Moderate Intensity Respiratory Muscle Training (RMT) in ALS
In Brief
A clinical study evaluating Respiratory Muscle Training for ALS. Completed, enrolled 9 participants across 1 site.
Detailed Summary
Twelve adults with ALS will participate in a study involving four 3-week cycles of progressive respiratory muscle training (RMT). The investigators will measure maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP) weekly. The investigators will obtain the majority of measurements of MIP and MEP during web-based telehealth visits. Participants will be stratified into 2 groups based on baseline inspiratory muscle strength as determined by maximum inspiratory pressure (MIP): six participants with minimal to no respiratory weakness (i.e., MIP ≥ 70% predicted) and six participants with mild to moderate inspiratory weakness (i.e., MIP 40-70% predicted).
Study Details
Timeline
Interventions
Two commercially available pressure-threshold RMT devices that utilize a spring-loaded flange to provide resistance against inspiration and expiration independent of respiratory flow rate will be used to provide the necessary range of resistance. Each participant will use two RMT devices, one for IMT and one for EMT.
