음파진동의자의 복합감각 자극에 따른 신경 인지기능 평가 = Evaluation of Neurocognitive Function on Complex Sensory Stimulation of Acoustic Wave Vibration Chair

다국어 초록 (Multilingual Abstract)

The purpose of this study was to evaluate the neurocognitive function of young adults due to complex stimulation of sonic vibration chair system combined with meditation music and whole body vibration. Subjects consisted of 10 males and females (5 males and 5 females) in 20s. As a method for evaluating the cognitive function of a sonic vibration chair combined with complex sensory stimuli, the accuracy and response time normality test of each test item was performed by means of Shapiro-Wilk Test. Then, we used the corresponding sample t-test if the normal distribution was followed, and Wilcoxon's sign rank test if the normal distribution is not followed to validate the cognitive function evaluation for the acoustic vibration chair combined with the complex sensory stimulus. Accuracy was significantly improved in the visual continuity test, the short-term test, language learning test, and audiovisual response time test. The response time tended to be significantly shortened in the audiovisual response time test. The result of this study suggest that meditation music and whole body vibration can improve attention, memory, and executive function through stimulation of the frontal lobe and right superior parietal lobule. In addition, through the meditation music, the language fluency was improved, and the response to the visual stimulus was greater than the response to the auditory stimulus.

본 연구는 명상음악 및 전신진동운동이 결합된 음파진동의자 시스템의 복합감각 자극으로 인한 청장년층의 신경 인지기능을 평가하고자 한다. 피험자는 20대 남녀 10명(남성 5명, 여성 5명)으로 구성되었다. 복합 감각 자극이 결합된 음파 진동 의자에 대한 인지기능 평가방법으로 Shapiro-Wilk Test.를 이용하여 각 검사항목의 정확도 및 반응시간의 정규성 검정을 우선적으로 수행하였다. 그 후, 정규 분포를 따르는 경우 대응표본 t-검정을 이용하고, 정규 분포를 따르지 않는 경우 윌콕슨의 부호 순위 검증을 이용하여 유효성을 검증하고자 하였다. 정확도는 시각 연속 수행력 검사 및 시각 단기 검사, 언어 학습 검사, 시청각 반응 시간 검사에서 통계적으로 유의미하게 개선되었다. 반응 시간은 시청각 반응 시간 검사에서 유의미하게 단축되는 경향을 보였다. 본 연구의 결과는 명상음악 및 전신진동운동을 이용하여 전두엽 및 오른쪽 상두정소엽 자극을 통한 주의력 및 기억력, 집행 기능 향상이 가능함을 암시한다. 또한 명상음악을 통하여 언어 유창성이 개선되었고, 시각적 자극에 대한 반응 정도가 청각적 자극에 대한 반응정도보다 컸음을 확인할 수 있다.
