Changes in range of motion (ROM) at segment L2–L3 (UIV/UIV + 1) after stepwise dissection of the posterior ligaments (L4–L6, L3–L6, L2–L6), normalized to the initial flexibility test as basis (intact_cycl) in percentages, after preconditioning by cyclic loading. * Significant at P < 0.05, ns: not significant
