[前言]作为振动疾病的诊断之一是测定振动感觉,但是振动病的诊断法,还处于基础研究阶段,尚未达到对振动病的实用诊断。首先把正常人由食指到小指的4个手指放到发振台面上并加压400克,以求得这时振动感觉阈值。在5赫芝以下时阈值降低,20—30赫芝时随频率的升高阈值有上升倾向。在这次观察的阈值为低频率和高频率,即5、30、100、200赫芝这4个频率方面阈值,季节性变动状态,并研究了和所测皮肤温之间的关系。
[Introduction] One of the diagnoses of vibrational diseases is the measurement of the sensation of vibration. However, the diagnosis of vibrational diseases is still at a basic research stage and has not yet reached a practical diagnosis of vibrational diseases. First of all, the normal from the index finger to the little finger 4 fingers on the vibration table and pressure 400 grams, in order to obtain the vibration sensation threshold. Threshold decreases below 5 Hertz, while 20-30 Hertz tends to increase with increasing frequency. Thresholds for this observation were thresholds for seasonal and low frequency and high frequency, ie, 4, 5, 10, 100, 200 Hz, and the relationship between the measured and the measured skin temperature.
