EMDR – Client Handout What is EMDR? The mind can often heal itself naturally, in the same way as the body does. Much of this natural coping mechanism occurs during sleep, particularly during rapid eye movement (REM) sleep. Francine Shapiro developed Eye Movement Desensitisation and Reprocessing (EMDR) in 1987, utilising this natural process in order to successfully treat Post-traumatic Stress Disorder (PTSD). Since then, EMDR has been used to effectively treat a wide range of mental health problems.
