As I said, I'm no brainguy or medical person whatsoever. But, my completely uneducated understanding is "yes". For example a shirtfront would be a sudden stop to the body, but absorbed by the body a bit and the stop to the head not necessarily as severe as if the same contact had been to the head.Genuine question because I am clueless. If it is all on rapid acceleration/deceleration and nothing to do with impact, could a concussion be caused by a sudden stop to the body or is that whiplash action of the head that enables the brain to slow more naturally? What about if you are headbanging and suddenly stop?
Whiplash in car accidents etc can cause concussions - obviously this is at a more extreme deceleration than a football collision would normally be.
Happy to be corrected by anyone with even a small amount of knowledge.
