Study summary

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.

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Interventions

  • OtherPelvic floor rehabilitation

    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.

  • OtherDiaphragmatic Breathing Exercises

    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.

  • OtherDiaphragm Manual Therapy

    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.

What researchers measure

Primary outcomes

  1. Pelvic Floor Muscle Function Measured by Ultrasonography (mm displacement)

    Change in displacement of pelvic floor muscle during contraction, measured via transabdominal ultrasonography. Higher values indicate stronger muscle activity.

    Time frame: Baseline and Week 8

  2. Female Sexual Function Index (FSFI) Total Score

    FSFI is a validated 19-item questionnaire (Score range: 2-36), with higher scores indicating better sexual function.

    Time frame: Baseline and Week 8

  3. Heart Rate Variability (HRV) Index Measured with Elite HRV

    Time-domain and frequency-domain HRV parameters. Higher HRV indicates better autonomic balance.

    Time frame: Baseline and Week 8

Secondary outcomes

  1. Pain Intensity During Intercourse Assessed by VAS (0-10 cm)

    VAS line score from 0 (no pain) to 10 (worst imaginable pain). Higher scores indicate worse pain.

    Time frame: Baseline and Week 8

  2. Beck Anxiety Inventory (BAI) Total Score

    BAI includes 21 items scored 0-3 each (Total Score: 0-63); higher scores indicate worse anxiety.

    Time frame: Baseline and Week 8

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Sep 2025; primary completion for Jul 2026, 10 months later.

Of 51 non-industry interventional studies with no phase under Dyspareunia, half reached primary completion within 33 months of starting (the median), counting those still running; a quarter within 14 and three quarters within 48. This study's planned 10 months is below that.

Counting every sponsor, half of 59 studies reached it within 33 months; a quarter within 13 and three quarters within 38.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 22, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
