Pfizer tests wearable tech on kids – no pills, just play

This study looked at whether a wearable device called ActiGraph can accurately record walking patterns and physical activity in healthy children aged 3 to 17. Kids wore the device as a watch and a belt while doing simple tasks like walking at different speeds, rolling dice, and moving between activity stations. They also wore the device at home for about two weeks. The goal was to see if the device works well for future research, not to treat any disease.
