The ankle-brachial pressure index (ABPI) responses to different exercise intensities on a treadmill were evaluated to clarify the relationship between intermittent claudication and the haemodynamics in the leg.
Thirty patients with intermittent claudication (32 symptomatic legs) due to peripheral arterial occlusive disease were exercised on a treadmill to determine their pain-free walking distance, maximum walking distance (MWD) and recovery time. Each subject was exercised at 25% and 50% of the MWD to determine the effect of work intensity on the drop in ABPI, and the recovery time.
In the claudicating legs, 25% of the MWD resulted in almost the same reduction in ABPI as 50% of the MWD, and the MWD. In contrast, the ABPI in the asymptomatic legs (13) was significantly decreased in proportion to the walking distance. The recovery time increased linearly in both the groups, as the walking distance increased.
The recovery time of the ABPI correlated well with the intensity of workload, while the drop in ABPI did not.
评估在跑步机上不同运动强度下的踝臂压力指数（ABPI）反应，以阐明间歇性跛行与腿部血流动力学之间的关系。
30例因外周动脉闭塞性疾病导致间歇性跛行的患者（32条有症状的腿）在跑步机上进行运动，以确定其无痛步行距离、最大步行距离（MWD）和恢复时间。每位受试者以MWD的25%和50%进行运动，以确定工作强度对ABPI下降及恢复时间的影响。
在出现跛行的腿部，MWD的25%导致的ABPI下降与MWD的50%及MWD本身导致的下降几乎相同。相比之下，无症状腿部（13条）的ABPI随步行距离的增加而显著降低。随着步行距离增加，两组的恢复时间均呈线性增加。
ABPI的恢复时间与工作量强度密切相关，而ABPI的下降则不然。
