Fibromyalgia, chronic fatigue syndrome, and myofascial pain syndrome

Abstract

Operational diagnostic criteria for fibromyalgia were applied to most clinical studies during the past year. Similar diagnostic criteria for chronic fatigue syndrome are being revised, but criteria for myofascial pain have not been agreed on or tested. Intense research efforts focused on the role of neurohormones and the hypothalamic-pituitary-adrenal axis in fibromyalgia and chronic fatigue syndrome over the past year.
