This study is a prospective, randomized controlled trial. The trial is held at Urogynecological Rehabilitation Unit of Physical Medicine and Rehabilitation Department between February 2021 and July 2021. The local ethics committee approve the study (E-60116787-020-4274). All women are informed about the purpose and contents of the study and all women written consent to participate in the study. A random allocation sequence was generated at 1:1 ratio. By using a random number generator, women are randomized into two groups as follows: Group 1 receive BT+IVES (2 times/week), Group 2 receive BT+IVES (5 times/week). All women which are planned to treat during 20 sessions are included in this study. Bladder Training (BT) All women were informed about BT for 30 minutes in two groups. Then it was given as a written brochure to be implemented as a home program. BT, consisting of four stages, did not contain any PFM training programs. At the first stage, all of the women visited the physician who was blinded to the study groups and at the initial visit, the women were familiarized with the location of the PFM and the pelvic anatomy and pathophysiology. After that information session, squeezing the PFM was shown in practice at least once to use in the urgency suppression strategies via digital palpation technique. In the second stage, including urgency suppression strategies, it was aimed to delay urination, to inhibit detrusor contraction and to prevent urgency; by squeezing the PFM several times in a row (women were encouraged to pause/stop their work, sit down if possible, relax the entire body and squeeze PFM repeatedly), breathing deeply, giving their attention to another job for a while and self-motivating (I can do it, I can check the urination, etc.). In the third stage, timed voiding program was started. It was carried out in 2 steps: timed voiding and increasing the time between urination considering the voiding diary. At the last stage, the women were encouraged to continue BT. By increasing their motivation that it is an effective treatment method, compliance to the treatment was increased. Group 1: IVES (2 times in a week) This group included the IVES in addition to all components of the BT. IVES was performed in lithotomy position via electrical stimulation device with a vaginal probe. 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 milliamp (mA). The intensity was controlled according to patients' discomfort level feedback. Group 2: IVES (5 times in a week) This group also included the IVES in addition to all components of the BT as in Group 1. 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.
