Ultrasonography Biofeedback for Diaphragm Training in Athletes With Non-specific Lumbo-pelvic Pain

Not Applicable

Completed

• Conditions: Low Back Pain; Ultrasonography
• Interventions: Other: Diaphragm ultrasonography reeducation plus inspiratory training; Other: Isolated inspiratory training

• Registration Number: NCT04097873
• Lead Sponsor: Universidad Complutense de Madrid

Brief Summary

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.

Primary Outcome Measures

Name	Time	Method
Diaphragm muscle thickness	Change from Baseline diaphragm muscle thickness at 8 weeks	Diaphragm muscle thickness in centimeters evaluated by ultrasonography

Secondary Outcome Measures

Name	Time	Method
Pain intensity	Change from Baseline pain intensity at 8 weeks	Pain intensity scores evaluated by the Visual Analogue Scale from 0 (No pain) to 100 millimeters (Worst pain)
Pressure pain threshold	Change from Baseline pressure pain threshold at 8 weeks	Pressure pain threshold in kilograms / squared centimeter evaluated by algometer
Disability	Change from Baseline disability at 8 weeks	Disability scores evaluated by the self-reported Roland-Morris Disability Questionnaire from 0 (no disability) to 24 points (Maximum disability)
Health-related quality of life scores	Change from Baseline health-related quality of life scores at 8 weeks	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)
Respiratory parameters percentage	Change from Baseline respiratory parameters percentage at 8 weeks	Respiratory parameters percentage evaluated by spirometry
