The elderly people with advancing years have many problems such as the decline of the proprioceptive, visual & vestibular function and muscle weakness. Furthermore the decrease of the reflex which influences the balance ability in sudden change of the movement could cause the falls. The difficulty of the balance caused by the fear releated to the fall aggravates the Falls Efficacy and causes a lot of the disability of the independent activities of daily living. The purpose of this study was the effect of a Virtual Reality Program on Static Balance control and Fall efficacy of Elderly people. 14 elderly people(subjects) who were ≥65years of age partiripated in this study and they were divided into VR(Virtual Reality) group(n=7) and Control group (n=7). VR group took the general physical therapy & IREX and only the general physical therapy was carried out in the control group. VR group of intervention was carried out for 30min. total 8times. They were evaluated by BIO-Rescue, Fall Efficacy Scale before and after treatment. The Static Balance control and Fall efficacy were assessed by Bio-Rescue & Falls Efficacy Scale. The analysis of the resulf was assessed by Wilcoxon signed test & Mann-Whitney U test. The result showed that the static balance of VR group with the open eyes was improved in a static balance test and range of the movement was increased in limited of stability. And Falls Efficacy was also efficacious. IREX was effective to static balance control and Falls Efficacy of the elderly When we think about these effects, various treatments and objective assessments using VR program will be needed for the elderly

Introduction : This study reviews the main areas of cognitive rehabilitation including executive dysfunction, memory dysfunction, perceptual dysfunction, attention deficit, and dysfunctions in activities of daily living in order to apply to the adaptation of occupational therapy. Body : Cognition programs based on the virtual reality are being used not only to evaluate but to train the overall components of human's cognition. Because the cognitive program is concentrating on the real environment, it is known to bring a remarkable transitional effect to the actual environment, compared to the basic computer-based evaluation and training. Applying virtual reality to the rehabilitation program can develop and advance the high technology and can result in a major effect on the innovative treatment technology. Conclusions : In this process, virtual reality is expected to be researched more in the near future. Particularly in the cognitive realm, it is imperative for researchers to pay attention to the improved transitional effect of the virtual reality toward the actual environment, rather than the already existing method of evaluations. Therefore, application of the virtual reality for the cognitive training should be researched for various types of subjects in the diverse aspects of congnitive function. Application of the virtual reality in the cognitive function has its unlimited potential, thus the rehabilitation program integrated with not only evaluation but training and education is expected extensively in the future.

Age related decrease of muscle strength, balance, and gait abilities bring about physical inactivity in the elderly. Virtual reality (VR) training has been used successfully to rehabilitate functional balance and mobility in elderly subjects. This study was aimed at determining the effect of VR-based exercise programs by using a video game on the muscle strength, balance, and gait abilities in the elderly. 48 old people were randomly divided into two groups; VR-group (men: 11, women: 14, age: 68.42yrs) and control group (men: 10, women: 13, age: 67.58yrs). VR-group performed an exercise program twice a week for 8 weeks and control group had no intervention. The VR-based exercise program was composed of warm up(10 mins), VR-program(40 mins), and cool down(10mins). It was performed by playstation eyetoy play that provided visual and auditory feedback as well as movements of the upper and lower extremities. Muscle strengths of the knee and ankle were measured using manual muscle tester. Static balance was estimated using computerized posturography. Dynamic balance was measured by Timed up and go test (TUG), Functional reach test (FRT). 10m walk test and 6-min walk test were used to assess gait abilities. After the completion of the VR-exercise program, muscle strength, balance, and gait abilities were improved significantly (p<0.05). In conclusion, the VR-based exercise program showed improvement on the muscle strength, balance, and gait ability in the elderly. This exercise program is both effective and interesting for this age group.

우리나라의 고령화 속도는 세계에서 가장 빠르며 2000년 총인구에서 65세 이상 인구의 비중이 7.3%로 증가되고 있다. 우리나라는 고령친화제품에 대한 인식과 제품이 점차 늘고 있지만 아직까지는 초보단계에 불과하다. 그러나 노인의 건강 유지 및 여가생활을 위한 고령친화제품의 수요가 꾸준히 증가하는 추세이다. 최근 소프트웨어기술의 발전으로 인하여 3D 가상현실구현이 가능해짐에 따라 실내의 한정된 공간에서 운동을 즐기며 건강을 유지할 수 있는 용품 즉, 기존의 단순한 재활치료 접근방식에서 시공의 제약을 받지 않는 가상현실로 구현된 제품들이 출시되고 있다. 이를 이용하여 Type I muscle 강화를 위한 입체구동 Balance 기기를 상용화 한다면 고령층의 여가활동과 동시에 운동, 치료를 병행할 수 있을 것이다. 본 고에서는 Type I muscle 강화를 위한 Balance기기에 대해 알아보고 가상현실과의 접목을 위한 산업전반의 동향을 파악해본다.

노화가 시작되면 체력이 저하되어 면역기능이 떨어져 쉽게 병에 걸리고 환경에 대한 적응력이 떨어진다. 특히 60세 이상이 되면 근육 양과 근력이 급격히 가속화되어 신체적으로 약화되기 시작한다. 노화는 자연스럽게 진행되지만 꾸준한 운동을 통해 근력 저하 속도를 늦출 수 있다. 근력 증강을 위한 다양한 기기 개발에도 불구하고 노인들이 사용하는데 어려움이 있다. 특히 노인 신체적 특성에 맞는 운동기기 개발이 절실하며, 노인의 흥미를 유발시켜 자발적 참여를 유도하는 환경이 제공되어야 한다. 가상현실 기술은 실재하지 않거나 먼 거리에 있는 환경을 가상세계로 생성시켜서, 인간의 오감을 각종 인터페이스 장치를 통해 신호를 전달하여 가상의 현실 환경에 실재하고 있다고 느끼도록 만들어 주고, 가상세계와 상호작용을 통해 의료 진단, 치료, 재활 등에 유용한 도구 및 환경을 제공한다. 이러한 가상현실 기술의 특성 때문에 노인의 운동 참여와 운동 효과를 극대화 할 수 있다. 본 논문에서는 근력의 특성을 분석하고 노화와 근력과의 관계를 조사하고, 상지근력 증강 운동기와 해당 가상현실 컨텐츠 그리고 관련 컨텐츠 개발 동향에 대해 제시하고자 한다.

Objective : The purpose of this study was to investigate the effect of virtual reality program on fall efficacy and activities of daily living(ADL) for patients with stroke. Method : Twenty stroke patients were participated voluntarily and were assigned randomly into the control and the experimental groups. Both control and experimental groups were given same basic rehabilitation treatment while only the experimental group was given virtual reality program. The fall efficacy of both groups was assessed using fall efficacy scale(FES) and ADL performance ability was assessed by functional independence measure(FIM). Result : Fall efficacy and ADL performance ability showed a statistically meaningful difference for both experimental and control groups(p< .05), the fall efficacy and ADL performance ability of the experimental group improved meaningfully in a statistical way than that of the control group(p<. 05). Conclusion : It was found that carrying out virtual reality program with occupational therapy has an effect on fall efficacy and ADL performance ability of patients with stroke. Therefore, virtual reality program can be a way of treatment for patients with stroke to improve their fall efficacy and ADL performance ability, and the program can also be applied in clinics as well as occupational therapy.

Objective : This study was the influence of the training program using virtual reality on eye-hand coordination in children with developmental disordered. Methods : Six children(5 males, 1 female)with developmental disordered were recruited and randomly assigned to the control group(n=3) and the experimental group(n=3). Three children in the control group performed a fifty minutes of SI program ten times for ten weeks. In the experimental group, the other three children underwent a fifty minutes of SI program and virtual reality game. K-DTVP-2(Korean Developmental Test of Visual Perception)was used to measure the eye-hand coordination. Results : After a ten weeks of training program, there were significant differences in the eye-hand coordination in the experimental group. Conclusion : The training program using virtual reality games influenced for improving at the eye-hand coordination in children with developmental disordered.
