Brief Summary

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.

Pelvic Floor Disorders

pelvic floor exercises; rectus abdominis muscle thickness; residual bladder

Outcome Measures

Primary Outcomes (2)

• 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.

  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.

  20 minutes

Study Arms (2)

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.

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.

Other: Control group

Interventions

Pelvic floor exercises OTHER

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 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.
