Effects of a Rehabilitation Programme with a Nasal Inspiratory Restriction Device on Exercise Capacity and Quality of Life in COPD.

Objective: The objective was to assess the effects of a nasal restriction device for inspiratory muscle training, called Feelbreathe, added to a rehabilitation program (RP) on exercise capacity, quality of life, dyspnea and inspiratory muscle strength in patients with stable COPD.

Methods: Patients were randomized into three groups, one performed a supervised RP using the Feelbreathe device (FB group), the second group developed the same RP with oronasal breathing without FB (ONB group) and the third was the control group (CG). We evaluated inspiratory muscle strength (P), dyspnea (mMRC), quality of life (CAT) and exercise capacity (6MWT) before and after 8-week of RP.
