Efficacy of Vestibular Stimulation on Auditory and Visual Reaction Time in Adolescents with Down Syndrome.

Abstract

BACKGROUND - Down syndrome is associated with challenges in processing speed and reaction time throughout the lifespan. Research suggests that individuals with Down syndrome have slower reaction times than typically developing individuals. The effect of vestibular stimulation on reaction time has been studied extensively. Research indicates that vestibular exercises can have a positive impact on auditory and visual reaction time in young adults. These exercises have been shown to improve cognitive functions related to reaction time, highlighting the potential benefits of vestibular stimulation in enhancing sensory and motor systems, especially in the motor system. Studies have suggested that vestibular stimulation may lead to improvements in reaction time for both auditory and visual stimuli. Additionally, the vestibular system, responsible for balance and equilibrium, plays a role in cognitive functions, further supporting the link between vestibular stimulation and reaction time.

OBJECTIVE - To examine the effect of vestibular stimulation on auditory and visual reaction time in adolescents with Down syndrome.

METHOD– After the ethical approval from the institutional ethical committee, 42 participants were screened and 40 participants were selected based on eligibility criteria and were randomly allocated into two groups Group A (Experimental group) and Group B (Control group). Group A received vestibular stimulation with auditory and visual cues and Group B received only auditory and visual cues. Both groups received treatment for 4 times a week for 6 weeks.

RESULTS – Both groups showed significant differences when analyzed at week 6. Moreover, the mean difference showed a highly significant difference in the Experimental group.

CONCLUSION – Through this study, it was concluded that the vestibular stimulation program has a significant effect on auditory and visual reaction time in Down syndrome adolescents. Thus, the study provided evidence to support that vestibular stimulation holds a promising benefit in improving auditory and visual reaction time in Down syndrome adolescents.
