In this chapter the potential for using new technologies (virtual reality) with the aim of treating Posttraumatic Stress Disorder (PTSD) is examined. We have developed a VR application (“EMMA's room” and “EMMA's world”) where the therapist and the patient can represent the experience suffered by the patient according to the specific therapeutic needs. The goal of the Emma's virtual environments is to work with emotions related to the participants' psychological problem. The specific emotions depend on the specific ways in which the problem is symbolized in each of the scenarios. EMMA tools are used to maximize the effect of these new strategies. EMMA is designed to help the person experience the emotions and experiences which he/she is going through, to touch them and feel them; in short, to accept them and to live with them from another perspective. In this work we present the EMMA environment and the clinical treatment protocol for PTSD in a case study.
