Excellent book
I had a serious back injury 3 monthes ago. I had severe sciatic pain and muscle spasms due to herniated L-4, L-5 S1. My Dr. reviewed the MRI and referred me to physical therapy and a orthopaedic surgeon. He said I could have epideural injections also to relieve the pain. Thankfully a PA referred me to this book, and I followed the exercises religiously, doing the repetitions several times daily. Last week I was able to go on a moderate hike and even jog part of the way. I'm about 95% pain free now! Of course, I know that God healed my back in response to prayers and I praise him for his healing touch, but I also know that God uses people like Robin McKenzie to help us do our part to recover and know how to maintain wellness.
