I read up on it years ago and had a few of the PT massages that goes with it. For me it never did work. They could put pressure on the points but it would only trigger all kinds of chain reaction spasms/cramps in my muscles. No matter how long they did it or how hard or soft they did it. I gave up on massages working. Hubby will do massage on a cramping muscle...sometimes it will work for the one, most of the time it doesn't work.
Hot tub does pretty good but I can no longer get out of them by myself.
