Duscha BD, et al. - Researchers compared functional capacity and physical activity patterns among peripheral artery disease (PAD) patients with intermittent claudication (IC) randomized into usual care or a 12-week mobile health (mHealth) intervention consisting of patient education, smartphones and physical activity trackers. They found that peak VO₂ and claudication onset time in PAD patients with IC were significantly improved after a 12-week mHealth intervention, while no such benefits were seen with usual care. Furthermore, for those patients who cannot participate in the supervised exercise, the mHealth interventions are considered as a promising alternative therapy.
