Stretching may reduce walking pain among peripheral artery disease patients
American Heart Association News May 11, 2017
Simple calf muscle stretching may reduce leg pain when walking and increase blood flow for people living with peripheral artery disease, according to a preliminary abstract presented at the American Heart AssociationÂs Arteriosclerosis, Thrombosis and Vascular Biology | Peripheral Vascular Disease 2017 Scientific Sessions.
ÂThis is a very safe, easy intervention that can be done at home and has the potential to really improve your tolerance for walking and get you into a walking program, said Judy M. Muller–Delp, PhD, senior study author and professor of biomedical sciences at the Florida State University College of Medicine in Tallahassee.
In the current study, researchers evaluated 13 patients (six women and seven men; average age 71), most taking a statin drug and anti–platelet medications. Participants were instructed to passively stretch their calf muscle in 30–minute daily sessions using a splint that flexed the ankle about 15 percent. Walking ability and blood flow were measured after 4 weeks of calf stretching of each leg (5 days a week) and after 4 weeks without the special stretches.
Compared to a month of not stretching, after one month of daily calf stretches the participants:
ÂA physical therapist can instruct you how to adjust and wear the splints correctly so you can do the stretches at home. There is no doubt about the benefit of exercise training on blood vessel health in PAD patients. If you have limited walking ability, I recommend that you at least perform muscle stretches so you can gain enough comfort and confidence in walking to participate in a walking exercise program, said Kazuki Hotta, PhD, lead author of the study and a postdoctoral fellow in engineering science at the University of Electro–Communications in Tokyo.
According to the American Heart AssociationÂs 2017 Statistical Update, about 10 percent of people with PAD have the classic crampy pain symptom of intermittent claudication. Approximately 40 percent do not complain of leg pain, whereas the remaining 50 percent have a variety of different leg symptoms.

Compared to a month of not stretching, after one month of daily calf stretches the participants:
- improved the ability of their calf arteries to relax and expand to let blood flow through after being momentarily held back with a blood pressure cuff (a test called flow–mediated dilation), from an average of 3.7 percent to 5.2 percent  moving them into the normal range for healthy elderly people;
- extended how far they could walk in six minutes  about half a city block farther but still well below normal for people the same age; and
- prolonged the distance they could walk before needing to stop and rest due to leg discomfort.
