Effect of Revival Soy on Fibromyalgia Pain
Summary
Fibromyalgia is characterized by widespread pain that can lead to significant patient dysfunction and economic burden to society. The management of patients with fibromyalgia is difficult and no single treatment modality has been successful. We propose to study the effect of dietary soy supplement on quality of life associated with fibromyalgia.
Description
Fibromyalgia syndrome is a chronic, generalized pain syndrome that affects the musculoskeletal system (1). This syndrome is typically diagnosed in patients who experience generalized musculoskeletal pain and have excessive tenderness in at least 11 of 18 specific points (2). Although the primary cause of fibromyalgia syndrome is unclear, a growing body of evidence indicates that the widespread pain associated with this syndrome is due to abnormalities in the central nervous system. Therefore, drug therapy for fibromyalgia syndrome is most often aimed at the central nervous system and includes tricyclic antidepressants, selective serotonin reuptake inhibitors, dual serotonin and norepinephrine reuptake inhibitors, analgesics, and anticonvulsants (1).
In addition to medical therapies, complementary and alternative medicine therapies have been used to treat fibromyalgia syndrome symptoms (3). Soy is a widely used dietary supplement that has not been previously tested for treating fibromyalgia syndrome.

Medical and Biotech [MESH] Definitions
Fibromyalgia
A common nonarticular rheumatic syndrome characterized by myalgia and multiple points of focal muscle tenderness to palpation (trigger points). Muscle pain is typically aggravated by inactivity or exposure to cold. This condition is often associated with general symptoms, such as sleep disturbances, fatigue, stiffness, HEADACHES, and occasionally DEPRESSION. There is significant overlap between fibromyalgia and the chronic fatigue syndrome (FATIGUE SYNDROME, CHRONIC). Fibromyalgia may arise as a primary or secondary disease process. It is most frequent in females aged 20 to 50 years. (From Adams et al., Principles of Neurology, 6th ed, p1494-95)
Therapeutic Misconception
Misunderstanding among individuals, frequently research subjects, of scientific methods such as randomization and placebo controls.
Placebo Effect
An effect usually, but not necessarily, beneficial that is attributable to an expectation that the regimen will have an effect, i.e., the effect is due to the power of suggestion.
Fatigue Syndrome, Chronic
A syndrome characterized by persistent or recurrent fatigue, diffuse musculoskeletal pain, sleep disturbances, and subjective cognitive impairment of 6 months duration or longer. Symptoms are not caused by ongoing exertion; are not relieved by rest; and result in a substantial reduction of previous levels of occupational, educational, social, or personal activities. Minor alterations of immune, neuroendocrine, and autonomic function may be associated with this syndrome. There is also considerable overlap between this condition and FIBROMYALGIA. (From Semin Neurol 1998;18(2):237-42; Ann Intern Med 1994 Dec 15;121(12): 953-9)
