Abstract

This research aims to assess whether neurofeedback training can reduce theta waves in adolescents. The experiment was conducted on 35 early youths living in Gyeonggi-do at youth counseling centers during April-October. According to circumstances and opinions of participants in the pre-brain analysis, they were classified into a non-training group (A), 12-week training group (B), and 24-week training group (C), containing 10, 15, and 10 members, respectively. EEG measurement and neurofeedback training was performed using the prefrontal 2-channel NeuroharmonyS and Brain Optimization program. EEG data was processed utilizing Brain Analysis ver1.3. Deducted data was converted to SPSS 21.0 to enable statistical processing. As a strategy to reduce theta through the Beta increase training, we applied the appropriate Alpha, SMR, Beta low reward training to the individual. Study results confirmed that theta waves of adolescents decreased through the prefrontal neurofeedback training. Groups (B) and (C) exhibited a greater decrease in theta waves compared with the control group.

이 연구는 뉴로피드백 훈련이 청소년기 세타파를 감소하는 데 효과가 있는지를 알아볼 목적으로 이루어졌다. 경기도에 거주하는 초기청소년 35명을 대상으로 2016년 4월부터 10월까지 6개월간 청소년상담실에서 이루어졌다. 사전 뇌기능검사에 참여한 대상자 중 참여여건과 의사에 따라 무처지 비교군(A) 10명, 12주훈련집단 실험군(B) 15명, 24주훈련집단 실험군(C) 10명으로 분류하여 설계하였다. 뇌파측정 및 뉴로피드백 훈련은 (주)파낙토스의 전전두엽 2채널 뉴로하모니S와 두뇌최적화 소프트웨어로 수행하였으며 뇌파데이터 처리는 (재)한국정신과학연구소에서 개발한 Brain Analysis ver 1.3을 사용하였다. 이렇게 도출한 데이터는 통계처리가 가능하도록 SPSS 21.0으로 변환하였다. 청소년들의 세타파 감소 훈련을 위해 개별적으로 훈련 프로토콜을 정해주었으며 베타파 증가훈련을 통해 세타파를 감소하는 전략으로서 개인에게 알맞은 알파파, SMR, 저베타파 증가 훈련을 적용하였다. 그 결과 전전두엽 뉴로피드백 훈련을 통해 청소년들의 세타파 감소가 감소하는 것으로 확인되었고, 훈련을 받은 집단(B)(C)에서, 또 훈련의 기간이 좀더 긴 집단(C)에서 세타파 감소의 폭이 큰 것으로 확인되었다.
