안구추적 연동형 주의력 훈련시스템이 뇌손상자의 인지능력에 미치는 효과 : 예비연구

국문 초록 (Abstract)

목적 : 본 연구의 목적은 안구운동이 동반된 주의력 훈련이 인지장애가 있는 뇌손상 환자의 주의력 및 인지 능력 회복에 긍정적인 영향을 미치는 효과를 알아보기 위한 예비연구이다. 연구방법 : 인지장애가 있는 뇌손상 환자 7명에게 16주 동안 총 48회 안구운동이 동반된 주의력 훈련을 집 중적으로 실시하였다. 중재 도구는 안구추적 연동형 주의력 훈련시스템인 컴퓨터 기반 인지재활 프로그 램(Eye-tracking & ear system based Attention training System; EYAS)을 적용하였다. 중재 전후 인지능력의 변화를 알아보기 위하여 한국형 간이 정신상태검사(Mini-Mental State Examination for Korean; MMSE-K), 전산화 신경인지기능검사(Computerized Neuro-cognitive function Test; CNT), 운동시지각검사(Motor-free Visual Perception Test; MVPT)를 실시하였다. 결과 : 안구추적 연동형 주의력 훈련시스템으로 안구운동이 동반된 주의력 훈련을 참가자에게 중재 프로그 램으로 적용한 후 주의력, 정보처리속도, 기억력 및 시지각이 향상되었다. 아이어스 중재 전보다 중재 후 MVPT 평균점수가 높았다(p<.01). MMSE-K 역시 평균 점수가 향상 되었다. 시각 주의력과 정보처리 속도에서 효과를 알아본 결과 CNT의 VCPT(Visual Continuous Performance Test)(p<.05)와 VCCPT(Visual Controlled Continuous Performance Test)(p<.01)에서 중재후가 중재전보다 평균점 수가 높았다. 아이어스가 기억력에 긍정적인 영향을 미친다는 것을 CNT 평가를 통해 알 수 있었는데 CNT의 VST(Visual Span Test)(p<.01)와 DST(Digit Span Test)(p<.05)에서 평균점수가 향상되었 다. 중재 후 VST 역순 검사에서는 평균값 상승이 있었고, DST 역순 검사에서는 중재 전후 평균값에서 유의한 차이를 보였다(p<.05). 결론 : 안구운동이 동반된 주의력 훈련은 인지저하가 있는 뇌손상 환자의 주의력, 정보처리 속도, 시지각, 기억력 향상에 긍정적인 영향을 준다는 가능성을 알 수 있었다. 안구운동은 주의력과 관련성이 있고, 주 의력의 향상은 다른 인지능력에 긍정적인 영향을 줄 수 있다. 향후 연구에서는 구조화된 실험설계로 효 과검증을 실시할 필요가 있다.

Objective: The purpose of study was to verify the clinical effect of a attention training with eye movement program(called EYAS) for recovering the attention and cognition in brain injury. Methods: For this purpose, 7 stroke and TBI with cognitive disabilities participated in a clinical experiment to verify the effect of attention training with eye movement program. The intervention tool was the eye tracking-linkaged attention training system(EYAS) which is computer–based cognitive rehabilitation program. All participant were evaluated with four standardized assessment tools(MMSE-K, MVPT, CNT) before, middle, after the planned intervention sessions. Cognitive interventions were intensively carried out for 16weeks, half an hour per session, 3 times a week. Results: The results were as follows. Three intervention periods for MVPT and CNT showed differences in cognitive abilities after the interventions as expected. The attention, response speed, memory, visual perception were improved significantly compared to before intervention. The cognition(MMSE-K, MVPT, CNT) scores after EYAS interventions were higher than before it's interventions. Conclusion: These results indicate that the attention training with eye movement program have effects on improving cognitive abilities(memory, visual perception) and response speed in brain injury patients. Further studies are needed to verify the effect on various group and more participants(ex, child).
