Fibromyalgia and chronic fatigue syndrome are poorly understood disorders that share similar demographic and clinical characteristics. Because of the clinical similarities between both disorders it was suggested that they share a common pathophysiological mechanism, namely, central nervous system dysfunction. This chapter presents data demonstrating neurohormonal abnormalities, abnormal pain processing and autonomic nervous system dysfunction in fibromyalgia and chronic fatigue syndrome. The possible contribution of the central nervous system dysfunction to the development and symptomatology of these conditions is discussed. The chapter concludes by reviewing the effect of current treatments and emerging therapeutic modalities in fibromyalgia and chronic fatigue syndrome.

Chronic widespread musculoskeletal pain has been subjected to several epidemiological studies during the last decade. According to these, approximately 10% of the general population report such complaints, clearly indicating chronic widespread musculoskeletal pain as a major health problem in the Western world. Almost unanimously, all studies found higher rates of such complaints among women compared with men, but the mechanisms responsible for the skewed gender ratio remain unknown.Chronic widespread musculoskeletal pain is the clinical hallmark of fibromyalgia and has been the subject of numerous epidemiological studies. The prevalence of fibromyalgia is reportedly 3-5%, again with a significant female predominance. Although the aetiopathogenesis of both fibromyalgia and chronic widespread musculoskeletal pain without other features of fibromyalgia remains an enigma, there is a body of evidence suggesting psychological and sociocultural factors as important for contracting such pain syndromes.

This chapter reviews our current knowledge on the presence of overlapping syndromes in one form of chronic diffuse pain, fibromyalgia. Patients with fibromyalgia often present with signs and symptoms of other unexplained clinical conditions, including chronic fatigue syndrome, irritable bowel syndrome, temporomandibular disorders, and multiple chemical sensitivities. The high prevalence, impact on function and opportunities for treatment underscore the need for clinicians and researchers to screen routinely for co-morbid unexplained clinical conditions among persons with fibromyalgia. We, therefore, describe a simple approach to screening for such conditions in accordance with published criteria. Interventions should directly address both fibromyalgia symptoms and co-morbid unexplained clinical conditions, as well as the multiple factors that propagate pain, fatigue and limitations in function.

Fibromyalgia is defined by widespread pain and tenderness at a minimum of 11 of 18 defined tender points. Current evidence indicates that tender points are not unique to fibromyalgia and are simply regions in the body where all people are more tender. Tenderness (i.e. sensitivity to pressure) is widespread in fibromyalgia rather than being confined to tender points, and patients are also more sensitive to heat, cold and electrical stimulation. Using the number of painful tender points as a measure of tenderness is clinically expedient but is theoretically vulnerable to bias and is influenced by subjective distress. Other means of assessing tenderness (e.g. pressure dolorimeter devices, or more elaborate psychophysical methods) demonstrate the same increased pain sensitivity in fibromyalgia that is noted with tender point assessments, but these measures are relatively independent of biasing factors or distress. Fibromyalgia is one of only a few syndromes defined by the presence of both spontaneous (i.e. clinical) and evoked (i.e. experimental) pain. While the issues associated with the evaluation of spontaneous pain are shared with all chronic pain syndromes, the issues associated with the evaluation of evoked pain sensitivity are specific to fibromyalgia and related musculoskeletal disorders. This chapter focuses on the evaluation of altered pain sensitivity in fibromyalgia. It describes current measurement methodology, briefly reviews studies of sensitivity to experimentally evoked painful and non-painful sensations, analyses the factors assessed by different measurement methodologies, and concludes with recommendations for future diagnostic criteria and measurement methods.

The fibromyalgia syndrome (FMS) is a common, chronic, widespread pain disorder that mainly affects middle-aged women. In addition to pain complaints, fatigue and disturbed sleep are symptoms frequently reported by these patients. Many FMS patients also meet diagnostic criteria for mood disorders (e.g. depression) as well as other so-called 'functional somatic syndromes', including irritable bowel syndrome, temporomandibular joint disorder, and subsets of chronic low-back pain. A wide variety of medications are used to manage the eclectic symptomatology of FMS patients, although relatively few have been rigorously tested. This chapter provides a contemporary update of the state of FMS pharmacotherapy, with an emphasis on compounds that have been tested in double-blind, randomized, controlled trials. Particular attention is paid to the efficacy of these therapies on the associated symptoms and co-morbid syndromes commonly seen in FMS patients.

Fibromyalgia and related syndromes are characterized by chronic pain and fatigue. This chapter identifies the types of exercise that are effective for these patients and provides recommendations for exercise prescriptions. Based on a systematic review of randomized controlled studies of exercise, we suggest that low-intensity aerobic exercise, such as walking, can improve function and symptoms. Aerobic exercise performed twice a week at moderate intensity can improve aerobic capacity and reduce tenderness. Pool exercise can improve function, distress and symptoms. Strength training at adequate load can improve strength without exacerbation of symptoms. Most patients tolerate low-intensity exercise. High-intensity exercise should be undertaken with caution. Due to the large variability of functioning and symptom severity in patient populations, exercise prescriptions should be individualized and should include a long-term plan to maximize functioning and wellbeing. Studies with larger populations, allowing subgroup analyses regarding benefits and adverse effects of programmes, are needed.

Psychological and behavioural therapies are being applied to patients with fibromyalgia (FM) with increasing frequency. The rationale for including psychological therapies is not for the treatment of co-morbid mood disorders, but rather to manage the many non-psychiatric psychological and social factors that comprise pain perception and its maintenance. This chapter reviews the involvement of mental health professionals under both the biomedical and biopsychosocial models of illness and describes cognitive behavioural therapy (CBT), a commonly used form of psychological therapy in the management of chronic pain conditions. The empirical literature supports the use of CBT with FM in producing modest outcomes across multiple domains, including pain, fatigue, physical functioning and mood. Greatest benefits appear to occur when CBT is used adjunctively with exercise. While the benefits are not curative or universally obtained by all patients, the benefits are sufficiently large to encourage future refinement of CBT for this population of patients.

Complementary and alternative medicine (CAM) has gained increasing popularity, particularly among individuals with fibromyalgia syndrome (FMS) for which traditional medicine has generally been ineffective. A systematic review of randomized controlled trials (RCTs) and non-RCTs on CAM studies for FMS was conducted to evaluate the empirical evidence for their effectiveness. Few RCTs achieved high scores on the CONSORT, a standardized evaluation of the quality of methodology reporting. Acupuncture, some herbal and nutritional supplements (magnesium, SAMe) and massage therapy have the best evidence for effectiveness with FMS. Other CAM therapies have either been evaluated in only one RCT with positive results (Chlorella, biofeedback, relaxation), in multiple RCTs with mixed results (magnet therapies), or have positive results from studies with methodological flaws (homeopathy, botanical oils, balneotherapy, anthocyanidins, dietary modifications). Lastly, other CAM therapies have neither well-designed studies nor positive results and are not currently recommended for FMS treatment (chiropractic care).

Fibromyalgia (FM) is currently defined as the presence of both chronic widespread pain (CWP) and the finding of 11/18 tender points on examination. Only about 20% of individuals in the population with CWP also have 11/18 tender points; these individuals are considerably more likely to be female, and have higher levels of psychological distress. There is no clear clinical diagnosis for the other 80% of individuals with less than 11/18 tender points, but it is likely that these persons, like FM patients, also have pain that is 'central' (i.e. not due to inflammation or damage of structures) rather than peripheral in nature. Research into FM has taught us a great deal about the confluence of neurobiological, psychological and behavioural factors that can cause chronic central pain. These conditions respond best to a combination of symptom-based pharmacological therapies, and non-pharmacological therapies such as exercise and cognitive behavioural therapy. In contrast to drugs that work for peripheral pain due to damage or inflammation (e.g. NSAIDs, corticosteroids), neuroactive compounds [especially those that raise central levels of noradrenaline (norepinephrine) or serotonin] are most effective for treating central pain.

Rheumatologists frequently encounter patients whose illnesses lack face-value; that is, they lack the typical objective features of pathology that rheumatologists traditionally rely on for diagnosis and developing effective treatment approaches: namely fibromyalgia, chronic fatigue syndrome, Gulf War syndrome, chronic whiplash, chronic low back pain, etc. In this article, we examine this group of illnesses as culture-driven disorders to emphasize the central importance of various societal constraints in the ultimate presentation of patients with these illnesses. We will examine them by first understanding the purpose they serve, the underlying factors that compel societal institutions to sanctify these disorders as diseases, and how research is beginning to examine the behaviour that captures and packages these symptoms to produce their clinical presentation. With this research understanding, rheumatologists may be able to offer patients more useful action plans, but likely changes in societal approaches to the expressions of distress and changes in disability and compensation systems will also be required.
