objective: The Video Head Impulse Test (V-HIT) is an easy-to-use, objective test that allows the evaluation of the six semicircular canals (CSC) and the visualization of the saccades that occur during the vestibulo-ocular reflex (VOR) testing. The aim of the study was to compare V-HIT data obtained from healthy individuals between the ages of 18 and 30 and to establish VOR normative data based on equally distributed gender group. Method: A hundred and thirty healthy people (65F-65E) between the ages of 18 and 30 got the V-HIT. The head was turned 30 degrees forward for horizontal channels and 30-45 degrees right-left to record a total of five answers in each vertical channel. All test participants were retested 30 minutes later for test reliability. We compared VOR gains across all channels, independent of gender. Results: A statistically significant difference was found in the VOR gains of all individuals in the anterior and posterior canals of the rightleft ear (p<0.05), and in the right anterior canal in women according to gender (p<0.05). A positive, high level correlation was obtained in all channels with the test retest results. Conclusions: In contrast to previous research, this one features a higher proportion of participants aged 18 to 30 and an even distribution of men and women throughout the age spectrum. The strong reliability correlation implies that the values can serve as a reference. [ABSTRACT FROM AUTHOR]

Objective: Dance is an art in which body posture and balance control and proprioceptive and vestibular systems are used effectively. Previous studies in the literature on different dance forms indicated that dance can develop plasticity in the vestibular pathways. Vestibular evoked myogenic potentials (VEMP), which is a non-invasive electrophysiological test that measures the response of the otolith organs in the inner ear to loud noise through the neck and extra ocular muscles, has a very important place in the diagnosis of vestibular disorders today. The aim of this study is to compare the cVEMP and oVEMP responses of Latin dance professionals who require a superior body and balance discipline and the adult control group. Material and Methods: In this study, the cVEMP and oVEMP responses of 60 participants consisting of 30 professional Latin dancers who had no hearing loss and no vestibular disorder and 30 age- and sex-matched healthy volunteers were compared. Results: When the cVEMP p13 and n23 latency and p13-n23 amplitude values of the professional Latin dance group and the control group were examined for both right and left ears, no significant difference was observed. When the oVEMP latency and amplitude values were compared between the 2 groups, a significant difference was observed for n10 (p=0.019) and n10-p14 (0.000) amplitude values. Conclusion: The findings showed that Latin dance can create plasticity especially on the vestibulo-ocular reflex and will contribute to clinicians that dance can be a viable therapeutic method in the treatment of vestibular disorders.

Vestibular implant (VI) is a prosthesis that aims to restore bilaterally damaged peripheral vestibular function. VI fundamentally consists of three key components. (1) Gyroscopes and/or accelerometers, (2) An external processor, and (3) implanted stimulator. VI is applied to patients with bilateral vestibulopathy (BVP). In order to restore peripheral vestibular function, a new artificial (electrical) baseline stimulation needs to be created as the peripheral vestibular physiology is bilaterally damaged in patients with BVP. After adjusting the new artificial baseline stimulation with the vestibular implant, motion modulations are applied in order to adapt the individuals to the new electrical stimulation. VI research-based implantation criteria basically consist of 2 main processes: Bilaterally reduced or absent peripheral vestibular function as a result of the caloric test, rotational chair test (video) head impulse test and (2) the presence of severe vestibular function with the chronic symptoms such as imbalance and oscillopsia. However, one should pay attention to the existence of extra criteria. Regarding VI surgery, two different types of surgical approaches, intralabyrinthine and extralabyrinthine, can be used. Although both approaches have pros and cons, the most preferred approach is the intralabyrinthine approach. Intraoperative measurements are also performed during the surgery in order to assess the integrity of the implant and the appropriateness of the placement of the electrodes. The VI started with animal experiments and has been currently continuing with research based on humans. The aim of this review is to address fundamental knowledge and convey the scientific results on vestibular implants. [ABSTRACT FROM AUTHOR]
