This study aimed to investigate the effect of virtual reality training focus on ADL on upper extremity function and activities of daily living in stroke patients. 20 patients with chronic stroke were included in this study. The participants were divided into the experimental (n=10) or control (n=10) groups. Both groups received conventional rehabilitation therapy for 30 min a day, 5 times per week for 4 weeks. The experimental group also performed virtual reality training focus on ADL for 30 min a day, and the control group performed general virtual reality training for 30 min a day. The Fugl-Meyer Assessment (FMA) and Functional Independence Measure (FIM) scores were evaluated before and after the intervention, and both groups showed significant improvement (p<.05). Compared to the control group, the experimental group showed significant improvement in the FMA wrist score and the FIM total, self-care, and sphincter control scores (p<.05). These findings suggest that virtual reality training focus on ADL may have a positive effect on wrist function and overall ADLs compared to that using general virtual reality training in stroke patients.

Objective : The purpose of this study was to systematically analyze the methods by which virtual reality (VR)-based occupational therapy interventions are applied to disabled children and adolescents and to assess their effectiveness. Methods : The RISS, DBpia, KCI, Science Direct, and CINAHL MEDLINE databases were searched for relevant literature from January 2012 to August 2022. The main search terms used were "virtual reality," "work therapy," "youth," "virtual reality," "occupational therapy," "child," and "adolescent." A total of 16 documents were selected for analysis by the 4th stage of the PRISMA flowchart. Results : In the 16 selected studies, VR-based occupational therapy when used with children and adolescents with disabilities and was shown to have meaningful effects. Among the types of cerebral palsy covered in the studies, the most common was hemiplegia, and the evaluation tools used for measurement of the VR effect were daily activities, cognition, exercise technology, social-interaction technology, and visual-perception evaluation. Nintendo wii and Microsoft Kinect produced the VR tools most commonly used to improve motor skills and daily life. Conclusion : The results of this study indicate that VR interventions can be used effectively in clinical practice. In the future, they may assist in the diagnosis of disabled children and adolescents, in helping to select VR tools that are suitable for the purposes of intervention, and in the presentation of specific methods.

The use of virtual reality(VR)-based interventions for students with autism spectrum disorders(ASD) has received special attention as evidence-based practices for its feasiblity, practicality, and appropriateness. However, there is little research to investigate the effects of VR-based intervention for students with ASD in Korea. This study identifies and reviews studies applying VR-based interventions. In total, 13 experimental studies were found that examine the effects of VR interventions published from 1990 to 2016. The selected studies were analyzed by 6 variables including publication year, participants, research design, independent variable, dependent variable, and outcome. The results of this study showed the feasibility of the implementing VR-based interventions in various age group students with ASD. In addition, the utilization of VR techniques was particularly effective in improving a wide range of social communication skills including facial recognition, empathy, joint attention, understanding social context, and resolving issues due to limited cognitive abilities. Several recommendations for the future study on VR-based intervention for students with ASD such as interdisciplinary approach to VR-based interventions, support needs regarding characteristics of ASD, generalization and maintenance of acquired technology, and consideration for participants' cultural background. were discussed.

Purpose: The purpose of this study was to determine the effect of preoperative guidance and operating room environment experience using virtual reality on increasing satisfaction with information and reducing anxiety in preoperative patients undergoing general anesthesia and local anesthesia. Methods: A non-equivalent control group quasi-experimental design was employed. The participants were 80 surgical patients from 4 wards (40 experimental group and 40 control group) of the general hospital located in Gyeonggi-do. Data collection was conducted from June to November 2023 after completing the control group survey in January 2023. Data were analyzed using Chi-square, t-test, and Mann-Whitney U test using SPSS 23.0 program. Results: Satisfaction with preoperative information was higher in the experimental group than that of the control group. Additionally, anxiety related to surgery in the experimental group was significantly lower than that of the control group. The preoperative state anxiety score in the experimental group was not significantly lower than that of the control group. Conclusions: These results suggest that providing patient education and information using virtual reality technology can not only alleviate patients' anxiety related to surgery, but also have the potential to be used as an effective intervention to improve positive patient experiences.

Objective : The purpose of this study was to verify the effect of virtual reality interventions (VRIs) on cognitive function in individuals with stroke through a systematic literature review and meta-analysis. Methods : We reviewed randomized controlled trials (RCTs) the last 10 years using academic databases. PubMed, MEDLINE, and CINAHL were used for international studies, and DBpia, KISS, Kyoboscholar, and e-article were used for Korean studies. For the quantitative meta-analysis, subgroups of outcomes were classified into general cognitive function (G-CF), attention and memory (A&M), and executive function (EF). Results : Nine RCTs were analyzed. The total number of participants was 271 (140 in the experimental group). The effect size (Cohen's d) was estimated using a random effects model. The effect sizes of the outcome subgroups of were as follows: small to medium for G-CF (d=0.422; 95% CI: 0.101~0.742; p=0.010), small for A&M (d=0.249; 95% CI: -0.107~0.605; p=0.170), and medium for EF (d=0.666; 95% CI: 0.136~1.195; p=0.014). Conclusion : Considering the various stimuli provided by the virtual environment and the results from available research, virtual reality should be applied to interventions for integrated cognitive functions. In addition, it would be appropriate to be used as an additional intervention to traditional cognitive rehabilitation for stroke.

Since the early 20th century, along with the interest and development of alternative psychotherapy, the field of art therapy has also been developed and expanded. In particular, the recent development of technology and the untact era brought about by the COVID-19 Pandemic is accelerating the development of new digital art therapy contents. Among them, the hot interest in virtual reality is raising expectations and questions about the effectiveness of psychotherapy given by new media beyond traditional art therapy. In this study, the characteristics of VRAT (Virtual Reality Art Therapy) content therapeutic factors were investigated through qualitative literature analysis based on the conceptual framework and therapeutic components of ETC (Expressive Therapies Continumm), an integrated art therapy theory. As a result of the study, VRAT contents showed mostly therapeutic factors in the left hemisphere that triggered the user's dynamic, perceptual, and cognitive factors, and the therapeutic factors in the right hemisphere, which focused on sensory, emotional, and symbolic factors, were relatively few. The reason seems to be due to the nature of the experimental stage, the absence of active intervention by the therapist and long-term session composition, and the fear, clumsiness, and unfamiliarity of users about VRAT in addition to the characteristics and technical limitations of the VRAT medium. The limitations of the study include the small number of documents to be analyzed and the insufficient form of current VRAT to be called art therapy. It is expected that the characteristics of the therapeutic factors of VRAT content media and environment derived as a result of this study will be usefully used for the appropriate development of VRAT content in the future.

Attention Deficit Hyperactivity Disorder(ADHD) is a childhood syndrome characterized by short attention span. impulsiveness, and hyperactivity, which often leadㄴ to learning disabilities and various behavioral problems. For the treatment of ADHD, medication and cognitive-behavior therapy is applied in recent yearn Although psycho-stimulant medication has been widely used for many rears. current findings suggest that, as the sole treatment for ADHD, it is an inadequate form of intervention in that parents don't want their child to use drug and the effects are limited to the period in which the drugs are physiologically active. On the other hand, EEG biofeedback treatment studies for ADHD have reported promising results not only in significant reductions in hyperactive, inattentive, and disruptive behaviors, but also improvements in academic performance and IQ scores. However it is too boring for children to finish the whole treatment. The recent increase in computer usage in medicine and rehabilitation has changed the way health care is delivered. Virtual Reality technology provides specific stimuli that can be used in removing distractions and providing environments that get the subjects'attention and increasing their ability to concentrate. VR technology can hold a patient's attention for a longer period of time than other methods can, because VR is immersive, interactive and imaginal. Based on these aspects, we developed Attention Enhancement System (AES) using VR technology, EEG biofeedback, and cognitive training method for enhancing attention and made a clinical trial to people who have attention difficulty and behavioral problems.

Objective: The purpose of this study was to evaluate the effect of virtual reality (VR)-based core stabilization exercise on upper extremity function, postural control, and depression among persons with stroke with hemiplegia. Design: Randomized controlled trial. Methods: This study was conducted with the inclusion of 24 participants and were randomly assigned to either the VR-based trunk stability exercise group (n=12) or control group (n=12). The VR-based trunk stability exercise group performed core stabilization exercises in a VR environment for 30 minutes. Meanwhile, the control group conducted general core stabilization exercises for 30 minutes. The participants trained 3 times a week for 4 weeks. The manual functional test (MFT), Box and Block Test (BBT), Berg Balance Scale (BBS), Trunk Impairment Scale (TIS), the Geriatric Depression Scale (GDS) were used to assess all participants before and after the intervention. Results: The VR-based core stabilization exercise group had a significant improvement in upper extremity function (MFT, BBT) and postural control (BBS) compared with the control group (p<0.05). The VR-based core stabilization exercise showed a significant difference after intervention in the TIS and GDS scores (p<0.05), but they did not significantly differ between the two groups. Conclusions: The result showed that VR-based core stabilization exercise can be effective in improving upper extremity function and postural control among patients with stroke more than the sole application of general physical therapy.

Purpose : This study systematically reviewed occupational therapy programs for upper extremity functions in subacute patients implemented over the last decade at home and abroad to utilize the findings as the basis for intervention protocols. Methods : This study was conducted with domestic and foreign randomized controlled experimental studies published from January 2013 to May 2023. Acute or subacute, CVA or stroke, upper extremity function, and program or therapy were used as search keywords in the search databases Scopus, PubMed, Riss, and DBpia. A total of 3,723 documents were retrieved, and 1,007 duplicate papers were excluded. In addition, 2,640 papers that did not meet the inclusion and exclusion criteria were excluded by the researcher examining the titles and abstracts. Thereafter, the full texts were checked. Consequently, 67 documents were excluded, and nine documents were finally used for analysis. Results : Due to the evaluation of the quality of the documents of nine studies, five items were rated "low," and two items were rated "unclear" in many studies. Males predominated the genders, and infarction predominated the types. The average age was over 50 but under 60 years, and the number of days after onset was predominantly fewer than one month. Occupational therapy programs were classified into mental programs, mirror therapy, music programs, and virtual reality programs, and virtual reality programs were frequently used. The intervention periods were predominantly 15-30 sessions for less than 30 minutes, and the Fugl-Meyer assessment-upper extremity was predominantly applied as an evaluation tool. Conclusion : This study is significant because it attempted to present the direction of intervention protocols for upper extremity functions in subacute stroke patients in clinical settings. Studies should be conducted with an expanded scope for a literature review.

The purpose of this study was to verify the clinical usefulness of the virtual reality rehabilitation system which Academic-Industrial cooperation develop through clinical experiment for recovering the functional abilities in stroke. For this purpose, 24 Stroke(hemorrhage13, infarction11)participated in a clinical experiment. They were randomly assigned to the virtual reality rehabilitation system group(n=13) and conventional rehabilitation training(Activities of daily living, cognition training, motor control) group(n=11). All participant were evaluated with three standardized assessment tools(Functional Independent Measure; FIM, Mini-Mental State Examination for Korean; MMSE-K, Self-esteem scale) before and after the planned intervention sessions. All participant were intensively carried out for 8weeks, 3times a week. The results were as follows. The experimental group showed significant improvements for Activities of daily living, basic cognitive abilities and self-esteem related with life satisfaction after the interventions(p<.05). There were no significant differences between two groups for all assessment tool after interventions. Because of this experimental results, the virtual reality rehabilitation system showed the clinical utility for recovering the function in stroke. Further studies are needed to verify the clinical usefulness on the improvement of various functions in brain injury and dementia.
