Comparison of Two Different Pelvic Floor Muscle Training Programs in Stress Urinary Incontinence

Study Overview
=================
Brief Summary
-----------------
Pelvic floor muscle training (PFMT) is indicated as a first-line treatment for stress urinary incontinence. PFMT aims to improve pelvic floor muscle strength, endurance and relaxation ability or a combination of these. PFMT is a structured and customized exercise program. Pelvic floor muscles work in synchronization with many muscles and pelvic floor muscle function is supported by synergistic muscles. Relationships between the functions of pelvic floor muscles and synergistic muscle groups have been reported in the literature. However, studies comparing the efficacy of PFMT and combined training of these muscles are limited and more studies are needed. Therefore the aim of this study is to compare the effects of isolated PFMT and functional PFMT in women with stress urinary incontinence.

Detailed Description
-----------------
Our study is designed as a parallel group, randomized clinical trial. Participants who meet the inclusion criteria will be assigned randomly to one of the study groups. The participants in the 1st group will be given classical PFMT, and the participants in the 2nd group will be given functional PFMT. The study period is 8 weeks for each individual participating in the study. All participants will be called for control every 2 weeks and progress will be made in exercise programs in accordance with the protocol. At the beginning of the study, demographic information, physical characteristics, smoking habit, primary and secondary urinary symptoms and their duration, obstetric history, menstrual and menopausal status, comorbidities, drugs used and, if any, the effects of these drugs on the urinary system, previous UI treatments and their duration will be recorded. For individuals over 65 years of age, Mini Mental Test will be applied in terms of cooperation suitability for the research. The objective severity of incontinence will be assessed with the 1-hour pad test. The subjective severity of incontinence and its impact on life will be evaluated with the International Incontinence Consultation Questionnaire-Short Form (ICIQ-UI SF). The King's Health Questionnaire (KHQ) will be used to investigate the effects of interventions on the sub-dimensions of quality of life. With the Patient Global Impression of Severity Scale and the Patient Global Impression of Change Scale, the individual's perception of severity and recovery of UI will be evaluated. Vaginal palpation will be performed to determine whether individuals can voluntarily contract their pelvic floor muscles and to teach correct contraction before pelvic floor muscle training. Outcome measurements will be recorded at the beginning of the study, at the end of the 4th week and at the end of the 8th week. Participants will be given an exercise diary to increase motivation and exercise adherence.

Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Classical Pelvic Floor Muscle Training<br>In the first 2 weeks of classical pelvic floor muscle training, individuals will perform 3 sets of 10 maximal voluntary pelvic floor muscle contraction exercises and 20 submaximal voluntary pelvic floor muscle contraction exercises per day. In every 2-week control, the number of sets will be increased by one set. | Other: Classical Pelvic Floor Muscle Training<br>* In the first 2 weeks of classical pelvic floor muscle training, individuals will perform 3 sets of 10 maximal voluntary pelvic floor muscle contraction exercises and 20 submaximal voluntary pelvic floor muscle contraction exercises per day. In every 2-week control, the number of sets will be increased by one set.<br>|
| Experimental: Functional Pelvic Floor Muscle Training<br>Functional pelvic floor muscle training will be started with 3 exercises (toe tap, bridge and clamshall exercises), each exercise will be performed with 1 set and 30 repetitions. In every 2-week control, the number of exercises will be increased by one. Cat-cow exercise will be added at 3-4th weeks, squats will be added at 5-6th weeks, and lunges will be added at 7-8th weeks. | Other: Functional Pelvic Floor Muscle Training<br>* Functional pelvic floor muscle training will be started with 3 exercises (toe tap, bridge and clamshall exercises), each exercise will be performed with 1 set and 30 repetitions. In every 2-week control, the number of exercises will be increased by one. Cat-cow exercise will be added at 3-4th weeks, squats will be added at 5-6th weeks, and lunges will be added at 7-8th weeks.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Symptom Severity and Impact of Incontinence on Life by International Urinary Incontinence Consultation Questionnaire Short Form | International Urinary Incontinence Consultation Questionnaire Short Form will be used to evaluate the change in symptom severity and impact of incontinence on life. Score ranges are 1-5 (slight), 6- 2 (moderate), 13-18 (severe) and 19-21 (very severe). Lower scores mean a better outcome for this questionnaire form. | Change in International Urinary Incontinence Consultation Questionnaire Short Form score from baseline to end of 8th week | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Incontinence Severity by 1-hour pad test | 1-hour pad test will be used to evaluate the incontinence severity. There is no minimum and maximum values. Lower scores mean a better outcome. | Change in incontinence severity from baseline to end of 8th week. | 
| The Impact of Incontinence on Quality of Life by King Health Questionnaire | King Health Questionnaire will be used to evaluate the effect of incontinence on quality of life. Minimum value is 0 and maximum value is 130. Lower scores mean a better outcome. | Change in King Health Questionnaire score from baseline to end of 8th week. | 
| Participant's Perception of Symptom Severity by Patient Global Impression of Severity Scale | Patient Global Impression of Severity Scale will be used to evaluate the participant's perception of symptom severity. Score ranges are 1 to 4. Lower scores mean a better outcome. | Change in Patient Global Impression of Severity Scale score from baseline to end of 8th week. | 
| Participant's Perception of Recovery by Patient Global Impression of Change Scale | Patient Global Impression of Change Scale will be used to evaluate the participant's perception of recovery.
