A cold provocation test (measurement of finger systolic pressure during combined body and local finger cooling) was performed on 111 male patients exposed to vibration and with a typical history of cold induced white finger. A new method of calculating the test result is described--namely, digital systolic blood pressure in the cooled test finger as a percentage of the systolic pressure in the arm (DP%). The conventional way of calculating the result, the systolic pressure in the cooled test finger as a percentage of the systolic pressure in the test finger when heated to 30 degrees C, corrected for changes in systemic pressure by the use of a reference finger (FSP%), requires the measurement of the systolic pressure in a reference finger. The two ways of calculating the test results give a similar sensitivity (74% for FSP%, 79% for DP% if all histories are regarded as true) but the new method does not require pressure measurements in a reference finger. This makes the test easier to perform and the result easier to understand.
对111名接触振动且有典型冷诱发白指病史的男性患者进行了冷激发试验（在全身及手指局部冷却过程中测量手指收缩压）。本文描述了一种计算试验结果的新方法——即，冷却试验手指的数字收缩压占手臂收缩压的百分比（DP%）。传统的计算结果方法是，冷却试验手指的收缩压占加热至30摄氏度时试验手指收缩压的百分比，并通过使用参考手指校正全身压力变化（FSP%），这种方法需要测量参考手指的收缩压。两种计算试验结果的方法具有相似的敏感性（FSP%为74%，若将所有病史视为真实情况，DP%为79%），但新方法不需要测量参考手指的压力。这使得该试验更易于进行，结果也更易于理解。
