I hope it works for you! The one in PA has been great to work with. Gosh, Im not sure about bending over to undo an ankle strap that sounds very risky. You may be better off asking whomever it was that put you in that contraption. That's what I needed the aide for initially, helped with shower, meal prep and actually walked our dog when needed. My husband teaches at a University and it was very difficult for him to miss classes. Sometimes when I knew an aide was coming I would get them and have them pick me up junk food too. I think the minimum time limit is 2 hours.? But things may have changed.. I hope they can help you. Even for a "regular" THR I used them to help walk with me while there.. I just felt more secure, especially when I walked outside. I only needed them for less than 2 weeks but they never made me feel like I was a pain for not needing more.
