Twenty-six patients were examined during attacks of common migraine as well as during headache-free interval. Pericranial tenderness was scored blindly by a systematic manual palpation on both occasions by the same observer. Pressure-pain threshold (PPT) in a fixed location over the temporal muscle was determined by the use of a pressure algometer. A 28% increase in total tenderness score was observed during attacks (P less than 0.01). During unilateral attacks, tenderness scores were significantly higher on the ipsilateral side as compared to the contralateral (P less than 0.01). A positive correlation was observed between tenderness on the two sides (P less than 0.05) and the two occasions (P less than 0.01). PPT showed no changes during migraine attacks and there was no difference in PPT between the ipsilateral and contralateral side. A positive correlation was observed between PPT on the two sides and the two occasions (P less than 0.01). PPT was not correlated to the tenderness scores obtained by manual palpation. The absence of a decrease in PPT and the presence of several tender areas in multiple regions, particularly where pain was spontaneously reported to be located, suggest the presence of either a multi-focal peripheral pathological process or referred pain from other structures in the head and neck region.
对26名患者在普通偏头痛发作期间以及无头痛间歇期进行了检查。在这两种情况下，由同一名观察者通过系统的手动触诊对颅周压痛进行盲法评分。使用压力痛觉计测定颞肌上固定位置的压痛阈（PPT）。在发作期间观察到总压痛评分增加了28%（P<0.01）。在单侧发作期间，患侧的压痛评分明显高于对侧（P<0.01）。两侧压痛之间（P<0.05）以及两次检查之间（P<0.01）均观察到正相关。偏头痛发作期间PPT无变化，患侧和对侧的PPT无差异。两侧PPT之间以及两次检查之间均观察到正相关（P<0.01）。PPT与手动触诊获得的压痛评分无关。PPT没有降低，且在多个区域存在多个压痛部位，特别是在自发报告疼痛所在的部位，这表明存在多灶性外周病理过程或头颈部其他结构的牵涉痛。
