Abstract

Altın, B. Investigation of the Effect of Cognitive Tasks on Balance Performance in Young Adults in Different Experimental Conditions, Hacettepe University, Graduate School of Health Sciences, Audiology and Speech Disorders Program, Ph.D. Thesis, Ankara, 2019. The aim of this study is to investigate the relationship between balance and different cognitive activities by creating different conditions and to explain the connection between the components of balance and cognitive tasks. In the study, 30 healthy young adults aged 18-40 were given visual and auditory tasks during functional balance tasks. Sensory Organization Test (SOT) and Adaptation Test (ADT) of Computerized Dynamic Posturography (CDP) were used to evaluate balance performance. Visual attention (VA) tasks were presented in the virtual reality environment. In auditory attention (AA) tasks the sounds with different frequency and intensity characteristics were presented from the computer speaker. When the balance scores were compared in D1 condition of DOT, a statistically significant difference was found between all dual VA task (DT-VA) and single task (ST) scores (p=0.001) but there was no statistically significant difference between TG and DT-AA scores (p=1.00). There was a statistically significant difference between VA2 and all dual tasks (p=0.001), but there was no significant difference between the other VA tasks and AA (p=1.00). When the balance scores were compared in D4 condition of DOT, there was a statistically significant difference between all DT-VA tasks compared with ST and DT-VA scores (p=0.001) and there was no statistically significant difference between ST and DT-AA scores (p=0.80). A significant difference was found between the sway energy scores of AA and ST in the ADT up condition (p=0.001). While there was a significant difference between DT-VA and ST and DT-AA (p=0.001), no statistically significant difference between ST and DT-AA in the ADT down (p=0.321). It is thought that the results obtained from this study will contribute to understanding the relationship between the attention and balance system and the effects of virtual reality technology
