Details and patient eligibility


The purpose of the study is to assess the efficacy and safety of electroacupuncture among women with pelvic organ prolapse(Level II - III), compared with sham electroacupuncture.

Full description

After being informed about the study and potential risk, all patients giving written informed consent form will be undergo a 1-week screening period to determine eligibility for study entry. Eligible patients will be randomly assigned to one of the two groups 1) electroacupuncture group: electroacupuncture will be provided to patients at BL33, BL35 and SP6 for 3 time per week for the first 4 weeks, then twice a week for 4 weeks, and once a week for the last 4 weeks. There will be 24 times of treatment in total in 3 month; 2) sham electroacupuncture group: sham electroacupuncture will be provided to patients at sham acupoints to BL33, BL35 and SP6 with the same schedule as electroacupuncture group.The follow-up time for the two groups are 6 months after treatment. Primary and secondary outcome will be measured at 3, 6, and 9 months from the start of the treatment, respectively.

Interventional model

Parallel Assignment


Triple Blind

160 participants in 2 patient groups

electroacupuncture group
Experimental group
patients will receive electroacupuncture at 3 acupoints(Bladder meridian of foot-taiyang 33 and 35#BL33 and BL35), and Spleen meridian of foot-taiyin 33(SP6)) 3 times/week for 4 weeks, then 3 times/week for 4 weeks, and then once/week for 4 weeks(24 times in total in 3 months), and be followed up for 6 months after treatment. Disposable acupuncture needles with size of 0.30 × 75 mm will be used at BL 33 and BL 35, and needles with size of 0.30 ×40 mm at SP 6. Standardized electroacupuncture apparatuses will be used, and the stimulation will last for 30 minutes with a continuous wave of 20 Hz, and a current intensity of 2 to 6.5 mA at BL33 and BL 35, and 1 to 3.5 mA at SP6.
Other: electroacupuncture
sham electroacupuncture group
Sham Comparator group
patient will receive sham electroacupuncture with the same frequency and amount as applied in the electroacupuncture group, as well as the follow-up period. Disposable acupuncture needles with size of 0.30 × 40 mm will be applied and penetrate the skin of patients for 2 to 3mm at sham acupoints to the 3 acupoints mentioned above. The stimulation will only last for 30-second with a very weak currency intensity and a continuous wave of 20 Hz.
