Observations on wrist tremor have been made in the horizontal plane using a tremorograph of new design. A small tap to the hand gave rise to a decrementing series of oscillations at about 9 Hz; as these effects were seen in relaxed and in anaesthetised subjects they were not due to neural reflexes. With the fingers partially extended the spontaneous tremor increased markedly and taps again gave rise to a series of oscillations. Under these circumstances there was no modulation of the EMG. It is accordingly concluded that mechanical wrist resonance plays a major role in the forms of tremor studied.
使用一种新设计的震颤描记器在水平面观察手腕震颤。对手部的轻轻敲击会引发一系列频率约为9赫兹且逐渐衰减的振荡；由于在放松和麻醉的受试者中都观察到了这些效应，所以它们并非由神经反射引起。当手指部分伸展时，自发震颤明显增加，敲击再次引发一系列振荡。在这种情况下，肌电图没有调制现象。因此得出结论，机械性手腕共振在所研究的震颤形式中起主要作用。
