What You Need to Know Before You Apply

What is the purpose of this trial?

Peripheral artery disease (PAD) is a highly prevalent condition affecting up to 10% of Veterans that leads to loss of walking ability and increased risk of amputation. Veterans have limited access to supervised exercise therapy, a facility-based program proven to improve walking ability in PAD, which is poorly attended due to the inconvenience and cost of attending a 12-week program with multiple weekly sessions. This CDA-2 application will investigate the feasibility of home-based exercise therapy (HBET) delivered using mobile health (mHealth) technologies in Veterans with symptomatic PAD. We will partner with the MOVE! program to deliver HBET through group behavioral coaching and a novel wearable activity monitor in a newly proposed program called Smart MOVE!. There is a clear need to provide effective and convenient alternatives to supervised exercise for Veterans with PAD. This study will provide evidence to proceed with Smart MOVE!, a much-needed patient-centered rehabilitation program for Veterans with PAD.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It is best to discuss this with the study team or your healthcare provider.

Is mobile health-supported exercise therapy safe for people with peripheral artery disease?

Home-based exercise programs for people with peripheral artery disease, like those supported by mobile health, appear to be safe with a very low rate of adverse events. In a review of 1642 participants, only four related adverse events were reported over 147,810 patient-hours, suggesting these programs are generally safe. ^{1 2 3 4 5}

How is Mobile Health-Supported Exercise Therapy different from other treatments for Peripheral Artery Disease?

Mobile Health-Supported Exercise Therapy is unique because it uses a smartphone app to support and motivate patients to perform exercise therapy at home, which can increase adherence and improve walking distances and quality of life without the time and cost constraints of traditional supervised exercise in a clinical setting. ^{6 7 8 9 10}

What data supports the effectiveness of this treatment for Peripheral Artery Disease?

Research shows that exercise therapy can significantly increase the distance patients with peripheral artery disease can walk without pain. Programs that include supervised or home-based exercise have been successful in improving physical performance and social and psychological functions in these patients. ^{8 11 12 13 14}

Published Research Related to This Trial

A personalized reconditioning exercise program combined with therapeutic education for patients with peripheral artery disease (PAD) led to significant improvements in quality of life (QoL) and functional parameters over 12 months, with SF-36 scores showing stable enhancement.

Patients demonstrated notable increases in walking distances, with initial claudication distance improving by 203% and absolute claudication distance improving by 84% after 6 months, indicating the program's effectiveness in managing PAD symptoms.

Active exercise therapy significantly improves outcomes for patients with early stages of peripheral arterial occlusive disease (PAOD), as demonstrated in a successful outpatient claudication group program involving 26 patients.

The use of a newly developed pedal ergometer allowed for controlled endurance training, resulting in a notable increase in pain-free walking distance for 17 out of the 26 participants, supported by improvements in arterial hemodynamics.

Both low-intensity and high-intensity exercise rehabilitation programs significantly improved physical function and health-related quality of life in patients with peripheral arterial disease (PAD), with similar outcomes after 6 months of training.

Patients in both groups experienced a remarkable increase in claudication distance (over 100% improvement), indicating that low-intensity exercise can be as effective as high-intensity exercise for enhancing functional independence in PAD patients.

A 6-month randomized controlled trial involving 194 patients with peripheral artery disease (PAD) showed that a home-based walking exercise program significantly improved self-efficacy, satisfaction with physical functioning, pain acceptance, and social functioning compared to a control group.

These improvements occurred independently of changes in walking performance, suggesting that the cognitive behavioral approach of the intervention effectively enhanced patients' psychological and social well-being related to their condition.

Home-based exercise therapy significantly increased the number of steps walked by patients with peripheral arterial disease (PAD) after endovascular therapy (EVT), indicating improved physical activity levels.

The intervention also positively impacted quality of life, as evidenced by significant improvements in pain and speed scores on quality of life questionnaires three months post-surgery.

Home-based exercise programs (HBEPs) for individuals with intermittent claudication (IC) are safe, with only four adverse events reported over 147,810 patient-hours, resulting in a complication rate of one event per 36,953 patient-hours.

Most adverse events were cardiac-related and occurred during high levels of claudication pain, suggesting that while HBEPs are generally safe, monitoring and possibly cardiac screening may be beneficial for those engaging in more intense exercise.

A 12-week app-based exercise therapy program for patients with peripheral artery disease (PAD) and intermittent claudication (IC) was successfully implemented, with an impressive 86% completion rate among 139 participants.

The program not only facilitated significant physical activity, with participants logging over 201,000 minutes of walking, but also helped 92% of participants achieve their specific health goals, demonstrating its effectiveness and feasibility, especially in settings lacking traditional exercise therapy options.

In a study of 210 participants with peripheral artery disease (PAD), a 6-month supervised exercise therapy (SET) program significantly reduced systolic blood pressure by 12 mm Hg, pulse pressure by 9 mm Hg, and heart rate by 7 beats per minute during exercise compared to a control group.

The improvements in cardiovascular health metrics (blood pressure and heart rate) were associated with better walking performance, indicating that SET not only enhances walking ability but also positively impacts cardiovascular health in individuals with PAD.

Only 30.4% of vascular surgeons reported access to supervised exercise programs (SEPs) for managing peripheral arterial disease (PAD), highlighting a significant accessibility issue.

Structured home-based exercise programs (HEPs) were found to be effective alternatives, significantly improving functional capacity and quality of life compared to standard advice, although SEPs were superior in some cases.

A supervised exercise therapy (SET) program with at least two sessions per week, each lasting over 30 minutes, significantly improves walking distance in patients with intermittent claudication after 3 and 12 months, based on a study of 169 patients.

The analysis indicates that a total of at least 590 minutes of training in the first 3 months is optimal for enhancing walking distance, with no significant differences found between different types of exercises or training formats.

This study will evaluate the effectiveness of a mobile health tool, specifically a smartphone app with a virtual assistant, in improving adherence to home-based exercise therapy (HBET) for patients with peripheral arterial disease (PAD) and intermittent claudication (IC) over a 6-month period with 300 participants.

The primary goal is to measure changes in walking distances, and the results will help determine if the virtual assistant can significantly enhance motivation and behavior change compared to a standard practice diary, potentially improving patient outcomes and self-management in chronic conditions.
