Modeling and Simulation of Human Lumbar Spine

摘要

The objective of this collaborative research is to develop a computer modeling and visualization environment that is capable of simulating the three dimensional static and dynamic motion response of the lumbar spine. We have developed a parameter estimation routine that uses genetic algorithms to systematically identify stiffness and damping properties that can accurately predict spine segments motion. The ensuing computer simulation and modeling program is tested with experimental displacement-time and acceleration-time spine motion data. Experimentally-optimized stiffness and damping properties derived from the model are used to characterize the normal and pathologic spine. This work provides a tool for diagnosis of spinal disorders and will assist chiropractors and researchers in understanding the mechanical response of the human spine to external forces. It will also provide important biomechanical information and visualization tools that can be used to assist in the diagnosis and treatment of spinal disorders, including low back pain.
