The Effects of Respiratory Muscle Strength Training (RMST) on Inspiratory and Expiratory Muscle Strength in Adults and Children With Pompe Disease
The purpose of the study is to determine if respiratory muscle strength training will be beneficial for inspiratory and expiratory muscle strength in adults and children with Pompe disease.

Adults and children with Pompe disease.
|Other: respiratory muscle strength training|
Respiratory muscle weakness results in substantial morbidity and mortality in individuals with almost all forms of neuromuscular disease (NMD), including both the infantile and adult phenotypes of Pompe disease. Although individual patterns of involvement vary, respiratory weakness in Pompe disease typically affects both the inspiratory and expiratory muscle systems. Our pilot data in two individuals with late-onset Pompe disease suggest that RMST may be a treatment for the progressive respiratory weakness encountered in this condition.
Purpose of the Study
- Determine the effect of respiratory muscle strength training on maximum inspiratory pressure, maximum expiratory pressure, upright % predicted forced vital capacity, and aspects of cough function.
- Determine the effect of RMST on functional outcome measures of gross motor function appropriate for individual participants in terms of age and motor skills.
