Injury Biomechanics

Motor Vehicle Accident Injury Biomechanics

Forensic Medicine Services include injury determination through the use of physics, science, crash forensic specific factors such as collision vector and risk factors, and provides an injury determination.  Injury biomechanics evaluates a mechanical force that occurs on an occupant's specific anatomical area.


This service is generally used for two purposes.  


The first is to prove injury.  In any motor vehicle collision, specific risk factors, crash factors and occupant reactions are known.  Thus by reviewing the crash forensics, an injury potential can be determined with a high degree of certainty.


The second benefit of this service is to provide a more specific and precise determination of injury potential.  At times, doctors can chase the pain.  However knowledge of chronic pain, neuropathic pain and muscular referral patterns combined with injury potential determinations allows for treatment of injury specific tissue, which can help to reduce the overall treatment duration due to increased specificity of treatment intervention. 



Epidemiological Risk Factors

Research has shown that a change in velocity during a motor vehicle collision of as little as 2.485 mph can cause injury.  For this reason, a singular analysis based solely of a force experienced by an occupant is NOT sufficient in order to determine and injury potential.


By the inclusion of epidemiological risk factors, in combination with crash forensics, occupant kinematics, and injury biomechanics a research based, scientific and medically sound determination of injury can be made.


Head Restraint Geometry Analysis

"For a head/seat restraint system to be effective good geometry is required. If a head restraints position is to far or to low to the back of an occupant's head, it can't prevent an injury in a rear-end collision. If the seat back is to stiff or the seat deflects to a greater angle, increased ramping of the torso can occur and lead to increased potential injury.  The Insurance Institute for Highway Safety researchers regularly evaluate the head/seat restraint system and occupant head geometry of head restraints and seat backs in passenger vehicles in order to determine injury potential and provide safety recommendations to improve occupant and vehicle safety in future crashes."

We review the crash data to determine if the head restraint geometry during the crash would have mitigated or exacerbated the force that the occupant was exposed to.  This will help in the determination of an injury potential based on collision research, crash forensics science and medicine.
