Traditionally, strain gauge technique is used in Denmark to measure ankle blood pressure, a method requiring both time and well-trained personnel. In a study involving 90 limbs in 45 patients, this method was compared with ultrasonic technique using a portable 5 MHz Doppler. The reproducibility of Doppler ankle pressure measurement was similar to that found in strain gauge based studies. Two consecutive measurements may differ by 20 mmHg or in terms of ankle-brachial index by 0.15 before this is considered significant. No systematic variation was found between the two methods. Increasing difficulties were encountered with the Doppler technique at pressures below 50 mmHg. It is concluded that Doppler is a good alternative to strain gauge for measurement of ankle blood pressure.
传统上，丹麦使用应变计技术来测量脚踝血压，该方法既耗时又需要训练有素的人员。在一项涉及45名患者90条肢体的研究中，将这种方法与使用便携式5兆赫多普勒的超声技术进行了比较。多普勒脚踝压力测量的可重复性与基于应变计的研究结果相似。在认为差异显著之前，连续两次测量的差异可能达到20毫米汞柱，或者脚踝臂指数差异达到0.15。两种方法之间未发现系统差异。在压力低于50毫米汞柱时，使用多普勒技术会遇到越来越多的困难。结论是，在测量脚踝血压方面，多普勒是应变计的一种很好的替代方法。
