An April 2021 study by Northwestern University Feinberg School of Medicine said,
"We've shown you have to walk to elicit ischemic leg pain to reap the benefits,"
"It will lessen over time, and most people eventually will be able to walk further without discomfort."
"Perhaps for people with Peripheral Artery Disease, the exercise promotes growth of new small blood vessels to their muscles,"
"Patients with Peripheral Artery Disease should be advised to walk for exercise at a pace that induces ischemic leg symptoms in order to get a benefit,”
"Exercise is the most effective non-invasive therapy to improve walking in people with Peripheral Artery Disease."
