Remote ischemic conditioning: Promising potential in wound repair in diabetes?

Remote ischemic conditioning involves the use of a blood pressure cuff or similar device to induce brief (3-5 min) episodes of limb ischemia. This, in turn, seems to activate a group of distress signals that has shown the potential ability to improve healing of the heart muscle and other organ systems. Until recently, this has not been tested in people with diabetic foot ulcers. The purpose of this review was to provide background on remote ischemic conditioning and recent data to potentially support its use as an adjunct to healing diabetic foot ulcers and other types of tissue loss. We believe that this inexpensive therapy has the potential to be deployed and incorporated into a variety of other therapies to prime patients for healing and to reduce morbidity in patients with this common, complex, and costly complication.
