The Effect of Vibration and Posture on the Progression of Intervertebral Disc Herniation

In Brief Porcine vertebral discs were partially herniated and subsequently exposed to vibration and shock loading. Vibration and shock loads lead to disc herniation exacerbation. In this exacerbated disc damage, flexion of the motion segment under vibration did not worsen the nucleus tracking although did make the disc marginally stiffer.
