Brief summary

Urinary incontinence (UI) is defined as the involuntary loss of urine that occurs outside the individual's control and negatively affects both hygiene and social life. Research indicates that individuals with UI experience decreased core muscle strength and endurance, which may also lead to changes in balance parameters. Therefore, the aim of this study was to investigate core muscle strength, endurance, and balance parameters in women with UI, taking the type of UI into consideration. This study was conducted between January 2025 and April 2025 at the Urogynecology Clinic of Başakşehir Çam and Sakura City Hospital in Istanbul, with patients diagnosed with UI by a specialist physician. A total of 32 participants were included. All participants were administered a demographic assessment form; the International Physical Activity Questionnaire-Short Form (IPAQ-SF) to assess physical activity level; the Pelvic Floor Distress Inventory (PFDI-20) and all of its subscales to evaluate the severity of symptoms associated with pelvic floor distress; urodynamic measurement; a pad test to assess the severity of UI; a perineometer device to evaluate pelvic floor muscle (PFM) strength; the Sahrmann five-level core stabilization test and the Stabilizer Pressure Biofeedback Unit to assess core muscle strength; McGill's Trunk Endurance Tests for core endurance; and the Y Balance Test to assess balance.

Primary

MeasureTime frameDescription
Assessment of Pelvic Floor Muscle StrengthAt the day of enrollmenta previously validated perineometer with good inter-rater reliability and reproducibility was used to assess pelvic floor muscle strength. a previously validated perineometer with good inter-rater reliability and reproducibility was used to assess pelvic floor muscle strength. A previously validated perineometer with good inter-rater reliability and reproducibility was used to assess pelvic floor muscle strength.
Assessment of Urine Flow Rate and VolumeAt the day of enrollmentA uroflowmetry device was used to assess urine flow rate and volume. A uroflowmetry device was used to assess urine flow rate and volume
Assessment of Urinary Incontinence SeverityAt the day of enrollmentA 1-hour pad test was used to determine the severity of urinary incontinence.
Assessment of Core Muscle StrengthAt the day of enrollmentThe Stabilizer Pressure Biofeedback Unit® (Chattanooga Medical Supply Inc., Chattanooga, TN) was used to determine the level of core stabilization.
Assessment of Core Endurance and StabilityAt the day of enrollmentThe test protocol developed by McGill and colleagues was applied to measure core endurance.
Balance AssessmentAt the day of enrollmentThe Y Balance Test was used to assess balance.

Secondary

MeasureTime frameDescription
International Physical Activity Questionnaire - Short Form (IPAQ-SF)At the day of enrollmentThe IPAQ-SF is a brief self-report questionnaire used to assess the physical activity levels of individuals over the past 7 days. It measures the frequency and duration of walking, moderate-intensity, and vigorous-intensity activities.
Pelvic Floor Distress Inventory-20 (PFDI-20)At the day of enrollmentThe PFDI-20 is a questionnaire designed to evaluate the presence and severity of pelvic floor distress symptoms, including urinary, colorectal, and pelvic organ prolapse symptoms. It helps assess the impact of these symptoms on a patient's quality of life.
