The purpose of this study is to review the effect of previous research data with virtual reality-based Physical Activity Therapy Programs(PATPs) in adult on the physical fitness factors. Research articles were retrieved from 2008 to 2021 with the Research Information Sharing Service(RISS) and Pubmed database. The main search terms were 'care', 'therapy', 'healing', 'exercise' or 'physical activity', and 'virtual reality'. The criteria for selecting articles of this study were the originality, duplication, Randomized controlled trial(RCT) experiment and subject. Finally, 18 papers were selected among 318 articles, which were excluded if any of the criteria was not satisfied. Most of papers(15) were conducted in the last 5 years, because of the high interest due to the development of virtual reality implementation technology and COVID-19 pandemic. The participants were mainly patients(8), and the types of diseases were stroke(2). The physical fitness factors were mostly balance ability(7), muscle strength(7), and range of motion(6). All the physical fitness factors were significantly improved after PATPs. However, 11 studies were conducted for less than 4 weeks, including 6 studies were performed a bout of acute exercise. Also, 14 studies did not clearly present the intensity of PATPs. In addition, there were 9 studies, that simply applied games without specialized programs. In conclusion, it seems that virtual reality-based PATPs have a positive effect on physical fitness factors. However, VR-based PATPs should be specialized and developed in order to verify their effectiveness for the further research.

Virtual Reality (VR) is a new technology that enables humans to communicate with a computer, It allows the user to see, hear, fuel and interact in a three-dimensional virtual world created graphically. Virtual Reality Therapy (VRT), based on this sophisticated technology, has been recently used in the treatment of subjects diagnosed with acrophobia. Acrophobia is a disorder that is characterized by marked anxiety upon exposure to heights, avoidance of heights, and a resulting impairment in functioning. Conventional virtual reality systems for the treatment of acrophobia have limitations, such as overly expensive devices or somewhat unrealistic graphic scenes. The goal of this study is to develop an inexpensive and more realistic virtual environment in which to perform an exposure therapy fur acrophobia. It runs on a personal computer, and a virtual scene ova bunge-jump tower in the middle of a large city. The virtual scenario includes an open tin surrounded by props beside a tower, which allows the patient to feel a sense of heights. The effectiveness of the VR environment was evaluated through the clinical treatment of a subject who was suffering from the fear of heights. Based on pre- and post- questionnaires and subjective comments from the subject. This virtual reality environment proved to be an effective and realistic tool fur the treatment of acrophobia.

20세기 초부터 대안적 심리치료의 관심과 발전과 더불어 예술치료의 영역도 발전, 확장되어 가고 있다. 특히 근래 들어 기술의 발전과 코로나 사태(Covid 19 Pandemic)가 불러온 언택트(Untact) 시대는 디지털 예술치료 콘텐츠에 대한 개발을 가속화 하고 있다. 그 중 가상현실(Virtual Reality)에 대한 높은 관심은 전통적 예술치료를 넘어서는 새로운 매체의 치료적 효과성에 대한 기대와 의문을 동시에 불러오고 있다. 이 연구에서는 통합 미술치료이론인 ETC(Expressive Therapies Continumm)의 개념 틀과 치료적 구성요소에 기반한 체계적 문헌분석을 통해 가상현실 미술치료(VRAT:Virtual Reality Art Therapy) 콘텐츠의 치료적 요인의 특성을 알아보고자 하였다. 연구결과로는 VRAT 콘텐츠는 사용자의 동적, 지각적, 인지적 요인을 촉발하는 좌반구 대상의 치료적 요인이 주로 나타났고 감각적, 정서적, 상징적 요소에 치중된 우반구 대상의 치료적 요인은 상대적으로 드물게 나타났다. 그 이유로는 VRAT 매체의 특성 및 기술적 한계 외에도 실험적 단계의 특성상 치료사의 적극적 개입과 장기적 세션 구성의 부재, 사용자들의 VRAT 에 대한 두려움과 서툼, 낯섦 등에 기인한 것으로 보인다. 연구의 한계로는 적은 수의 분석 대상 문헌과 미술치료라고 하기엔 미비한 현 VRAT 의 형식이며 본 연구의 결과로서 도출된 VRAT 콘텐츠 매체와 환경에 기인한 치료 요인의 특징과 가능성이 향후 VRAT 콘텐츠의 적절한 개발에 유용하게 쓰이길 기대한다.
