Brief Summary

Intermittent claudication (IC), the most common manifestation of peripheral artery disease (PAD), represents not only a significant detriment in quality of life, but also an increased risk for atherosclerotic cardiovascular disease (ASCVD), including progression of PAD, coronary artery disease (CAD) and cerebrovascular disease. Guideline directed therapy for IC includes supervised exercise, smoking cessation and optimal medical management to decrease overall risk of ASCVD. In the VA Health Care System, implementation of supervised exercise therapy through cardiac rehabilitation or physical therapy programs is limited by distances that patients must travel to VA facilities that provide these services. Furthermore, one of the most common failure points in exercise therapy programs is poor patient compliance. Improved patient participation and compliance in exercise programs for IC represents an unmet need, without which the majority of patients with life-style limiting PAD may not be receiving optimal medical management. Small studies have demonstrated the effectiveness of home-based exercise programs as an alternative to supervised exercise therapy; however, the success of the home-based exercise programs require remote coaching and/or regular provider feedback. The wide-spread availability of smart phones and smart devices has accelerated the implementation of telehealth programs that may supplement or may eventually replace in-person encounters for health care delivery. The role of provider feedback in addition to real-time feedback from smart devices remains completely unexplored. Our central hypothesis is that in individuals with IC, regular provider feedback on smart-device-based remote health monitoring data, which is available to the patient in real time, will augment the benefits of home-based exercise programs. We propose a randomized trial in patients with IC to test the central hypothesis through two Specific Aims:

  1. 1.To determine the effect of provider feedback on smart-device-based remote health monitoring data during home-based exercise programs on walking distance in patients with IC.
  2. 2.To determine the effect of provider feedback on smart-device-based remote health monitoring data during home-based exercise programs on quality of life (QOL) in patients with IC.

Outcome Measures

Primary Outcomes (1)

  • Maximal walking distance

    Change in distance to claudication onset (e.g. pain in the legs that limits walking)

    Baseline to 12 weeks

Secondary Outcomes (2)

  • Change in Quality of life measured by the VASCUQoL6

    Baseline to 12 weeks.

  • Change in Quality of life measured by the WIQ Questionnaire

    Baseline to 12 weeks.

Study Arms (2)

Remote Coaching

EXPERIMENTAL

All subjects enrolled in the study will be enrolled in supervised exercise therapy. They will also receive directions for supplemental home-based exercise and a LIVMOR remote health monitoring system. The remote coaching arm will receive regular provider feedback based on LIVMOR data.

Other: Remote Coaching

Remote health monitoring without provider feedback

NO INTERVENTION

All subjects enrolled in the study will be enrolled in supervised exercise therapy. They will also receive directions for supplemental home-based exercise and a LIVMOR remote health monitoring system. The "no intervention" arm will have access to LIVMOR data, but without provider feedback on the LIVMOR data.

Interventions

In patients randomized to the remote coaching arm, study staff will provide feedback on home-based supplemental exercise based on heart rate and walking distance measurements from the LIVMOR health monitoring system.
