Brief Summary
Based on the pain threshold and visual simulation score, primary dysmenorrhea patients will be divided into treatment effective group or non-effective group.According to the functional magnetic resonance imaging, the investigators investigate whether there is characteristic or secondary brain features before and after rTMS intervention.

Outcome Measures
Primary Outcomes (1)
Evaluation of effect of rTMS for primary dysmenorrhea
Assessments using Visual Analog Score for pain(Units on a Scale) in primary dysmenorrhea during menstrual phase to evaluate the effect of rTMS
From 1 month before treatment to 3 months after treatment for each volunteers(through study completion, an average of 2 years)
Study Arms (2)
active rTMS
ACTIVE COMPARATORsham rTMS
SHAM COMPARATORInterventions
(rTMS) is received preliminary approval because of its noninvasive and safe analgesic effect.
Eligibility Criteria
You may qualify if:
- consistent with the diagnostic criteria for primary dysmenorrhea according to the American College of Obstetricians and Gynecologists;
- regular menstrual cycles (27-32 days);
- the average intensity of dysmenorrhoeic pain in the past 6 months should be rated ≥4 on a visual analogue scale (VAS) (0 = no pain, 10 = the worst imaginable pain).
You may not qualify if:
- organic pelvic disease;
- using oral contraceptives, hormonal supplements, Chinese traditional medicine or any central-acting medication (e.g., opioids, anti-epileptics) within 6 months before the study;
- comorbid chronic pain states;
- alcohol, nicotine or drug addiction;
- neurologic disease or psychiatric disorder;
- history of childbirth;
- a positive pregnancy test or immediate plans for pregnancy;
- any MRI contraindications. In addition, no analgesics were consumed 24 hours prior to the experiment.
