The aim of this study is to compare functionality of vestibulo-ocular reflex (VOR) responses to evaluate the functional properties of the vestibular system and daily balance performance in children with dyslexia and children with normal development.
Fifteen participants diagnosed with dyslexia were included in the study group (SG), and 15 healthy participants were included in the control group (CG). All groups underwent Functional Head Impulse Test (f-HIT) and Pediatric Balance Scale (PBS). f-HIT was performed with at least 15 head impulses at 4000-5000-6000°/s randomly to the right and left in the plane of the horizontal semicircular canal (SCC). Statistical analysis was performed using descriptive statistics and the Mann-Whitney U test.
SG percentage values were obtained lower than CG percentage values. Comparisons between the two groups showed that there was a significant difference in all parameters (4000-5000-6000°/s and total) in the right-side stimulation, there was significant difference for 4,000 s and total correct answers in the left side. In addition, although there was no significant difference between the groups in terms of the PBS score, the SG scores were lower ( = 0.062).
As a novel test, f-HIT, revealed the difference in functionality of vestibular performance in the dyslexia group. In the dyslexia group, f-HIT may be helpful in evaluating and monitoring the vestibular system.
本研究旨在比较前庭眼反射（VOR）反应的功能，以评估阅读障碍儿童和正常发育儿童的前庭系统功能特性及日常平衡能力。
研究组（SG）纳入15名被诊断为阅读障碍的参与者，对照组（CG）纳入15名健康参与者。所有组均进行了功能性头部脉冲试验（f-HIT）和儿童平衡量表（PBS）测试。f-HIT在水平半规管（SCC）平面内以4000-5000-6000°/秒的速度随机向左右两侧至少进行15次头部脉冲。使用描述性统计和曼-惠特尼U检验进行统计分析。
SG组的百分比值低于CG组。两组之间的比较表明，右侧刺激的所有参数（4000-5000-6000°/秒及总和）存在显著差异，左侧4000°/秒及总正确答案数存在显著差异。此外，尽管两组在PBS评分方面无显著差异，但SG组的评分较低（P = 0.062）。
作为一种新的测试方法，f-HIT揭示了阅读障碍组前庭功能的差异。在阅读障碍组中，f-HIT可能有助于评估和监测前庭系统。
