Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
