    A COMPARISON OF REACTION TIMES BETWEEN ADOLESCENTS WITH VISUAL AND AUDITORY IMPAIRMENT AND THOSE WITHOUT ANY IMPAIRMENT
    (Turkey Assoc Physiotherapists, 2013) Yildirim, Necmiye U. N.; Ozengin, Nuriye; Ozturk, Asuman; Ozdemir, Ozlem Cinar; Sertel, Meral; Ozturk, Seren Duzenli
    Purpose: The aim of this study was to compare the auditory and visual reaction times of adolescents with auditory and visual impairment and those of controls without any impairment in order to investigate whether adolescents who lack one sense have an enhanced ability with the other. Methods: A total of 64 adolescents with auditory impairment, 60 adolescents with visual impairment, and 59 controls without impairment, were included in the study. Visually impaired adolescents simple auditory reaction times, auditory impaired adolescents simple visual reaction time, and the controls visual and auditory simple reaction times were evaluated with the New Test 100. Results: While no statistically significant difference was found between auditory reaction times of controls and visually impaired adolescents (p>0.05), a significant difference was observed in visual reaction times of controls and auditory impaired adolescents (p<0.05). Conclusion: The reason why auditory impaired adolescents have longer simple reaction times could result from peripheral or central stimulation, changes in input processing in the cerebrum and their focus on lip reading and sign language compared to visually impaired adolescents.

    THE RELATIONSHIP BETWEEN FUNCTIONALITY, PERFORMANCE, REACTION TIME AND QUALITY OF LIFE IN THE ELDERLY
    (Gunes Kitabevi Ltd Sti, 2011) Yildirim, Necmiye Un; Ozengin, Nuriye; Ozdemir, Ozlem Cinar; Gokdogan, Feray
    Introduction: The purpose of this study was to examine the relationship between functionality, performance, reaction time and the quality of life in the elderly. Materials and Method: The study sample consisted of 98 subjects 65 years of age and over. A survey was conducted to identify their demographic features. Mini Mental State Test was administered to evaluate cognitive functioning levels of the subjects, and their quality of life was evaluated by Nottingham Health Profile. In addition, the lower extremity performance was measured by chair sit-to-stand test, functionality was assessed by stair climb power test, and the reaction time was measured by New-test Reaction Timer. Results: The mean age of the participants was 73.24 +/- 6.10 years. Of the subjects 51% were male, 40% were married and 51% had primary education. A significant negative relation was found between the Nottingham total scores and functionality and performance (p < 0.05), however, no relationship was observed in relation to the reaction times. According to the results of the linear regression analysis, functionality was the most influential variable on quality of life (p < 0.05). Conclusion: Identifying the functional muscle power loss and effects of this loss on quality of life in aging is essential for the elderly.
