Clinical trial to evaluate efficacy and safety of Electroacupuncture and Acupuncture in Postmenopausal Women with overactive bladder

INTERVENTION: Medical Device : For the EA and AC groups, disposable, sterilized, filiform needles (diameter 0.25 mm, length 40 mm; Dong‐Bang Acupuncture Inc., Seoul, Korea) will be inserted into the skin at the following acupoints: unilaterally at CV3, CV4, and GV20, bilaterally at KI3 and SP6. When inserting at CV3, the needling direction will be toward CV2. The needles will be inserted to a depth of between 5 and 30 mm, and the acupuncture needles will be manipulated to achieve de qi and retained for 20 min. In the EA group, electrical stimulation will be performed simultaneously during the retaining period. An electric acupuncture device (CellMac STN‐330, Stratek Co., Republic of Korea) will be connected to the CV3‐CV4 and KI3‐SP6 acupoints and deliver stimulation with a 2 Hz or 16Hz frequency, a maximum intensity below the threshold. Electrical stimulation will be delivered at an intensity that the participant can notice but will still feel comfortable with.
