So Simple It’s Stupid

I have posted many a video about concussions here on the blog but this one (thanks to Tommy Dean) may be the best for its pure simplicity and message about management;

People need to understand that concussions don’t have to involve a hit to the head.  I have seen throngs of people on Twitter and other places not grasping this.  Perhaps none more so in the product development sector; those very intuitive people with good ideas that think protecting the head will reduce concussions.  Be it a helmet addition, or better helmet, or those that want to remove helmets from the game, what they fail to grasp is that linear hits to the head with linear forces alone do not constitute the majority of concussion sequale.  The concussion comes as a result of a constellation of factors; the biggest of which is the acceleration/deceleration of the head, followed closely by the shearing (due to angular and rotational forces) of the head.  If you notice most mechanisms of injury one would easily note that knocks to the head with limited movement of the head itself, are not the vast majority of concussions seen.  The hits a person takes in sports and LIFE that are unanticipated and have multiple vectors is where we get a lot of concussions from.

For a better visual, if I were to say to you I am going to punch you in the face from the right side, and you had a chance to brace for it, there is a good chance you could absorb that blow with little to no problems.  However if I were to not say a word and walk up and hit you in the same spot with the same force, the chances you will be “hurt” are much greater.  When you anticipated the hit you would have braced and made the force almost strictly linear, with little rotation due to your neck muscles…  Where as, the sucker punch would move your head sideways and back; quickly accelerating your head then suddenly it would be decelerated by the spine range of motion limits.

I hope this has provided some positive learning for everyone…
