“…Strength training for FM and chronic pain is well-supported. (28, 37, 45, 60-62) Recent studies have demonstrated more robustly that strength training is both safe and effective for a variety of chronic pain conditions. (61, 62) Land-based training appears to yield greater strength gains than aquatic resistance training.…”

Chronic pain broadly encompasses both objectively defined conditions and idiopathic conditions that lack physical findings. Despite variance in origin or pathogenesis, these conditions are similarly characterized by chronic pain, poor physical function, mobility limitations, depression, anxiety and sleep disturbance and are treated alone or in combination by pharmacologic and nonpharmacologic approaches, such as physical activity (aerobic conditioning, muscle strengthening, flexibility training and movement therapies). Physical activity improves general health, disease risk and progression of chronic illnesses such as cardiovascular disease, type-2 diabetes and obesity. When applied to chronic pain conditions within appropriate parameters (frequency, duration, intensity), physical activity significantly improves pain and related symptoms. For chronic pain, strict guidelines for physical activity are lacking, but frequent movement is preferable to sedentary behavior. This gives considerable freedom in prescribing physical activity treatments, which are most successful when tailored individually, progressed slowly and account for physical limitations, psychosocial needs and available resources.

Objective: To compare the heart rate variability (HRV) before and after a sub-maximal exercise test in women with fibromyalgia (FM) and to compare the result to matched controls. Additionally, to compare heart rate (HR) before, during and after the sub-maximal exercise test.Methods: Twenty-four women with FM and 26 controls performed a sub-maximal exercise test. HRV was registered for 5 minutes at rest before and after the exercise test. HR was registered at baseline, during the exercise test and at recovery. Results:The HRV of the healthy group was statistically different from the exercise test but the women with FM showed no such difference. HR was significantly higher among the women with FM than in the healthy group at baseline and up to 75W but lower at peak (138/152 bpm, p<0.008). In women with FM HR during exercise (HR2) was predicted by heart rate recovery (HRR20) and physical exertion (RPE2). HRR20 and RPE2 accounted for 0.465 of the variance (p=0.006) in HR2. In healthy women HR2 correlated with HRR20 and negatively with physical activity (PhA). In the reference group HRR20 and PhA accounted for 0.448 (p=0.002) of the variance HR. Conclusion:The HRV in women with FM show less adjustment of the ANS while not being significantly affected by submaximal exercise as healthy women. In healthy women heart rate during the test was negatively related to PhA. In women with FM exertion seems to replace an effect from exercise on physiological adaptation. FM may entail imperceptible extraction of power from PhA while under load. Links to FM pain will be discussed.Women with FM seem to rate exertion "Very hard" on lower workload and HR than healthy women. The physiotherapeutic methodology for measuring HRV with basic HR monitors should be improved before it can be recommended for clinical use.

“…21 The intensity of the 12 different strengthening exercises was set at 45% of the estimated load of 1 repetition maximum. Strengthening exercises were more effective for strength gain in all muscles and pain control after 4 and 16 weeks, while flexibility exercises resulted in greater reductions in anxiety.…”

Fibromyalgia (FM) is a challenge to clinicians and patients because of its constellation of symptoms that are frequently shared with other chronic pain conditions, and the lack of a definitive diagnostic test or known cause. This article reviews the epidemiology, diagnostic issues and criteria, conventional and complementary and alternative medicine (CAM) therapies used to treat FM, the evidence base for CAM therapies, and theories of the causes of this complex disorder that affects the health-related quality of life (HRQoL) of millions of patients. Historical Background and EpidemiologyDerived from the Latin term for fibrous tissue (fibro) plus the Greek terms for muscle (myo) and pain (algia), FM is a disorder of unknown etiology characterized by chronic widespread pain and fatigue. 1 Symptoms may also include sleep disturbances, morning stiffness, cognitive problems, and depression. Although FM is often considered a rheumatic condition like arthritis, FM does not cause inflammation of-or damage to-the joints, muscles, or other tissues. The syndrome was called "fibrositis" prior to the mid-1970s. 2 The first controlled clinical study validating the symptoms of FM was published in 1981. The idea that FM was interconnected with similar conditions was also proposed in the 1980s. The American College of Rheumatology (ACR) published its first diagnostic criteria for FM in 1990, which were later revised.Recent estimates put the prevalence of FM in the United States as ranging from 2% to 8% of the population, second only to osteoarthritis (OA) as the most common "rheumatic" disorder. 3 The prevalence is similar in many other countries. The majority of patients affected are women, although FM can also affect men and children. Diagnostic Issues and CriteriaThere is currently no diagnostic test specifically for FM. In addition, many patients experience symptoms that also characterize other chronic pain disorders, including chronic fatigue syndrome, irritable bowel syndrome (IBS), temporomandibular disorders, and migraine. American College of Rheumatology CriteriaThe ACR developed criteria for classifying FM in 1990; this classification focused on tenderness upon pressure in at least 11 of 18 tender-point sites, in conjunction with widespread pain-defined as pain in 3 of the 4 quadrants of the body. No distinction was found between the diagnoses of primary and secondary FM, so the use of these terms was abandoned. 4 The ACR criteria accelerated research on FM, but were revised in 2010 in response to issues raised regarding the necessity of a tender-point-examination, lack of consideration of nonpain symptoms, and the observation that FM might represent the extreme end of a pain spectrum. 5 Daniel J. Clauw, MD-a professor of anesthesiology, medicine (rheumatology), and psychiatry at the University of Michigan in Ann Arbor, and director of the university's Chronic Pain and Fatigue Research Center-is among researchers who questioned the clinical utility of the ACR's emphasis on tender points in diagnosing FM. 6 Dr. Clauw com...
