Abstract

Objective : The purpose of this study was to identify the effects of Interactive Metronome (IM) training on short-term memory and attention for children with mental retardation. Methods : For this study, single-subject experimental research was conducted using an ABA design. We observed two children, twice a week for 9 weeks, which was 18 sessions in total. We evaluated the children's brain waves without intervention and the child's pseudo randomly selected sample of one short-term memory task as assessed in the baseline A phase for three sessions. In the intervention phase the children received 40-50 minutes of Interactive Metronome training twice a week, a total of 12 sessions. The short-term memory test and long form test as assessed after treatment, without brain wave in short form test measuring. During the baseline A phase, data were collected using the same procedure as the baseline A phase. Results : After the interactive metronome training, positive changes was observed in brain waves, attentions and short-term memory. Conclusion : The results of this study expect that IM training has a potential for improving cognitive functions of children with mental retardation. In addition, the results of this study can be used as basic data in attention and short-term memory of occupational therapy intervention for children with mental retardation.

목적 : 본 연구는 상호작용식 메트로놈(Interactive Metronome: IM) 훈련이 지적장애 아동의 집중력과 단기기억력에 미치는 영향에 대해 알아보고자 하였다. 연구방법 : 지적장애로 진단 받은 아동 2명을 대상으로, 개별실험 연구방법(single-subject experimental research design)중 ABA 설계 사용하였다. 총 18회기로 매주 2회기씩 총 9주 진행하였다. 기초선 기간에는 IM 훈련을 하지 않은 상태에서 Electroencephalogram(EEG)를 부착하여 단축형 검사(short form test)로 뇌파를 측정하였으며, 대상자가 무작위(random)로 선택한 단기기억 과제로 측정을 실시하였다. 중재기 12회기는 IM 훈련을 40~50분간 실시한 후 단기기억 과제(shot-term memory test)를 측정 하였으며, 단축형 검사를 측정하였다. 재기초선 3회기에도 기초선 기간과 동일하게 진행하였다. 결과 : 상호작용식 메트로놈 훈련 후 집중력의 향상과 뇌파에서 변화를 보였으며, 단기기억 과제에서도 향상된 결과를 보였다. 결론 : 상호작용식 메트로놈 훈련은 지적장애 아동에게 집중력과 단기기억력의 향상을 위한 중재방법으로 기대되며, 본 연구는 이를 위한 근거 자료로 사용될 수 있을 것이다.
