Wow! My back had completely locked up before I got to the Woodlands, and I was doing everything I knew to help it get better. I was able to receive a P-DTR session from Dutch Thomson while I was in the Woodlands, still recovering, and the difference was instantly noticeable. I did not understand how some of my muscles that had not released in the last 10 days instantly released. I could feel them let go. I couldn't tell you how things worked, but just that it did. When I got back in Cincinnati, my PT said he could tell a noticeable difference.
