Aging is a universal process accompanied by significant musculoskeletal shifts, particularly spinal disc degeneration, which can severely compromise independent mobility. While spinal decline is a known hallmark of aging, the specific age-related threshold at which these structural changes manifest as substantive hindrances to gait remains a critical gap in biomechanical research.The primary aim of this project is to identify the age range at which disc degeneration impacts independent gait, with a specific focus on the hips, pelvis, and trunk. These segments form the functional link between the degenerating spine and the lower extremities. Using Statistical Parametric Mapping (SPM), this study evaluates continuous statistical differences in the angles, moments, and power of the hip, pelvis, and trunk between two cohorts: individuals below 65 years and those above 65 years.By analyzing the kinematic and kinetic data across the entire gait cycle, this research seeks to pinpoint precisely how and when spinal degeneration alters core stability and proximal joint function. The findings will provide essential data for developing targeted physical interventions aimed at preserving gait integrity and prolonging functional independence in the elderly.
