To investigate pain sensitivity by using quantitative sensory testing in older women with and without cervicogenic headache.
A total of 18 older women (mean age ± standard deviation [SD] 64.28 ± 3.21 years) with cervicogenic headache and 17 healthy controls (65.18 ± 3.89 years) participated in the study. Pain thresholds (pressure, heat, and cold) and suprathreshold heat pain ratings (at 45° C, 47°C, and 49°C) were measured over the temporalis muscle, upper cervical spine, and tibialis anterior muscle. Analysis of variance was used to determine differences in pain outcomes between groups.
Compared to the control group, cold pain threshold in the cervicogenic headache patients was significantly decreased in the upper cervical region (P = .04) but not over the temporalis and tibialis anterior muscles (P > .05). There were no significant between-group differences in pressure pain threshold, heat pain threshold, or suprathreshold heat pain ratings at any sites (P > .05).
Older women with cervicogenic headache have localized pain sensitivity to cold stimuli, suggesting peripheral mechanisms underlie the hyperalgesia.
通过定量感觉测试，研究患有和不患有颈源性头痛的老年女性的疼痛敏感性。
共有 18 名老年女性（平均年龄±标准差[SD]64.28±3.21 岁）患有颈源性头痛，17 名健康对照者（65.18±3.89 岁）参与了这项研究。在颞肌、上颈椎和胫骨前肌上测量疼痛阈值（压力、热和冷）和超阈值热痛评分（在 45°C、47°C 和 49°C 时）。采用方差分析来确定组间疼痛结果的差异。
与对照组相比，颈源性头痛患者的上颈椎区域的冷痛阈值显著降低（P =.04），但颞肌和胫骨前肌上没有显著差异（P >.05）。在任何部位，压力疼痛阈值、热痛阈值或超阈值热痛评分均无显著的组间差异（P >.05）。
患有颈源性头痛的老年女性对冷刺激的疼痛敏感性增加，提示外周机制是痛觉过敏的基础。
