About this study

Official title: A Community-based Exercise Program to Improve Walking Outcomes in Patients With Peripheral Artery Disease

The primary aim of the study is to determine the effect of a community-based walking exercise program with detailed training, monitoring, and coaching (TMC) exercise components enhanced by community-based participatory research (CBPR) practices (TMC+) on the primary outcome of peak walking time (PWT) in patients with peripheral artery disease (PAD).

Read the detailed description

The investigators will test the hypothesis that PAD patients randomized to the exercise program in the community setting incorporating TMC+ will improve walking ability compared with patients who receive the standard of care (exercise advice). Secondary hypotheses include a significant improvement in patient-reported outcomes, an improvement in functional ability or a significant increase in volume of physical activity for patients who complete community-based walking exercise when compared with patients receiving the standard of care. Exploratory hypotheses include a significant improvement in PWT for 1) patients receiving a combination of lower extremity endovascular therapy (ET) and community-based walking exercise or 2) open peripheral intervention and community-based walking exercise compared to patients who do not receive endovascular therapy or open intervention and receive only the standard of care.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Exercise therapyBehavioural

    The exercise therapy program with training, monitoring and coaching enhanced by community-based participatory research (CBPR) (TMC+) is a comprehensive approach to community-based walking exercise for improving PAD patient outcomes. The components of TMC+ are optimal training guidelines for patients (i.e., T), monitoring from both investigators and patient self-monitoring (i.e., M), coaching from investigators on how to improve patients' walking ability (i.e., C), and finally enhancements from CBPR practices (+).

  • lower extremity ETProcedure or surgery

    catheter-based revascularization of peripheral arteries (background treatment part of standard clinical care at hospital)

  • peripheral open interventionProcedure or surgery

    revascularization of lower extremities with open bypass surgery (background treatment part of standard clinical care at hospital)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in peak walking time (PWT)

    Measured: Baseline, post-revascularization (ET or open intervention) (4 weeks, if applicable), post-12 weeks (exercise and control groups), 6 months following intervention time period

Secondary outcomes (6)
  1. Change in claudication onset time (COT)

    Measured: Baseline, post-revascularization (ET or open intervention), post-12 weeks (exercise and control groups), 6 months following intervention time period

  2. Change in patient-reported outcomes

    Measured: Baseline, post-revascularization (ET or open intervention), post-12 weeks (exercise and control groups), 6 months following intervention time period

  3. Change in peak oxygen uptake

    Measured: Baseline, post-revascularization (ET or open intervention), post-12 weeks (exercise and control groups), 6 months following intervention time period

  4. Change in functional ability

    Functional ability will be assessed with the 6-min walk test and Short Physical Performance Battery which consists of 1) walking short distances, 2) completing balance tests and 3) sit and standing from a chair 5 times.

    Measured: Baseline, post-revascularization (ET or open intervention), post-12 weeks (exercise and control groups), 6 months following intervention time period

  5. Evaluation of total volume of activity

    Measured: post-12 weeks (exercise and control groups)

  6. Evaluation of exercise adherence

    For patients randomized to the exercise therapy group

    Measured: post-12 weeks (exercise and control groups)

Questions about this trial

What is this clinical trial studying?

A study testing Exercise therapy, lower extremity ET and peripheral open intervention in people with Peripheral Artery Disease, run by University of Minnesota at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 24 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 22 Apr 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in peak walking time (PWT) (time frame: Baseline, post-revascularization (ET or open intervention) (4 weeks, if applicable), post-12 weeks (exercise and control groups), 6 months following intervention time period). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Apr 2020.
