目的: 观察下关穴氦氖激光穴位照射模拟针刺治疗慢性每日头痛的有效性和比较该疗法与红光照射作为安慰剂对照之间存在的差异性。方法: 以氦氖激光穴位照射模拟针刺和红光照射作为安慰剂对照进行比较, 选取下关穴治疗慢性每日头痛, 开展随机、对照、双盲的临床研究。采用头痛日记与中医证候疗效评分判定疗效。结果: 受试者在激光照射组治疗4周后与治疗前比较, 在发作次数、疼痛程度方面均有显著改善(P＜0.05), 与红光照射组同期相应指标比较均存在统计学差异(P＜0.05)。受试者治疗后中医症候疗效评分均呈不同下降, 主症评分相当, 次症评分激光照射组优于红光对照组, 存在统计学差异性(P＜0.05)。结论: 与红光照射作为安慰剂对照相比, 下关穴氦氖激光穴位照射模拟针刺治疗慢性每日头痛确有一定疗效。

Object: To observe the therapeutic effects of the He-Ne laser acupoint-irradiation at Xiaguan (ST 7) to the chronic daily headache, compared with the efficacy of infrared light as the placebo. Method: Randomized controlled double-blind clinical trial was conducted on patients with chronic daily headache by giving experimental group the He-Ne laser acupoint-irradiation at Xiaguan (ST 7), while giving the control group infrared light. The headache diary and the score of syndrome differentiation were adopted as the criterion for therapeutic evaluation. Result: The headache diary, VAS and attack scores, of the laser irradiation group improves significantly at the 4th weeks(P＜0.05), compared with the control group at the same period with significance(P＜0.05). Furthermore, the score of syndrome differentiation also improved in both group. The major symptoms is no significance, while the minor symptoms is significance in favor of the experimental group with the irradiation of the He-Ne laser on acupoints(P＜0.05).Conclusion: He-Ne laser irradiation at acupoint Xiaguan (ST 7) has a significant therapeutic efficacy on patients with chronic daily headache,compared with the infrared light as the placebo.
