“…Studies that use long periods of training (over 6 months) indicated a decrease in the weight of obese subjects COPD [57]. As demonstrated in other studies [58], no significant modification of pulmonary function was marked after a training program. The sixminute walking test results showed a significant increase in walking distance after the rehabilitation period.…”

“…30 However, a longitudinal study of patients with moderate-tosevere COPD showed that, after 3 y, the decline in FEV 1 was significantly lower in the PR group compared with the standard care group. 31 The potential of PR in delaying the decline of lung function should therefore be examined in patients with mild COPD as well.…”

“…1 Nevertheless, changes in FEV 1 in response to treatment are small in relation to its repeatability. 2,3 New clinical markers are therefore needed to evaluate the ef-fectiveness of treatments for COPD. 4 These markers should be simple in terms of measurement, interpretation, and resources used and should have acceptable reliability to ensure that the error involved in measurement is small enough to detect actual changes.…”

BACKGROUND: Computerized respiratory sounds have shown potential in monitoring respiratory status in patients with COPD. However, the variability and reliability of this promising marker in COPD are unknown. Therefore, this study assessed the variability and reliability of respiratory sounds at distinct air flows and standardized anatomic locations in subjects with COPD. METHODS: A 2-part study was conducted. Part 1 assessed the intra-subject reliability of respiratory sounds at spontaneous and target (0.4 -0.6 and 0.7-1 L/s) air flows in 13 out-patients (69.3 ؎ 8.6 y old, FEV 1 of 70.9 ؎ 21.4% of predicted). Part 2 characterized the inter-subject variability and intra-subject reliability of respiratory sounds at each standardized anatomic location, using the most reliable air flow, in a sample of 63 out-patients (67.3 ؎ 10.4 y old, FEV 1 of 75.4 ؎ 22.9% of predicted). Respiratory sounds were recorded simultaneously at 7 anatomic locations (trachea and right and left anterior, lateral, and posterior chest). Air flow was recorded with a pneumotachograph. Normal respiratory sound intensity and mean number of crackles and wheezes were analyzed with validated algorithms. Inter-subject variability was assessed with the coefficient of variation, and intra-subject reliability was assessed with the intraclass correlation coefficient (ICC) and Bland-Altman plots. RESULTS: Relative reliability was moderate to excellent for normal respiratory sound intensity and mean number of crackles (ICC of 0.66 -0.89) and excellent for mean number of wheezes (ICC of 0.75-0.99) at the 3 air flows. Absolute reliability was greater at target air flows, especially at 0.4 -0.6 L/s. Inter-subject variability was high for all respiratory sound parameters and across locations (coefficient of variation of 0.12-2.22). Respiratory sound parameters had acceptable relative and absolute intra-subject reliability at the different anatomic locations. The only exception was the mean number of crackles at the trachea, for which both relative and absolute reliability were poor. CONCLUSIONS: Respiratory sound parameters are more reliable at an air flow of 0.4 -0.6 L/s and are reliable overall at all anatomic locations. This should be considered in future studies using computerized auscultation.
