Cold-stress tests are used for evaluating vascular disorders in the hand-arm vibration syndrome, and the value of such tests based on finger skin temperature measurement has been investigated. However, there is a wide difference in the test conditions among countries and researchers. Standardization of the cold-stress tests is currently under discussion within the International Organization for Standardization. We reviewed various aspects of the cold-stress tests involving finger skin temperature measurement, including water temperature, hand immersion time and other test conditions, and evaluated their diagnostic significance. Water temperature varied from 0 degrees C to 15 degrees C and hand immersion time varied from 0.5 min to 20 min. The cold-stress tests are associated with relatively severe suffering, thus, higher temperature of cold water and shorter time of immersion are desirable. To date, however, there has not been sufficient data indicating diagnostic value in a test method involving cold water at around 15 degrees C. Diagnostic value is also influenced by other test conditions, such as room temperature, season, use of ischemia during immersion. For standardization of the cold-stress test involving finger skin temperature measurement, these factors must be considered together with water temperature and immersion time.
冷应激试验用于评估手臂振动综合征中的血管疾病，并且基于手指皮肤温度测量的此类试验的价值已得到研究。然而，各国和研究人员之间的试验条件存在很大差异。国际标准化组织目前正在讨论冷应激试验的标准化问题。我们回顾了涉及手指皮肤温度测量的冷应激试验的各个方面，包括水温、手部浸泡时间和其他试验条件，并评估了它们的诊断意义。水温从0摄氏度到15摄氏度不等，手部浸泡时间从0.5分钟到20分钟不等。冷应激试验会带来相对严重的不适，因此，希望使用温度较高的冷水和较短的浸泡时间。然而，迄今为止，尚无足够的数据表明在涉及约15摄氏度冷水的试验方法中具有诊断价值。诊断价值还受其他试验条件的影响，如室温、季节、浸泡期间是否使用缺血。对于涉及手指皮肤温度测量的冷应激试验的标准化，必须将这些因素与水温和浸泡时间一起考虑。
