Purpose: The purpose of this study was to investigate the effects of an immersive, virtual reality-based exercise program on range of motion and dexterity in the upper extremities of stroke patients. Methods: Fifteen patients with hemiparesis after stroke participated in this study. The participants participated in Rapael Semart GloveTM, an immersive, virtual reality-based exercise program, performed for 30 minutes-, 3 times per week for 4 weeks. The Rapael Smart GloveTM program and a Box and Block Test (BBT) were used to measure range of motion and to assess dexterity, respectively, pre-and post-intervention. Results: Range of motion in pronation and supination of the forearm and flexion, extension, and ulnar deviation of the wrist improved after the intervention. Dexterity measured by BBT also improved. However, range of motion in flexion and extension of the fingers and radial deviation of the wrist did not improve. Conclusion: This study presents the effects of an immersive, virtual reality-based exercise program on hand function. In the future, a study comparing an immersive, virtual reality- based exercise program to other upper-extremity interventions for stroke patients should be conducted. A study about the effects of an immersive virtual reality program on activities of daily living is also needed.

A Care farm is known to have positive effects on various people in psychological, physical, and social aspects. However, care farm services for the disabled, transportation disadvantaged, and socially disadvantaged are limited. This study conducted a demand survey in order to provide basic data for development of the Agro-Healing Virtual Reality Therapy(AVRT) system. The respondents were the ordinary person(n=127) and the disabled person(n=72), and the survey items consisted of 4 categories and 20 items, including intention to use AVRT, requirements for use, factors to be considered when developing the system, and content and program preferences. The intention to use a AVRT was found to be at a high level of 80% or more by respondent characteristics. In addition, similar results were shown in all items such as virtual reality experience, willingness to use, appropriate use time, and willingness to pay by respondent characteristics, and correlation by item was determined through correlation analysis. As for the conditions of use, both sides preferred rural types and were found to have the purpose of healing. However, there were concerns about dizziness in common between system use, and in the case of the disabled person, there were difficulties in purchasing expensive equipment. In the development of the AVRT system, the part of sensory priority, important technology level, and color preference were evaluated, and the preference of content and programs to be developed in the system was identified. Fruit, vegetables, flowers, and animals preferred mandarin, tomato, tulips, and dogs first, horticultural healing preferred harvest management for the ordinary person, plant cultivation for the disabled person, and forest healing and animal education preferred walking and dog-related programs. However, agricultural work was found to be a program with high preference for making processed foods for the ordinary person and creating an animal breeding environment for the disabled person. The result of this study is expected to provide reference data that can be suggested for the development of Agro-healing Virtual Reality Therapy system.

We investigated the effects of a Virtual reality(VR) program on the proprioception and instability of functional ankle instability(FAI) patients. Among the 20s old individuals who lived in Republic of Korea; 20 people were selected through a public participation process. The 20 participants were then randomly divided into two groups, one of strength exercise(n=10) and one of balance exercise(n=10). Of the patients who had experienced an ankle sprain in the past and currently felt ankle instability, those who recorded 24 points or less on the Cumberland ankle instability tool(CAIT) were determined to have FAI. We selected the strength exercise and balance exercise in the Nintendo Wii Fit Plus as a VR program. The subjects used the program on the Wii Balance Board three times per week for 20 minutes and total 10-minute warm-up and down for four weeks. Proprioception and CAIT of the balance exercise group were improved significantly after the exercise compared to before the exercise(p<.05). Authors recommend that the balance exercise in the VR program be used as an aid for physical therapeutic intervention.
