Objectives: This study aimed to investigate the effects of a 4-weeks intervention using a monitor-based virtual reality game intervention(VRI) on the cognitive function and activities of daily living of individuals with acute stroke. Methods: For this study, 19 individuals with acute stroke were recruited. To compare the effectiveness of the VRI and the computer based cognitive intervention(CBCI), Each of the two groups were provided different interventions a 30 minutes a day, 5 times per week for 4 weeks, and to measure the effects of the intervention, the TMT A&B, DST, RKMT and K-MBI were performed before and after interventions. Results: Both the VRI and the CBCI were found to have significantly improved the cognitive function and activities of daily living, and the difference in change compared between groups showed that the effectiveness of the VRI was significantly higher. Conclusion: Based on the findings of this study, the monitor-based VRI is anticipated to prove useful as an effective intervention for the cognitive function and activities of daily living of stroke patients. Furthermore, the utility of monitor-based VRI is likely to be high in clinical occupational therapy.

The subjects of this study were 30 hemiplegia patients whose disease duration was over 6 months, and they were divided at random into a control group (n=15) receiving traditional rehabilitation therapy and an experimental group (n=15) receiving both traditional rehabilitation therapy and training using IT based EMG biofeedback. The program was applied for a total of 4 weeks. In order to examine the subjects' functional recovery, we measured their upper limb function using FMA and MFT, and activities of daily living using FIM before and after the training. Comparison between experimental groups in the study of upper extremity function improved after training in all tests was higher compared to the control group significantly (p<.05), but activities of daily living were not significantly different in. The results of this study were as follows. we concluded that stroke patients receving intensive IT based EMG biofeedback showed upper extremity functional recovery.

The purpose of this study was to evaluate the effects of a computerized cognitive training(CCT) on cognitive, depression, life satisfaction and activity of daily living in older adults with mild dementia. The participants were 32 older adults diagnosed with mild dementia who reside in nursing hospital and were randomly divided into an 16 for an experimental group and 16 for a control group. A CCT was performed for a day/week for 8 weeks in an experimental group. The CoTras-G was used for CCT. The MMSE-K, SGDS-K, ELS and BI were administered to the experimental group and the control group in the same way in order to examine the effects of CCT. The difference of the effects between before and after a CCT conduction were identified by paired t-test. Moreover, the Mann-Whitney U-test was conducted to identify differences in variances between groups. Only participants in the experimental group reported significant improvements in cognitive function, depression, life satisfaction and activity of daily living when compared to those in the control group after CCT. There was a significant difference in cognitive function, depression, life satisfaction and activity of daily living between the experimental group and the control group after CCT. These findings suggest that the CCT can be used as effective cognitive training program to improve cognitive function, depression, life satisfaction and activity of daily living in older adults with mild dementia.

국민 소득수준의 향상은 복지사회를 이룩하기 위한 기본요건이지만 상대적으로 경제개발 및 근대화 과정에서 야기되는 사회문제나 건강생활에 저해되는 요인의 발생방지 대책이 결여된다면 이는 결코 이상적인 발전일 수 없을 것이다. 사회보장제도에서의 가장 중요한 기능이 물론 경제적 조건의 개선이지만 건강조건의 개선 역시 이에 못지 않게 중요한 기능의 하나인 것이다.

적절한 영양섭취는 노인에서 나타날 수 있는 각종 생활습관질환의 예방과 치료에 도움을 줄 뿐 만 아니라, 신체 기능을 향상시켜 삶의 질 향상에 중요한 역할을 한다. 노인계층은 노화에 수반되는 각종 생리기능의 저하, 사회심리적 고립, 유병상태 및 투약, 활동량 저하에 따라 식생활이 불량해지며, 이는 곧 영양상태 불량을 초래하여 건강을 더욱 악화시킨다. 우리나라는 현재 노인 인구의 급격한 증가에 따라 지역사회 노인 대상의 각종 보건영양서비스 필요성이 대두되고 있다.(중략)

The present study was to investigated the effects of motion-based virtual reality training on cognitive function and activities of daily living in patients with stroke. This study was participated in forty one patients with acute stroke. All subjects were randomly assigned into either the experimental group(n=20) or the control group(n=21). The both groups received the conventional occupational therapy during 30 min a day, 5 a week, 4 a weeks. Additionally, experimental group performed motion-based virtual reality training on each session during 30 min/day, and control group conducted conventional occupational therapy on each session during 30 min/day. The outcome measures were the LOTCA(Loewenstein Occupational Therapy Cognitive Assessment), TMT(Trail Making Test), VM(Visual Memory), K-MBI(Korean Modified Barthel Index). In comparison of change score of cognitive function, the experimental group showed a significantly greater improvements in attention and visual working memory than the control group(p<.05). As a result for change score of activities of daily living, the experimental group showed a significant greater improvement in self care than the control group(p<.05). Our findings suggest that motion-based virtual reality training may have a effects of the improvements of cognitive function and activities of daily living than conventional therapy in patients with acute stroke.

The purpose of this study was to investigate the effects of cognitive rehabilitation programs using Virtual Reality(VR) content on the daily living abilities such as cognitive abilities, depression, and upper extremity functions of the elderly. The study group analyzed the effectiveness by separating the experimental group, which is the virtual reality cognitive rehabilitation application group, and the control group, the universal cognitive stimulation program application group. As a result of the study, the MMSE-K score improved by 13.0% in the experimental group and 2.3% in the control group. The improvement in each area of the experimental group was found to be 3.1% MBI, 7.1% MFT(Rt.), 3.5% MFT(Lt.), and 25.4% K-GDS. As a result of comparing the pre-post score change between each group, there was a significant difference between groups in daily living ability (p<.001) and MFT(Rt.)(p<.01). In addition, as a result of comparing the changes in absolute alpha waves to confirm the degree of depression through brain waves, there was no statistically significant difference. However, in the experimental group, it was confirmed that the average value increased to a positive value. This study is an experiment to verify the effectiveness of the cognitive rehabilitation program using virtual reality contents, and suggests a new intervention method to maintain and improve the daily life ability, cognitive function, depression and upper extremity function of the elderly.

This study was performed to investigate the impact of the Neurocognitive Rehabilitation Therapy on the upper limb function recovery of patients with stroke and their abilities to perform daily activities and to provide basic data for a long-term treatment. A total of 30 patients with hemiplegia that occurred due to stroke were recruited as subjects of the present study, and 15 patients were randomly assigned to a Neurocognitive Rehabilitation Therapy group and a conventional treatment group, respectively. And, tests were performed over four weeks, five times a week, and 30 minutes a session. Manual Function Test(MFT), Fugl-Meyer Assessment Scale(FMA), and Korean-Modified Bathel Index(K-MBI) were used to measure the degree of the functional recovery before and after the experiment. According to the data of this study, in the upper limb function test, the Neurocognitive Rehabilitation Therapy group showed significant increase of the measurement values of MFT and FMA(p <.05), and when the difference between the two groups were compared, the upper limb function showed a statistically significant difference. In the daily activity performance test, only the Neurocognitive Rehabilitation Therapy group showed a significant improvement of K-MBI value(p <.05). Based on the results of the present study, it was demonstrated that the Neurocognitive Rehabilitation Therapy was effective in enhancing the upper limb functions and daily activity performance of patients with stroke.
