Spinal posture helps crash response evaluation of reclined occupant

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.
