EMDR is a psychotherapy technique used to treat trauma and other troubling life experiences. It was developed in 1987 when Dr. Francine Shapiro observed that eye movements seemed to reduce the intensity of disturbing thoughts. EMDR uses bilateral stimulation like eye movements or taps matched with recalling distressing memories, which helps reprocess the memories so they are no longer troubling. There are 8 phases of treatment where clients identify troubling memories and process them with sets of eye movements from the therapist until the distress level reduces. EMDR can often resolve trauma within a few sessions and has been shown to be an effective treatment for PTSD.
