Forensic Medicine 

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.

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.

  • Analysis of Injury Biomechanics in Combination with know Risk Factors in order to determine Injury Potential
  • Acute Injury Risk
  • Chronic Injury Risk

Brain Injury Analysis

Brain Injury Occupant Kinematic Analysis

Motor vehicle collisions result in specific forces occurring on the occupants spine and head. These forces are specific to the crash vector and occupant reaction. By evaluating the crash forensics of the crash, a correlation between injury potential and injury sustained can be determined.

  • Direct Contact
  • Coup Counter Coup
  • Pressure Gradient Changes

Neck Injury Analysis

Motor Vehicle Collisions result in specific forces occurring in the Cervical Spine. In a collision a number of forces can be present, 

however the collision vector, risk factors and occupant reaction with the vehicles restraint system will dictate what forces act on the cervical spine.This Injury Biomechanics knowledge in correlation with Anatomy, Neurology and Pain concepts allows for an injury potential determination based on research, science and medicine.
