eye movement desensitization and reprocessing

Eye movement desensitization and reprocessing (EMDR) is a form of psychotherapy that is controversial within the psychological community. It was devised by Francine Shapiro in 1987 and originally designed to alleviate the distress associated with traumatic memories such as post-traumatic stress disorder (PTSD). EMDR involves focusing on traumatic memories in a manner similar to exposure therapy while engaging in side-to-side eye movements or other forms of bilateral stimulation. It is also used for some other psychological conditions. EMDR is recommended for the treatment of PTSD by various government and medical bodies citing varying levels of evidence, including the World Health Organization, the UK National Institute for Health and Care Excellence, the Australian National Health and Medical Research Council, and the US Departments of Veteran Affairs and Defense. Treatment guidelines note EMDR effectiveness is statistically the same as trauma-focused behavioral therapy, and the Australian National Health and Medical Research Council notes that this may be due to including most of the core elements of CBT. There is debate about how the therapy works and whether it is more effective than other established treatments. The eye movements have been criticized as having no scientific basis. The founder promoted the therapy for the treatment of PTSD, and proponents employed untestable hypotheses to explain negative results in controlled studies. EMDR has been characterized as a pseudoscientific purple hat therapy (i.e., only as effective as its underlying therapeutic methods without any contribution from its distinctive add-ons). The US National Institute of Medicine found insufficient evidence to recommend it as of 2008.
