Aim: To evaluate how an accelerometer and pedometer compare in measuring physical activity (PA) in children with developmental coordination disorder (DCD) and typically developing (TD) children. Methods: Children with DCD (n=7) and TD children (n=6), aged between 7 and 12 years, were included. Measurement tools were the accelerometer Actigraph (GT3X-BT), the pedometer Fitbit ZipTM and a movement diary. Step counts and time spent in sedentary, light, moderate and vigorous PA were obtained by both motion sensors. Intensity levels measured by the Actigraph were matched with reported activities from the movement diary. Results: Number of step counts significantly differed between the motion sensors for the DCD group, but not for the control group. Time spent in sedentary and light PA was different between the motion sensors for both groups. Time spent in moderate and vigorous PA was not different between the motion sensors for both groups. Conclusions: The Fitbit showed differences in step counts and time spent in lower physical activity levels compared to the Actigraph in the DCD group. It could be possible that the Actigraph was not worn during the same time period as the Fitbit, that the Fitbit was not worn at the most accurate way, or that Fitbit used another algorithm to define cut points for PA intensity levels. More research is needed to assess the validity of the Fitbit ZipTM in estimating PA in children with DCD.
