Claudication test is an ankle examination procedure that tests for the presence of peripheral vascular disease, intermittent vascular Claudication, popliteal artery entrapment syndrome and atherosclerosis.
Patient should be awake and cooperative for a Claudication Test.
- Patient is told to walk for a minute at a rate of 120 steps per minute or 2 steps per second.
- The examiner observes for signs of muscle weakness and cramping, pain or discomfort.
Positive Claudication Test
There is positive Claudication test when there is cramping or possible color change or palor of the leg. These could indicate peripheral vascular disease, intermittent vascular claudication, popliteal artery entrapment syndrome, atherosclerosis.
Claudication time is the time that it takes from beginning of the test to the time the patient experiences symptoms. The Claudication test allows for efficient functional measurement of the patient’s ability and degree of disability.
Because of examination room size constraints, this test is more clinically practical when performed on a treadmill.
