---|---|
Experimental: Intervention group, PiezoRx device
Participants will use the PiezoRx pedometer at leisure for 12 weeks, and receive the standard care of the FrancoForme cardiac prevention and rehabilitation program.
|
Device: PiezoRx medical grade pedometer
Participants will be asked to freely use the PiezoRx medical grade pedometer for 12 weeks. Participants have access to a personal account created online and can record the daily steps count and physical activity. Participants will receive the standard care by the FrancoForme Cardiovascular rehabilitation and prevention program |
No Intervention: Control group, Standard care
Participants will receive the standard care of the FrancoForme Cardiovascular disease prevention and rehabilitation program.

- Change in number of participants who use the PiezoRx device [ Time Frame: One year (Baseline to 12 weeks, and baseline to 52 weeks) ]The number of participants who use the device will be defined as the number of participants who create and use the online account during the trial.
- Change in frequency of using the PiezoRx device [ Time Frame: One year (Baseline to 12 weeks, and baseline to 52 weeks) ]The frequency of usage will be defined as the number of times the participants logon into the online account to upload the steps count and/or physical activity levels.
- Changes in moderate to vigorous physical activity time [ Time Frame: One year (Baseline to 12 weeks, and baseline to 52 weeks) ]Changes in levels of moderate to vigorous physical activity (in minutes per week) from baseline to follow-ups will be measured by the PiezoRx device.
- Number of participants that continue wearing the PiezoRx device beyond the 3 month intervention [ Time Frame: One year ]The number of participants who continue wearing the PiezoRx device beyond the 3 month intervention will be defined as the number of participants who continue to use the online account.
- Validation of Physical activity questionnaire [ Time Frame: One year ]Self-reported physical activity (in minutes/day) using the physical activity questionnaire.
- Validation of Physical activity questionnaire [ Time Frame: One year ]Self-reported sitting time (in minutes/day) using the physical activity questionnaire.
- Analysis of physical activity data (hrs/min) recorded by PiezoRx device and ActiGraph accelerometer and comparing the values. [ Time Frame: 7 days ]Data recorded from PiezoRx device and ActiGraph accelerometer will be collected for 7days. Values will be compared to validate the PiezoRx device against the ActiGraph.
- Changes in blood pressure [ Time Frame: One year (Baseline to 12 weeks, and baseline to 52 weeks) ]Changes in blood pressure (mmHg) from baseline to from baseline to follow-ups
- Changes in blood lipids [ Time Frame: One year (Baseline to 12 weeks, and baseline to 52 weeks) ]Changes in total cholesterol, HDL, LDL, and Triglycerides (mmol/L) from baseline to follow-ups
- Changes in fasting glycosylated hemoglobin [ Time Frame: One year (Baseline to 12 weeks, and baseline to 52 weeks) ]Changes in fasting blood HbA1c (%) from baseline to follow-ups
- Changes in body weight [ Time Frame: One year (Baseline to 12 weeks, and baseline to 52 weeks) ]Changes in body weight (kg) from baseline to follow-ups
- Changes in body mass index [ Time Frame: One year (Baseline to 12 weeks, and baseline to 52 weeks) ]Changes in BMI (kg/m2) from baseline to follow-ups
- Changes in waist circumference [ Time Frame: One year (Baseline to 12 weeks, and baseline to 52 weeks) ]Changes in waist circumference (cm) from baseline to follow-ups
- Changes in resting heart rate [ Time Frame: One year (Baseline to 12 weeks, and baseline to 52 weeks) ]Changes in resting heart rate (bpm) from baseline to follow-ups
- Changes in anxiety and depression [ Time Frame: One year (Baseline to 12 weeks, and baseline to 52 weeks) ]Changes in measures of anxiety and depression as assessed using the Hospital Anxiety and Depression Scale from baseline to follow-ups
