Summary

Overactive bladder (OAB) syndrome is urinary urgency, usually accompanied by frequency and nocturia, with or without urgency urinary incontinence, in the absence of urinary tract infection. For the treatment of OAB; pharmacological and non-pharmacological methods are available. The availability and the continuation rate of pharmacological treatments are lower than non-pharmacological treatments due to side effects.

Non-pharmacologic treatment methods are evaluated in two groups as active and passive methods. Active methods which active participation of the patient is required during treatment are Pelvic floor muscle exercise (PFME), biofeedback assisted PFME, vaginal cones, while passive methods are Electrical Stimulation, extracorporeal Magnetic Stimulation (MStim) and Transcutaneous Tibial Nerve Stimulation (TTNS) techniques.

In this study, investigators aim to evaluate the effectiveness of TTNS and extracorporeal MStim, which are noninvasive methods, added to bladder training (BT) in women with OAB, with a prospective randomized controlled research method.

Description

This study is a prospectively randomized, controlled trial. The trial will be held at Urogynecological Rehabilitation Unit of Pamukkale University, Physical Medicine and Rehabilitation Department between Nisan 2022 and October 2022. The local ethics committee approved the study (approvel no: 60116787-020/59365).

Participants will be informed about the purpose and contents of the study and all women give written consent to participate. By using a random number generator, all participants who include the study will be randomized into three groups as follows: The Group 1 will receive BT program alone, the Group 2 will be applied to BT plus TTNS, The Group 3 was applied to BT plus MStim.

Group 1: BT - Control group:

All women will be informed about BT for 30 minutes. Then it will be given as a written brochure to be implemented as a home program.

BT, consisting of four stages, will not contain any PFMT programs in anyone of three groups.

Group 2: BT plus TTNS:

Two self-adhesive surface electrodes will be positioned according to the protocol previously used with the negative electrode 2 cm behind the medial malleolus and positive electrode 10 cm proximal. Correct positioning will be determined by noting a hallux reaction (plantar flexion of great toe or fanning of all toes). The stimulation protocol will be delivered at fixed 20 Hz and pulse width 200 ms in continous mode in accordance with the PTNS stimulation protocol. The intensity of the stimulation current (range 0-50 mA) will be determined once correct positioning was established, according to the comfort level of the person. TTNS sessions will be performed twice a week for 6 weeks. Every session will be lasted 30 min. Treatment will consist of 12 sessions of stimulation.

Group 3: BT plus MStim:

Pariticipants will be told to sit on the chair with a magnetic coil below the chair. When a volume conductor is in serted by this magnetic field, an eddy current flow is generated. This eddy current stimulates nerve or muscle of the pelvic floor. To apply MStim, the device will be set to generate its maximum stimuli, with a stimulation pulse width of 200 μs and a stimulation repetition cycle of 10 Hz in accordance with the literature (10,13-15). When setting the device at each treatment session, participants will be interviewed so that they'll receive stimuli at the maximum stimulation intensity (maximum tolerable stimulation intensity). MStim will be applied two days a week, 20 minutes a day, a total of 12 sessions for 6 weeks. MStim sessions will be performed by other physician.
