Studies on the Correlation between Vestibular Function test and Autonomic Nervous System

When we use rotation for vestibular function test, we must aware that its response is largely changeable or modifiable according to the state of the subjects' autonomic nervous system, even if they are in good health, Especially, the majority of the unstable persons were labile in their parasympathetic factors. the duration of post-rotatory nystagmus is only served as a reference for labyrinthine function, when the subjects' autonomic nervous system is stable and weak stimulation is applied.
