Objective : The purpose of this study is to determine the impact of assistive device on the perform in ADL and life satisfaction. Methods : From August 1 through August 31 in 2004, the researchers visited forty physical disability people who reside in Gyeong-nam Gimhae-si to evaluate ADL using survey. The six researchers, who already finished all of FIM(functional independence measure) evaluation, individually interviewed the subject. The survey consists of 9 general character questions, 7 assistive device questions, and 3 satisfaction of life questions. Especially, the satisfaction of life questions based on 5 point scales by rehabilitation medical service, family support level, and participation level in the country. Results : Whether the subjects use assistive device or not, there was no difference to the subject's ADL skills. According to the subject who do not use the assistive device, there were statistically no difference at all in their satisfaction of rehabilitation medical service. However, according to the subject who use an assistive device with family support and participation in the country, they all showed high satisfaction (p<0.05). Conclusion : When the people with physical disabilities use the assistive device, family support and participation in the country highly effected in their satisfaction (p<0.05). Therefore, future study should investigate more people with physical disabilities who use an assistive device by considering regional characteristic.

Objective : The purpose of this study was to investigate the effect of knowledge of results (KP) and performance of results (KR) on motor learning in adult with mental retardation. Methods : One female subject participated in experiment. The study employed alternative treatment design. The learning tasks were two different typing with functional independence. Subject practiced typing provided with knowledge of results and performance in motor learning skill after baseline measurement. Performance time and error(%) were measured and analysed at baseline, immediately after practice, 1 hour later after practice, and 2 days later in the end of practice for retention. Results : Performance time and error were decreased after applying both interventions. Immediately after practice, the reduction of performance time was increased in KP more than in KR. But, in 1 hour later after practice, and 2 days later in the end of practice, the reduction of performance time was increased in KR more than in KP. The percentage of error reduced in KR more than in KP at all sessions. Conclusion : The practice with KR facilitated and maintained motor learning skills more than with KP. It suggest that practice with KR is desirable for improving of motor learning skill in adult with mental retardation.

Objective : The purpose of this study was to research velocity of reaching and spatial coupling of upper extremity during various bimanual reaching target activities. Methods : Experiments were performed on 30 subjects. They had no medical history of neurological and surgical problems with their arms and right handed persons. Using regular cups and a pen, they moved the cup and pen from one point to another.Reaching target activities: (1) to reach for and grasp a cup and then place on the other spot with only left hand, (2) same activity to the first activity with both hands simultaneously, (3) while doing same activity to the first activity with left hand, to reach for and grasp a pen and then place on the other spot in front of the with right hand, (4) while doing same activity to the first activity with left hand, to reach for and lift a cup and then place on the cabinet.We analyzed the peak angular velocity in elbow motion and displacement in wrist position using 3-D motion analysis system. Results : The peak angular velocity was increased significantly in #2 task comparing to in #1 task. The peak angular velocity was decreased significantly in #3 task comparing to in #2 task. The displacement from the table in Z-axis was increased significantly in #4 comparing to in #2. Conclusion : The result showed that bilateral activity enhanced angular velocity in elbow motion during upper extremity task. and the movement with one upper extremity affected the other. This is the basic study for improving reaching performance in people with neurological disease.
