[Ocular counterrolling as an indicator of vestibular otolith function].
Space Motion Sickness (SMS) occurred in the first few days of space flight correlated with the vestibular function. As the main influence of weightlessness in space focused on the otolith receptors. The test of otolith function is of great importance. Although there are a lot of methods to test otolith function, at present ocular counterrolling is the only relative pure indicator of otolith function. It provide a valid method for predicting SMS susceptibility, it has great application prospect in the research of the SMS mechanism and the readaptability of vestibular function after space flight, it also provides great reference in the clinical diagnosis of vestibular problems.
