Objective: The purpose of this study was to investigate the effects of cognitive function and Activities of Daily Living (ADL) improvement with Traumatic Brain Injury(TBI) and Stroke patient through Computer Assisted Cognitive Rehabilitation (CACR) program within specific approach and hierarchial approach training program. For this investigation CACR training was administered to 14 patients diagnosed of TBI and Stroke. Method: The CACR was given to the subject patient for 1months, 5times a week and each stimulation lasted 30 minutes. Cognitive function and activities of daily living were compared pre-CACR program with post-CACR program by MMSE and FIM . Results: Summarizing the results of this investigation; 1. Statistically significant improvement in 8 items of MMSE and 11 items of FIM was found after the application of CACR program training. 2. Cognitive function showed the spastically significant improvement after CACR program within specific approach and hierarchial approach training program 3. Activities of daily living showed the statistically significant improvement after CACR program within specific approach and hierarchial approach especially hierarchial approach more statistically significant increased than specific approach.

The purpose of this case is to find effectiveness of improvement of cognitive function with head injury patients through Computer-Assisted Cognitive Rehabilitation(CACR) program within various training programs. The subjects were three inpatient persons with head injury on Rehabilitation Hospital in Yonsei University and aged 28 and 14 and 2 woman and another man. It was used PSS CogRehab program during 15 days. Cognition, perception and activities of daily living(ADL) were compared pre-CACR with post-CACR by LOTCA, MVPT and MBI. According to this case study, in spite of short-term period, the subjects had changed of performance skills of cognition, perception and activities of daily living. Results were as follows : 1. LOTCA score of 3 cases showed increasing change after CACR performance, especially perception and visuoperception organization were increased. 2. Raw score was increased and processing time was controlled adjustable of MVPT within 3 cases. 3. MBI score of 3 cases were improved, especially dressing, feeding and toileting were improved each one step.
