Military motion-based memory desensitization and reprocessing (3MDR): A novel treatment for PTSD?
Introduction: The dual task processing in eye movement desensitization and reprocessing (EMDR) has proven effective for the treatment of deployment related posttraumatic stress disorder. The procedure is typically performed in sedentary condition with imaginary exposure conditions. Therapeutic adherence is reported a problem in military populations compromising treatment efficacy. We aimed at designing a treatment procedure that preserved dual task processing principle, yet introduced new engagement by performing the desensitization during motion by to walking on a treadmill. Moreover, we aimed at exposure to real high-affect pictures of deployment setting. Our objective was to design a modified EMDR procedure for deployment related PTSD using motion based memory reprocessing with virtual reality. Method: We designed a treatment based on the 6 DoF motion base of the Computer Assisted Rehabilitation Environment (CAREN) facility. This adds to regular therapy physical (walking) elements, virtuality with visual (pictures/words with 180deg field of vision) and auditory (Dolby surround). Subjects walk a repetitive cycle while walking and viewing high affect pictures of deployment scenes. Dual task processing was maintained by an oscillating ball. Aspects of presence are adhered to, to maximize possible positive outcome. Results/Conclusions: The proof of concept will be presented with preliminary results on efficacy and therapeutic adherence.
