Key Points

  • To assess how subject-specific spinal postures affect crash response evaluations and spinal injury risk.
  • Utilized THUMS models with individual spinal postures.
  • Compared predictions of Z-direction kinematics between specific and generic models.
  • Analyzed correlations between spinal kinematic and kinetic responses.
  • Improved predictions of Z-direction kinematics with specific spinal postures.
  • Established correlations between spinal responses and injury risks.
  • Provided insights into lumbar injury mechanisms for reclined occupants.

Abstract

THUMS models incorporating subject-specific spinal postures provide improved prediction of Z-direction kinematics compared to generic models and enable preliminary evaluation of spinal injury risk. Additionally, correlations established between thoracolumbar spine kinematic and kinetic responses offer new insights into lumbar injury mechanisms for reclined occupants.
