    • Component Modeling of the Lumbar Spine in Repetitive Flexion

 

A great deal of research has been devoted to prevention of low back disorders (LBD) and many possible causes have been postulated.  Among the external factors associated with the development of LBD, several are universally accepted, including manual material handling, repetitive bending, and the handling of heavy loads.  However, the exact combination of physical characteristics and loads that cause LBD is highly specific to an individual, and prediction methods remain to be developed. One path to an understanding of the etiology of low back pain is biomechanics.

The presentation will discuss the results of a recent study in which predictions of the mechanical response are determined for an entire lumbar spine exposed to realistic loads derived from the movement of human subjects, using a newly developed finite element model.  Stresses in multiple spine components due to cyclic loading through repeated sagittal lifts are determined, along with the motion of the spinal segments, considering nonlinearities, in both time and space, of the materials and motion.
