Muscular vibrations were recorded from different relaxed and contracted skeletal muscles in human subjects, with the use of a piezo-electric device. Simultaneous wire-EMG recordings were performed. Spectral analysis of the acceleration curves (vibromyograms) disclosed muscle and function dependent compound frequency patterns. We suggest that the activity of motor units including the action of central reflex loops and oscillatory driving is mainly responsible for the muscular vibrations. Other sources are discussed. Computer-Vibromyography as a mechanical ensemble measurement supplements bioelectric EMG techniques and classical tremor analysis and provides further insights into the function of muscle and motor-system.
使用压电装置记录了人体受试者不同放松和收缩状态下的骨骼肌振动情况。同时进行了有线肌电图记录。对加速度曲线（振动肌电图）的频谱分析揭示了肌肉和功能相关的复合频率模式。我们认为，包括中枢反射环路作用和振荡驱动在内的运动单位活动是肌肉振动的主要原因。还讨论了其他来源。计算机振动肌电图作为一种机械整体测量方法，补充了生物电肌电图技术和经典震颤分析，并为肌肉和运动系统的功能提供了进一步的见解。
