单侧前庭毁损引起的中枢平衡代偿

Central balance compensation induced by unilateral vestibular destruction

单侧前庭毁损引起的平衡功能失调导致一系列参与平衡感知和调控的中枢神经核团都会发生相应的代偿性改变。这些参与维持平衡的中枢代偿性调节包括健侧前庭核与患侧前庭核之间的活动协调,视觉动眼系统的代偿性调节、小脑的代偿性改变、网状结构的信号协调,下橄榄核的代偿性调节、丘脑的代偿性丘觉、大脑皮层的平衡调控以及某些适应性行为的改变等。因此,单侧前庭毁损引起的中枢平衡代偿实际上是包含所有参与平衡感知调控的中枢神经核团来协同完成一个综合代偿性调节的复杂过程。

The balance dysfunction caused by unilateral vestibular destruction leads to corresponding compensatory changes in a series of central nerve nuclei involved in balance perception and regulation.The balance compensation includes the coordination of activities between the contralateral vestibular nucleus and the affected vestibular nucleus,the compensatory regulation of the visual eye movement system,the compensatory changes of the cerebellum,the signal coordination of the brainstem reticular formation,the compensatory regulation of the inferior olive nucleus,compensatory thalamus sensation,the balance regulation of the cerebral cortex,and certain adaptive behavior changes,etc.Therefore,central balance compensations induced by unilateral vestibular destruction are related to all central nerve nuclei involved in the regulation of balance perception,which coordinate to complete a complex process of comprehensive compensatory regulation.
