“Bio mechanical researchers have long understood that rotational forces, not linear forces, are responsible for serious brain damage. Including concussions, brain injury complications and brain bleeds.” (55)
Rotational acceleration is defined as “when the head comes to a sudden stop, if it’s rotating, and the brain material is twisting inside the head and that can cause concussion and brain injury.” (56)
Dr. Christopher Giza, MD pediatric neurology and neurosurgery at UCLA stated “there is no helmet that is going to prevent your head from moving, helmets can probably reduce the rate of concussions by dampening the forces, but they are not going to be able to immobilize the head. There would be no such thing as concussion-proof helmet”. (57)
