claudication
Pronunciation: /klɔːdɪˈkeɪʃən/
Muscle pain or cramping caused by inadequate blood flow during physical activity, typically affecting the legs.
Full Definition
Claudication, derived from the Latin word meaning 'to limp,' refers to muscle pain, cramping, or fatigue that occurs during physical exertion and is relieved by rest. This symptom results from insufficient arterial blood flow to meet the metabolic demands of exercising muscles, most commonly due to atherosclerotic stenosis or occlusion of peripheral arteries. Intermittent claudication typically affects the calf muscles but can involve the thighs, buttocks, or feet depending on the level of arterial involvement. The condition serves as a classic presentation of peripheral arterial disease and requires evaluation of the arterial circulation. Symptom severity and walking distance limitations help guide treatment decisions.
Usage
Usage note: Distinguish from neurogenic claudication caused by spinal stenosis.
