Query: Excellent book

I have used the book as a quick reference / exercise guide and to learn about ART treatment. I am absolutely delighted with the book for helping me avoid surgery for my Carpal Tunnel Syndrome injury. Most stiffness problems seem to be cured by simple sustainable stretching exercises which are the backbone of this book.Great book and the material is organized in an easy to read layout with a chapter devoted to each of the common problem areas like Carpal Tunnel Syndrome / Elbow / Shoulder / Plantar Fasciitis / Knee Injuries, etc.
