Efficacy of end-to-end digitizited eye movement therapy for trauma desensitization, on Savyn’s app for treating PTSD symptoms

One of ten Canadians will experience trauma at least once in their lives and will develop post-traumatic stress disorder (PTSD). Many people cannot access PTSD care because of the high cost, long-waiting time, stigma and other barriers etc. Amygdala (deep brain) is important to traumatic emotions and memories. One way to access these memories is to use bi-lateral eye movements. Eye Movement Desensitization & Reprocessing (EMDR) is a well-established treatment for PTSD. Savyn’s app is based on some aspects of EMDR so more people who face barriers to accessing PTSD mental health support can have better access.
This is a research project to determine the efficacy of Savyn’s app in treating PTSD patients and to determine if it improves their PTSD symptoms The study will benefit Savyn in providing insight into how well PTSD symptoms are reduced, therefore providing evidence of benefit for trauma survivors to heal and feel better.
