Normative vestibulo-ocular reflex data in 6-12 year-old children using video head-impulse test |
|
| چکیده انگلیسی مقاله |
Background and Aim: The video head-impulse test (vHIT) is a useful clinical tool to measure vestibulo-ocular reflex (VOR) gain that is defined as the ratio of eye velocity to head velocity. Although normative data are available for VOR gain, most studies only report horizontal semicircular canal VOR in adults, and there is lack of data in children. The aim of this study was to establish normative VOR data for 6-12 year-old children. Methods: Vestibulo-ocular reflex gain in horizontal and vertical planes was assessed on 60 healthy children without history of balance and hearing problems, through applying sudden, fast, and unpredictable head impulses. Results: The mean VOR gain was 0.99 (SD=0.05), 0.98 (SD=0.06), and 0.93 (SD=0.06) for horizontal, anterior, and posterior canals, respectively. Gain differences between genders were not statistically significant. Conclusion: Regarding the results of this study and due to the simplicity and tolerability of vHIT in children, it seems that vHIT can be used as a screening tool to diagnose vestibular disorders in children. In addition, it seems that mean VOR gain is greater in horizontal canal than vertical canal. |
