Pelvic Floor Contraction in Different Positions Among Women With and Without Stress Urinary Incontinence

Study Overview
=================
Brief Summary
-----------------
Examination of pelvic floor contraction in different positions among women with and without stress urinary incontinence (SUI) will be conducted via diagnostic ultrasound. This will enable clinicians and researchers to establish an appropriate protocol for pelvic floor muscle examination and treatment.

Detailed Description
-----------------
The main goal of this study is to compare the ability of the pelvic floor muscles to contract in different positions among women suffering from SUI to healthy women. Secondary objectives: is to compare subjective reports of the difficulty to contract the pelvic floor muscles between the two groups, and to examine the connection between the severity of urinary leakage and the ability to contract pelvic floor muscles. The study will include 50 female participants in the ages of 18-45. Research group will include 25 participants suffering from SUI in accordance with the International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF) and 25 healthy participants (grade 0 on the ICIQ-SF questionnaire). The examination will be performed with an abdominal ultrasound device in supine, sitting, standing and squatting. The Height of the bladder base will be measured during rest period and maximal contraction. The extent and direction of bladder base movement would indicate the quality of pelvic floor performance. Next, the length of contraction time will be measured. The participant would hold the maximal contraction as long as possible in order to examine muscular endurance. Rest will be given between tests. After finishing the tests in all four postures, the participants will be questioned about the degree of difficulty contracting the pelvic floor. Significance of the study: The importance of the research is about granting the clinicians and researchers additional tools in order to help establishing a protocol for pelvic floor muscle activity examination and treatment.

Eligibility Criteria
-----------------
Inclusion Criteria (general): willing to participate in the study being able to squat for over 10 seconds. inclusion for study group - participants suffering from SUI that received a grade>0 in sections 3+4 (how frequent does urinary leakage appear, the amount of urine leakage and does the participant use pads for leakage absorption) and a grade>0 in section 5 (how much does SUI interrupt the participant's daily life) in the International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF). Inclusion for control group - healthy participants (grade 0 in the ICIQ- SF questionnaire).

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| direction of urinary bladder displacement during contraction | upward or downward displacement of urinary bladder will be measured via diagnostic ultrasound | baseline | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| urinary bladder displacement in millimeters | bladder displacement will be measured via diagnostic ultrasound using the on screen caliper tool | baseline | 
| pelvic floor muscles endurance of contraction in seconds | time of muscle contraction will be measured during the last contraction | baseline | 
| questioned about the degree of difficulty contracting the pelvic floor. | Each participant will grade on a scale of 1-10 (10 most difficult) the subjective difficulty of contraction in each position | baseline |
