This research explores whether 3MDR was able to reduce traumatic stress symptoms in military veterans with Service-related PTSD.
Modular motion-assisted memory desensitisation and reconsolidation (3MDR) is a new treatment that aims to reduce cognitive avoidance and augment engagement with therapy. 3MDR is based on known therapeutic principles of virtual reality exposure therapy and eye movement desensitisation and reprocessing (EMDR), embedded in a novel context in which the patient walks on a treadmill whilst interacting with a series of self-selected images that are displayed on a large screen. Exposure by virtual reality, enhanced with walking, music and high affect pictures, eliminates cognitive avoidance during exposure and promotes presence. This is an important distinction between 3MDR and traditional trauma focused techniques which are sedentary; patients learn how to move through their avoidance by, literally, walking back into their trauma memory.
