This paper establishes a standard method for measuring human tremor. The electronic instrument described is an application of this method. It solves the need for an effective and simple tremor-measuring instrument fit for wide distribution. This instrument consists of a piezoelectric accelerometer connected to an electronic circuit and to an LCD display. The signal is also analysed by a computer after accelerometer analogic/digital conversion in order to test the method. The tremor of 1079 healthy subjects was studied. Spectral analysis showed frequency peaks between 5.85 and 8.80 Hz. Chronic cigarette-smoking and coffee drinking did not modify the tremor as compared with controls. Relaxation session decreased tremor significantly in healthy subjects (P less than 0.01). This new tremor-measuring method opens new horizons in the understanding of physiological and pathological tremor, stress, anxiety and in the means to avoid or compensate them.
本文建立了一种测量人体震颤的标准方法。所描述的电子仪器是该方法的一种应用。它满足了对一种有效且简单、适合广泛应用的震颤测量仪器的需求。该仪器由一个连接到电子电路和液晶显示器的压电加速度计组成。在加速度计进行模拟/数字转换后，信号还会由计算机进行分析，以测试该方法。对1079名健康受试者的震颤进行了研究。频谱分析显示频率峰值在5.85至8.80赫兹之间。与对照组相比，长期吸烟和喝咖啡并未改变震颤情况。放松环节可使健康受试者的震颤显著降低（P<0.01）。这种新的震颤测量方法为理解生理性和病理性震颤、压力、焦虑以及避免或补偿它们的方法开辟了新的视野。
