不同针刺时间治疗原发性痛经的临床研究（英文）

Clinical studies on different acupuncture time for primary dysmenorrhea

目的:寻求针刺治疗原发性痛经的最佳针刺时间,为优化针刺治疗原发性痛经方案提供更好的临床依据。方法:将90例符合纳入标准的患者随机分为3组,每组30例。3组均针刺关元及双侧足三里和三阴交,A组治疗15 min,B组治疗30 min,C组治疗45 min。根据治疗后疼痛症状积分的变化评价临床疗效。结果:组内比较,3组治疗前后疼痛症状积分均有统计学差异(均P<0.05);组间比较,治疗后B组疼痛症状积分明显低于A组和C组,组间差异有统计学意义(均P<0.05)。3组临床疗效有统计学差异(均P<0.05)。结果提示30 min的针刺时间治疗痛经的疗效最佳。结论:在针刺手法相同的条件下,30 min的治疗时间对原发性痛经的临床疗效较好。

Objective： To seek the optimal acupuncture time for primary dysmenorrhea and provide clinical basis for optimal acupuncture treatment protocol. Methods： A total of 90 eligible cases were randomly allocated into three groups, 30 cases in each group. Points Guanyuan（CV 4）, bilateral Zusanli（ST 36） and Sanyinjiao（SP 6） were selected for patients in all three groups, with a different treatment duration： 15 min in group A, 30 min in group B and 45 min in group C. Then the clinical efficacy in each group was evaluated by pain symptom scoring. Results： As for the pain symptom scores, there were statistically significant intra-group differences between before and after treatment in three groups（all P〈0.05）; coupled with statistically significant inter-group differences between group B and the other two groups（both P〈0.05）. As for clinical efficacy, there were statistical differences between group B and the other two groups（both P〈0.05）, indicating that 30 min of acupuncture is the optimal duration in the treatment of dysmenorrhea. Conclusion： With the same needling manipulation, 30 min of acupuncture treatment achieves a better efficacy for primary dysmenorrhea.
