A new definition of Fibromyalgia syndrome (FMS) based on symptoms and without tender points is discussed from a rheumatological viewpoint.
Methods: The German Fibromyalgia Association (DFV) developed a questionnaire on potential symptoms in FM based on a list of symptoms established by members of the DFV. The questionnaire was sent to all 3,996 members of the DFV.
Results: Of the 753 questionnaires 699 were returned (95% women, most frequent age between 50-60 years) and evaluated. The rank order of the most frequent symptoms (>/=97% of the respondents) was:
- muscle pain with varying locations,
- low back pain,
- morning stiffness,
- non-restorative sleep,
- concentration problems,
- lack of energy,
- low productivity
- and forgetfulness.
Conclusion: The key symptoms of FM are: Chronic widespread pain, non-restorative sleep and subjective disabilities.
