(From inside front cover) Dr, Alec Thompson is one of the best-known back men on the West Coast. In 1971, he discovered a very simple exercise which would enable a patient to correct his own back trouble or, in many cases, prevent its recurrence. Dr. Thompson firmly believes that the root of the trouble usually lies in the misalignment of the sacroiliac joints, a condition that often causes trouble not only in the back, but in the neck, the head, and even in the sinuses. He is firmly against operating except in very unusual cases. He doesn't believe in traction, prolonged bed rest, pills, or heat. What he does believe in is so easy and, in many documented cases, so effective that back-sufferers everywhere stand to find in this book---with its clear, how-to photographs---what they have long been seeking---an end to pain.
