Fig. 8From: Effects of resting modes on human lumbar spines with different levels of degenerated intervertebral discs: a finite element investigationComparison of the changes of the radical displacement subjected to different load cases for all models. The radial displacement is closely related to disc degeneration. The maximum changing magnitude in radial displacement was not obvious in comparison with the changing magnitudes in axial effective stress and pore pressure. a Grade 0, b Grade 1, c Grade 2, d Grade 3Back to article page
