- Brief Summary
Urinary symptoms are frequently seen in patients with Multiple Sclerosis (MS). Early evaluation of the patients in terms of the urinary system, planning the appropriate treatment and following up at regular intervals are extremely important in terms of preventing urinary system complications. Neuromodulation applications are used reliably in the urological treatment of MS patients. The aim of this study was to compare the efficacy of different neuromodulation techniques, transcutaneous posterior tibial nerve stimulation and repetitive transcranial magnetic stimulation, in patients with MS reporting lower urinary tract symptoms.
- Detailed Description
Bladder dysfunction is one of the most disturbing symptoms of MS. The frequency of bladder dysfunction in patients with MS is reported to be %52-97. Urinary symptoms are among the initial symptoms in %10-15 of patients, while it is the only initial symptom in up to %2 of patients. Patients is seen with irritative symptoms (such as frequent urination, urgency, urinary incontinence, nocturia), obstructive symptoms (such as difficulty in initiating urination, inability to urinate, feeling of incomplete emptying, weak urine flow) or mixed type symptoms.In line with these symptoms, early evaluation of MS patients in terms of urinary system, planning of appropriate treatment and regular follow-up are extremely important in terms of preventing urinary system complications. Pharmacotherapy and clean intermittent catheterization are the first step treatments for lower urinary tract symptoms in multiple sclerosis. It has been reported in the literature that electrical nerve stimulation therapy (neuromodulation methods) and behavior change methods (pelvic floor muscle exercise, bladder training, urinary diary keeping) are also used as a second step treatment option due to the side effects of anticholinergic use and lack of motivation and skill in catheterization. It is reported that neuromodulation applications are performed in MS patients and it is a reliable method. Deep brain stimulation, transcranial magnetic stimulation, posterior tibial nerve stimulation, sacral neuromodulation and spinal cord stimulation are generally recommended in the treatment of bladder dysfunction, which is one of the neuromodulation methods. The superiority of these methods to each other is debatable. In line with this information, the aim of the study is to compare the effectiveness of different neuromodulation techniques, transcutaneous posterior tibial nerve stimulation and repetitive transcranial magnetic stimulation, in MS patients reporting lower urinary tract symptoms.
According to the treatment protocols of the patients to be included in the study; will be divided into 2 groups as transcutaneous posterior tibial nerve stimulation group (8 patients) and repetitive transcranial magnetic stimulation group (8 patients). Which method will be applied to which individual will be determined randomly. Treatment sessions will be carried out for 5 consecutive days in 2 consecutive weeks, 1 time per day for a total of 10 sessions. The urological parameters of the patients in all groups will be evaluated before and after the treatment.
Statistical method(s); Statistical analysis of the data obtained from the study will be done in the Statistical Package for the Social Sciences (SPSS) 22.0 package program. The mean standard deviation, median, minimum and maximum values will be used to define the data. Comparison of continuous variables between groups will be done with Mann Whitney U test, comparison of discrete variables will be done with chi-square test. Spearman or Pearson correlation test will be used to evaluate the correlation between variables. In the data analysis, p \< 0.05 level will be considered statistically significant.

- Primary Outcome Measures
Name Time Method Extended Disability Status Scale (EDSS) "10 days" the amount of change after 10 days from the baseline It is the most commonly used scale to assess disability in MS. EDSS scoring is based on the neurological examination results of eight functional systems and the patient's ambulation status. Functional systems are listed as pyramidal, cerebellar, brainstem, sensory, bladder and intestinal, visual, cerebral, and others. A score of 0-10 is given.0 denotes normal neurological examination, 10 denotes death due to MS. 1.0-4.5 refers to fully ambulatory, 5.0-9.5 refers to impaired ambulation. From 7.0 onwards there is wheelchair use and increasingly bed dependency.
Incontinence Quality of Life -I-QOL "10 days" the amount of change after 10 days from the baseline It consists of a total of 22 questions with three sub-dimensions. Sub-dimensions; limitation of behaviors (1,2,3,4,10,11,13,20 items), psychosocial influence (5,6,7,9,15,16,17,21,22 items) and social isolation (8,12 ,14,18,19 items). All items are evaluated with a five-point Likert type (1= too much, 2= a quite, 3= moderately, 4= a little, 5= not at all) and the Likert types are recalculated to take a value between 0-100 points in order to better understand the total score calculated. Higher scores indicate better quality of life.
Incontinence Severity Index (ISI) "10 days" the amount of change after 10 days from the baseline It consists of 2 questions, and the total score is obtained by multiplying the frequency of urinary incontinence and the amount of urine leaked, and the score range varies between 1-12. According to their score, 1-2 points are light; 3-6 points average; 8-9 points indicate severe and 12 points very severe urinary incontinence.
Voiding Diary "10 days" the amount of change after 10 days from the baseline It is recommended to present the information given by the patients in an objective way. Although not entirely diagnostic, diary data can reveal normal and abnormal conditions. The 3-day voiding diary is a viable, reliable and valid tool in the evaluation of patients with lower urinary tract symptoms.
Urodynamics Test "10 days" the amount of change after 10 days from the baseline While the bladder is being filled, it will be carried out to measure the pressures in the bladder and in the abdomen, to examine the nerves that provide bladder contractions, and to explain the cases of urinary incontinence or inability by examining the bladder contraction pressures and electrical activity during urination.
Overactive Bladder Questionnaire-V8 (OAB-V8) "10 days" the amount of change after 10 days from the baseline The severity of the patients' complaints, none (0); very few (1); a little (2); quite a few (3); many (4); and too many (5) it consists of 8 questions that can be graded. The total score can vary between 0 and 40.
