The reliability of claudication pain and the metabolic and hemodynamic measurements of the lower limbs of patients with stable peripheral vascular occlusive disease (PVOD) were compared during and following single-stage (S) and progressive (P) treadmill tests. Ten patients (69.8 +/- 1.8 yr; X +/- SE) walked to maximal claudication pain twice a month for 4 months. Patients walked at 1.5 mph up a 7.5% grade (S test) and at 2 mph on a 0% grade, increasing by 2% every 2 min (P test). Distance walked to the onset of claudication pain (CPD) and maximal walking distance (MWD) were recorded. Foot transcutaneous oxygen tension (TcPO2) was measured before, during, and after exercise, while ankle systolic blood pressure (SBP) and the ankle-to-brachial SBP index (ABI) were measured before and after exercise. Intraclass correlation coefficients (R) of CPD and MWD during S tests were R = 0.53 and R = 0.55, respectively. In contrast, the respective R values during P tests were R = 0.89 and R = 0.93. Higher R values of foot TcPO2 were also obtained during and following P tests, while ankle SBP and ABI were highly reliable following both tests. It is concluded that the severity of PVOD is better assessed by P treadmill tests because clinical measurements are more reliable during exercise and recovery.
在单阶段（S）和渐进式（P）跑步机测试期间及之后，对稳定型外周血管闭塞性疾病（PVOD）患者的间歇性跛行疼痛以及下肢的代谢和血流动力学测量的可靠性进行了比较。10名患者（69.8±1.8岁；X±SE）每月两次走到最大间歇性跛行疼痛程度，持续4个月。患者以1.5英里/小时的速度在7.5%的坡度上行走（S测试），并以2英里/小时的速度在0%的坡度上行走，每2分钟增加2%（P测试）。记录走到间歇性跛行疼痛发作时的行走距离（CPD）和最大行走距离（MWD）。在运动前、运动期间和运动后测量足部经皮氧分压（TcPO2），同时在运动前和运动后测量踝部收缩压（SBP）和踝臂收缩压指数（ABI）。S测试期间CPD和MWD的组内相关系数（R）分别为R = 0.53和R = 0.55。相比之下，P测试期间相应的R值分别为R = 0.89和R = 0.93。在P测试期间及之后，足部TcPO2也获得了更高的R值，而在两种测试之后，踝部SBP和ABI都具有高度可靠性。得出的结论是，通过P跑步机测试能更好地评估PVOD的严重程度，因为在运动和恢复期间临床测量更可靠。
