Thoracoabdominal asynchrony associates with exercise intolerance in fibrotic interstitial lung diseases

Background and objective The precise coordination of respiratory muscles during exercise minimizes work of breathing and avoids exercise intolerance. Fibrotic interstitial lung disease (f‐ILD) patients are exercise‐intolerant. We assessed whether respiratory muscle incoordination and thoracoabdominal asynchrony (TAA) occur in f‐ILD during exercise, and their relationship with pulmonary function and exercise performance. Methods We compared...
