Wet Needling of Myofascial Trigger Points in Abdominal Muscles for Treatment of Primary Dysmenorrhoea

Abstract

Objectives

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.

Methods

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.

Results

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%.

Conclusions

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.
