This week, we take a look at Whiplash Injury or Concussion? A Possible Biomechanical Explanation for Concussion Symptoms in Some Individuals Following a Rear-End Collision from the Journal of Orthopaedic & Sports Physical Therapy. Elkin, et al. 2016 provide their biomechanical explanation for mechanism of injury of a concussion in a rear-end type collision. These authors specifically are looking at impact forces with head seat restraints compared to head blows (direct) that are known to cause concussions (contact related sports). Study data was compiled using simulated brain/head models and corroborated some clinical trends we typically see in our MVA patients:
