Criticism: as above, reorganization for consistency
History: Rosen doesn't say anything of the sort in the linked source, and Grimley is an NLP guy himself. We should definitely not source a claim that something is linked to a pseudoscience exclusively to proponents of that pseudoscience.

Line 7:
EMDR involves talking about traumatic memories 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[[United States Department of Veterans Affairs|Veterans Affairs]] and [[United States Department of Defense|Defense]]. The [[American Psychological Association]] does not endorse EMDR as a first-line treatment, but indicates that it is probably effective for treating adult PTSD.
 
Systematic analyses published since 20202013 suggestgenerally indicate that EMDR treatment efficacy for adults with PTSD is equivalent to trauma-focused cognitive and behavioral therapies (TF-CBT), such as [[Prolongedprolonged exposure therapy]] (PE) and [[Cognitivecognitive Processingprocessing Therapytherapy]] (CPT). However, bilateral stimulation does not contribute substantially, if at all, to treatment effectiveness. The predominant therapeutic factors in EMDR and TF-CBT are [[Exposure therapy|exposure]] and various components of [[cognitive-behavioral therapy]].
 
Because eye movements and other bilateral stimulation techniques do not uniquely contribute to EMDR treatment efficacy, EMDR has been characterized as a [[purple hat therapy]], i.e., its effectiveness is due to the same therapeutic methods found in other evidence-based psychotherapies for PTSD, namely exposure therapy and CBT techniques, without any contribution from its distinctive add-ons.
 
== History ==
EMDR was invented by [[Francine Shapiro]] in 1987. In a workshop, Shapiro related how the idea of the therapy came to her while she was taking a walk in the woods, and discerned she had been able to cope better with disturbing thoughts when also experiencing [[saccadic]] eye movements.<ref name=walk>{{cite journal |vauthors=Rosen GM |title=On the origin of eye movement desensitization |journal=J Behav Ther Exp Psychiatry |volume=26 |issue=2 |pages=121–2 |date=June 1995 |pmid=7593684 |doi=10.1016/0005-7916(95)00014-q |url=}}</ref> Psychologist Gerald Rosen has expressed doubt about this description, saying that people are normally not aware of this type of eye movement.<ref name=walk/>

==Possible mechanisms==
===Training===
===Incomplete processing of experiences in trauma===
Shapiro was criticized for repeatedly increasing the length and expense of training and certification, allegedly in response to the results of controlled trials that cast doubt on EMDR's efficacy.<ref name="1999 Skeptic">{{cite journal|title=Eye Movement Magic: Eye Movement Desensitization and Reprocessing|journal=Skeptic|volume=7|issue=4|year=1999| vauthors = Rosen GM, Mcnally RJ, Lilienfeld SO | author-link3=Scott Lilienfeld | url=http://www.skeptic.com/eskeptic/14-05-21/#feature}}</ref><ref name="Herbert">{{cite journal | vauthors = Herbert JD, Lilienfeld SO, Lohr JM, Montgomery RW, O'Donohue WT, Rosen GM, Tolin DF | title = Science and pseudoscience in the development of eye movement desensitization and reprocessing: implications for clinical psychology | journal = Clinical Psychology Review | volume = 20 | issue = 8 | pages = 945–971 | date = November 2000 | pmid = 11098395 | doi = 10.1016/s0272-7358(99)00017-3 | s2cid = 14519988 }}</ref> This included requiring the completion of an EMDR training program in order to be qualified to administer EMDR properly after researchers using the initial written instructions found no difference between no-eye-movement control groups and EMDR-as-written experimental groups.

Many proposals of EMDR efficacy share an assumption that, as Shapiro posited, when a traumatic or very negative event occurs, information processing of the experience in memory may be incomplete. The trauma causes a disruption of normal adaptive information processing, which results in unprocessed information being dysfunctionally held in memory networks.<ref>{{cite journal | vauthors = Solomon RM, Shapiro F | s2cid=7109228 |title=EMDR and the Adaptive Information Processing ModelPotential Mechanisms of Change |journal=Journal of EMDR Practice and Research |date=November 2008 |volume=2 |issue=4 |pages=315–325 |doi=10.1891/1933-3196.2.4.315 }}</ref> According to the 2013 World Health Organization practice guideline: "This therapy [EMDR] is based on the idea that negative thoughts, feelings and behaviours are the result of unprocessed memories."<ref name="WHO 2013" /> This proposed mechanism has no known scientific basis.<ref name=non/>

EMDR has been characterized as [[pseudoscience]], because the underlying theory and primary therapeutic mechanism are [[Falsifiability|unfalsifiable]] and non-scientific.

EMDR proponents have come up with ad hoc hypotheses to explain away unfavorable results that do not support its theory, which is one of the hallmark indicators of a pseudoscience...

Investigation into EMDR has been characterised by poor-quality studies, rather than tightly-controlled trials that could justify or falsify the mechanisms that have been proposed to support it.

EMDR has been characterised as a modern-day [[mesmerism]], as the therapies have striking resemblances, from the sole inventor who devises the system while out walking, to the large business empire built on exaggerated claims.

==Possible mechanisms==
===Incomplete processing of experiences in trauma===
Many proposals of EMDR efficacy share an assumption that, as Shapiro posited, when a traumatic or very negative event occurs, information processing of the experience in memory may be incomplete. The trauma causes a disruption of normal adaptive information processing, which results in unprocessed information being dysfunctionally held in memory networks.<ref>{{cite journal | vauthors = Solomon RM, Shapiro F | s2cid=7109228 |title=EMDR and the Adaptive Information Processing ModelPotential Mechanisms of Change |journal=Journal of EMDR Practice and Research |date=November 2008 |volume=2 |issue=4 |pages=315–325 |doi=10.1891/1933-3196.2.4.315 }}</ref> According to the 2013 World Health Organization practice guideline: "This therapy [EMDR] is based on the idea that negative thoughts, feelings and behaviours are the result of unprocessed memories."<ref name="WHO 2013" /> This proposed mechanism has no known scientific basis.<ref name=non/>
 
EMDR adds a number of non-scientifictechniques practicesthat do not appear to [[exposurecontribute to therapeutic effectiveness, e.g., bilateral therapy]]stimulation.<ref name="non">{{cite book |page=292 |vauthors= Lohr JM, Gist R, Deacon B, Devilly GJ, Varker T |chapter=Chapter 10: Science- and Non-Science-Based Treatments for Trauma-Related Stress Disorders |publisher=Routledge |veditors=Lilienfeld SO, Lynn SJ, Lohr JM |title=Science and Pseudoscience in Clinical Psychology |edition=2nd |year=2015 |isbn=9781462517893|quote="...eye movements and other bilateral stimulation techniques appear to be unnecessary and do not uniquely contribute to clinical outcomes.

Moreover, its theoretical model and purported primary active therapeutic ingredient are not scientifically supported."}}</ref> EMDR is classified as one of the "power therapies" alongside [[thought field therapy]], [[Emotional Freedom Techniques]] and others{{snd}}so called because these therapies are marketed as being superior to established therapies which preceded them.<ref name=ros2012>{{cite book |vauthors=Rosquist J |isbn=9781136915772 |publisher=Routledge |year=2012 |title=Exposure Treatments for Anxiety Disorders: A Practitioner's Guide to Concepts, Methods, and Evidence-Based Practice |page=92}}</ref>
===Other mechanisms===
Several other possible mechanisms have been proposed:
* EMDR may impact working memory.<ref>{{cite journal | vauthors = van den Hout MA, Engelhard IM, Beetsma D, Slofstra C, Hornsveld H, Houtveen J, Leer A | title = EMDR and mindfulness.

EMDR has been characterized as [[pseudoscience]], because the underlying theory and primary therapeutic mechanism are [[Falsifiability|unfalsifiable]] and non-scientific.

InvestigationFurthermore, Novella argues that investigation into EMDR has been characterised by poor-quality studies, rather than tightly-controlled trials that could justify or falsify the mechanisms that have been proposed to support it. Novella writes that the research quantity nevertheless means that EMDR has claimed a place among accepted treatments and is "not likely going away anytime soon, even though it is a house of cardcards built on nothing".<ref name="f445">{{cite web | title=EMDR Is Still Dubious | publisher=Science-Based Medicine | date=23 October 2024 | url=https://sciencebasedmedicine.org/emdr-is-still-dubious/ | vauthors=Novella S}}</ref>

== History ==
EMDR was invented by [[Francine Shapiro]] in 1987.
 
EMDR has been characterised as a modern-day [[mesmerism]], as the therapies have striking resemblances, from the sole inventor who devises the system while out walking, to the large business empire built on exaggerated claims. In the case of EMDR, these have included the suggestions that EMDR could drain violence from society and be useful in treating [[cancer]] and [[HIV/AIDS]].<ref name="tsep">{{cite book |title=[[The Skeptic Encyclopedia of Pseudoscience]] |vauthors=Rosen GM, McNally RJ, Lilienfield SO |publisher=Bloomsbury |year=2002 |isbn=978-1-57607-653-8 |veditors=Shermer M, Linse P |volume=1 |pages=321–326 |chapter=EMDR: Eye Movement Desensitization and Reprocessing}}</ref> Psychology historian Luis Cordón has compared the popularity of EMDR to that of other cult-like pseudosciences, [[facilitated communication]] and [[thought field therapy]].<ref name=cordon>{{cite book |veditors=Cordón LA |year=2005 |title=Popular psychology: An encyclopedia |publisher=Greenwood Press |chapter=Eye movement desensitization and reprocessing |pages=81–82}}</ref>
