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

Abstract

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 (PImax), dyspnea (mMRC), quality of life (CAT) and exercise capacity (6MWT) before and after 8-week of RP. Results: A total of 16 patients completed the study, seven in FB group, five in ONB group and four in the CG. After the RP, the FB group showed a significant increase in PImax (93.3 ± 19.1 vs. 123.0 ± 15.8 mmHg) and in the 6MWT distance (462.9 ± 71.8 m vs. 529.1 ± 50.1 m) and a decrease in the CAT score (9.7 ± 6.5 vs. 5.9 ± 6.0) and in the mMRC dyspnea score. FB provides greater improvement in PImax, dyspnea, quality of life and 6MWT than ONB. Conclusions: The Feelbreathe® device provides greater improvements in quality of life, dyspnea, exercise capacity and inspiratory muscle strength compared to patients that did not use it.

Application of pulmonary rehabilitation in patients with pulmonary embolism (Review)

“…Although pulmonary rehabilitation is mainly applied in patients with COPD, it also includes patients with other chronic respiratory diseases, such as asthma, pulmonary hypertension, interstitial lung disease, pneumoconiosis and even those with end-stage lung disease (37). respiratory training can significantly increase the maximum inspiratory pressure and maximum tidal volume for patients with chronic respiratory diseases, eventually improving their inspiratory muscle endurance, exercise endurance and quality of life (39)(40)(41). For patients with PE, respiratory exercises should be performed if the condition permits.…”

A New Nasal Restriction Device Called FeelBreathe® Improves Breathing Patterns in Chronic Obstructive Pulmonary Disease Patients during Exercise

“…The main limitation of this study was the relatively small sample size (18 participants included in the analysis), so results must be taken with caution. However, there are several recent articles on exercise effects in COPD patients with a similar sample sizes [35][36][37][38][39]. To minimize the sample size problem, Bayesian statistics was used in this study which may produce reasonable results even with small samples.…”
