What does claudication mean?
Claudication is a medical term for pain, cramping, or weakness in the leg muscles brought on by exercise and relieved by rest. It arises when the muscles receive too little blood to meet their demand — most commonly because of peripheral artery disease, where narrowed arteries restrict circulation. Doctors call this pattern intermittent claudication, and it typically affects the calf, thigh, or buttocks after a predictable amount of walking. A related form, neurogenic claudication, stems from nerve compression in the lower spine rather than poor blood supply. The word derives from Latin claudicare, meaning 'to limp,' so it literally names the limping gait sufferers adopt to ease the discomfort. Though unfamiliar to many, claudication is an important warning sign of cardiovascular disease, and recognizing it can prompt early diagnosis and treatment of underlying arterial blockages.
nounPain, cramp, or weakness in the leg muscles caused by an inadequate blood supply during exercise, relieved by rest (intermittent claudication); by extension, a limp or lameness of any origin.
- Exercise-induced pain, cramping, or weakness in the leg muscles caused by insufficient blood flow, typically relieved by rest — most often seen as 'intermittent claudication' in peripheral artery disease.
- A limp or difficulty in walking arising from any cause, including neurological conditions such as spinal stenosis ('neurogenic claudication').
"The patient reported claudication after walking only half a block, a classic sign of peripheral artery disease."
"He was diagnosed with intermittent claudication after complaining of calf pain every time he climbed stairs."
"The neurologist distinguished her neurogenic claudication from vascular disease by noting that the symptoms eased when she bent forward."
The plural is rare and confined largely to clinical literature describing multiple distinct episodes or cases of claudication.
"The study compared claudications reported by diabetic and non-diabetic patients."
It comes straight from the Latin for 'to limp' — the same root that gave the Roman emperor Claudius his mocking surname, since he walked with a limp.

Etymology of claudication
Claudication comes from the Latin verb claudicare, meaning 'to limp' or 'to be lame,' itself derived from the adjective claudus ('lame, crippled'). It entered English medical vocabulary in the early modern period, and its enduring association with limping survives in the name of the emperor Claudius, whose family name Claudia was linked by Romans to the same root. Its clinical sense — pain-induced limping from poor limb circulation — was formalized in nineteenth-century French medicine before becoming standard in English.

How claudication is actually used
Strictly a clinical term, encountered almost exclusively in medical contexts; lay readers are unlikely to meet it outside discussions of peripheral artery disease. In modern usage it nearly always refers specifically to the vascular sense unless qualified as 'neurogenic.' The plural form appears mainly in clinical writing describing multiple episodes or presentations.
