Introduction: Fibromyalgia is an extremely disabling condition associated with chronic widespread musculoskeletal pain and reduced pain thresholds (Wolfe et al., 2010) (Kelley et al., 2011). Observational studies have shown that over a 12-month period, 25% of men and women surveyed over the age of 65 will consult a primary care physician for musculoskeletal pain (Jordan et al., 2010). Overall, between 46% and 80% of people over age 65 report experiencing pain daily, and 15% of women and 10% of men over age 50 report widespread musculoskeletal pain (Soldato et al. , 2007; Thomas et al., 2004). The Centers for Disease Control and Prevention estimated in xxxx that fibromyalgia patients generated $6,000 per patient per year in healthcare costs, while another recent study of administrative claims found that fibromyalgia healthcare costs can exceed $18,000 per patient per year (Wolfe et al., 1997). In a population-based study of ten chronic diseases, fibromyalgia was ranked first for health care not received in the previous year and for long-term disability, pain, and poor self-rated health by survey participants (Kasman and Badley, 2004). of the most costly chronic diseases in terms of health care utilization costs, in part due to the severity of functional limitations experienced by patients with fibromyalgia. The clinical symptoms of fibromyalgia are complex and are accompanied by sleep disturbances, mood disorders, chronic fatigue, reduced exercise tolerance, and pain exacerbations that severely limit the patient's activities of daily living (Friedberg et al., 2012) . As a result, fibromyalgia patients often engage in sedentary behaviors that reinforce pre-existing physical disabilities and ultimately lead to… middle of paper… 0 minutes, 5-7 days a week. Such small, gradual increases in exercise are unlikely to exacerbate underlying symptoms (Friedberg et al., 2012). Supervised group activities may be preferable to solitary home-based activities as they offer a social support mechanism and encourage continuation of the exercise regime (Rooks, 2007). A review of exercise treatment programs in fibromyalgia patients concluded that the lowest dropout rates occurred in lower-intensity exercise programs rather than high-intensity ones (Hauser et al., 2010). A study by Hauser et al reported that light to moderate intensity aerobic exercise two to three times per week was more effective than other intensity or frequency regimens (Hauser et al., 2010). Improvements in mood, quality of life, and fitness were maintained at follow-up intervals ranging from 3 to 17 months.
