I've had this bad habit since I was a child. Even as a grown adult I still have the dumb habit of racing up and down stairs at home like I did as a kid. And predictably I'll trip several times per year doing it. Tonight I was running at a sprint's pace upstairs in a hurry as I forgot something on the way out the door and missed the top step, so I caught my toe on the edge of the stair; fell forward and landed on my hands, with my head getting jerked back into my traps/shoulders region.

Is it really tough to get a concussion this way without a direct blow to the head? People talk of injuries where the head does not come in direct contact with an object and still receiving a concussion. Would it take a pretty severe 'whipping' style motion from a trip to do permanent damage?
