Home-Based Inspiratory Muscle Training as Stand-Alone Therapy in COPD: A Randomized Sham-Controlled Trial Assessing Novel and Established Training Methods
This randomized controlled trial evaluated the effectiveness of two home-based, stand-alone inspiratory muscle training (IMT) modalities - inspiratory flow-resistive loading with biofeedback (IRFL) and mechanical threshold loading (MTL) - compared to a sham MTL group for improving inspiratory muscle performance and functional exercise capacity in COPD patients.
