An ABI is a complicated thing, and the effects upon your life can be really far reaching. Now, is a supermarket automatic door opener enough to cause that much injury? Mmm, possibly. I've seen them when they open like a regular swing door and they've been up too high (or whatever) and slam open. They're heavy and forceful. So if that happened and it also knocked her back down onto a concrete floor where she hit her head? I could see serious long lasting injury coming out of that to be honest. Now it remains to be seen how bad the accident really was of course. But I've had those doors hit me on the arm or shoulder before (usually when slow moving people don't get out of your way fast enough-why do people enter a room or building and just come to a dead stop anyway? Argh!) and it left a substantial bruise.
