@birdman Mitch, Understandable. You can do similar movements sitting on a large therapy ball too as if you are riding a horse and you can put one hip forward and then the other to simulate walking hip movement. I also have an inflatable seat cushion that does the same thing like a therapy ball, and I used to sit on that wiggling around and working my back. Hopefully you'll get to do some PT soon. Walking is great too for back muscles if it helps.
