Diagnostic method for the vibration syndrome with special reference to finger skin temperature and vibratory sense threshold
研究了34名链锯操作员和9名健康学生在10℃冷水刺激前后手指皮肤温度和振动感觉阈值的变化，发现刺激后5、10、15分钟的测量值能以90%以上准确率区分患者与健康人，推荐10℃冷刺激试验用于振动综合征筛查。
The skin temperature and vibratory sense threshold of 34 chain-saw operators, ten of whom were diagnosed as suffering from vibration syndrome, and nine healthy students were measured before and immediately, 5, 10, and 15 min after 10 min of cold provocation of the left hand in water at a temperature of 10℃. Scattergrams of these parameters at the five points in time were drawn, and a boundary line for discrimination between the study groups was obtained at each of the five points in time. With the use of the boundary line for 5, 10, or 15 min after the provocation, it was possible to discriminate between the patients and the other subjects with more than 90 % accuracy. Considering the severe pain caused by the conventional 5℃ cold provocation test, the 10℃ test can be recommended for the screening and diagnosis of vibration syndrome.
