ClinConnect Summary

This clinical trial is looking at how effective a new way of exercising at home can be for patients with Peripheral Artery Disease (PAD). PAD affects blood flow to the legs and can cause pain while walking, known as claudication. The usual treatment involves supervised exercise therapy, which can be hard to access. This study wants to see if using a wearable activity tracker and a mobile app can help patients exercise safely and effectively at home, compared to traditional supervised exercise.

To be eligible for the trial, participants should be newly diagnosed with claudication and have a specific measure of blood flow in their legs. They should be able to walk with or without some assistance and should not have severe conditions that limit their ability to walk. Participants will receive guidance on how to exercise at home with the help of technology, and they will be monitored to ensure the program is working for them. This study is currently recruiting participants, and it's a chance to explore new, more accessible ways to improve walking and overall health for those living with PAD.
