","Degenerative Scoliosis","Sagittal Deformity","Sagittal Imbalance","Coronal Vertical Axis","Lumbar Spinal Stenosis","Lumbar Disc Herniation","Cervical Spondylosis With Myelopathy","NOT_YET_RECRUITING","2025-12-15",{"date":37,"type":38},"2025-12-30","ACTUAL",{"date":40,"type":22},"2025-12-10",{"date":42,"type":22},"2029-12-01",{"name":44,"class":45},"Xuanwu Hospital, Beijing","OTHER",1,{"id":48,"slug":49,"hasResults":11,"nctId":50,"briefTitle":51,"officialTitle":52,"acronym":53,"eligibilityCriteria":54,"healthyVolunteers":11,"sex":18,"minAge":55,"maxAge":4,"enrollmentInfo":56,"targetDuration":4,"studyType":58,"phases":59,"briefSummary":61,"conditions":62,"keywords":4,"overallStatus":34,"whyStopped":4,"lastUpdateSubmitDate":64,"lastUpdatePostDateStruct":65,"startDateStruct":67,"completionDateStruct":69,"leadSponsor":71,"locationsCount":46},"100552212","a-novel-classification-of-sagittal-spinal-alignment-to-aid-surgical-planning-for-adult-spinal-deformity-100552212","NCT06470152","A Novel Classification of Sagittal Spinal Alignment to Aid Surgical Planning for Adult Spinal Deformity","Pelvic Incidence-Dependent Clustering of Sagittal Spinal Alignment: A Novel Classification to Aid Surgical Planning for Adult Spinal Deformity","CSSAASD","Inclusion Criteria:\n\n1. ≥ 18 years of age at the time of treatment;\n2.
