Description: Twenty-seven patients with mild to moderate chronic bronchitis and emphysema were studied to determine the reproducibility of incremental threshold loading in these patients. They underwent four weekly repeated measures using a two minute, fifty gram staged incremental threshold loading test. There was a significant learning effect between visits one and two. Visits two through four showed no systematic differences, however there was a random error equal to one stage (50 grams or 10 cm H2O). There was a significant difference in the load that men and women could tolerate but no difference between patients with mild and moderate to severe disease. There was no difference in how each group learned or repeated the test. There was a trend in breathing pattern that indicated the onset of inspiratory muscle fatigue at the end of the test but no differences in breathing pattern among visits.
