Low-back pain continues to impose a huge burden on industrialized societies, in terms of symptoms, medical costs, productivity, and work absence. Annual costs related to back pain in the United States alone may run as high as $100 billion per year.



But a systematic review of the literature for high-quality scientific trials published in the February issue of The Spine Journal finds exercise in workplace and community settings effective in preventing new episodes of low-back problems. "Strong and consistent evidence finds many popular prevention methods to fail while exercise has a significant impact, both in terms of preventing symptoms and reducing back pain-related work loss," said Dr. Stanley J. Bigos, University of Washington professor emeritus of orthopaedic surgery and environmental health.
