Altered Venous Function during Long-Duration Spaceflights
Aims: Venous adaptation to microgravity, associated with cardiovascular deconditioning, may contribute to orthostatic intolerance following spaceflight. The aim of this study was to analyze the main parameters of venous hemodynamics with long-duration spaceflight. Methods: Venous plethysmography was performed on 24 cosmonauts before, during, and after spaceflights aboard the International Space...
متن کاملOrientation illusions in spaceflight.
Investigations of spontaneous illusory reactions were carried out during space-flights of various durations by ANKETA questionnaires (104 cosmonauts). From a total of 104 cosmonauts, 24, in addition, used a dictaphone to record a verbal description of the illusions and their sensations on tape. Analysis of data generated by ANKETA and the tapes thus recorded have shown that during adaptation to...
متن کاملLong-term exposure to microgravity impairs vestibulo-cardiovascular reflex
The vestibular system is known to have an important role in controlling blood pressure upon posture transition (vestibulo-cardiovascular reflex, VCR). However, under a different gravitational environment, the sensitivity of the vestibular system may be altered. Thus, the VCR may become less sensitive after spaceflight because of orthostatic intolerance potentially induced by long-term exposure ...
متن کاملThe Challenge of Vestibular Rehabilitation in a Patient with Bilateral Vestibular Dysfunction Following Surgery: A Case Report
Introduction: Bilateral vestibular dysfunction (BVD) is an uncommon finding in vestibular assessment, and the combination of BVD and orthopedic problems represents a rare and challenging case for treatment. Case Report: The patient had several previous back surgeries and received gentamycin after surgery. After 6 months, she experienced continuous dizziness, unsteadiness and oscillopsia. ...
متن کاملDecreased otolith-mediated vestibular response in 25 astronauts induced by long-duration spaceflight.
The information coming from the vestibular otolith organs is important for the brain when reflexively making appropriate visual and spinal corrections to maintain balance. Symptoms related to failed balance control and navigation are commonly observed in astronauts returning from space. To investigate the effect of microgravity exposure on the otoliths, we studied the otolith-mediated responses...
