PAIn Study: Personal activity intelligence (PAI) e-health program in people with diabetic peripheral neuropathy

Participants with diabetic peripheral neuropathy (DPN) not currently meeting exercise guidelines were recruited into a 12-week prospective cohort study. Participants used a wrist-worn heart rate monitor and smartphone app to provide personalised information on physical activity accumulated over the previous seven days (PAI score). In weeks 1-4 (phase 1), participants attended weekly 2-hour e-health sessions involving exercise and behaviour-change counselling. In weeks 5-12 (phase 2), participants performed self-directed exercise. Program completion rates, satisfaction, PAI scores and adverse events were recorded. Ecological momentary assessment was used to evaluate changes in DPN symptoms and effect sizes.
