When assessing injury in patients after a MVA, should speed of the
impact be considered? Here is what Arthur Croft, DC, MS, MPH, FACO of
the Spine Research Institute of San Diego has to say:
“Here, the relationship between property damage and injury risk is
nonlinear. In the lower velocity range, vehicles are relatively stiff,
the collisions more elastic. In engineering parlance, there is a
relatively higher coefficient of restitution in lower velocity crashes.
Then, as crash velocity increases, so too does the amount of residual
crush of the vehicle. Interestingly, though, the actual risk to the
occupants decreases as this occurs. This has been demonstrated in
several studies. So, over this range of crash velocities, there is no
good correlation between injury risk, injury severity, or long-term
outcome and property damage. This is, of course, an important
distinction to understand.”
Here is an article which explains how insurance companies are
perpetuating the myth that injurie are not likely at low impact:

ACCIDENT

The research is overwhelming in showing that injuries and even death can occur in low impact crashes.
