Geriatric Physical Therapy (GCS) Practice Test

Question: 1 / 410

At what ABI score is claudication typically experienced?

0.3 to 0.5

1.5 to 2.0

0.5 to 0.9

Claudication is typically experienced at an ankle-brachial index (ABI) score ranging from 0.5 to 0.9. This range indicates a significant degree of peripheral arterial disease (PAD), where blood flow to the extremities is compromised, leading to symptoms such as pain or cramping in the legs during physical activity. As the ABI value decreases within this range, it suggests worsening arterial insufficiency, which correlates directly with the onset of claudication.

Scores below 0.5 often indicate more severe arterial occlusion, prompting even more severe symptoms or rest pain, while scores above 0.9 are usually considered indicative of normal or acceptable arterial circulation. Therefore, the range of 0.5 to 0.9 is specifically associated with the presentation of claudication symptoms in patients.
