Official Title: Respiratory Muscle Training in Late-Onset Pompe Disease
Brief Summary: This study is being done to test the effects of respiratory muscle training (RMT) in patients with late-onset Pompe Disease (LOPD) who have weakness of their breathing muscles. The results of this study will help design future research studies about RMT in LOPD. The goals of this study are to decide if sham-RMT is a useful control condition for RMT and to choose the best ways to measure the health benefits of RMT in LOPD.
