The Institute of Medicine in their recent report Relieving Pain in America: A Blueprint for Transforming Prevention, Care, Education, and Research states that: "Common chronic pain conditions affect at least 116 million U.S. adults at a cost of $560-635 billion annually in direct medical treatment costs and lost productivity." (IOM, 2011, p. 1) Pain is defined as "an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage." (IASP, 2011). This widely accepted definition suggests that there are multiple components in the experience of pain, namely physiological and psychological. Pain has been reported as the most frequently reported symptom in primary care, while chronic pain is reported to affect 20-30% of the population in Western Countries. (Verhaak et al, 1998). Individuals with chronic pain often report co-morbid depression, anxiety, decreased quality of life, activity restriction, and inability to work or engage in productive activities. The most frequently used therapies are pharmacotherapy and surgical interventions, both of which have limitations in their effectiveness and tolerability.
