Summary

This randomized controlled trial aims to compare the pre- and post-treatment effects of Dynamic Neuromuscular Stabilization (DNS) training and Pelvic Floor Muscle Training (PFMT) on pelvic floor muscle function, pelvic floor morphometry, urinary symptoms, quality of life, sexual function, and physical activity levels in women with stress urinary incontinence (SUI). Participants diagnosed with SUI by a specialist physician will be randomly assigned to one of three groups: DNS, PFMT, or a control group. Both DNS and PFMT interventions will be delivered as 12-week home exercise programs, performed five days a week and at least three times per day. To support adherence, participants will use an exercise diary. In addition, participants in the DNS and PFMT groups will attend the clinic twice a week for supervised sessions led by a physiotherapist. The control group will receive a brochure containing lifestyle and bladder health recommendations but will not engage in any structured exercise program.

Detailed description

Stress urinary incontinence (SUI) is defined by the International Continence Society as involuntary urine leakage due to insufficient urethral closure pressure during episodes of increased intra-abdominal pressure (IAP), such as coughing, sneezing, laughing, or physical activity. The continence mechanism involves intrinsic urethral closure, structural support of the urethra, and lumbopelvic stability. These components are interconnected through the endopelvic fascia and neural pathways. The core musculature-including the diaphragm, transversus abdominis (TrA), pelvic floor muscles, and lumbar multifidus-functions synergistically within the myofascial system to regulate IAP. This coordination is essential for maintaining the optimal function of genitourinary organs, especially the bladder. Dynamic Neuromuscular Stabilization (DNS) targets this integrated spinal stabilization system. DNS exercises are based on developmental kinesiology principles, comparing adult stabilization patterns to those of healthy infants. The goal is to retrain the neuromuscular system through repetitive, functional movements to restore automatic IAP regulation and trunk stability. Although DNS has demonstrated clinical effectiveness in managing musculoskeletal disorders, cerebral palsy, hemiplegia, and athletic injuries, its role in the management of SUI remains underexplored. By promoting synchronous activation of the deep stabilizers-including the diaphragm, TrA, multifidus, and pelvic floor-DNS may offer a more comprehensive therapeutic approach than isolated pelvic floor muscle training. In this context, the main questions of this study it aims to answer are: Does Dynamic Neuromuscular Stabilization (DNS) training have an effect on pelvic floor muscle function, pelvic floor morphometry, symptoms, quality of life, sexual function, and physical activity levels in women with stress urinary incontinence (SUI)? Does Pelvic Floor Muscle Training (PFMT) improve pelvic floor muscle function, pelvic floor morphometry, symptoms, quality of life, sexual function, and physical activity levels in women with stress urinary incontinence (SUI)? Is there a difference between DNS exercises and PFMT in terms of their effects on pelvic floor muscle function, pelvic floor morphometry, symptoms, quality of life, sexual function, and physical activity levels before and after treatment in women with SUI?

Interventions

Type	Name	Description
OTHER	Dynamic Neuromuscular Stabilization Training	According to the principles of Dynamic Neuromuscular Stabilization (DNS), proper activation of the integrated spinal stabilization system requires that the abdominal muscles expand not only in the caudal direction but also posteriorly and laterally.Therefore, firstly, the physiotherapist will assess the expansion of the entire abdominal wall and teach the patient to regulate intra-abdominal pressure through correct breathing techniques. During training and exercises, a belt will be used. Participants will be instructed to maintain abdominal expansion toward the belt during exercises performed in positions supported by proper alignment. A four-phase exercise protocol based on developmental kinesiology principles will be implemented for the DNS group, beginning with supine-position exercises appropriate for the 3-month developmental stage. They will be instructed to repeat the exercises at least three times per day.Patients will record their home exercise program using an exercise diary.
OTHER	Pelvic Floor Muscle Training	Participants in the PFMT group will undergo a structured pelvic floor muscle training program supervised by a physiotherapist. The training will include verbal and manual instructions to ensure correct identification and isolated activation of the pelvic floor muscles without compensatory movements from the gluteal, abdominal, or thigh muscles using a NeuroTrac Simplex EMG-Biofeedback device. The exercise protocol will consist of both slow and fast contractions, focusing on endurance, strength, and coordination. The exercises will be performed in various positions (e.g., supine, sitting, standing) and will gradually progress in intensity and complexity over time, following the principles of motor learning stages. They will be instructed to repeat the exercises at least three times per day. Patients will record their home exercise program using an exercise diary.
