“…Transcutaneous electrical nerve stimulation of the posterior neck and the right Zusanli acupoint was found to be effective in reducing simulator sickness symptoms and alleviating cognitive impairment . Recently, stroboscopic illumination at 8 herts, by ambient strobe light or by liquid crystal display shutter glasses, reduced the severity of MS symptoms and improved the performance on the vigilance task in soldiers exposed to a nauseogenic flight in a helicopter .…”

Motion sickness (MS) is a common physiological response to real or virtual motion. Numerous studies have investigated the neurobiological mechanism and the control measures of MS. This review summarizes the current knowledge about pathogenesis and pathophysiology, prediction, evaluation, and countermeasures of MS. The sensory conflict hypothesis is the most widely accepted theory for MS. Both the hippocampus and vestibular cortex might play a role in forming internal model. The pathophysiology focuses on the visceral afference, thermoregulation and MS-related neuroendocrine. Single-nucleotide polymorphisms (SNPs) in some genes and epigenetic modulation might contribute to MS susceptibility and habituation. Questionnaires, heart rate variability (HRV) and electrogastrogram (EGG) are useful for diagnosing and evaluating MS. We also list MS medications to guide clinical practice. Repeated real motion exposure and combined visual-vestibular interaction training accelerate the progress of habituation. Behavioral and dietary countermeasures, as well as physiotherapy, are also effective in alleviating MS symptoms.

“…peripheral accuracy), and provides an opportunity to examine eye-hand coordination (EHC) in relation to performance evaluation due to a paucity of research in this area. Research using stroboscopic exposure has been conducted into the prevention of air travel sickness [21], space motion sickness [22], and has been shown to be an effective countermeasure in these particular ecologically valid environmental settings.…”

Background Stroboscopic visual training (SVT) has been shown to improve cognitive skills and perceptual performance by carrying out events under situations of intermittent vision. Aims The aim of this study was to investigate whether an SVT training period could improve the eye-hand coordination (EHC) performance on a practiced task for a group of sports participants. Methods Sixty-two male participants were randomly assigned to either a strobe group (SG n = 31), or control group (CG n = 31). The method employed a Sport Vision Trainer™ 80 sensor pad to measure the mean speed of reaction time of participants extinguishing randomly illuminated lights on an electronic board. One trial consists of 20 lights. One week following pre-testing on the Sport Vision Trainer™ (4 × 6 trials), a pre-training baseline assessment of 1 × 6 trials was conducted to measure their abilities to complete the EHC task. Four × six trials (480 lights) were then completed in the training phase with the CG continuing to train with unimpaired vision, whilst the SG wore Nike Vapor Strobe ® (controlled rate of 100 ms visible to 150 ms opaque). Post-training assessments were administered immediately, 10 min and 10 days after SVT each consisting of six trials (120 lights). A visual search (VS) non-trained transfer test was also administered pre-SVT and after 10 days. This involved an e-prime programme using a laptop where participants had to identify a target stimulus located amongst distractor stimuli. Results Treatment effects were observed at each time point. Baseline performance was significantly related to retention performance immediately (p = .003), 10-min post (p = .001) and 10 days post-training (p = .002). No significant differences were found for the VS test. Conclusion An acute SVT exposure using stroboscopic goggles significantly improved EHC performance. Future research should explore these mechanisms further using different exposure, frequencies, and focused identification of training drills as a complementary intervention for individual or team sports.

“…Our observation also echoes an early investigation showing that predictive visual cues produced by displaying moving point prior to visual stimulus enhanced self-motion perception and relieved MS in immersive virtual environment (Fujita, 2004 ). Webb et al have reported that 8 Hz stroboscope illumination in cabin significantly reduced the incidence of nausea in helicopter passengers compared with non-stroboscope condition (Webb et al, 2013 ). The authors also claimed that the nausea scores were less under the 8 Hz setting than the 4 Hz setting which appears to reduce distorted vision-induced MS via transiently improving gaze stability (reduce retinal slip) during locomotion (Jones and Mandl, 1981 ; Bos and Bles, 2004 ; Han et al, 2005 ; Reschke et al, 2006 ; Webb et al, 2013 ; Muntaseer Mahfuz et al, 2018 ).…”

Motion sickness (MS) is caused by mismatch between conflicted motion perception produced by motion challenges and expected “internal model” of integrated motion sensory pattern formed under normal condition in the brain. Stroboscopic light could reduce MS nausea symptom via increasing fixation ability for gaze stabilization to reduce visuo-vestibular confliction triggered by distorted vision during locomotion. This study tried to clarify whether MS induced by passive motion could be alleviated by stroboscopic light with emitting rate and intensity synchronized to acceleration–deceleration phase of motion. We observed synchronized and unsynchronized stroboscopic light (SSL: 6 cycle/min; uSSL: 2, 4, and 8 cycle/min) on MS-related gastrointestinal symptoms (conditioned gaping and defecation responses), motor disorders (hypoactivity and balance disturbance), and central Fos protein expression in rats receiving Ferris wheel-like rotation (6 cycle/min). The effects of color temperature and peak light intensity were also examined. We found that SSL (6 cycle/min) significantly reduced rotation-induced conditioned gaping and defecation responses and alleviated rotation-induced decline in spontaneous locomotion activity and disruption in balance beam performance. The efficacy of SSL against MS behavioral responses was affected by peak light intensity but not color temperature. The uSSL (4 and 8 cycle/min) only released defecation but less efficiently than SSL, while uSSL (2 cycle/min) showed no beneficial effect in MS animals. SSL but not uSSL inhibited Fos protein expression in the caudal vestibular nucleus, the nucleus of solitary tract, the parabrachial nucleus, the central nucleus of amygdala, and the paraventricular nucleus of hypothalamus, while uSSL (4 and 8 cycle/min) only decreased Fos expression in the paraventricular nucleus of hypothalamus. These results suggested that stroboscopic light synchronized to motion pattern might alleviate MS gastrointestinal symptoms and motor disorders and inhibit vestibular-autonomic pathways. Our study supports the utilization of motion-synchronous stroboscopic light as a potential countermeasure against MS under abnormal motion condition in future.
