I just googled it. It kind of sounds like slow massage of specific places, not muscles, I'm not sure where but I'll find out. There is a place that does MFR 1/2 a mile from me (I'm in Bethany Beach, Delaware). I said I would try anything, I will try it. I'll call them tomorrow - I'll let you know how it goes. I've been a guinea pig in more difficult situations than getting a massage ... Peggy
