However, while the demonstration of a causal relationship between postural stability and the susceptibility to MS is still lacking, recent studies suggest that motion sick individuals have genuine deficits in selecting and reweighting multimodal sensory information. Here we investigate how the adaptation to changing postural situations develops and how the dynamics in multisensory integration is modulated on an individual basis along with MS susceptibility. We used a postural task in which participants stood on a posturographic platform with either eyes open (EO) or eyes closed (EC) during three minutes. The platform was static during the first minute (baseline phase), oscillated harmonically during the second minute (perturbation phase) and returned to its steady state for the third minute (return phase). Principal component (PC) analysis was applied to the sequence of short-term power density spectra of the antero-posterior position of the center of pressure. Results showed that the less motion-sick a participant is, the more similar is his balance between high and low frequencies for EO and EC conditions (as calculated from the eigenvector of the first PC). By fitting exponential decay models to the first PC score in the return phase, we estimated, for each participant in each condition, the sluggishness to return to the baseline spectrum. We showed that the de-adaptation following platform oscillation depends on the susceptibility to MS. These results suggest that non motion-sick participants finely adjust their spectrum in the perturbation phase (i.e. reweighting) and therefore take longer to return to their initial postural control particularly with eyes closed. Thus, people have idiosyncratic ways of doing sensory reweighting for postural control, these processes being tied to MS susceptibility.<\/jats:p>","DOI":"10.1371\/journal.pone.0260863","type":"journal-article","created":{"date-parts":[[2021,12,9]],"date-time":"2021-12-09T18:39:30Z","timestamp":1639075170000},"page":"e0260863","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":5,"title":["Idiosyncratic multisensory reweighting as the common cause for motion sickness susceptibility and adaptation to postural perturbation"],"prefix":"10.1371","volume":"16","author":[{"given":"Merrick","family":"Dida","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Corinne","family":"Cian","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pierre-Alain","family":"Barraud","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4267-6995","authenticated-orcid":true,"given":"Michel","family":"Guerraz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2180-9250","authenticated-orcid":true,"given":"Rafael","family":"Laboissi\u00e8re","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2021,12,9]]},"reference":[{"issue":"1","key":"pone.0260863.ref001","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1152\/physrev.1970.50.1.1","article-title":"Motion sickness.","volume":"50","author":"KE Money","year":"1970","journal-title":"Physiol Rev"},{"issue":"1","key":"pone.0260863.ref002","doi-asserted-by":"crossref","first-page":"21","DOI":"10.1016\/S0020-7373(69)80009-X","article-title":"Motion sickness\u2014some theoretical considerations.","volume":"1","author":"JT Reason","year":"1969","journal-title":"Int J Man-Mach Stud."},{"key":"pone.0260863.ref003","first-page":"123","volume-title":"The Accelerative Stimulus for Motion Sickness.
