Eye Movement Desensitization & Reprocessing. It can be done by looking left and right, hearing sounds in alternate ears left and right, crossing your arms and tapping your hands on opposite arms, or patting someone's legs left and right to help them. The idea is to stimulate the left and right hemispheres of the brain alternately while dealing with the trauma. I'm thinking it helps the emotional side of the brain and the logical side of the brain talk. You can read up on it on the net easily enough, but it's best that a therapist help adminster it for best results.
I heard that people in the 9/11 attack used EMDR with good results. I used it for getting past a rape and another invasive trauma. EMDR is the therapy that finally helped.
