Respiratory and Peripheral Muscle Function in Cystic Fibrosis

Respiratory muscle strength (RMS) and endurance are often preserved in cystic fibrosis (CF) despite malnutrition, chronic airflow limitation, and hyperinflation. Inspiratory muscle function may be relatively preserved due to a selective "training stimulus" from chronic lung disease. Respiratory and peripheral muscle function were evaluated in 14 stable CF patients and 16 healthy control subjects. RMS was measured using static maximal pressures …
