Study of fusion tests for diagnosing hand-arm vibration syndrome -finger blood pressures during cold exposure and somatosensory evoked responses to electrical stimulation of skin-

为了诊断手臂振动综合征，作者调查了手指血压在一只手浸泡在冷水和体感诱发反应的皮肤电刺激，4例振动综合征患者雷诺现象和振动综合征患者没有雷诺现象进行了手指血压的测量，以及循环功能测试，在日本传统的。5名健康受试者测量了电刺激皮肤和正中神经的体感诱发反应，手指血压与皮肤温度、指甲按压试验和体积描记器的结果相关良好。有雷诺现象者与无雷诺现象者在浸泡试验时的指压差异大于常规试验，电刺激皮肤的体感诱发反应与针刺机械刺激的体感诱发反应非常相似，而与电刺激正中神经的体感诱发反应不相似。因此，我们的结论是，我们的新方法是有用的，方便检测振动综合征患者的手机械感受器的障碍。

For the purpose of diagnosing hand-arm vibration syndrome, authors investigated finger blood pressures during immersion of one hand in cold water and somatosensory evoked responses to electrical stimulation of the skin.Four vibration syndrome patients with Raynaud's phenomenon and for vibration syndrome patients without Raynaud's phenomenon were subjected to measurement of finger blood pressure as well as circulatory function tests used conventionally in Japan. Five healthy subjects were measured somatosensory evoed responses to electrical stimulation of the skin and of the median nerve.Finger blood pressure correlated well with findings of skin temperature, the nail press test and plethysmograph. The difference of finger blood pressures during immersion test between the patients with Raynaud's phenomenon and the patients without it was larger than those of the conventional tests.Somatosensory evoked responses to electrical stimulation of the skin were very similar to those to mechanical stimulation by pin-prick but not to electrical stimulation of the median nerve. Therefore, we concluded that our new method is useful and convenient for detecting disorder of mechanoreceptors of hands in vibration syndrome patients.
