The ankle-brachial index test compares the blood pressure measured at the ankle with the blood pressure measured at the arm. A low ankle-brachial index number can indicate narrowing or blockage of the arteries in the legs. Ankle-brachial index testing might be done before and right after walking on a treadmill.

This is done using an inflatable cuff and a hand-held ultrasound device that's pressed on the skin. The device uses sound waves to produce images and allows the pulse in the ankle arteries to be heard after the cuff is deflated.
After the procedure
The ankle-brachial index test should take only a few minutes.
