Overview
Brief Summary
Vascular claudication is a common cause of functional limitation. This painful condition is a source overall muscle deconditioning in the peripheral arterial diseased (PAD) patient leading gradually to a state accented inactivity. The characterization of the claudication as it results from a proximal or distal ischemia has never carried out. Investigators will analyze dynamic pedometer parameter throughout walking tests in PAD patients with claudication
Detailed Description
Patients referred for exercise tests on treadmill for the quantification of walking ability will gave a recording of their walking parameters through an instrumented treadmill recording biomechanic parameters (surface electromyography, walking pace; force of the foot/treadmill interface, length of the step.. etc.) Analysis will be performed until walking is stopped due to usual claudication during a constant load 2 miles per hour 10% slope treadmill procedure.

Outcomes
Primary Outcomes
Root mean square (RMS) of the electromyogram signal
Time Frame: Evaluation is complete immediately at the end of each walking test. (The end of the walking period is the end of participation of each patient, no follow up of patients)
Calculation for the difference (change) in RMS value at the end vs.beginning of the walking test (RMS is calculated over 15 sec at rest and 15 sec just before the end of the walking period)
