Minimal Clinically Important Difference of Average Daily Steps Measured Through a Consumer Smartwatch in People With Mild-to-Moderate Parkinson Disease: Cross-Sectional Study

Background: Recent studies demonstrated the validity, reliability and accuracy of consumer smartwatches for measuring daily steps in people with Parkinson’s disease (PwPD). However, no study to date estimated the minimal clinically important difference (MCID) for average daily steps (avDS), measured through a consumer smartwatch in PwPD. Objective: To calculate the MCID of avDS, measured through a commercial smartwatch (Garmin Vivosmart 4) in Pw…
