Title : Does ‘IS’ affect the two strength and endurance spirometric indices in COPD patients as the ‘IMT’ trainings?
Abstract:
Purpose: Respiratory muscle weakness is one of the most important features of patients with chronic obstructive pulmonary disease, which can lead to clinical symptoms. Inspiratory resistive muscle training is a well known technique which has been shown to improve both muscle strength (PImax) and endurance (MVV) in patients with chronic obstructive lung disease. This study aimed to examine the effect of incentive spirometry on Strength and Endurance Indices of pulmonary muscles in COPD patients and compare its efficacy to inspiratory resistive muscle training using power breathes.
Design: Randomized controlled trial.
Methods: Thirty patients with moderate COPD, from a general hospital in Mashhad, Iran, were randomly assigned into two study groups. All subjects trained daily in two 15-minute sessions, 4 days a week, for 4 weeks. PImax, and MVV tests were compared before interventions and at the end of weeks 2 and 4. Analysis of variance with repeated measures used for analyzing by SPSS software.
Findings: Meanwhile a significant improvement in the mean values of PImax and MVV in both groups (P ≤ .01), The IMT technique was more efficient to improve MVV (41/5% versus 22/5%, P ≤ .05) and PImax (21% versus 6/9%, P ≤ .05).
Conclusions: Despite the superiority of IMT training for PImax and MVV indices, Incentive spirometry due to the positive changes within the group for the two indicators can be considered as an effective component for pulmonary rehabilitation in COPD patients.
Takeaway Notes:
1. It helps nurses or other medical professions to provide the right training for each patient according to the nature of the disease.
2. It provides a platform for medical researchers in this area.
3. Patients deserve to have the best care, so it may help them to reach a better life style through such trainings.
