Parabolic Flight Induced Neuroplasticity Studied With Advanced Magnetic Resonance Imaging Methods
A study testing parabolic flight and MRI in people with Healthy, run by University Hospital, Caen at 1 site in France.
Trial summary
Weightlessness profoundly modifies many physiological systems and especially the nervous system and the vestibular system. The changes in the nervous system are based in part on brain plasticity mechanisms, that is to say on modifications of neurons and their connections. Read more about this study

About this study
Weightlessness profoundly modifies many physiological systems and especially the nervous system and the vestibular system. The changes in the nervous system are based in part on brain plasticity mechanisms, that is to say on modifications of neurons and their connections. They are the source of some of the behavioral response observed in the parabolic flight or in astronauts. For example, it is commonly observed that in the second and third days of parabolic flight campaigns with 3 flights, fewer participants are prone to motion sickness during the first day. Similarly, during their first trip into space, astronauts suffer 2/3 for 2 or 3 days of space sickness - special form of motion sickness - while this proportion is much lower in the second trip.
The hypothesis of this study is that short-term weightlessness as well as changes in the level of gravity experienced during parabolic flights, induce neuroplascity phenomena in brain regions involved in the integration of vestibular, visual and proprioceptive.

The goal is to objectify these plasticity phenomena, and assess their changes over time, using methods of Magnetic Resonance Imaging (MRI). A standard MRI will give an anatomical image of the brain. For this study, a variant called diffusion MRI (Diffusion Tensor Imaging - DTI) will visualize nerve bundles and their journey in the brain. The total duration of this review will be about ¾ hour.
The results of this study will be compared with those of an ongoing study of 12 astronauts who have the same MRI scans taken before and after a trip to the International Space Station. Investigators can then evaluate the effect of duration of exposure to weightlessness on the phenomena of neuroplasticity.

Clinical summary

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 6 Aug 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
biomarkers of neuroplasticity with MRI (time frame: change over baseline and 6 months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Aug 2015.
