U.S., April 25 -- ClinicalTrials.gov registry received information related to the study (NCT06942533) titled 'Effect of Visual Feedback From the SpiroGym Mobile Application' on April 09.
Brief Summary: The previous pilot study showed that two weeks of intensive expiratory muscle strength training (EMST) coupled with SpiroGym were sufficient to significantly improve the participants' voluntary peak cough flow (PCF). The improvement was quantitatively comparable to the results of other intensive EMST studies with longer durations. When interpreting such rapid improvement, the impact of SpiroGym's visual feedback was considered. It was assumed that visual feedback increased training effort compared to regular training without immediate contro...
