Sagittal balance dynamics during gait in patients with degenerative spine disease

Abstract Study Design Observational Case–Control Study. Purpose To evaluate the dynamics of sagittal balance during gait in patients with degenerative spine disease compared with matched controls. Methods 33 patients with pathological sagittal balance parameters on standing radiographs and 31 matched controls underwent three-dimensional motion capture analysis during a six-minute walking assessment. Data were collected across five phases: pre-walk, initial-walk, mid-walk, end-walk, and post-walk
