踝臂指数被广泛认为是诊断和量化外周动脉疾病的关键工具。然而，它受到与其耗时性质和使用黄金标准多普勒超声方法进行测量所需技能有关的问题的困扰。踝臂指数自动测量装置旨在解决这些问题；本研究旨在将这种装置的性能与多普勒法进行比较。380名有心血管疾病危险因素的受试者(平均年龄：，男性57%)，首先用体积描记仪测量踝臂指数，然后用多普勒法测量。两种方法的平均差值为0.016+/-0.1，95%的符合度为+/-0.2。检测外周动脉疾病的敏感性，如多普勒踝臂指数所定义的
The ankle-brachial index is widely regarded as a pivotal tool for the diagnosis and quantification of peripheral arterial disease. It is, however, plagued by issues relating to its time consuming nature and the skills required to undertake its measurement using the gold standard Doppler ultrasound method. Automated ankle-brachial index measurement devices aim to address such issues; this study aimed to compare the performance of such a device with the Doppler method. Three hundred and eighty participants, with risk factors for cardiovascular disease (mean age: 64, 57% male), underwent ankle-brachial index measurement firstly with a plethysmographic device followed by the Doppler method. The mean difference between the two methods was 0.016+/-0.1, 95% limits of agreement: +/-0.2. Sensitivity for detection of peripheral arterial disease, as defined by Doppler ankle-brachial index
