Motion Sickness on Astrolabe's Vessel

Study Overview
=================
Brief Summary
-----------------
Sea sickness syndrome is present for 80% of persons on board when the boat rotation missions Astrolabe, sometimes there is a risk of very significant dehydration. A special unit specialized in the fundamental study of the vestibular system (inner ear), sensory organ at the base of visual-vestibular conflict inducing this syndrome, also provides medical support for parabolic flights (flight reproducing weightlessness) where this syndrome is strongly present. The goal of the study is to assess the frequency of occurrence of this sea sickness syndrome on the Astrolabe, to understand the triggers (type of boat movements, personality traits, anxiety / stress) without changing habits on board for those on board taking a antinaupathique treatment given by the ship's doctor. This study will be done in collaboration between INSERM U 1075 (France) and the Laboratory of military research VIPER specialized in extreme environments (Belgium). The ultimate goal will be to provide the best recommendations and the best treatment regimen to alleviate as best as possible the symptoms of people on board of the Astrolabe so scientists on board can perform their work.

Detailed Description
-----------------
Background: The objectives were to assess the prevalence, severity, medication taken and to look for predictive factors, in order to better identify characteristics of passengers at risk of motion sickness during transport scientists travelling from Hobart in Tasmania to the French polar stations in Antarctica. Methods: Two hundred and thirty-nine passengers were surveyed over 4 years with 4 round trips per year using Motion Sickness Susceptibility Questionnaire (MSSQ), Simulator Sickness Questionnaire (SSQ), state-trait anxiety test (STAI-Trait and STAI-State), and general parameters (age, gender, number of trips, jet-lag, direction of the trip), medication, calculation of the distance of each passenger's cabin to the Centre of Gravity (CoG.).
