“…As a matter of fact, previous studies have pointed out that, when the vestibular system is challenged, maintaining the same balance and posture starts to be cognitively demanding [1,2,66]. However, on the other hand, the incorporation of vestibular stimulation, like swinging on a swing during leisure time, as suggested in [67], over time could instead improve cognitive function. Although plausible, the link between vigilance and the vestibular system is far from being resolved by the present study.…”

Vigilance refers to the capability of humans to respond accordingly to relevant and unpredictable tasks and surrounding environment changes over prolonged periods of time. Identifying vigilance decrements can, therefore, have huge and vital impacts on several operational environments in which a simple slip of mind or a deficit in attention can bear life-threatening and disastrous consequences. Several methodologies have been proposed to assess and characterize vigilance, and the results have indicated that the sole measure of performance and self-reports are not enough to obtain reliable and real-time vigilance measure. Nowadays, monitoring head and body movements to obtain information about performance in daily activities, health conditions, and mental states has become very simple and cheap due to the miniaturization of inertial measurement units and their widespread integration into common electronic devices (e.g., smart glasses, smartwatches). The present study aimed to understand the relationship between head micromovements and body posture changes to vigilance decrease while performing the psychomotor vigilance task. The results highlighted that head micromovements can be employed to track vigilance decrement during prolonged periods of time and discriminate between conditions of high or low vigilance.

“…Враховуючи розгалужену мережу між вестибулярною та лімбічною системою, автори припускають, що методи вестибулярної стимуляції можуть впливати на емоції, стрес та когнітивні функції [24,25]. Однак типи вестибулярної стимуляції по-різному впливають на лімбічну систему, що проявляється покращенням або погіршенням настрою обстежуваних [26].…”

The main importance of the vestibular system is to maintain the vertical position of a person and ensure the coordination of movements. The peculiarity of the structure of the vestibular apparatus prompts it to be constantly in a state of spontaneous activity. This is due to the effect on it of afferent impulses that come from the labyrinths to the vestibular centers. With proper excitability, this information indicates the normal course of physiological reactions. In this regard, persons with normal vestibular sensitivity have not experience symptoms of impaired vestibular function. However, in cases where this spontaneous impulse changes due to the influence of external and internal factors, and the inhibition mechanisms are not sufficiently activated, symptoms appear that indicate the insufficiency of vestibular afferentation compensation processes and are manifestations of increased excitability of the vestibular analyzer. It is known from literary sources that increased sensitivity of the vestibular analyzer is widespread among the population. At the same time, there is a tendency to increase the prevalence of increased sensitivity of the vestibular analyzer among people of different ages. The review presents modern views on the peculiarities of the functional activity of the vestibular analyzer in different age periods. We are describe features of development, structure and reflex activity to ensure the vital activity of the organism from the beginning of intrauterine development to old age. We considered functions of ensuring a sense of position and movement of the body in space, maintaining both a posture at rest and during movement in different age periods. We also analyzed data on the frequency of symptoms of a vestibular analyzer disorder.

Objectives This retrospective, open-label study was undertaken to assess the safety of repeated, long-term electrical vestibular nerve stimulation (VeNS). The primary outcome for this study was assessment of hearing function as reported by formal audiometry testing. Methods Assessments were conducted on n=25 long-term users of daily 1.5 mA VeNS. Skin inspection of the mastoid area, otoscope examination of the inner ear, and formal audiometry testing was conducted on n=18 users. All participants completed a survey-based assessment to determine usage of the device, adverse events, and long-term outcomes. Results Mean duration of use was 22 months, with approximately 80% of users reporting 1 h of daily, or 1 h of regular (2–3 times per week) VeNS usage. No adverse events were reported. There were no significant findings during examination of the mastoid areas, ear canal, or tympanic membranes. There were no significant findings reported from the formal audiogram assessments. Conclusions This appears to be the first study to provide formal assessment to show that repeated, long-term VeNS usage has not generated any significant side effects or adverse events. Results from this study further support previous literature that electrical vestibular stimulation is both safe and well-tolerated.
