Summary

Electrical stimulation (ES) is one of the techniques used in urogynecological physiotherapy, which uses implanted or non-implanted electrodes. Intravaginal ES (IVES) is a conservative treatment option, described more than 40 years ago. IVES is used in patients with OAB and urge urinary incontinence (UUI), for detrusor inhibition. It has been suggested that IVES probably targets the detrusor muscle or pelvic floor muscle (PFM) or afferent innervation in UUI. According to the European Association Urology (EAU) Guidelines; in adults with urinary incontinence, ES may improve urinary incontinence compared to sham treatment. The IVES programs lasted between 4 weeks and 6 months in women with idiopathic OAB, although generally IVES was applied for 4-12 weeks. In most studies, IVES was applied 2-3 times a week, whereas in fewer studies it was applied more frequently. Despite that, no randomised studies compared different treatment frequencies in women with idiopathic OAB and thus, there is no evidence of which frequencies of treatment are the most effective ones. It should be kept in mind that different stimulation frequency may lead to different results. In addition, in the light of scientific evidence and our clinical experience, we think that this issue is still open for research. Better methodological quality studies are needed to obtain a higher level of scientific evidence and to know the optimal treatment frequency for OAB.

Our study is the first prospective randomized controlled trial that compares the efficacy of IVES with different treatment frequency in women with idiopathic OAB. In this study, we aimed to assess the efficacy of 2 times and 5 times in a week IVES added to BT on quality of life (QoL) and clinical parameters asssociated with idiopathic OAB. The results of the our study will be of great benefit in deciding or preferring the treatment frequency and total treatment duration of IVES for the women with idiopathic OAB and their physicians.

Conditions

Interventions

DEVICE

Intravaginal Electrical Stimulation (2 times/week)

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.

DEVICE

Intravaginal Electrical Stimulation (5 times/week)

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.
