Effect of Personal Activity Intelligence (PAI) monitoring in the maintenance phase of cardiac rehabilitation: a mixed methods evaluation

The purpose of this exploratory study was to determine how monitoring (Personal Activity Intelligence) PAI via a (Wearable Physical Activity Monitoring Device) WPAM could increase the amount and/or intensity of physical activity for individuals in the maintenance phase of cardiac rehabilitation (CR). The study also investigated participants’ perceptions of this particular approach.

A total of twenty CR participants, both male and female, completed the study. Out of 20 eligible participants between the ages of 18-80 in the maintenance phase of cardiac rehab, 18 were included in the quantitative data, whilst 20 were included in the qualitative. Participants’ heart rates were converted to PAI Scores, and they were monitored daily via a WPAM. Participants were blinded to their PAI Scores during the first three weeks of the study, then un-blinded for the remaining three weeks. PAI data was collected daily throughout the six weeks.

Using a concurrent mixed-methods approach, researchers employed thematic framework analysis to identify three global themes including: participants’ perceptions about the WPAM, PAI and various factors, including barriers to exercising.

Once participants were educated about PAI and able to view their personal data, motivation to exercise increased and moderate increases were noted. Once “unblinded” and educated about PAI, participants were given access to their individual data. Based on the quantitative data analysis:

  • 89% of the participants increased their PAI Scores
  • 42% increase in PAI Scores on average
  • 39% increase in participants who achieved 50 PAI or more at three weeks
  • 61% increase in participants who achieved 50 PAI or more at six weeks

The concept of PAI was described by CR participants as being an “interesting”, “beneficial” and “motivating”. 80% of participants believed they would continue to use this approach in the longterm, if the functionality and aesthetics of the wearable device were improved upon.

Notably, all participants agreed that they would recommend PAI monitoring to others. Aside from serving as a motivating factor for some, participants cited the tool’s capacity to offer individualized data, as a reason for recommendation. Ultimately, this study suggests that monitoring PAI via a WPAM may be a “viable strategy” in the maintenance of exercise adherence for individuals with cardiac rehabilitation.
