    Normative values for semicircular canal function with the video head impulse test (vHIT) in healthy adolescents
    (2020) Emekci, Tugba; Ugur, Kadriye Serife; Cengiz, Deniz Ugur; Kilinc, Fatma Men; 33151099
    Background The vHIT device, which has a mechanism based on measuring the VOR gain, helps us to quickly evaluate six semicircular canals. Aims/Objectives The aim of this study was to establish normative values for semicircular canal function with the video head impulse test (vHIT) battery in normal adolescents. Material and methods 100 (50 females, 50 males) individuals aged 11-18 years, with a mean age of 14.99 years, were included in the study. Results As a result of the vHIT evaluations performed with vHIT Otometrics ICS Impulse A/S Taastrup, Denmark, the mean lateral canal vestibulo-ocular reflex (VOR) gain value was 0.96, the mean anterior canal VOR gain value was 0.89, and the mean posterior canal VOR gain value was 0.87, all of which were within the normal value range. Conclusion and significance While the VOR gain values and asymmetry values are within the normal value range and are similar to the literature, no statistically significant correlation was observed between these values and age. As a result, the vHIT battery is an easy, fast, and practical test method that can be used in adolescents.

    The Relationship Between Functional Head Impulse Test And Age In Healthy Individuals
    (2022) Emekci, Tugba; Erbek, Hatice Seyra; 34120922
    BACKGROUND: fHIT is an easily applicable test battery that indirectly evaluates the vestibulo-ocular reflex (VOR) from a functional perspective. AIMS/OBJECTIVES: The aim of this study was to Individuals determine the correlation between age and the percentage of correct answers (%CA) obtained in the functional head impulse test (fHIT) in healthy individuals. MATERIAL AND METHODS: A total of 105 volunteers, 50 males and 55 females, between the ages of 18 and 70 years, participated in the study. A Beon Solution fHIT system (Zero Branco (TV), Italy) was used in the study. RESULTS: In our study, a decrease in the mean %CA was observed in all semicircular canals (SCCs) with increasing age. Between age and mean %CA, a significant negative moderate (-0.311) correlation was observed in lateral SCCs, and a significant negative low (-0.257) correlation was observed in posterior SCCs (p < 0.05). In anterior SCCs, there was no statistically significant relationship between age and mean %CA (p > 0.05). CONCLUSIONS: The present study performed in a healthy population will be helpful in terms of making comparisons in studies to be conducted in various vestibular diseases. It will also be a guide for identifying pathological consequences in vestibular diseases.
