Under normal conditions systolic ankle blood pressure exceeds that at the arm at rest and one minute after exercise, thus rendering the arm-ankle difference negative. In the presence of arterial obstructions this difference is positive at rest or becomes positive after exercise. To determine its value and applicability in a given case, several ways of stress testing have been compared. On average the increase in pressure difference produced by 100 m exercise on a treadmill ergometer over pressure difference at rest followed the equation: delta P100m = 1.53 delta PR + 24.8 mm Hg, r = 0.92. The increase after maximum or 200 m exercise and that after standardized tip-toeing was comparable. Postocclusive reactive hyperemia produced a smaller but still significant increase. When patients were compared after 100 m treadmill exercise, those with stenoses exhibited a greater increase than those with complete occlusions, even though the resting pressure difference was equal.
在正常情况下，静息时以及运动一分钟后，踝部收缩压超过臂部收缩压，因此臂 - 踝压差为负。存在动脉阻塞时，该压差在静息时为正或运动后变为正值。为了确定其在特定病例中的值和适用性，已对几种压力测试方法进行了比较。平均而言，在跑步机测力计上进行100米运动所产生的压差增量相对于静息时的压差遵循以下方程：ΔP100m = 1.53ΔPR + 24.8 mmHg，r = 0.92。最大运动或200米运动后的增量以及标准化踮脚运动后的增量相当。闭塞后反应性充血产生的增量较小但仍显著。在跑步机上进行100米运动后对患者进行比较时，尽管静息压差相等，但有狭窄的患者比完全闭塞的患者增量更大。
