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
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.

Healthy Volunteer Group
This group comprised healthy elderly patients (≥60 years old) . Exclusion criteria encompassed: (1) concurrent neurological disorders (e.g., peripheral neuropathy, cerebrovascular disease); (2) comorbid spinal pathologies (e.g., degenerative scoliosis, LSS, LDH, 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.
