Intravaginal Electrical Stimulation With Different Treatment Frequency in Women With Idiopathic Overactive Bladder

IVES sessions were performed two times in a week, for 10 weeks. Every session lasted 20 minutes. The intervention comprised a 20-sessions treatment program of ES. The stimulation parameters were frequency at 10 Hz, a 5-10s work-rest cycle and 100 ms pulse width. The symmetric biphasic pulse wave could be delivered over a range of 0-100 mA. The intensity was controlled according to patients' discomfort level feedback.

IVES performed in the same way as Group 1, except for frequency of treatment. IVES sessions were performed five times in a week, for 4 weeks. Every session lasted 20 minutes. The intervention comprised a 20-sessions treatment program of ES. Stimulation parameters were the same as Group 1.
