I had 3 broken ribs, one was shattered. I have used infrasonic 9 [Latest Version is CHI-Palme] several times a week for 30 minutes at a time. The Dr. had told me that it would take at least 8 weeks to get back to my activities and that he had no guarantee on the shattered rib. After only 4 weeks the X-ray showed that my shattered rib was indeed healing and I was able to begin gentle swimming and yoga again!! I give credit to the Infratonisch 9 treatments!  5 out of 5 stars
