Abstract

Changes of the second suppressive period (ES2) of the exteroceptive suppression of the temporalis muscle activity are found in patients with chronic tension-type headache (TTH) and are suggested to reflect an abnormal endogenous pain control system. We investigated whether similar changes are found in patients with the fibromyalgia syndrome (FMS) that is also believed to result from disturbed central pain processing. The ES2 values of 27 patients with FMS were compared with those of 18 patients with TTH and 40 healthy volunteers. The duration of ES2 (±SD) in FMS patients was 30.6±7.5 ms and was not significantly different from the control group (33.1±7.8 ms), whereas it was significantly shortened in TTH patients (22.9±11.5 ms). Our results indicate that, despite similar concepts on the pathophysiology of the two chronic pain disorders, there are no comparable changes of this brain stem reflex activity in FMS.

纤维肌痛、紧张性头痛和正常对照患者颞肌活动的外感受性抑制

慢性紧张性头痛(TTH)患者颞肌活动外感受性抑制的第二抑制期(ES2)发生变化，可能反映了内源性疼痛控制系统的异常。我们调查了纤维肌痛综合征(FMS)患者是否也发现了类似的变化，FMS也被认为是中枢性疼痛处理紊乱的结果。将27例FMS患者的ES2值与18例TTH患者和40名健康志愿者的ES2值进行比较。FMS患者ES2(±SD)持续时间为30.6±7.5 ms，与对照组(33.1±7.8 ms)无显著差异，而TTH患者ES2持续时间明显缩短(22.9±11.5 ms)。我们的研究结果表明，尽管两种慢性疼痛疾病的病理生理学概念相似，但FMS中脑干反射活动没有可比较的变化。
