A study compared two Fitbit® smartwatch models and medical devices (accelerometer, heart monitor, etc.) frequently used in clinical trials, in 110 people with neuromuscular diseases:
- Fitbit® wristbands are well tolerated and more economical. They are adequate for evaluating and monitoring physical activity in daily life.
- The authors point out that there are deviations from the data provided by medical devices, whether on the number of steps taken, heart rate or number of calories burned.
- Please note that the “active minutes” data provided by the Fitbit® app does not correspond to those obtained from the MVPA (Moderate to Vigorous Physical Activity), a reference tool for measuring physical activity in the general population.
