New app could help track muscle fatigue in cystic fibrosis patients
NCT ID NCT07135869
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a mobile app can reliably measure muscle fatigue in people with cystic fibrosis (CF). Researchers compared 100 participants with CF to healthy controls using a chair-rising test captured by the app. The goal was to see if the app could detect differences in muscle fatigue and recovery, potentially offering a low-cost tool for clinics.
