Claudication, Systematic Evaluation of Limp on Treadmill

Claudication et Fatigue Musculaire de l'artériopathe

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

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.
