To evaluate the effectiveness and safety of acupuncture or electroacupuncture in the treatment of women with premenstrual syndrome.
Comparisons between groups intended for treatment with any type of acupuncture and groups allocated to 'sham' acupuncture, no treatment, Chinese medicine, Western medicine or other treatments. The following hypotheses will be tested:
(1) acupuncture is superior to 'sham' acupuncture or no treatment in treating PMS;
(2) acupuncture is superior to other treatments or Western medicine or Chinese medicine in treating PMS;
(3) there are less adverse events in the acupuncture group than in the Chinese medicine or Western medicine groups.
This is a protocol.
