The fall in ankle systolic pressure after exercise serves as an objective indicator of the severity of haemodynamically important peripheral arterial disease. Twenty-six patients were studied to establish the effects of different work loads on the pressure response and to develop a test to standardise these effects. The patients walked for one or two minutes at 4 km/h and one or two minutes at 6 km/h, and the fall in pressure was the same when measured immediately after exercise. The time taken for the pressure to return to the pre-exercise value varied. As the fall in pressure occurs after only one minute of exercise at 4 km/h on a 10% slope, this might be adopted as a standard test. It is acceptable to the patient, since claudication, angina, and shortness of breath rarely occur. It is sensitive enough to detect mild or asymptomatic disease and is useful in following up patients.
运动后踝部收缩压的下降是血流动力学上重要的外周动脉疾病严重程度的客观指标。对26名患者进行了研究，以确定不同工作量对压力反应的影响，并开发一种测试来规范这些影响。患者以4公里/小时的速度行走1或2分钟，以6公里/小时的速度行走1或2分钟，运动后立即测量时压力下降情况相同。压力恢复到运动前值所需的时间各不相同。由于在10%坡度上以4公里/小时的速度运动仅1分钟后就会出现压力下降，这可能被用作标准测试。患者可以接受，因为很少出现跛行、心绞痛和呼吸急促。它足够灵敏以检测轻度或无症状疾病，并且在对患者进行随访时很有用。
