Patients diagnosed with metabolic syndrome were recruited and prescribed to live for 12 weeks using a wrist-wearable device (B.BAND, B Life Inc, Korea). The block randomization method was used to distribute the participants between an intervention group (n=35) and control group (n=32). In the intervention group, an experienced study coordinator provided feedback on physical activity to individuals through telephone counseling every other week.
