The provocation test with cold air in which only tested finger was exposed to 5ﾟC air has been developed by I.Tanaka, N.Inoue et al.for the assessment of vibration disease.Cold water immersion test was commonly used for diagnosing Raynaud phenomenon in hand-arm vibration syndrome and Raynaud syndrome. In this study, the validity of this provocation test with cold air was investigated as a substitute for the cold water immersion test. Subjects were 55 healthy women volunteers in their twenties with no history of peripheral circulation disease. The fingers of women in the laboratory at 23ﾟC were exposed to 5ﾟC air for 20 minutes using the provocation apparatus. Reactive parameters of finger tip skin temperature used in cold water immersion test, such as TFR and TTR,could be applied in a provocation test with cold air. Four reaction types of finger tip skin temperature curves were obtained during fingers local cooling with cold air. Most of the cases showed that the temperature fell at a certain level but thereafter began to rise. The other types observed include : temperature not falling more than the thermal resistance, temperature falling down after few thermal resistance, temperature falling down and re-rising slightly during finger cooling. These reaction types with cold air were affected by the time of food intake, experimental time, menstrual cycle, and seasonal conditions. The reactions of the finger tip skin temperature with glove were classified into resistance type, border type, and follow type, irrespective of the above mentioned four response types without glove. This indicates that the reactions of finger tip skin temperature with gloves were affected by some additional factors.

I.Tanaka，N.Inoue等人开发了仅通过测试手指暴露于5°C空气的冷空气的挑衅测试，用于评估振动疾病。Cold Water Immersion测试用于手柄振动综合征和Raynaud综合征中的诊断雷诺现象。在这项研究中，研究了与冷空气的挑衅测试的有效性，以替代冷水浸入测试。受试者是二十多岁的55名健康女性志愿者，没有外周循环疾病史。使用挑衅设备将实验室中妇女的手指暴露于5 c c空气20分钟。冷水浸入测试中使用的指尖皮肤温度的反应性参数，例如TFR和TTR，可以在冷空气的挑衅测试中应用。在手指局部冷却时，获得了四种反应类型的指尖皮肤温度曲线。大多数情况表明，温度在一定水平上下降，但此后开始升高。观察到的其他类型包括：温度不超过热电阻，几乎没有热电阻后温度下降，温度下降并在手指冷却过程中稍微升高。这些与冷空气的反应类型受食物摄入，实验时间，月经周期和季节性状况的影响。手指尖头温度与手套的反应分为电阻类型，边界类型，并遵循类型，无论上述四种无手套的响应类型如何。这表明手指尖皮温度与手套的反应受到其他因素的影响。
