Temporal muscle blood flow was measured with the xenon 133 clearance technique in 40 patients with chronic tension-type headache and in 13 control subjects. Pressure-pain threshold in the temporal region was determined with an algometer. Patients and control subjects did not differ in any of the blood flow parameters. Resting blood flow at the two sides was highly correlated (Spearman coefficient, r = .61) and no right/left differences could be demonstrated. In both patients and control subjects, blood flow increased approximately fivefold during isometric work (1/3 of a maximum surface electromyogram). Reactive hyperperfusion after isometric work was found in 8 patients and in 1 control subject. There was no definite correlation between the pressure-pain threshold and the corresponding blood flow. It is not likely that temporal muscle ischemia is the cause of muscle tenderness and pain in patients with chronic tension-type headache.
采用氙133清除技术测量了40例慢性紧张型头痛患者和13例对照者的颞肌血流量。用痛觉计测定颞部的压痛阈。患者和对照者的任何血流参数均无差异。两侧的静息血流量高度相关（斯皮尔曼系数，r = 0.61），未发现左右差异。在患者和对照者中，等长运动（最大表面肌电图的1/3）期间血流量增加约五倍。8例患者和1例对照者在等长运动后出现反应性充血。压痛阈与相应血流量之间无明确相关性。慢性紧张型头痛患者的肌肉压痛和疼痛不太可能是由颞肌缺血引起的。
