Eye Movement Desensitization and Reprocessing (EMDR) was developed by Francine Shapiro about 25 years ago. Originally conceived as a way to reprocess trauma for PTSD,  it's focus is to support Adaptive Information Processing (AIP) of traumatic memories and events. It is considered a gold standard for trauma treatment. The rationale behind bilateral stimulation and EMDR is that the brain  holds negative self-beliefs in the neural memory networks that came from earlier traumatic  events, and that these negative beliefs from the past interfere in healthy living in the present. EMDR is a structured approach that can produce rapid results  that appear to "re-wire" the brain by transforming negative beliefs into more positive or neutral ones. I am certified in EMDR and active in an EMDR consultation group.
