- Brief Summary
Multiple sclerosis (MS) is the most common inflammatory disease of the central nervous system. It is characterized with demyelinated plaques affecting subcortical, brain stem, and spinal cord nerve fibers. During the course of the disease, with the affection myelinated nerve tracks, lower urinary track symptoms may occur. 50-90% of the MS patients experience lower urinary track symptoms (LUTS) such as urinary incontinence, urgency, nocturia and/or urinary frequency during the at one point of their life.
Aim of this study is to determine the effects of transcutaneous tibial nerve stimulation (TTNS) on symptoms and quality of life in MS patients with LUTS.
- Detailed Description
This is a single-centered, prospective, single blind, randomized controlled study of patients with MS who suffer lower urinary track symptoms. All patients will be informed of the details of all the procedures and of the details of the study. After the written informed consent is obtained, patients will be distributed to two equal groups using randomized number table.
At the beginning and end of the study, post-void residue (PVR) will be calculated with ultrasonography, International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF), Incontinence Quality of Life( I-QOL), 3 day bladder diary (number of urination, urge, incontinence, nocturia) forms will be administered.
Patients will be evaluated via PVR, urodynamic measurements, ICIQ-SF, I-QOL and bladder diary.

Group Intervention Description Pelvic floor exercises and Transcutaneous tibial nerve stimulation Pelvic floor exercises Patients in this group will receive pelvic floor exercise program as described before and transcutaneous tibial nerve stimulation (TTNS). The intervention will comprise 12 session of transcutaneous tibial nerve stimulation (Twice a week, for 6 continuous weeks). Each session will last 30 minutes. Two self adhesive surface electrodes will be positioned according to the protocol used by Booth et al and Sonmez et al, with the negative electrode 2 cm behind the medial malleolus, and positive electrode 10 cm proximal to it. Correct positioning will be determined by noting a hallux reaction (plantar flexion of great toe). Stimulation will be delivered at fixed frequency of 20 Hz and pulse width of 200 ms. The intensity level of the stimulation current (range 0-50 mA) will be determined once hallux reaction is observed, according to patient's tolerance. Pelvic floor exercises and Sham Stimulation Sham stimulation Patients in this group will receive pelvic floor exercise program as described before and Sham stimulation. The intervention will comprise 12 session of sham stimulation. (Twice a week, for 6 continuous weeks) Each session will last 30 minutes. Two self adhesive surface electrodes will be positioned According to the protocol used by Booth et al, with the negative electrode 2 cm behind the lateral malleolus, and positive electrode 10 cm proximal to it, therefore avoiding the posterior tibial nerve. The stimulation current will be reduced to 2 mA once the tingling sensation is obtained and patients will be informed that they may not feel electrical sensation during the session. Stimulation will be delivered at fixed frequency of 20 Hz and pulse width of 200 ms. If willing, patients in this group will receive TTNS treatment after the study is completed.

- Primary Outcome Measures
Name Time Method Incontinence Quality of Life (I-QOL) 6 weeks (Before and after the treatment) I-QOL is used for evaluation of quality of life in patients with incontinence. It comprises 22 questions presented under three subscales: limiting behavior, psychosocial impact, and social embarrassment. All the questions are based on a five-point Likert scale (1 = a lot, 2 = quite a bit, 3 = moderate, 4 = a little, and 5 = not at all). Points obtained by each question are added together which results in a total point of 0 to 110. This total point is then recalculated to take a value between 0-100 for better understand. Higher scores indicate a better quality of life. Validation of turkish version is available.
- Secondary Outcome Measures
Name Time Method Bladder diary 6 weeks (Before and after the treatment) 2 or 3 day bladder diary is recommended by European Association of Urology in patients with lower urinary track symptoms. Urination frequency, urgency, incontinence and nocturia will be evaluated using 3 day bladder diary.
Post-void residue (PVR) 6 weeks (Before and after the treatment) Post-void residue (PVR) will be calculated with ultrasonography. Evaluation will be made by same person in all patients after urination, in supine position transabdominally with 2-5 Mhz convex probe using E-Saote Mylab Seven (Italy) device.
International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF) 6 weeks (Before and after the treatment) ICIQ-SF allows the assessment of incontinence's severity, frequency and its impact on quality of life. ICIQ-SF scoring is also a practical and reliable method for baseline and post-treatment evaluation of patients with urge incontinence. It contains six questions. First and second questions are about demographics and the sixth question is about conditions that lead to incontinence. First, second and sixth questions have no point value. Total score varies between 0 and 21 and is obtained by adding third, fourth and fifth question's points. Higher scores indicate greater problems with incontinence. Validation of turkish version is available.
