Abstract:

Objective: To conduct a pilot trial to explore the effectiveness and safety of moxibustion robots in treating primary dysmenorrhea (PD) and evaluate its feasibility in clinic. Methods: A total of 70 participants with PD were allocated to either moxibustion robot (MR) group (35 cases) or manual moxibustion (MM) group (35 cases) using computer-generated randomization. One acupoint Guanyuan (CV 4) was selected to receive moxa heat stimulation. Two groups of participants were given 3 menstrual cycles of MM and MR treatment respectively (once a day, 5 days a session) and received another 3 menstrual cycles follow-up. The degree of pain was evaluated by short-form McGill pain questionnaire (SF-MPQ) and the symptoms of dysmenorrhea were evaluated by Cox Menstrual Symptom Scale (CMSS). The safety was measured by the occurrence rate of adverse events (AEs), including burns (blisters, red and swollen), itching, bowel changes, menstrual cycle disorder, menorrhagia and fatigue, etc. Results: A total of 62 patients completed the trial, 32 in MR group and 30 in MM group. Compared with baseline, scores of SF-MPQ and CMSS significantly decreased in both groups (P<0.05), and no significant difference was observed between the two groups in the 3rd and 6th menstrual cycles (P>0.05). The total occurrence rate of AEs in MR group was 2.1%, which was significantly lower than MM group (7.2%, P<0.05). Conclusion: MR has the same effect as MM at SF-MPQ and CMSS in patients with PD. However, MR is safer than MM (Trial registration No. ChiCTR1800018236).
