Visual feedback from the SpiroGym app for breathing training in Parkinson's

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized crossover study has participants with Parkinson's disease complete two expiratory muscle strength training (EMST) sessions at 75% of their maximum expiratory pressure, with a two-week interval between sessions. One session uses the SpiroGym mobile app to provide real-time visual feedback and the other session is performed without the app, with the order randomized. Outcomes include muscle activation measured by surface electromyography (sEMG), noise intensity recorded by SpiroGym as a proxy for expiratory performance, and participant-reported perceived difficulty and motivation. The design tests whether immediate visual feedback changes physiological effort and subjective experience during EMST.
