The Effect of Posture on Forces and Moments Measured in a Hybrid III ATD Lower Leg.

CONCLUSIONS: The range of postures tested herein spanned published injury criteria, and thus would have made the difference between pass and fail in a safety evaluation. In/eversion had the largest influence on injury metrics, likely due to the change in axial stiffness and altered impact durations in these postures. Results suggest increased injury risk at neutral or near neutral postures, whereas previous cadaveric studies have suggested that in/eversion does not influence injury risk. It is unclear whether the ATD appropriately represents the natural lower leg for impacts in out-of-position testing. Great care must be taken when initially positioning ATDs for safety evaluations, as small perturbations in posture were shown herein to have large effects on the measured injury risk using this tool.
