Dr. Altrocchi, a low back pain MD-expert, directs his book to the 250 million people who have had, now have or will have lumbar back pain. The traditional MD-approach emphasizing "herniated discs," "pinched nerves" and surgery, has failed for 75 years, causing widespread chronic back pain, disability and human tragedy. In fact, over 90% of back pain is caused by mechanical spine problems, easily diagnosed and treated by logical, anatomical hands-on methods, clearly explained by Dr. Altrocchi, a former Professor of Neurology at Stanford Medical School with 40 years of clinical experience. If patients are seen immediately, they can be cured promptly by simple, logical, non-painful manual treatment without expensive, misleading scans which too often lead to useless and harmful surgery.
