Background: Since the vestibular system has an important role in normal cognitive development, learning, visuospatial abilities, concentration, multitasking ability, short-term memory, etc. It is very important to evaluate the vestibular system in addition to posture, gait and general motor skills in children with dyslexia. The aim of this study is to test 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. Methods: Fifteen participants diagnosed with “dyslexia” were included in the study group (SG), and fifteen healthy participants were included in the control group (CG). All groups underwent Montreal Cognitive Assessment Test (MoCA), 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°/s2 randomly to the right and left in the plane of the horizontal semisircular canal (SCC). Statistical analysis was performed using descriptive statistics and Mann Whitney U test on IBM SPSS 22.0 program. Results: Comparisons between the two groups showed that there was a significant difference between the percentage of total correct answers in the right ear and the percentage of total correct answers in the left ear (p= 0.003; 0.006). SG percentage values were obtained lower than CG percentage values. While there was a significant difference in all parameters (4000-5000-6000°/s2) in the right side stimulation, there was no significant difference for all parameters on the left side. In addition, although there was no significant difference between the groups according to the PBS score, the SG scores were lower (p= 0.062). Conclusion: As a novel test, fHIT, revealed the difference in functionality of vestibular performance in the dyslexia group. In the dyslexia group, fHIT may be helpful in evaluating and monitoring the vestibular system
