Fig. 9From: Effects of resting modes on human lumbar spines with different levels of degenerated intervertebral discs: a finite element investigationComparison of the changes of the disc fluid loss subjected to different load cases for all models. The fluid loss could reflect the capacity of convective transport of solutes within the intervertebral disc, and low fluid loss is closely related to disc degeneration. a Grade 0, b Grade 1, c Grade 2, d Grade 3Back to article page
