Combination of Intranasal Scopolamine and Sensory Augmentation to Mitigate G-transition Induced Motion Sickness and Enhance Sensorimotor Performance

Study Summary

The primary specific aim of this Field Test aim is to evaluate the feasibility and efficacy of administering the intranasal scopolamine gel in operational field settings using both astronaut and ground-control subjects that are exposed to provocative motion as part of their assigned duties. For the ground-control subjects, these may include motion simulations (e.g., centrifuge), parabolic flights and/or Orion capsule recovery operations. Astronaut participants may choose to test Inscop during provocative preflight training exercises (e.g., centrifugation), and can choose to take the medication prophylactically to prevent symptoms or after symptom onset to treat motion sickness during the launch and/or landing mission phases. Both ground-control and astronaut participants will be required to test the medication during a training session to monitor for adverse side effects. Participants in the field test aim will complete short debrief questionnaires to capture motion sickness symptoms, side effects, and feasibility comments. The investigators will also include field "control" subjects who did not take (INSCOP) to comment on what countermeasures subjects used and their effectiveness. The investigators will be recruiting astronaut participants from free-flier missions (e.g., SpaceX Polaris Dawn), Private Astronaut Missions (e.g., Axiom), and standard missions to the International Space Station.

Primary Outcome

The maximum nausea score (from 0 = none to 3 = severe) will be recorded once for each of the first three inflight days and once for each of the first three postflight days, or once per operational setting not involving spaceflight (e.g., once per simulation or parabolic flight).
