요약
This study was to evaluate the effects of cognitive rehabilitation training on the cognitive decline of dementia patients. Therefore the purpose of this study was to examine the influence of brain activation according to bio-feedback training in dementia. Methods : Ten dementia patients were recruited this study. Experiment was performed for 30min per session, five times a week through 4 week and two measurements before and after bio-feedback training. Brain activity was measured by Korea Electroencephalogram(EEG) system. Statistical analysis was used Wilcoxon signed rank test to know difference of EEG between pre and post-test in each group and Mann-Whitney U test was to know difference between experimental and control group. Results : Significant improvement of slow-alpha wave was observed following bio-feedback in experiment group. There was no significant change in experiment and control group. Conclusion : In this study, the bio-feedback training was effective in improving slow-alpha wave in dementia patients. It is suggested that bio-feedback training with dementia patients can be useful to ameliorate the cognitive decline. And it will be effective for prevention of cognitive function decline.

치매노인들에게 4주 동안 바이오피드백 훈련을 실시한 결과 통계학적으로 유의한 차이는 없었다. 하지만 바이오피드백 훈련을 실시한 그룹에서 알파파가 증가되는 것을 볼 수 있었다.

치매는  만성 퇴행성 질환으로 많은 임상적 특징들을 발현하는데 그 중 인지기능은 치매의 진행에 예민하고 진행정도와 비례하여 악화되는 것으로 알려져 있다. 이 훈련이 인지기능의 지속적인 감소를 막을 수 있다면 질환의 진행을 늦출 수 있는 방안이 될 수 있지 않을까 사료한다.
