In 30 patients with cervical dystonia in the posture of orthostasis, an obvious change of the electromyographic pattern was shown both at rest and in different functional tests. The analysis has shown an enhanced excitability of motoneurons and a disorder of the cortical control, as well as enhancement of the irradiation process between paired structures controlling activity of opposite muscular groups. After treatment with intratympanal administration of an ototoxical preparation on the opposite side in respect to head turn direction, normalising of the cortical control and diminishing of the excitation irradiation. The data obtained suggest a significant role of the vestibular otolithic apparatus in regulation of postural disorders in extrapyramidal pathology.
在30例处于直立姿势的颈部肌张力障碍患者中，无论是在休息时还是在不同功能测试中，肌电图模式都出现了明显变化。分析表明，运动神经元兴奋性增强、皮质控制紊乱，以及控制对侧肌肉群活动的配对结构之间的辐散过程增强。在向与头部转动方向相反的一侧鼓室内给予耳毒性制剂进行治疗后，皮质控制恢复正常，兴奋辐散减弱。所获得的数据表明，前庭耳石器官在锥体外系病变的姿势障碍调节中起重要作用。
