About this study
Official title: Ultrasound Assessment of Rectus Abdominis Muscle Thickness and Residual Bladder Volume Before and After Pelvic Floor Exercises
The study will be conducted on 40 women between the ages of 20-40 who volunteer to participate in the study. All participants will be selected from individuals who have been diagnosed with pelvic floor dysfunction and have no history of pelvic surgery. Pelvic floor dysfunction will be diagnosed by an Obstetrics and Gynecology Specialist. Participants will be divided into two groups as the Pelvic floor exercise group and the control group.
Read the detailed description
The study will be conducted on 40 women between the ages of 20-40 who volunteer to participate in the study. All participants will be selected from individuals who have been diagnosed with pelvic floor dysfunction and have no history of pelvic surgery. Pelvic floor dysfunction will be diagnosed by an Obstetrics and Gynecology Specialist. Participants will be divided into two groups as the Pelvic floor exercise group and the control group. Group distributions will be made by randomization.org website. Participants in the pelvic floor exercise group will be instructed to do daily pelvic floor exercises under the guidance of a physiotherapist specialized in pelvic health. No exercises will be given to women diagnosed with pelvic floor dysfunction in this group. Women will continue their routine lives and their evaluations will be made.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Pelvic floor exercisesOther
The bladder should be emptied before the exercise. In order to correctly identify the pelvic floor muscles, it is necessary to initially try to hold urine while emptying the bladder. If the result is successful, it means that the correct muscles have contracted. During the learning phase, the exercise can be done in a supine position with the legs bent at the knees or in a sitting position. Initially, the pelvic floor muscles should be contracted for 5 seconds by pulling them inward as if stopping the passage of urine or gas, and then rested for 5 seconds.
Control groupOther
Women in this group who have been diagnosed with pelvic floor dysfunction will not be given any exercises. Women will continue their routine lives and their evaluations will be made.
| Study group | Role | What they receive |
|---|---|---|
| Pelvic floor exercise group | Experimental | Participants will be instructed to perform daily pelvic floor exercises under the guidance of a physical therapist specializing in pelvic health. The exercises focus on isolated pelvic muscle contractions and core muscle engagement. The exercises will be performed 3 times per day for 6 weeks. Receives: Other: Pelvic floor exercises |
| Control Group | Other | Women in this group who have been diagnosed with pelvic floor dysfunction will not be given any exercises. Women will continue their routine lives and their evaluations will be made. Receives: Other: Control group |
What is being measured
The primary outcome is the main question the study is designed to answer.
Ultrasound Measurements
Ultrasound measurements will be performed at two points: at baseline (before the exercise program) and after 6 weeks of intervention. A high-resolution ultrasound device will be used to measure the thickness and cross-sectional area of the rectus abdominis muscle at rest.
Measured: 20 minutes
The residual bladder volume measurement
The residual bladder volume immediately after voiding will also be measured by ultrasonography to assess bladder control.A normal post-void residual volume is between 50 mL (milliliters) and 100 mL.
Measured: 20 minutes
