Patient Centered Home Exercise Program for Peripheral Artery Disease

Inclusion Criteria: 1. Participants with an ankle brachial index (ABI) ≤ 0.90 will be eligible for participation. 2. Participants with an ABI \> 0.90 but ≤ 1.00 who experience a 20% drop in ankle pressure after the heel-rise exercise will be eligible. 3. Participants with an ABI \> 0.90 who have medical record evidence of prior lower extremity revascularization for PAD will be eligible 4. Participants with an ABI \> 0.90 who have medical record evidence of PAD based on non-invasive vascular laboratory testing or based on angiographic findings will be eligible. Non-invasive vascular laboratory evidence of PAD must be obtained from a vascular laboratory. Exclusion Criteria: 1. Above or below knee amputation, critical limb ischemia, wheelchair confinement, foot ulcer, non-English speaking, significant visual impairment that interferes with walking activity, hearing impairment that interferes with full study participation, unable to return to the medical center or fitness center at the expected visit frequency, or unwilling to use technology required for the intervention. 2. Individuals whose walking is limited by a condition other than PAD. 3. Greater than class II NYHA heart failure or angina. Increase in angina, angina at rest, abnormal baseline stress test. 4. Major surgery including lower extremity revascularization or orthopedic surgery during the prior three months or anticipated in the next nine months. 5. Major medical illness including lung disease requiring oxygen, Parkinson's disease that impairs walking ability, or cancer requiring treatment in the prior two years (potential participants may still qualify if they were diagnosed with non-melanoma skin cancer in the past two years or if they have had treatment for an early stage cancer in the past two years and the prognosis is excellent). 6. Heart attack, stroke, or coronary artery bypass surgery in the last 3 months. 7. Mini-mental status examination score \< 23, dementia, or psychiatric illness. 8. Currently walking regularly for exercise at a level comparable to the amount of exercise prescribed in the intervention 9. Currently enrolled in another clinical trial, exercise trial, or in cardiac rehabilitation. Currently enrolled in a clinical trial or current participation in cardiac rehabilitation or a trial of a therapeutic intervention within the past three months. For a clinical trial of a stem cell or gene therapy intervention, potential participants will be potentially eligible immediately after the final study visit for the clinical trial, so long as s at least six months has passed since the participant received their final treatment in the stem cell or gene therapy study . 10. Deemed a poor candidate for the study or poorly suited for the intervention (at PI discretion).
