To evaluate the effect of wet needling (related to acupuncture) and home stretching exercises on myofascial trigger points (MTrPs) in abdominal muscles for the treatment of dysmenorrhoea.
The effect of wet needing of MTrPs in abdominal muscles, supplemented by home stretching exercises, was observed in 65 patients with moderate and severe primary dysmenorrhoea. The MTrPs in the abdominal region were localised and repeatedly needled with lidocaine injection. Menstrual pain was evaluated with a Visual Analogue Scale (VAS) score after every treatment, with the final evaluation made at a 1-year follow-up. Treatment was stopped when the VAS pain score reduced to ≤3. Symptoms scores were analysed with one-way analysis of variance.
The mean VAS pain score before treatment was 7.49±1.16. After a single wet needling session, 41 patients had a reduction in their VAS pain score to <3 during their following menstrual cycle, with a mean of 1.63±0.49. Twenty-four patients who needed two treatments showed a reduction in menstrual pain scores to 0.58±0.50. After 1 year, the mean VAS pain score among all patients was 0.28±0.45, with a response rate of 100%.
Primary dysmenorrhoea was significantly reduced 1 year after wet needling to MTrPs in the abdominal region and home stretching exercises, justifying further research with controlled trials.
评估与针灸相关的湿针疗法及家庭伸展运动对腹部肌肉肌筋膜触发点（MTrP）治疗痛经的效果。
观察65例中重度原发性痛经患者，对腹部肌肉的MTrP进行湿针治疗，并辅以家庭伸展运动。对腹部区域的MTrP进行定位，并用利多卡因注射反复针刺。每次治疗后用视觉模拟评分法（VAS）评估痛经情况，在1年随访时进行最终评估。当VAS疼痛评分降至≤3分时停止治疗。症状评分采用单因素方差分析。
治疗前VAS疼痛评分均值为7.49±1.16。单次湿针治疗后，41例患者在下一个月经周期VAS疼痛评分降至<3分，均值为1.63±0.49。24例需要两次治疗的患者痛经评分降至0.58±0.50。1年后，所有患者的VAS疼痛评分均值为0.28±0.45，有效率为100%。
腹部区域MTrP的湿针疗法及家庭伸展运动1年后原发性痛经明显减轻，有必要通过对照试验进行进一步研究。
