It sounds like there was spontaneous return of function, which happens in various degrees following stroke anyway. Residual function plateaus about 1-2 years after on average, but this case would be an outlier.
I am more intrigued which med the physician prescribed, and whether there’s current research to support its use in post-stroke care as a neuroprotectant.
Its source is poor quality and there aren't many good sources otherwise, so it's still suspect. https://www.paleycenter.org/collection/item/?q=ryan&p=42&ite...
Several days after returning home I got stuck in the bathtub: I couldn't lift myself out, my wife couldn't lift me. After several false starts, we got me out by me lifting up a couple inches, and my wife shoving a pillow under my butt, several times. :-)
I was back at (office) work 2.5 months later, and biking to work 3 months after that.
All of which to say: 100% agreed -- do absolutely nothing and the body just wastes away.
