The Biomechanics of Vibration and Low Back Pain

• Description:
  The mechanical factors related to low back pain produced in an environment of vibration are reviewed. An apparatus was developed and tested for measuring the main and coupled motion, compliance, and viscoelastic response of a spinal motion segment to pure axial compression loading applied at or away from the subjects' balance point. The equipment allows one to test the effects of complex load environments or structural alterations of the motion segment. Sitting causes an extreme orientation for the lumbar intervertebral disc, increasing the internal pressure and the anteroposterior shear flexibility while decreasing the resistance to buckling instability and stressing the posterior region of the disc. The application of vibration to an already seated subject serves as an additional mechanical stressor. Several studies have indicated the need for preventive measures to be taken to minimize the vibration reaching the driver of a vehicle, to warn drivers not to attempt to lift or bend immediately following a driving period, and to encourage them to walk around for several minutes following a period of driving.
