Update, one year after second treatment: Legs are a lot stronger and getting bigger! A little bit more range of motion and sensation in the right leg, still have trouble moving the ankle though. Standing, balance, and endurance has improved very much, I can walk longer distances faster without getting as tired. At the gym I can even use the leg press on my own now, my right foot doesn't slip off on its own anymore so I have more control in that leg now. A few months ago I was not able to push it at all, now I can do it and even add a little weight onto it. Still practicing with the cane and hoping to lose the crutches for good haha. Working hard every day still and hoping for more improvements :)
