That's an amazing breakthrough and I'm not saying this is in any way a substitute, but a couple decades ago my parents were good friends with a guy who had Parkinson's and would often freeze when he was walking. I came across a study saying patients can get past the freeze by pointing a laser pointer at the floor in front of them. Just focus on the glowing dot on the floor and you can take a step. So they bought the guy a $5 laser pointer, and it actually worked for him. I'm guessing as he got worse it eventually stopped working, but I hope doctors haven't forgotten about that study.
