I suspect this in not one either.
I agree.
It doesn’t seem to make the patients good as new, plus there’s no telling how long before the injection wears off.
What if one would need a new injection in the neck every hour or so, followed by a period spent upside down?
Plus, it’s possible that repeated injections over time could begin to lose effectiveness.
But the best part is this study shows that some function can be restored, i.e., that it had not been forever destroyed.
