Daily Step-based Exercise Using Fitness Monitors for Peripheral Artery Disease

Completed · Not applicable

Conditions studied: Peripheral Artery Disease

In brief

Peripheral artery disease (PAD) is caused by blockages in the leg arteries. PAD limits patients' walking ability and quality of life. For patients with PAD, home exercise programs can improve walking ability and quality of life. In many patient populations, walking more than 5,000 steps a day is associated with better health. Currently, the benefit of walking more than 5,000 steps a day in patients with PAD has not been well studied. The purpose of this clinical trial is to compare two different home exercise programs in patients with PAD: walking at least 5,000 steps a day with the help of fitness monitors vs. walking 45 consecutive minutes for 3 to 5 days a week (a common exercise prescription for PAD). This study has the potential to demonstrate that, with the help of fitness monitors, walking at least 5,000 steps a day can improve walking ability and quality of life for patients with PAD.
