Abstract
This paper presents the results from testing the vestibular function on return from repeated space flights (SF) in 32 cosmonauts of the International Space Station that were in long SFs of 125–215 days. The cosmonauts were tested twice before the flight (baseline data collection) and on days 1–2, 4–5, and 8–9 after landing. The testing was made using two methods for recording eye movements (with simultaneous recording of head movements): electro-oculography and video-oculography. It is shown that the repeated stay in the long SF leads to a considerable statistically significant reduction in the de-adaptation period. Atypical vestibular disorders and changed patterns of the otolith-semicircular canal interaction are observed mostly in the cosmonauts who have made their maiden flights to microgravity.
