I am thinking about thinking about trying to graduate from the walker. Have anyone of you made that journey? Did it involve retraining of some kind? At times I feel brave and think like the little engine that could. At night it is different. Energy low and much weight being on the handles of the apparatus. I have already been down the Physical Therapy road and the legs simply do not cooperate. Any other therapies out there? Any and all thoughts appreciated. Just wanted to get some opinions as I fear falling. TIA Ken in Texas.
