Hill Test

The Hill Test (pronounced: /hɪl tɛst/) is a medical test used to evaluate the blood flow in the lower extremities. It is named after the British physician Leonard Hill, who first described the procedure in the early 20th century.

Etymology

The term "Hill Test" is derived from the name of Leonard Hill, a British physiologist known for his work on blood pressure and circulation. The test was named in his honor due to his significant contributions to the field of physiology.

Procedure

The Hill Test involves the patient lying flat while the physician measures the blood pressure in both the arm and the ankle. The ankle-brachial index (ABI) is then calculated by dividing the ankle pressure by the arm pressure. A normal ABI is 1.0 or greater. An ABI of less than 0.9 indicates Peripheral Artery Disease (PAD), a condition in which the arteries in the legs or arms are narrowed or blocked.
