Worked great for me. Big recommend. "Cured" is mostly an unspecifiable state, and while certainly there's lots still wrong with me, I am healed far beyond my expectations at the outset, so increment your count by one.
Is a person with a crutch healed? No. But they can walk, when before they could not. Therapy can't erase the past, but it can give people tools to live more capable and rich lives. A crutch doesn't regrow an amputated leg, but it does help that person handle the injury, so in that sense, it 'works'.
