Vibration Characteristics of the Human Spine Under Axial Cyclic Loads: Effect of Frequency and Damping

Abstract

The posterior regions of intervertebral discs of the lumbar spine are easy to injure during long-term whole body vibration compared to anterior regions. The vibration of human spine is more dangerous to facets, especially during whole body vibration approximating a sympathetic vibration, which may lead to abnormal remodeling and disorder of the lumbar spine.
