Few studies have defined the association of physician-patient communication with physical activity levels in patients with peripheral arterial disease. We hypothesized that a face-to-face intervention versus video watching would improve physical activity levels in patients with peripheral arterial disease. The authors conducted a randomized trial involving 2 interventions. The face-to-face intervention included a brief dialogue with patients to understand their perceptions of peripheral arterial disease and importance of walking. The comparison group watched a video that included an overview of peripheral arterial disease. The primary outcome was changed from baseline to follow-up in levels of physical activity. Fifty-one patients with peripheral arterial disease were randomized. There were no statistically significant differences between the 2 groups in reported activity level or walking ability at 12 weeks. For within group changes, the patients in the video-watching group improved their walking speed (8.5%; SD = 4.1; P = .05). Patients with peripheral arterial disease may benefit from the use of an educational video to increase the use of unsupervised physical activity. Further research is needed to identify interventions that can increase the use of unsupervised physical activity in this population.
