The last section about generalizing the treatment is a bit underwhelming. Have they seen any evidence it can be used outside this sort of repair? What about for neuropathies, as from diabetes or surgeries? Stroke? Other dysfunctions (e.g. erectile/genital) having nervous system issues as a contributing factor?

Any treatment "might" have more general applicability--but surely there is some specific direction/class of these conditions that are indicated to be more appropriate to apply the treatment to than others. I wish they'd gone in more depth here.
