Peripheral artery disease (PAD) affects more than 200 million people worldwide and is associated with substantial morbidity and lower extremity symptoms. Evidence showed that supervised treadmill exercise improved walking performance and functional capacity in these patients. Despite the benefits, less than 1 in 50 patients with PAD are referred for supervised exercise in the U.S. Participating in supervised exercise therapy requires patients to attend multiple weekly sessions and specialized centers, and many patients with PAD decline to participate due to the inconvenience. Past studies done by our team showed the utility of gamification and behavioral economics to increase physical activity as part of a home-based walking program. A home-based walking intervention using gamification and behavioral economics to increase physical activity has not yet been studied for patients with PAD.
We designed a 6-month randomized controlled trial aimed at assessing whether a home-based walking program with automated coaching augmented with gamification and behavioral economic principles improves functional capacity in patients with PAD. Patients with PAD will use a wearable device to establish a baseline step count and monitor activity during the trial.
This study is currently in progress.
