“Unlike a broken ankle, or other injuries you can feel with your hands, or see on an x-ray, a concussion is a disruption of how the brain works.” - USA Football & CDC
A concussion is like a 'brain sprain'. It's a brain injury caused by contact or twisting inside the skull.
Baseline testing is like a 'snap-shot' of pre-injury brain function. The ProAct Test is considered the gold standard.
With a ProAct Test an athlete can return to sport safely and quickly. Without it injury care becomes a guessing game.
