The objectives of this study were (1) to quantify changes in the mechanical behavior of the intervertebral disc in response to cyclic compressive loading and (2) to determine whether mechanical behavior would be restored following a period of unloading. The elastic and viscoelastic compressive mechanical behaviors of adult sheep motion segments were assessed. Ten thousand cycles of compressive loading resulted in increased elastic stiffness and decreased stress-relaxation. After 18 h of… CONTINUE READING
