UNASSIGNED:在太空飞行(SF)期间前庭(耳石)功能受到高度抑制,对这些变化的研究对于SF任务期间空勤人员的安全非常重要。前庭功能(特别是,使用不同的方法研究了临床和空间医学中的耳石-眼反射-OOcR)。然而,不同的方法和方法会影响结果。
UNASSIGNED:当前的研究解决了通过不同方法获得的OOcR结果是否不同的问题,以及不同传入系统在OOcR调制中的作用。
UNASSIGNED:共有25名俄罗斯宇航员自愿参加了我们的研究。他们是国际空间站(ISS)长期太空任务的机组人员。宇航员在飞行前和飞行后的“感官适应”和“凝视旋转”实验中进行了检查,前两次(飞行前)和后三次(飞行后)。我们使用两种不同的视频眼图(VOG)系统来记录每个实验中获得的OOcR。
UNASSIGNED:两种VOG系统的比较未导致OOcR测量结果的显着和系统差异。静态扭转耳石-眼反射(OOR)的分析,静态扭转耳石-颈-眼反射(OCOR)和偏心离心(OOREC)期间的静态扭转耳石-眼反射表明,与OOR和OCOR(飞行前和飞行后后期)相比,OOREC导致较低的OOcR响应。然而,所有宇航员在飞行后早期的OOcR均显著下降.
UNASSIGNED:分析通过不同方法(OOR,OCOR,和OOREC)表明不同的传入系统(触觉-本体感觉,颈-颈,视觉和前庭传入输入)对OOcR有影响。
UNASSIGNED: The vestibular (otolith) function is highly suppressed during space flight (SF) and the study of these changes is very important for the safety of the space crew during SF missions. The vestibular function (particularly, otolith-ocular reflex-OOcR) in clinical and space medicine is studied using different methodologies. However, different methods and methodologies can influence the outcome results.
UNASSIGNED: The current study addresses the question of whether the OOcR results obtained by different methods are different, and what the role is of the different afferent systems in the modulation of the OOcR.
UNASSIGNED: A total of 25 Russian cosmonauts voluntarily took part in our study. They are crewmembers of long duration space missions on the International Space Station (ISS). Cosmonauts were examined in pre- and post-flight \"Sensory Adaptation\" and \"Gaze Spin\" experiments, twice before (preflight) and three times after SF (post-flight). We used two different video oculography (VOG) systems for the recording of the OOcR obtained in each experiment.
UNASSIGNED: Comparison of the two VOG systems didn\'t result into significant and systematic differences in the OOcR measurements. Analysis of the static torsion otolith-ocular reflex (OOR), static torsion otolith-cervical-ocular reflex (OCOR) and static torsion otolith-ocular reflex during eccentric centrifugation (OOREC) shows that the OOREC results in a lower OOcR response compared to the OOR and OCOR (before flight and late post-flight). However, all OOcRs were significantly decreased in all cosmonauts early post-flight.
UNASSIGNED: Analysis of the results of ocular counter rolling (OCR) obtained by different methods (OOR, OCOR, and OOREC) showed that different afferent systems (tactile-proprioception, neck-cervical, visual and vestibular afferent input) have an impact on the OOcR.
