Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Background and Aim:

Dyspareunia, or pain during sexual intercourse, is a common component of female sexual dysfunction and may have multifactorial origins, including musculoskeletal and autonomic factors. While pelvic floor rehabilitation is an established treatment approach for musculoskeletal dyspareunia, it may not sufficiently address the autonomic dysregulation commonly observed in chronic pain conditions. The aim of this study is to investigate the effects of adding diaphragmatic breathing exercises and diaphragm manual therapy to standard pelvic floor rehabilitation on pain severity, pelvic floor function, and autonomic nervous system regulation in women diagnosed with musculoskeletal-origin dyspareunia.

Methods:

This randomized controlled clinical trial will be conducted between September 1, 2025, and December 1, 2025, at the Kurbaa Training and Consultation Center in Istanbul. A total of 45 participants aged 18-45 years who meet the inclusion criteria will be randomly assigned into three equal groups (n = 15):

Group I: Pelvic floor rehabilitation only

Group II: Pelvic floor rehabilitation + diaphragmatic breathing exercises

Group III: Pelvic floor rehabilitation + diaphragmatic breathing exercises + diaphragm manual therapy

Interventions will be administered once per week for 8 weeks. Pre- and post-intervention assessments will include pain intensity (Visual Analog Scale), pelvic floor muscle function (ultrasonography), sexual function (Female Sexual Function Index), anxiety level (Beck Anxiety Inventory), and autonomic regulation (Heart Rate Variability using Elite HRV). Statistical analyses will be performed using SPSS with significance set at p \< 0.05.

Expected Contribution:

This study is expected to contribute to the development of more comprehensive treatment protocols for dyspareunia by integrating physical and neurophysiological rehabilitation components. It may also provide evidence supporting the role of autonomic regulation in improving treatment outcomes for female sexual pain disorders.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group I: Pelvic floor rehabilitation

Pelvic floor rehabilitation only

Group Type EXPERIMENTAL

Pelvic floor rehabilitation

Intervention Type OTHER

Participants in this group will receive standard pelvic floor rehabilitation. This includes education about pelvic floor anatomy and function, supervised pelvic floor muscle training (Kegel exercises), relaxation techniques, and manual release of trigger points if necessary. The aim is to improve muscle strength, coordination, and reduce pelvic floor hypertonicity contributing to dyspareunia.

Diaphragmatic Breathing Exercises

Intervention Type OTHER

In addition to the standard pelvic floor rehabilitation, participants in this group will practice diaphragmatic breathing exercises. These exercises focus on deep, slow nasal inhalation using the diaphragm, encouraging abdominal expansion while minimizing chest movement. Sessions are performed twice daily for 10 minutes. This technique is aimed at promoting parasympathetic activation, reducing anxiety, and improving autonomic regulation.

Diaphragm Manual Therapy

Intervention Type OTHER

an additional manual therapy intervention targeting the diaphragm. Diaphragm manual therapy involves hands-on techniques applied to the thoracic and abdominal regions to reduce fascial restrictions, improve diaphragmatic mobility, and support deeper, more effective breathing. The therapy is delivered for 15 minutes at the start of each weekly session by a trained physiotherapist.

Group II: Pelvic floor rehabilitation + diaphragmatic breathing exercises
