Purpose : This study examined the effects of a virtual reality rehabilitation program on stroke patients' upper extremity functions and activities of daily living (ADL). Methods : The subjects were equally and randomly divided into an experimental group (n=16) to whom a virtual reality rehabilitation program was applied and a control group (n=16) who received traditional occupational therapy. The intervention was applied five times per week, 30 minutes per each time, for six weeks. Jebsen-Taylor hand function test was conducted and the subjects' Manual Function Test was measured to examine their upper extremity functions before and after the treatment intervention, and a Korean version of modified Barthel index was calculated to look at their activities of daily living. Results : After the intervention, the upper extremity functions and activities of daily living of the participants in both groups significantly improved (p<.05). However, the improvements in these parameters among the participants in the virtual reality rehabilitation program were significantly greater than those in the control group (p>.05). Conclusion : The virtual reality rehabilitation program is a stable and reliable intervention method for enhancing the upper limb functions and activities of daily living of stroke patients.

The aim of this study is to examine the effects of virtual reality cognitive rehabilitation program on cognitive function, physical function and depression of long-term care insurance nongrading elderly dementia using Daytime protection service. For achieve this purpose, 30 dementia elderly were randomly assigned in to the experimental group(n=15)and control group(n=15). All subjects performed a general therapeutic exercise and 20- 30minutes takes virtual reality cognitive rehabilitation program were conducted with experimental group 2 times a week for 8 weeks. The intervention effects were measured by using cognitive function is mini-mental states examination-Korean version(MMSE-K), visual perception is MVPT(Motor-Free Visual Perception Test), Berg's balance scales(BBS), depression test GDS-K and lower limb strength. The results of study represented that the training group showed significant improvement in MMSEK( p<.05), visual perception(p<.05), balance(p<.05), lower limb strength(p<.05) and depression (p<.05). In conclusion, the virtual reality cognitive rehabilitation training using improves visual perception included cognitive function, physical function included balance, and lower limb strength and depression. These results suggest that virtual reality training using virtual reality cognitive rehabilitation program is feasible and suitable for mild dementia.

Purpose : The aims of this study was to conduct a systematic literature review with meta-analysis to investigate the effect of virtual reality based rehabilitation program on balance of patient with stroke in Korean studies. Method : The studies for analysis were searched in electronic databases(Research Information Sharing Service; RISS, Korean Studies Information Service; KISS, DBpia, e-articles, National Assembly Library). The key words for search were 'virtual reality', 'stroke', and 'balance' and only randomized controlled trials and clinical controlled trials were included. Of 40 studies identified in the search, 20 studies met the criteria of this study and included in this meta-analysis. Result : The results were as follows: 1) The overall effect size of virtual reality based rehabilitation program was 0.557(95% critical interval; 0.340~0.774). 2) In the analysis of sub-categorical variables, effect size was as follows; the commercial game type(0.621) > virtual environment type(0.335); the dynamic balance measurement(0.750) > static balance measurement(0.226); randomized controlled trial(0.653) > clinical controlled trial(0.275); and thesis type(0.706) > article of journal type(0.339). 3) In the analysis of sub-continuous variables, as time of program(per session) increased, the balance increased(p<0.05). Conclusion : The results of this study showed that virtual reality based rehabilitation program moderately improves the balance of stroke patient. Further studies are recommended to investigate the effect of sub-variables related to virtual reality programs on motor functions of patient with stroke.

PURPOSE: This study compared the effects of computer-based and virtual reality-based cognitive rehabilitation programs on the cognitive function, upper limb function, activities of daily living, and their impact on the prefrontal cortex in convalescent stroke patients. METHODS: Ten recovering stroke patients were assessed for their cognitive function, upper limb function, and daily living activities using the Neurobehavioral Cognitive Status Examination, the Korean version of the Fugl-Meyer Assessment, and the Korean version of the Modified Barthel Index. The prefrontal cortex activity was measured with functional Near Infrared Spectroscopy. The virtual reality-based cognitive rehabilitation group utilized a program of daily living activities delivered via a laptop and Oculus Rift. The computer-based cognitive rehabilitation group performed various cognitive tasks on an all-in-one PC. Both groups underwent cognitive rehabilitation training for 30 minutes per day, three times a week, for six weeks, with identical conventional rehabilitation therapies in the hospital. RESULTS: Both programs positively impacted the cognitive and physical functions. On the other hand, the virtual reality-based cognitive rehabilitation program had a larger influence on improving the cognitive and physical functions of convalescing stroke patients. CONCLUSION: The virtual reality program suggests its potential to enhance cognitive and physical functions in convalescent stroke patients through increased engagement, focus, real-time feedback, and game elements, making it a promising rehabilitation approach.

Purpose : The purpose of this study was to investigate the effects of virtual reality(VR) program on standing balance in stroke with sensory deficit. Methods : Subjects were assigned randomly to either VR group (n=28) or the control group (n=31) when study began. Both groups were conducted electricity therapy, exercise therapy 5 times per week during six weeks, and a group who have VR group 3 times per week during six weeks. Both groups assessed for standing balance before and after virtual reality program. Results : In standing balance, the virtual reality program which have sensory deficit in stroke group, open eyes from the center area of the body and center line significantly reduced the training period(p<.05). The virtual reality program to instantly move the weight through maximum voluntary safety limits to sensory deficit of virtual reality program(p<.05). Conclusion : Stroke patients with sensory deficit affects the recovery of the standing balance. In addition, virtual reality program was stroke patients with sensory deficit affects the recovery of standing balance.
