Home-based exercise program found ineffective for patients with peripheral artery disease

A home-based exercise program, consisting of wearable devices and telephone coaching, did not improve walking ability for patients with peripheral artery disease, according to a new Northwestern Medicine study.

The study, published in the Journal of the American Medical Association (JAMA), was led by Mary McDermott, MD, ’92 GME, the Jeremiah Stamler Professor of Medicine at Northwestern University Feinberg School of Medicine.

Peripheral artery disease (PAD), which affects up to 20 percent of people older than 60, is a condition in which blockages in blood vessels in the legs lead to pain or weakness when walking.

Previously, research has demonstrated that supervised treadmill exercise significantly improves walking ability in people with PAD, and clinical guidelines currently recommend such a program as first-line therapy. Home walking exercise activity also improves walking ability in PAD and is considered a reasonable alternative to supervised exercise by clinical guidelines — but effective interventions to date have included regular visits to the medical center.

However, regular visits to a medical center for supervised exercise can be burdensome and most patients decline to participate in supervised exercise. As such, investigators have been eager to explore more convenient interventions that would allow for at-home exercise.

“There is growing interest in using wearable activity monitors to motivate people to increase walking exercise and activity,” McDermott said.

In the current trial, investigators designed a home-based exercise program that included a wearable activity monitor and regular telephone calls from a coach. The randomized trial, which is the first of its kind, enrolled 200 participants from Northwestern, New York University and the University of Minnesota. Half of the participants received the exercise intervention, while the control group received no intervention. The primary outcome was the change in distance walked over a six-minute period.

At nine months follow-up, the investigators found there was no significant difference in walking ability between the two groups. Furthermore, the exercise intervention was associated with worsened pain that interfered with daily activities. The authors suggest that this may be because participants’ attempts to exercise resulted in greater ischemic leg symptoms, while the control group may have limited their activity to avoid symptoms, reducing pain.

The findings do not support the use of home-based exercise with wearable devices and telephone coaching without periodic on-site visits, the authors conclude.

“Further research is needed to identify home-based exercise interventions for people with PAD that are effective but are not overly burdensome — i.e., do not require frequent visits to the medical center,” McDermott said.

In January, Feinberg was awarded an American Heart Association (AHA) Strategically Focused Research Network Center dedicated to calf muscle pathology and disability in PAD. The center, led by McDermott, will conduct three studies to establish ischemia-related calf muscle pathological characteristics, with the eventual goal of identifying therapeutic interventions to prevent mobility loss in PAD.
