Energy criterion in the assessment of damping of a spinal motion segment subjected to cyclic loading

摘要

The primary functions of the spine, and in particular the intervertebral disc, are to support transfer of loads, permit motion, and dissipate energy in the spine. The objective of this study was to analyse changes in damping of a spinal motion segment subjected to cyclic loading using the energy criterion. Another important aspect of the undertaken study was an evaluation of the impact of posterior spinal column elements, i.e. articular processes joints on changes in energy dissipation by the intervertebral disc.
