This meta-analysis aimed to evaluate the effectiveness of acupuncture or acupressure at the Sanyinjiao (SP6) acupoint in relieving pain associated with primary dysmenorrhea. We searched the scientific literature databases to identify randomized controlled trials. The primary outcome was visual analogue scale (VAS) pain score. Three acupuncture and four acupressure trials were included in the meta-analyses. For the acupuncture analysis, there was no difference in the mean VAS score reduction between the SP6 acupoint and control (GB39 acupoint) groups (-4.935; lower limit = -15.757, upper limit = 5.887; P = 0.371). For the acupressure analysis, there was a significant difference in the mean VAS score after intervention between the SP6 acupoint and control (rest/light touch at SP6/nonacupoint acupressure) groups, favoring the SP6 acupoint group (-1.011; lower limit = -1.622, upper limit = -0.400; P = 0.001). Sensitivity analyses demonstrated good reliability of the meta-analyses findings. These findings suggest that acupuncture at SP6 is not more effective than acupuncture at an unrelated acupoint in the relief from primary dysmenorrhea. Acupressure at SP6 may be effective in the relief from primary dysmenorrhea. High-quality randomized controlled trials are needed to confirm these findings.
本荟萃分析旨在评估三阴交（SP6）穴位针刺或按压缓解原发性痛经相关疼痛的有效性。我们检索了科学文献数据库以识别随机对照试验。主要结局指标是视觉模拟评分（VAS）疼痛评分。荟萃分析纳入了 3 项针刺试验和 4 项按压试验。对于针刺分析，SP6 穴位组与对照组（GB39 穴位）的平均 VAS 评分降低无差异（-4.935；下限=-15.757，上限=5.887；P=0.371）。对于按压分析，干预后 SP6 穴位组与对照组（SP6 穴位休息/轻触/非穴位按压）的平均 VAS 评分有显著差异，SP6 穴位组更优（-1.011；下限=-1.622，上限=-0.400；P=0.001）。敏感性分析表明荟萃分析结果具有良好的可靠性。这些发现表明，与无关穴位针刺相比，SP6 穴位针刺在缓解原发性痛经方面效果不更优。SP6 穴位按压可能在缓解原发性痛经方面有效。需要高质量的随机对照试验来证实这些发现。
