Objective : The purpose of this study is to repeatedly conduct task-oriented training in scopolamine-induced dementia rats and as a result observe changes in the content of acetylcholine, a marker of cognitive function and central nervous system plasticity, to identify the improvement effect of dementia. Methods : It consisted of two groups. One group I was that did not perform task-oriented training in scopolamine-induced dementia rats and the other group II was that performed task-oriented training. Task-oriented training involved stretching, grasping and moving arms and walking obstacles on the legs. We performed a quantified passive avoidance test in the measurement of memory for cognitive function and compared the change in the content of acetylcholine for the plasticity of the central nervous system. Results : The results of the study are as follows: First, there was a significant improvement in cognitive function since the 4th days after task-oriented training of scopolamine-induced dementia rats(.00). Second, task-oriented training applied to scopolamine-induced dementia rats showed a significant increase in acetylcholine content. Conclusion : In this study, task-oriented training, which is often performed on senile dementia patients during occupational therapy intervention, was scientifically demonstrated in scopolamine-induced dementia rats by enhancement of cognitive function through memory improvement and increase in the content of acetylcholine confirming central nervous system plasticity.

Objective : The aim of this study was to evaluate the current knowledge regarding constraint-induced movement therapy (CIMT) and its application in clinical practice by physiatrists and therapists in pediatric rehabilitation area in Korea. Methods : Online survey via E-mails was sent to a total of 510 members (204 physiatrists and 306 therapists) of the Korean Society of Pediatric Rehabilitation and Developmental Medicine (KSPRDM). Results : The response rate was 35.1% (179 of 510). A total of 179 questionnaires was completed by 39 physiatrists, 89 physiotherapists, 48 occupational therapists, and 3 speech therapists. 45.8% of responders had worked over 6 years in the pediatric rehabilitation setting and a total of 58.1% (n=104) of the sample had used CIMT. The main limitations of clinically applying CIMT included limited staff and inappropriate clinical setting (35.1%, n=61), lack of understanding (19.5%, n=34), and developmental issues of function on the unaffected side (13.8%, n=24). The cooperation of patients (77.6%, n=76), cognitive/behavioral factors (42.9%, n=42), and cooperation of caregivers (25.5%, n=25) were the 3 major concerns that could be limitations with CIMT. Conclusions : Although considerable evidence supports the use of CIMT, many of physiatrist and therapists do not apply this method in practice. The improvement of limitations is necessary for wide use of CIMT in clinical practice in Korea.

Objective : The purpose of this study was to develop an assessment tool to measure Korean occupational balance. Methods : From March 2017 to July 2019, preliminary questionnaire was prepared through analysis of previous research and expert focus meeting, and preliminary questions were selected through the Delphi survey. In order to verify the validity of the items, Rash analysis was conducted to analyze the persons and items fitness, the distribution of item difficulty, separation reliability, and the appropriateness of the rating scale. Results : Among 141 subjects, 9 (6.38%) in time use and 11 (7.80%) in the occupation area were inappropriate subjects. As a result of analyzing the appropriateness of the items except for the inappropriate subjects, the 3 items were judged as ineligible items, but 1 item of the occupation characteristics was finally deleted based on the theoretical and clinical grounds. In the analysis of the scale, 4 points were more appropriate than the 5 point scale, and the separation reliability was .86～.94. Finally, 3 categories (time use, occupation area, occupation characteristics) and 18 items were selected. Conclusion : The occupational balance assessment tool was selected three categories and 18 questions finally, three categories and 18 questions, and was developed on a four-point Likert scale. Further research needs to prove the concurrent validity of the K-OBA and to analyze the factors that influence the occupational balance.

Objective : The purpose of this study is to investigate the relationship between the leisure experience, leisure identity, depression, and self-respect of the elderly with sleep disorders through leisure activities. Methods : The elderly with sleep disorders were applied for more than 4 weeks from March to July, 2018. Depression, self-respect, and sleep quality before and after the application of leisure activities were analyzed by the corresponding sample t test. The leisure experience, leisure identity, and change in leisure activities were analyzed by SEM(structural wearing model analysis through confirmatory factor analysis. Results : The results of this study are as follows. First, there was a significant difference in depression level before and after leisure activities (p = .000). Second, there was no significant difference in self-respect before and after leisure activities (p = .182). Third, there was a significant difference in the quality of sleep before and after leisure activities (p = .000). Fourth, the effects of leisure experience, leisure identity, and change on leisure activities showed that leisure experience influenced leisure identity and change. However, leisure identity affected depression and sleep quality among the factors of change. Conclusion : A decrease in the quality of sleep that can occur in the elderly can affect the quality of life. It was found through experiments that the leisure activities of elderly people with sleep disorder can bring about positive changes in depression level and sleep quality of the elderly.

Objective : The purpose of this study was to investigate the effect of cognitive level of mild cognitive impaired elderly living in the community on participation in activities and social networks as well as leisure and daily life activities. Methods : The elderly people aged 65 years or older living in the community were selected for the mild cognitive impairment with a score of MMSE-K of 15 or more and 23 or less. MoCA-K was applied in order to examine the cognitive abilities of the subjects and K-ACS and LSNS-18 were applied to confirm the activity participation level and social network index. Results : As a result of examining the relationship between cognition and activity participation, various sub-abilities(spatio-temporal abilities, vocabulary abilities, attention, abstract thinking) of cognition had a significant influence on instrumental activities of daily living, leisure activities and social activities. In addition, all of the sub - abilities of cognition showed a significant correlation with sub-elements of social network. Conclusion : Through this study, it was found that the general elements of cognition influenced activity participation and social network of various areas of mild cognitive impaired elderly people. We suggest that measures for enhancing participation and social participation of the elderly with mild cognitive impairment are provided through follow up studies.

Objective : The purpose of this study was to investigate the factors influencing stroke in community-dwelling adults. Methods : This study used raw data from the community health survey in 2016. Among the 228,452 subjects who participated in the survey, 225,003 (98.5%) of them were included in the analysis of this study. The sociodemographic characteristics were selected as gender, age, region, income, marital status, and comorbidity was selected as osteoporosis, hypertension, diabetes, dyslipidemia, myocardial infarction and arthritis. Health-related quality of life was assessed by EuroQol-5 Dimension(EQ-5D) and the subcategory of EQ-5D (mobility, self-care, usual activities, pain/discomfort, anxiety/depression) were included in the analysis. Dependent variables were stroke, and the independent variables were the 16 variables described above. Statistical analysis was performed using binomial logistic regression analysis. Results : In sociodemographic variables, stroke was predicted by men, aging, and lower income levels. In comorbidity variables, stroke was predicted by hypertension, diabetes mellitus, hyperlipidemia, and myocardial infarction. In sub-domains of health-related quality of life, stroke was predicted by self-care, usual activities, mobility, anxiety/depression, and pain/discomfort. Conclusion : These finding suggest that it is needed development of a customized health promotion program for the improvement of self-care and activities of daily living in community-dwelling stroke survivors.

Objectives : This study was to compare the level of activity participation(instrumental activities, leisure activities, and social activities of living) and quality of life for elderly people with and without stroke, and to analyze the correlation between the level of activity participation and quality of life in their scores on measures. Methods : The Korean Activity Card Sort(K-ACS) was conducted among 25 elderly people with stroke and 25 elderly people without stroke living in Busan, and their level of activity participation and quality of life were evaluated using the The Medical Outcome Study 36-item Short Form Health Survey(SF-36). Results : Elderly people with and without stroke both showed a significant difference in the retained level of activity participation, instrumental activities of daily living, leisure activities, social activities, and the SF-36 score. The scores of the elderly people with stroke for the retained level of activity participation and instrumental activities of daily living in the Korean Activity Card Sort had a significant correlation with the SF-36 score, whereas leisure activities and social activities did not show a significant correlation with the SF-36 score. Among the elderly people without stroke, there was a significant correlation between scores for the retained level of activity participation, leisure activities, and social activities of living in the Korean Activity Card Sort and the SF-36 score, but there was no significant correlation between instrumental activities of daily living and the SF-36 score. Conclusion : The level of activity participation and quality of life could be considered to correlate with one another, and an intervention to improve the activity participation of elderly people with stroke would help to enhance their quality of life.

Objective : This study aimed to identify types of leisure time spending of the Korean elderly according to the data of Hours of Living 2014 from National Statistical Office, and compare and analyze features of leisure time spending based on general characteristics of the elderly. Method : This study has only adopted the data of 9228 elder people whose ages were above 65, and their general characteristics and time spending features form the data of Hours of Living 2014. The final comparison and analysis has been made through behavior classification (1 major classification, 7 medium classification, 39 minor classification), which reflects how the elderly spend their leisure time according to their household and personal characteristics. Result : Firstly, the Korean elderly were found to spend most of their leisure time with media. Secondly, analyzing the features of leisure time spending based on household characteristics of the elderly, their gender and household income showed significant differences in all types of leisure time activities except for cultural and sightseeing activity. And their marital status showed significant differences in most of the leisure time activities excluding leisure time activity with media and cultural and sightseeing activity. Thirdly, analyzing the features of leisure time spending based on personal characteristics of the elderly, their education level has made significant differences in all types of leisure time activities. As for their economic activity status and average monthly income, they showed meaningful differences in most of the leisure time activities excluding cultural and sightseeing activity and ritual activity. Conclusion : We should help to find meaningful occupation within personal contexts and arrange it properly with balanced leisure time spending. Moreover, it is highly important to have appropriate occupational approach to prevent social isolation of the Korean elderly, and ensure their fruitful and successful later life.
