本仪器是一种由128Hz机械振动转换成相应频率的电振荡,经功放后再转换成机械能的装置。依据振动力与振荡电压值之间的回归关系,确定振动觉的大小。文中介绍了本仪器的制作要点。仪器经临床使用证明,对神经系统疾病的早期诊断有一定的意义。
The instrument is a mechanical vibration by 128Hz converted to the corresponding frequency of electrical oscillation, after power amplifier and then converted into mechanical energy device. According to the vibration force and the relationship between the value of the oscillation voltage to determine the size of vibration perception. This article describes the production of the instrument points. The instrument proved by clinical use, has certain significance to early diagnosis of nervous system diseases.
