Purpose: The aims of this systematic review were to identify the study protocol of Virtual Reality Therapy (VRT) andreview the effect of VRT among patients with Post-Traumatic Stress Disorder (PTSD).
Methods: This review followedthe guideline of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A systematicliterature search was conducted using 12 electronic databases including gray literature with no limit of publication year. Search terms included relevant terms regarding ¡°PTSD¡±, ¡°trauma¡±, and ¡°VRT¡±. Among 265 studies extracted throughPRISMA, 20 studies were selected and evaluated for quality assessment using the Risk of Bias tool of Cochrane¡¯scollaboration.
Results: The majority of the literature focused on combat veterans and war situations (95%).Usually,each session usually took 60~120 minutes of VRT in 10~20 sessions for 5~10 weeks. The VRT equipment andcontents were individually designed considering patients¡¯ traumatic experiences. Most of the studies reported thepositive effects associated to reduced levels of PTSD (80%) and related symptoms, such as, depression (45%) andanxiety (25%).
Conclusion: Based on our findings, further studies are required to evaluate VRT in people with PTSD,after improving study design and standardizing protocols.
