利用计算机控制的转矩电机和机械臂，对10例成人对照和22例特发性震颤患者的手腕施加50 ms转矩脉冲和70秒二元伪随机转矩扰动，研究机械诱发的伸展反射振荡与特发性震颤的相互作用。通过对手腕施加惯性和弹簧载荷来分离这两种振荡。没有证据表明特发性震颤患者的拉伸反射活动增加或不稳定，并且拉伸反射潜伏期与特发性震颤的频率无关。特发性震颤和机械诱发的拉伸反射振荡是能够复杂相互作用的独立现象。
Using a computer-controlled torque motor and manipulandum, 50 ms torque pulses and 70 second trains of binary pseudorandom torque disturbances were applied to the wrists of 10 adult controls and 22 patients with essential tremor in order to study the interaction between mechanically-induced stretch-reflex oscillations and essential tremor. These two oscillations were separated by applying inertia and spring loads to the wrist. There was no evidence of increased or unstable stretch-reflex activity in the essential tremor patients, and stretch-reflex latencies did not correlate with the frequency of essential tremor. Essential tremor and mechanically-induced stretch-reflex oscillations are separate phenomena capable of complex interaction.
