Trial Summary

What is the purpose of this trial?This trial is testing a smartphone-based exercise program with coaching against the usual care given by doctors. It aims to help patients with peripheral artery disease who often struggle to follow exercise routines. The smartphone program could make it easier for them to stay on track and improve their health.

Eligibility Criteria

This trial is for adults aged 18-89 with Peripheral Arterial Disease (PAD), who can consent and have specific Ankle-Brachial Index (ABI) or Toe-Brachial Index (TBI) scores indicating reduced blood flow. It's not for those whose walking is limited by other conditions, have life-threatening illnesses, severe heart failure, active behavioral issues that affect participation, or cannot attend study visits.

Inclusion Criteria

If the blood pressure in your legs is too high or too low, it should drop by at least 20% after walking on a treadmill for 1 minute.

Participant Groups
