Intermittent claudication is a cramping sensation in the legs that is present during exercise or walking and occurs as a result of decreased oxygen supply. This cramping usually occurs in the calf, but may also occur in the feet. When intermittent claudication is discussed it is measured by the number of "blocks" (e.g. 1 or 2 blocks) one can walk comfortably. It often indicates severe atherosclerosis. One of the hallmarks of this clinical entity is that it occurs intermittently. It disappears after a brief rest and the patient can start walking again until the pain recurs.

Intermittent claudication in and of itself is often a symptom of severe atherosclerotic disease of the peripheral vascular system. The term claudication derives from the Latin verb "claudicare" which means to limp. The Roman emperor, Claudius (ruling from A.D. 41-54) was named such because of his limp.
