Motion Sickness/Travel Sickness/Car Sickness
Published in Charles Theisler, Adjuvant Medical Care, 2023
Motion sickness is a common problem for people travelling by boat, car, train, or airplane. It is the sick feeling one gets when in motion but not in control of that motion (e.g., on an amusement park ride or as a passenger on a long car ride). The feeling builds from uneasiness to nausea, dizziness, possibly sweating, and vomiting. A headache may ensue for migraine sufferers.

Excessive stimulation of the labyrinthine receptors of the inner ear produces motion sickness with its symptoms of nausea, vomiting, pallor (paleness), and cold sweats. Vestibular disorders also result from drug toxicity, blood dyscrasias (hemorrhage into the labyrinth), and lesions of the eighth cranial nerve.

Afferents from the vestibular apparatus play an indispensable role in the development of motion sickness. Even though the underlying mechanism is not fully understood, the most popular theory suggests that motion sickness develops due to a sensory mismatch involving the vestibular, visual, and proprioceptive systems (i.e., those responsible for spatial orientation). When sensory feedback from one of these systems is not congruent with another and with the input expected on the basis of past experience, the nausea and vomiting of motion sickness are triggered.20,45

A driving simulator provides physical surrounding similar to an actual car with the help of control mechanisms and sound systems to stimulate the sense of driving experience. Nevertheless, the use of driving simulator is observed to be limited due to the adverse effect of simulator sickness. Simulator sickness is a condition analogous to motion sickness which is often experienced as a side effect during and after exposure to various virtual reality environments (Dużmańska et al., 2018; Lucas et al., 2020). Motion sickness is a sensation of wooziness often caused due to the perception of physical and visual motions (Heitz, 2018; Lucas et al., 2020). Drivers driving the simulator are in an illusion of self-motion where they experience movement due to simulation, but, in fact, are stationary. This effect is known as vection which produces an illusion of moving ahead (Almallah et al., 2021). The intensity of vection depends on the horizontal field of view. The horizontal field of view greater than 30 degrees results in a greater perception of self-motion (Stoner et al., 2011). However, a wide field of view is required in a driving simulator to display the right side and left side of the road for negotiating the driving scenario.

Participants in both conditions reported few adverse reactions and endorsed minimal experiences of motion sickness (M = 1.33 in the VR environment versus M = 2.50 in the 360° video virtual environment using a scale of 0-10). However, there were large individual differences related to the experience of motion sickness in both conditions (range = 0-6.5 and SD = 2.44 in the VR environment versus range = 1-6 and SD = 2.18 in the 360° video virtual environment). Participants who endorsed higher levels of motion sickness described symptoms of nausea, perspiration, and dizziness. In the virtual reality environment, individuals who experienced motion sickness noted that going around corners in the environment and instances where the visual experience did not match the participants’ kinesthetic movements (e.g., when the participant moved their head and the image didn’t change as quickly). In contrast, participants in the 360° video virtual environment noted that their motion sickness was associated with instances when “you’re moving and the image is bouncing a bit more” and that the experience was worst “at the very beginning, until I got oriented to how things were moving”.
Managing limb pain using virtual reality: a systematic review of clinical and experimental studies

The two randomised controlled trials found no significant difference pre–post intervention nor between intervention and control groups for pain intensity (Table 1). All eight pretest–posttest studies without a control found that the intervention alleviated pain with the mean decrease in pain intensity post intervention relative to baseline between 64 [17] and 32% [21] (Table 2). In the case series, responses to the interventions were varied and included complete resolution of pain to worsening pain. There were seven reports of case series with 28 patients and one report of a single case (i.e., a total of 29 patients). Of these 29 patients, nine experienced more pain during the intervention or within a few hours after intervention, although in several of these cases pain was gradually reduced with the repetition of sessions. It was stated that patients did not experience adverse reactions from the intervention in one study report [27]. In one case series, it was reported that one patient experienced motion sickness (i.e., dizziness and nausea) [25]. There was no mention of adverse reactions in any of the other reports.
