Fibromyalgia (FM): clinical trials and information

Fibromyalgia is a long-term condition described by widespread body pain, often with fatigue, sleep problems and difficulty with memory or concentration. Its causes are not fully understood; research has looked at how the nervous system processes pain signals, and at genetics, infections, physical or emotional trauma and stress as possible contributing factors. It is diagnosed more often in women than in men.

There is no single laboratory test for fibromyalgia. Clinicians usually base a diagnosis on a person's history of widespread pain and other symptoms over several months, a physical examination, and tests to rule out other conditions with similar symptoms.

Registered studies cover medicines, medical devices (such as nerve stimulators), procedures (such as nerve blocks or injections), physical and movement therapies, psychological approaches (such as cognitive behavioural therapy), education programs and digital tools. Being studied in a trial does not mean a treatment works or is approved. The interventions listed on this page come directly from the registry records.
