EMDR, or Eye Movement Desensitization and Reprocessing, is a technique which is suggested by research to be helpful in addressing posttraumatic stress disorder, also known as PTSD. Essentially it involves having a client engage in saccadic (side to side) eye movements while holding in mind traumatic events. It appears to rapidly decrease distress associated with traumatic events.
I have been trained to the second level (the highest one goes before being considered for certification as a trainer) in EMDR and use it from time to time in my business.
