Abstract:
Understanding the relationship between repetitive lifting and the breakdown of disc tissue over several years ofexposure is difficult to study in vivo and in vitro. The aim of this investigation was to develop an asymmetric Porovisco elastic finite element model of a lumbar motion segment that reflects the biological properties and behaviors of in vivo disc Finite element predictions were compared to in vivo measurements published by Tyrrell et al. (1985) of percent change in total stature for two loading protocols, short-term creep loading and standing recovery and short-term cyclic loading with standing recovery. Future models will treat the tissues as poor-assume elastic and 3D in order to be more accurate and the relationship between repetitive lifting and disc degeneration.
