About this study

Official title: Effects of Home-based Telerehabilitation-assisted High-intensity Inspiratory Muscle Training on Pelvic Floor Muscle Function and Urinary Symptoms in Women With Stress Urinary Incontinence: A Randomized Controlled Study

Strengthening the diaphragm muscle, the roof of the pelvic floor muscles (PFM), may be an alternative intervention in patients suffering from stress urinary incontinence (SUI). This study aims to investigate the effects of home-based telerehabilitation-assisted high-intensity inspiratory muscle training (IMT) on PFM function and urinary symptoms in women with SUI.

Read the detailed description

The IMT protocol consisted of home-based high-intensity daily training - two cycles of 30 breaths with a 1-minute rest between sets, twice a day for 8 weeks using an IMT Threshold device (Threshold IMT Philips® Respironics, Inc). The IMT was performed twice a day, 7 days/week, for 8 weeks. The study group performed IMT at 60% of their baseline MIP and was adjusted weekly based on the modified Borg scale from 4 to 6 regarding respiratory effort performed during the session, while the control group performed a sham-IMT without applied resistance. Patients are evaluated before the inspiratory muscle training and after 8 weeks of training.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Inspiratory Muscle Training (IMT)Device

    The IMT protocol will consist of home-based high-intensity daily training - two cycles of 30 breaths with a 1-min rest between sets, twice a day for 8 weeks using an IMT Threshold device (Threshold IMT Philips® Respironics, Inc). The intensity of the training will be set to 60% of each patient's maximal inspiratory pressure measured and adjusted weekly based on the modified Borg scale from 4 to 6 regarding respiratory effort performed during the session. Patients were also informed to perform knack maneuver in daily activities that may cause sudden intra-abdominal pressure overload.

  • Sham IMTDevice

    The IMT protocol will consist of home-based daily training - two cycles of 30 breaths with a 1-min rest between sets, twice a day for 8 weeks using an IMT Threshold device (Threshold IMT Philips® Respironics, Inc). The intensity of the training will be set to the lowest intensity of the IMT Threshold device. Patients were also informed to perform knack maneuver in daily activities that may cause sudden intra-abdominal pressure overload.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change of Pelvic floor muscle functions with Pressure feedbacks

    Pressure feedbacks: Pelvic muscle functions were evaluated with pressure feedback of pelvic muscle using a biofeedback device (Myomed 932®- Enraf-Nonius, Delf, The Netherlands), and recorded in hPa (Hectopascal).

    • Manual muscle test: Manual muscle test was evaluated using the modified Oxford Scale that ranges from 1 to 5. Higher values on this scale indicate better muscle strength.

    Measured: 8 weeks

  2. Change of Pelvic floor muscle functions with Manual muscle test

    The manual muscle test was evaluated using the modified Oxford Scale, which ranges from 1 to 5. Higher values on this scale indicate better muscle strength.

    Measured: 8 weeks

Secondary outcomes (4)
  1. Urogenital Distress Inventory-Short Form

    Urinary symptom was assessed with the Urogenital Distress Inventory-Short Form (range: 0-100) Higher values on this scale indicate worse symptoms.

    Measured: 8 weeks

  2. International Consultation on Incontinence Questionnaire-Short Form

    Urinary incontinence symptom and its effect on the quality of life was assessed with the International Consultation on Incontinence Questionnaire-Short Form (range: 0-21) Higher values on this scale indicate worse symptoms.

    Measured: 8 weeks

  3. Incontinence Severity Index

    Urinary incontinence severity was assessed with the Incontinence Severity Index (range: 1-12). Higher values on this scale indicate worse symptoms.

    Measured: 8 weeks

  4. Inspiratory muscle strength

    The Inspiratory muscle strength was evaluated by maximum inspiratory pressure which was assessed with a digital mouth pressure meter device (MicroRPM, Micro Medical Ltd., Rochester, Kent, United Kingdom), and recorded in cmH2O (centimeter-water).

    Measured: 8 weeks

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change of Pelvic floor muscle functions with Pressure feedbacks (time frame: 8 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06842979, which also lists 12 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Feb 2025; AzTrials last refreshed its copy on 26 Oct 2026.
