• A field study on respiratory muscle function and basic pulmonary mechanics was conducted at an international convention of 200 individuals with Charcot-Marie-Tooth disease. Forty patients with respiratory symptoms were evaluated; 15 had significant respiratory muscle dysfunction and 25 were normal. The results suggest that proximal upper limb involvement in individuals with Charcot-Marie-Tooth disease is a simple but significant predictor of respiratory muscle dysfunction.
