采用惯性加载法研究生理性和原发性手颤；手加速度和前臂肌电数据进行自动和交叉光谱分析。早期特发性震颤与生理性震颤的8 ~ 12hz分量在性质上相似，提示该震颤分量是特发性震颤的一种形式。晚期特发性震颤的频率为4至8赫兹。在10个家庭中观察到震颤频率在两个范围内的患者。在对抗性前臂肌肉中，44例患者中有11例观察到同步和交替震颤爆发。特发性震颤不应该仅仅根据频率或肌电图来分类。
We studied physiologic and essential hand tremor using inertial loading; hand acceleration and forearm EMG data were analyzed by auto- and cross-spectral analysis. Early essential tremor was qualitatively similar to the 8- to 12-Hz component of physiologic tremor, suggesting that this tremor component is a forme fruste of essential tremor. Advanced essential tremor had a frequency of 4 to 8 Hz. Patients with tremor frequencies in both ranges were observed in each of 10 families. In antagonistic forearm muscles, both synchronous and alternating tremor bursts were observed in 11 of 44 patients. Essential tremor should not be classified solely on the basis of frequency or EMG pattern.
