All data are shown as mean (SD).
DBS: deep brain stimulation, C7SVA: C7 sagittal vertical axis (mm), Cobb: Cobb angle (degrees), LL: lumbar lordosis (T12-L5, degrees), PI: pelvic incidence (degrees), PT: pelvic tilt (degrees), SD: standard deviation, SS: sacral slope (degrees), TK: thoracic kyphosis (T5-T12, degrees).
