Feasibility of Home-based Measurement of Walking Capacity Using Global Positioning System in Peripheral Artery Disease
Summary
The purpose of this study is to assess the feasibility of home-based measurement of walking capacity in peripheral arterial disease (PAD) patients, uing the Global Positioning System (GPS). This study should state if the GPS technique could be used in clinical routine in order to assess walking capacity in PAD patients. Patients will be assessed a first time (test 1) and six months later (test 2).
Description
The measurement of walking capacity in PAD patients is an important step in the management of such patients. The gold standard method to assess this walking capacity is the measurement of the maximal walking distance on a treadmill. However, treadmill measurement are not readily accessible and the relationship with free-living walking capacity is, although not well known, weak. A novel approach was developed using a Global Positioning System in order to assess community-based walking capacity. This method showed interesting results, validating the technique, but was limited to one laboratory and to the place where the measurements were performed. The next step is therefore to assess the feasibility of home-based measurement of walking capacity using the GPS technique, through a multicenter study regrouping university hospitals, independent vascular specialists (angiologists) and private clinic(s).

Medical and Biotech [MESH] Definitions
Walking
An activity in which the body advances at a slow to moderate pace by moving the feet in a coordinated fashion. This includes recreational walking, walking for fitness, and competitive race-walking.
Ankle Brachial Index
Comparison of the BLOOD PRESSURE between the BRACHIAL ARTERY and the POSTERIOR TIBIAL ARTERY. It is a predictor of PERIPHERAL ARTERIAL DISEASE.
Coronary Artery Bypass
Surgical therapy of ischemic coronary artery disease achieved by grafting a section of saphenous vein, internal mammary artery, or other substitute between the aorta and the obstructed coronary artery distal to the obstructive lesion.
Catheterization, Peripheral
Insertion of a catheter into a peripheral artery, vein, or airway for diagnostic or therapeutic purposes.
Internal Mammary-coronary Artery Anastomosis
Direct myocardial revascularization in which the internal mammary artery is anastomosed to the right coronary artery, circumflex artery, or anterior descending coronary artery. The internal mammary artery is the most frequent choice, especially for a single graft, for coronary artery bypass surgery.
