Brief summary: Objective: To determine the effectiveness of bilateral and simultaneous diaphragm visual biofeedback reeducation by ultrasonography in conjunction with high-intensity inspiratory muscle training versus isolated high-intensity inspiratory muscle training in patients with low back pain. Methods: A single blinded randomized clinical trial will be carried out. A total sample of 96 patients with low back 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 bilateral and simultaneous 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.
