Methods： A total of 20 cases with severe primary dysmenorrhea were randomly allocated into a group of single point. In each treatment, the needles retained for 30 min and 15 person times were observed in each group. The VAS （Visual Analogue Scale） values were recorded immediately before needling, 5 min, 20 min and 30 min upon insertion, and 30 min, 60 min and 120 min upon withdrawal for statistical analysis. Results： Immediate pain relief occurred following acupuncture and the pain-alleviating effect was incremented within the 30 min of needle retaining. At 20 min upon needle insertion, the pain relief from needling multiple points appeared substantially stronger than needling a single point （P〈0.05） and this effect remained until 2 h after withdraw of the needles. Conclusion： Needling a single point or multiple points can both produce remarkably immediate pain relief for patients with severe primary dysmenorrhea and share similar time-effect relationship. However, needling multiple points showed substantially better effects than needling a single point in a number of time points.展开更多
