About this study
Official title: Effectiveness of Ultrasonography Visual Biofeedback for Diaphragm Training in Athletes With Non-specific Lumbo-pelvic Pain
Objective: To determine the effectiveness of diaphragm visual biofeedback reeducation by ultrasonography in conjunction with high-intensity inspiratory muscle training versus isolated high-intensity inspiratory muscle training in athletes with lumbo-pelvic pain. Methods: A single blinded randomized clinical trial will be carried out. A total sample of 80 athletes with lumbo-pelvic pain will be recruited and randomized into 2 groups: one group will be treated by isolated high-intensity inspiratory muscle training during 8 weeks, and another group will be treated with diaphragm visual biofeedback reeducation by ultrasonography during 6 weeks in conjunction with high-intensity inspiratory muscle training during 8 weeks. Outcome measurements will be diaphragm muscle thickness evaluated by ultrasonography (main outcome measurement), pain intensity, pressure pain threshold, disability, quality of life and respiratory parameters by spirometry, which will be assessed before and after intervention.

Measured: Change from Baseline pain intensity at 8 weeks
Pressure pain threshold
Pressure pain threshold in kilograms / squared centimeter evaluated by algometer

Disability scores evaluated by the self-reported Roland-Morris Disability Questionnaire from 0 (no disability) to 24 points (Maximum disability)
Measured: Change from Baseline disability at 8 weeks
Health-related quality of life scores
Quality of life scores evaluated by the self-reported Medical Outcomes Study Short-Form 36 questionnaire from 0 (lowest health-related quality of life) to 100 (highest health-related quality of life)
Measured: Change from Baseline health-related quality of life scores at 8 weeks

Respiratory parameters percentage evaluated by spirometry
Measured: Change from Baseline respiratory parameters percentage at 8 weeks

Questions about this trial
What is this clinical trial studying?
A study testing Diaphragm ultrasonography reeducation plus inspiratory training and Isolated inspiratory training in people with Ultrasonography and Low Back Pain, run by Universidad Complutense de Madrid at 1 site in Spain.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 14 Jun 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. 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?
Diaphragm muscle thickness (time frame: Change from Baseline diaphragm muscle thickness at 8 weeks). 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 NCT04097873, which also lists 3 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 14 Jun 2022; AzTrials last refreshed its copy on 6 Nov 2026.
