Most personal injury lawyers have represented clients suffering from the chronic consequences of concussion and musculoskeletal injuries following a rear end collision that caused minimal damage to the vehicles involved. This blog has reported on countless scientific studies showing that in some patients concussions can have long-term, chronic consequences. The standard defense employed by insurers in minimal damage rear end collisions (which they call “MIST” cases) is to argue that any injury is improbable in these accidents because the forces involved are similar to the forces involved in many activities of daily living (ADLs) where injuries rarely occur (like sitting down in a chair or sneezing.

The insurers and their defense counsel typically have an “accident reconstruction” expert they routinely use (often retired police officers) who calculate the speed change in the crash (the “delta V”) and then compare it to the delta V involved in everyday activities. (The delta V calculations by these so-called experts is often inaccurate, but that is a different issue.) Experience shows that this testimony can be very compelling to a jury, faced with judging the credibility of an injury victim whose injury is not immediately apparent. Read More
