ABSTRACT
Pain is an unfortunate daily experience for many individuals. Chronic pain, lasting 6 or more months, is suffered by approximately 30% of the U.S. population (Bonica, 1990). These individuals wake up, function during the day, and go to sleep trying to keep pain at a minimum while, at the same time, maintaining some quality of life. They may be frequent visitors to the doctor and the pharmacy. When they find relief it is usually short-lived and comes at a cost, such as dependence on narcotic medications or complete limitation of activity. Pain often becomes the central point of their existence.
