目的：这项研究的目的是调查中国一所大学医院神经内科门诊中心原发性刺伤性头痛（PSH）的临床特征及其患病率。
方法：我们通过医生使用头痛问卷的面对面访谈对患者进行了调查。
结果：在1,219名参与的头痛患者中，18例（1.5%）被诊断为PSH。平均年龄为44.1±15.5岁。61.1％的患者头痛局限于单个固定区域。据报道，额叶大脑区域是最常见的区域。14例患者（77.8％）患有中度至重度头痛，平均11分疼痛评分为4.3±1.9。在患者中，27.8％的患者伴有畏光/畏音的症状是最常见的主诉。50%的患者报告了触发因素，天气变化是一个常见的触发因素。
结论：PSH被证明在中年时发病，中度至重度强度发作主要位于三叉神经的第一分支内。伴随现象和触发因素是常见的，应该注意，暗示要进行进一步的研究。
OBJECTIVE: The aim of this study was to investigate the clinical characteristics of primary stabbing headache (PSH) and its prevalence in a neurology outpatient center at a university hospital in China.
METHODS: We surveyed patients via face-to-face interviews by physicians using a questionnaire for headache.
RESULTS: Of 1,219 participating patients with headache, 18 (1.5%) were diagnosed with PSH. The mean age was 44.1 ± 15.5 years. The headaches were localized to a single fixed area in 61.1% of patients. The frontal cerebral regions were reported as most common areas. Fourteen patients (77.8%) suffered from moderate to severe intensity headache with a mean score of 4.3 ± 1.9 on an 11-point pain scale. Of the patients, 27.8% had accompanying symptoms with photophobia/phonophobia as the most common complaint(s). Fifty percent of patients reported trigger factors, with weather change noted as a common trigger.
CONCLUSIONS: PSH was shown to have an onset at middle age with moderate-to-severe intensity attacks localized predominantly within the first division of the trigeminal nerve. Accompanying phenomena and trigger factors were common and should be noted, implying further research to be conducted.
