PAIN PERCEPTION AND HEALTH CARE SEEKING BEHAVIOR IN FIBROMYALGIA

这项调查已进入第二个五年周期的第四年。 本研究的主要目的是检查3组患者和健康对照组在（a）静息条件下和（B）5分钟暴露于疼痛机械压力刺激期间疼痛敏感性和脑局部脑血流量（rCBF）的实验室测量值之间的差异。3个患者组由右利手女性组成，她们患有（a）纤维肌痛，（B）慢性疲劳综合征，和（3）重度抑郁症。 对患者进行仔细筛选，以消除各组之间这些诊断的重叠。迄今为止，我们主要研究了纤维肌痛患者和健康对照。 然而，我们现在有了新的慢性疲劳综合症和重度抑郁症患者转诊来源。 因此，我们预期在2001年12月前完成所有主题研究。

This investigation is in the 4th year of its second 5-year cycle. The primary aim of the present study is to examine differences between 3 groups of patients and healthy controls on laboratory measures of pain sensitivity and in brain regional cerebral blood flow (rCBF) during (a) resting conditions and (b) a 5-minute exposure to painful mechanical pressure stimulation. The 3 patient groups consist of right-handed women with (a) fibromyalgia, (b) chronic fatigue syndromes, and (3) major depression. Patients are carefully screened to eliminate overlap in these diagnoses across groups. We primarily have studied patients with fibromyalgia and health controls, to date. However, we now have new referral sources for patients with chronic fatigue syndrome and major depression. Thus, we anticipate completing all subject studies by December, 2001.
