I bought the two volume set several years ago. It paid for itself the first time I used it and was able to get a severe headache under control at home, instead of going to the emergency room. Yes, even with a killer headache or back spasm, the book is easy to use, although it's got enough technical detail to make it an essential reference in any physician's library.

I bought these books (upper and lower extremeties)to help me with trigger point work in the neck and shoulders, especially the scalenes and rotator cuff and to gain more knowledge with other major muscle groups. What I ended up with was a wealth of information, more than I could ever have dreamed of, these books are beautiful, wonderful color illustrations. Clear and easy to follow. There is also information on different stretches and how to educate and help the client. I will have these books for the rest of my life.

It is a wealth of information that I will enjoy for a lifetime.
