I just finished reading a very good new book about low back problems and ways to prevent and rehab them. It is called "Low Back Disorders" by Dr. Stuart McGill, PhD. Dr. McGill is considered one of the world's leading experts on the biomechanics of the spine and the proper way to rehab injuries. In fact many of the world's leading athletes come to him in secret for help with their chronic bad backs. For over 20 years, Dr. McGill and his staff have studied the spine and have come to some surprising discoveries. For me the most eye opening is the damage that many commonly prescribed back rehabiliation exercises can do. The first part of the book is an engineer's dream as all of the research data is presented. You'll learn more about the spine and how it really works than you ever thought. Part 2 discussed ways to protect the spine during work and play. Part 3 shows how to diagnosis the specific problem area(s) in the low back, then how to develop a non-destructive program to strengthen and/or rehab an injured low back. Be warned, this is more textbook than general book, but Dr. McGill's writing style is well suited to the informed layman. While some of the hard science parts can be a bit obtuse, they present the important background data you need to understand why the specific diagnosis and rehab exercises work the way they do. If you struggle with low back problems or are interested in preventing them before they start, this is probably one of the best books you can read. I've read just about everything out there on the low back and this one definitely ranks in the top 3. You can find it at Amazon. He also has another book called "Ultimate Back Fitness and Performance" that I have on order. Will review once I've finished it.
