VALIDITY OF THE FITBIT ACTIVITY TRACKER FOR MEASURING STEPS IN COMMUNITY-DWELLING OLDER ADULTS
Presenter: Paul S
This module addresses:
Question: What is the criterion validity of Fitbit step counts compared
to visual count and ActiGraph accelerometer step counts? What is the
accuracy of ActiGraph step counts compared to visual count, in communitydwelling
Conclusion: The Fitbit accurately tracked steps during the 2MWT but the
ActiGraph appeared to underestimate steps. There was strong agreement
between Fitbit and ActiGraph counted steps.
Key Practice Points:
• The Fitbit tracker is sufficiently accurate to be used among communitydwelling
older adults to monitor and give feedback on step counts.
