Establishing the practical feasibility of expiratory muscle strength training (EMST) for individuals with Progressive Supranuclear Palsy (PSP)

Background: Individuals with Progressive Supranuclear Palsy (PSP), a form of atypical parkinsonism, often present with swallowing, cough, and respiratory dysfunction. Expiratory muscle strength training (EMST) is a well-studied treatment approach to improve airway protection in various neurodegenerative diseases. However, to our knowledge, no studies have examined the feasibility of EMST as a treatment for airway protection in individuals with PSP. This study examines the feasibility of EMST for airway protection in this population.
