목적 : 본 연구는 중심부 암점을 가진 환자에게 한글 기반의 중심외보기 훈련 소프트웨어를 적용하여 그 효 과성을 파악하고자 하였다. 연구방법 : ABA 단일대상연구(single-subject research design) 설계를 위해 중심부 암점을 가진 2명의 환자에게 훈련 전후 기초선 각 3회기, 중심외보기 훈련은 8회기를 시행하였다. 매회기 훈련 종료 후에 단 문읽기속도를 측정하였고, 훈련전과 훈련 후에 일기활동 능력을 평가하기 위하여 캐나다작업수행측정 (Canadian Occupational Performance Measure; COPM)와 운동처리기술평가(Assessment of Motor and Process Skills; AMPS)를 시행하였다. 결과 : 중심외보기 훈련 결과 대상자 모두의 읽기속도가 훈련 전보다 훈련 후에 2표준편차 이상 증가하였고, 특히 훈련 2-3회기에 큰 증가세를 나타냈다. 전반적인 일상생활활동 능력에서는 훈련 전후 변화가 없었 으나, 읽기와 관련된 활동에서는 의미있는 향상을 나타냈다. 결론 : 본 연구를 통하여 한글기반의 중심외보기 훈련 프로그램이 중심부 암점을 갖고 있는 환자의 읽기활동 수행 수준을 향상시킬 수 있음을 확인하였고, 국내 임상현장에서 적용할 근거를 마련하였다.
Objective : To examine the effects of the eccentric viewing training software on reading and Activities of Daily Living(ADL) for individuals with central scotomas in Korea. Methods : A single-subject A-B-A research design for two low-vision individuals with central scotomas was used to examine the effects. The research was conducted over 14 sessions, which included three sessions during a pre-training baseline period (A), eight sessions during an intervention period to apply eccentric viewing training software on Korean character stimulation (B), and three sessions in a post-training baseline period (A). To measure reading and ADL, participants were assessed for their reading speed, Canadian Occupational Performance Measure(COPM), and Assessment of Motor and Process Skills(AMPS). Results : An Analysis of the data showed that the participants’ reading speed increased compared to their pre-training baseline scores, showing the highest level of increase in the first two to three sessions of training. The participants improved their performance in the reading-related activities, although a comparison of their overall ADL function pre-training and post-training showed no change. Conclusion : These findings suggest that the eccentric viewing training based on specific language characters, Korean, is an effective intervention method for improvement in the reading skills of individuals with central scotomas.
