But what's fascinating about Mackenzie, sometimes even in the room, they'll get reduction of nerve symptoms while they're in that position. And so, nerves provide very like productive information. like you can trust symptoms of a nerve really well. So if I get what they call a centralization, meaning I had sciatic pain all the way down the leg and then you put me in this one McKenzie position and now it centralizes to the hamstring, that's a great indicator.
