To compare the cumulative analgesic effect of electroacupuncture (EA) stimulation of Sanyinjiao (SP 6), Xuanzhong (GB 39) and non-acupoint for primary dysmenorrhea patients.
A total of 200 patients with primary dysmenorrhea were randomly assigned to Sanyinjiao (SP 6, a dysmenorrheal-relieving related acupoint) group, Xuanzhong (GB 39, an unrelated acupoint) group, non-acupoint group and control group, with 50 cases in each group. The participants were administered with EA (2 Hz/100 Hz, 0.5-1.6 mA) at SP 6, GB 39 and non-acupoint for 30 min, once daily for 3 consecutive days. The intensity of the pain was ranked from 0 (no pain) to 100 (intolerable) using visual analogue scale (VAS) and RSS (Cox retrospective symptom scale) severity rating scores (RSS-COX 2) before and after three interventions.
In comparison with the control group, VAS and RSS-COX 2 scores were significantly lower in the SP 36, GB 39 and non-acupoint groups (P < 0.001, P < 0.05), suggesting an alleviation of the pain severity after EA treatment. No significant differences were found among the three treatment groups in both VAS and RSS-COX 2 scores (P > 0.05).
EA stimulation of SP 6, GB 39 and non-acupoint has a good cumulative analgesic effect in patients with primary dysmenorrhea.
