title: Fibrositis/fibromyalgia: a form of myofascial trigger points?
abstract: The diagnostic criteria for fibrositis and primary fibromyalgia are similar to those for myofascial pain syndromes due to trigger points. Tender points in muscles are likely to be myofascial trigger points; nonmuscular tender points clearly are not myofascial trigger points, but may be areas of tenderness referred from such trigger points. Myofascial trigger points refer pain to a distance and restrict range of motion of the muscle. They are associated with a palpable taut band that exhibits a local twitch response of the muscle, and they are responsive to treatment. Persistence of myofascial trigger points is due to perpetuating factors that can usually be corrected. Although their number is unknown, it is likely that some patients who are diagnosed as having fibrositis/fibromyalgia have multiple myofascial trigger points aggravated by a powerful perpetuating factor and also have a systemic disease process independent of the myofascial trigger points. Since myofascial pain syndromes are treatable, these patients would benefit greatly by identification and relief of the myofascial component of their pain.
