To compare the effectiveness of trigger point dry needling (TrP-DN) versus placebo needling, relative to an untreated control group, on pain and quality of life in primary dysmenorrhoea.
In this randomised, single blind, parallel-group trial, 56 females with primary dysmenorrhoea were randomly allocated to TrP-DN (n=19), placebo needling (n=18) or no treatment (n=19). Patients in both groups were asked to undertake a stretching exercise of the rectus abdominis daily. The needling group received a single session of TrP-DN to trigger points (TrPs) in the rectus abdominis, and the placebo group received placebo needling. The primary outcome was pain intensity (visual analogue scale). Secondary outcomes were quality of life, use of non-steroidal anti-inflammatory drugs, the number of days with pain, and self-perceived improvement, measured using a Global Rate of Change. Outcomes were assessed at baseline, and 1 and 2 months after the treatment.
Females receiving TrP-DN exhibited greater decreases (P<0.001) in pain than those receiving placebo (1 month: Δ-19.8 mm, 25.9 to -13.7; 2 months: Δ-26.0 mm, -33.1 to -18.9) or assigned to the untreated control group (1 month: Δ-26.0mm, -32.5 to -19.5; 2 months: Δ-20.1 mm, -26.4 to -13.8). Females in the TrP-DN group also exhibited a greater decrease in the amount of medications (P<0.001). No differences in the number of days with pain or quality of life were found (all P>0.1).
This trial suggests that a single session of TrP-DN of the rectus abdominis combined with stretching was more effective than placebo needling and stretching alone at reducing pain and the amount of medication used in primary dysmenorrhoea.

比较触发点干针（TrP-DN）与安慰剂针刺相对于未治疗对照组在原发性痛经中的疼痛和生活质量的疗效。
在这项随机、单盲、平行组试验中，56 名原发性痛经女性被随机分配到 TrP-DN（n=19）、安慰剂针刺（n=18）或无治疗组（n=19）。两组患者均被要求每天进行腹部直肌伸展运动。针刺组接受腹部直肌触发点（TrP）单次 TrP-DN 治疗，安慰剂组接受安慰剂针刺。主要结局是疼痛强度（视觉模拟评分）。次要结局是生活质量、非甾体抗炎药的使用、疼痛天数和自我感知改善，使用整体变化率进行评估。在基线、治疗后 1 个月和 2 个月进行评估。
接受 TrP-DN 治疗的女性疼痛减轻程度大于接受安慰剂治疗（1 个月：Δ-19.8mm，25.9 至-13.7；2 个月：Δ-26.0mm，-33.1 至-18.9）或未治疗对照组（1 个月：Δ-26.0mm，-32.5 至-19.5；2 个月：Δ-20.1mm，-26.4 至-13.8）。TrP-DN 组女性的药物使用量也减少更多（P<0.001）。疼痛天数或生活质量无差异（均 P>0.1）。
本试验表明，腹部直肌单次 TrP-DN 联合伸展运动比安慰剂针刺和单独伸展运动更能有效减轻原发性痛经的疼痛和药物使用量。
