Effect of visual input on postural stability in young adults with chronic motion sensitivity: A controlled cross-sectional study

Abstract

The results suggest that young adults with CMS are over-reliant on visual cues for postural stability, and that visual dependence is not influenced by gender.

Sexual dimorphism in vestibular function and dysfunction

“…This result supports the hypothesis that their motion sickness susceptibility was at least partly hormone related (Golding et al 2005). Alharbi et al (2017) compared the responses of subjects who suffered from chronic motion sensitivity (CMS) and those that did not (non-CMS), to a computerized dynamic posturography task with immersion in virtual reality, in which they were exposed to optokinetic stimuli. Although they found a significant difference in postural sway between the CMS and non-CMS groups, they found no significant difference between men and women in either group.…”

“…Historically, it has been thought that motion sickness is more common in women than in men (Alharbi et al 2017; see Golding 2006 andKoch et al 2018 for reviews). Many studies have reported that women report motion sickness more frequently and experience more severe symptoms than men (Dobie et al 2001; Golding 2006; Kennedy et al 1995;Lawther and Griffin 1988).…”

Multi-Dimensional and Objective Assessment of Motion Sickness Susceptibility Based on Machine Learning

“…Temperature (TEMP) (11), skin conductance level (SCL) (12), electrogastrography (EGG) (13), and heart rate variability (14) obtained solely from body surface recordings have a long history as objective indicators for assessing MS susceptibility, and Gavgani et al found that SCL in the forehead was the best physiological correlate of VIMS-induced nausea symptoms (15). Objective assessments of MS susceptibility based on the results of vestibular function tests, such as the vestibulo-ocular reflex for different vestibular receptors (16)(17)(18), vestibular evoked myogenic potentials (19)(20)(21), and computerized dynamic posturography (22), are gradually becoming the focus of research, among them, the gain asymmetry of the video head impulse test, the nystagmus slowphase velocity evoked by the caloric test and the amplitude of the cervical vestibular evoked myogenic potential vary in groups of participants with different susceptibility to MS. Functional brain assessments, such as electroencephalogram (23,24), functional magnetic resonance imaging (25,26) and functional near-infrared spectroscopy (27,28), have facilitated the objective assessment of MS susceptibility at the level of higher nerve centers, meanwhile, the correlation between the intensity of activity in certain brain regions during MS exposure and the degree of MS discomfort have been confirmed by several studies. In addition, the levels of arginine vasopressin, ghrelin and immunoglobulins in blood after MS exposure have been found to correlate with the severity of MS (29,30), while the discovery of single-nucleotide polymorphism and chromosomes associated with MS susceptibility provides new alternatives for the assessment of MS susceptibility (31,32).…”

“…Concernant l'implication des différences individuelles dans l'utilisation de la modalité visuelle, les études sur les liens entre le facteur de dépendance visuelle pour le maintien de la posture et le genre ne sont pas toutes convergentes. Par exemple, l'étude d'Alharbi (Alharbi et al, 2017) se penchant sur les liens entre stabilité posturale, sensibilité aux indices visuels et mal des transports dans un dispositif de posturographie dynamique (Bertec's Computerized Dynamic Posturography CDP/IVR, système commercial pour la rééducation vestibulaire) dans lequel les informations visuelles sont soient couplées aux informations posturales et vestibulaires, soit conflictuelles, suggèrent que les adultes sensibles au mal des transports sont plus dépendants des informations visuelles pour maintenir la stabilité posturale, mais que la dépendance visuelle ne dépend pas du genre.…”
