I had no training in EMDR, but I knew a little about it. First introduced in the US back in the mid-1990s, it is a technique that charges our memory system with a dual task involving attentional eye movements. The therapist moves a finger back and forth in front of the patient’s face, asking them to follow the movement while remembering and describing traumatic images and the feelings they evoke. Today, it has become the treatment of choice for people with PTSD flashbacks, and numerous studies conclude that the results can be impressive.5
