EMDR (Eye Movement Desensitization and Reprocessing) — a psychotherapy method developed by American psychologist Francine Shapiro in 1987. Originally created for treating Post-Traumatic Stress Disorder (PTSD) , the method's scope has since expanded significantly.
EMDR is based on the Adaptive Information Processing (AIP) model, according to which psychopathology arises from the incomplete processing of traumatic memories. The central element of the method is bilateral stimulation (BLS) — rhythmic eye movements, auditory tones, or tactile signals that alternately activate the right and left hemispheres of the brain.
EMDR is recognized by the World Health Organization (WHO, 2013) and the American Psychological Association (APA, 2004) as an evidence-based treatment for PTSD. It is included in the clinical guidelines of health ministries in more than 20 countries, including the United Kingdom (NICE), Australia , Israel , and the Netherlands .
The method was discovered by Francine Shapiro (1948–2019) — an American psychologist and research fellow at the Mental Research Institute in Palo Alto, California. In 1987, while walking through a park, Shapiro noticed that spontaneous rapid eye movements reduced the intensity of her own anxious thoughts. Intrigued by this observation, she began systematic research.
In 1989 , the Journal of Traumatic Stress published Shapiro's first scientific article, describing the effect of eye movements when working with traumatic memories in 22 participants. The method was originally called EMD (Eye Movement Desensitization) and was intended solely to reduce sensitivity to traumatic memories.
Further research revealed that in addition to desensitization, spontaneous cognitive reprocessing also occurred — clients not only stopped reacting acutely but also began to make new meaning of the trauma. In 1991 , the method received its modern name EMDR , incorporating the word "Reprocessing" into the acronym.
The theoretical foundation of EMDR is the Adaptive Information Processing model (AIP). According to this model, the brain has an innate information processing system that normally integrates new experiences into existing neural networks, extracting useful lessons and discarding unnecessary emotional components.
During intense stress or trauma, this system can become disrupted : the traumatic memory is stored in an unprocessed form — with original sensory images, bodily sensations, and emotional intensity. As a result, the event continues to be perceived as if it is happening "here and now," triggering corresponding reactions.
The goal of EMDR is to activate the natural processing of blocked traumatic material through bilateral stimulation, allowing the brain to complete what it could not complete at the moment of trauma.
Bilateral stimulation is the key technical element of EMDR. BLS refers to alternating stimulation of the right and left brain hemispheres, which can be delivered in three ways:
Visual BLS is the most commonly used — eye movements analogous to those that naturally occur during REM (rapid eye movement) sleep , when the brain processes daily experiences. This is one explanation for the method's effectiveness: BLS mimics a natural neurobiological mechanism.
Neuroimaging studies (fMRI, PET) show that EMDR therapy leads to:
Eye-tracking studies also show that bilateral stimulation reduces the vividness and emotional intensity of negative images in working memory — a phenomenon known as the "dual attention" effect.
The standard EMDR protocol consists of eight sequential phases. Importantly, contrary to popular belief, EMDR is not just "eye movements." It is a comprehensive psychotherapeutic system with a clear structure.
| Phase | Name | Content | Approximate Duration |
|---|---|---|---|
| 1 | History Taking | Assessment of readiness for EMDR, identification of traumatic memories, treatment planning | 1–2 sessions |
| 2 | Preparation | Teaching self-regulation techniques ("Safe Place," "Container"), building trust | 1–2 sessions |
| 3 | Assessment | Selecting the target memory, identifying negative and positive cognitions, measuring emotions using SUD and VoC scales | Part of a session |
| 4 | Desensitization | Core phase: reprocessing traumatic material using BLS until subjective distress drops to 0 | 1–several sessions |
| 5 | Installation | Strengthening the positive cognition with BLS until fully embraced (VoC = 7) | Part of a session |
| 6 | Body Scan | Checking for residual bodily tension associated with the memory | Part of a session |
| 7 | Closure | Stabilizing the client, providing guidance on possible between-session reactions | 5–10 minutes |
| 8 | Reevaluation | Checking the stability of results at the beginning of the next session | Start of next session |
The standard EMDR protocol involves working across three temporal directions (three-pronged protocol):
As of 2025, there have been more than 40 randomized controlled trials (RCTs) investigating EMDR's effectiveness. The first major RCT, conducted by Wilson et al. (1995) , showed significant reduction in PTSD symptoms after three 90-minute EMDR sessions in 80% of participants.
One of the most cited studies — van der Kolk et al. (2007) — compared EMDR with pharmacotherapy (fluoxetine/Prozac) and placebo. Results: EMDR showed significantly better outcomes in reducing PTSD and depression symptoms, and the effect was maintained at 6-month follow-up, unlike the medication group where symptoms returned after discontinuation.
Key meta-analysis findings:
A growing body of research supports the use of EMDR for:
EMDR therapy training is standardized internationally. The governing body is the EMDR International Association (EMDRIA, USA), which sets training and accreditation standards.
EMDR training is offered worldwide by accredited trainers certified through EMDRIA or EMDR Europe Association , as well as national EMDR associations across Asia, Latin America, and the Middle East.
The most debated question in the scientific community is whether bilateral stimulation is a necessary and specific component of the method or whether EMDR works through non-specific factors (exposure + cognitive reprocessing), similar to CBT.
Some studies (Davidson & Parker, 2001; Salkovskis, 2002) suggest that eye movements do not add effectiveness beyond exposure. However, more recent research (Lee & Cuijpers, 2013) and meta-analyses show that the BLS component provides an additional contribution to reducing the emotional vividness of memories compared to fixed-eye conditions.
Another subject of debate is speed of action . Although EMDR is often described as a "rapid method," complex trauma (C-PTSD) treatment may require many months of regular sessions, comparable in duration to other evidence-based approaches.
EMDR is considered a safe method when protocol is followed and the therapist is properly trained. Possible temporary reactions between sessions include:
These phenomena are considered a normal part of the reprocessing process , not a complication. The therapist teaches the client self-regulation techniques (Phase 2) precisely to minimize discomfort between sessions.
