EMDR therapy uses bilateral stimulation, typically guided eye movements, to help you process traumatic memories without reliving them in detail. The approach addresses PTSD, anxiety, phobias, and grief tied to disturbing life experiences. If you want to process the trauma, not just talk about it, see EMDR sessions with a clinician on our team for California availability.
What is EMDR therapy?
EMDR stands for Eye Movement Desensitization and Reprocessing. It is a psychotherapy approach developed by Francine Shapiro in 1987. Per the EMDR International Association (EMDRIA), EMDR is recognized as effective for post-traumatic stress disorder. Use this explainer to understand the method before you decide whether it fits your situation.
EMDR is not conventional talk therapy. A trained EMDR therapist guides you through brief sets of bilateral stimulation while you hold a target memory in mind. The goal is memory reprocessing: the disturbing memory loses its emotional charge so it no longer drives the same symptoms.
The APA, the VA and DoD, and the World Health Organization all recognize EMDR as an evidence-based treatment approach. That level of clinical endorsement is uncommon for a psychotherapy modality outside of CBT.
How does EMDR work?
EMDR works through bilateral stimulation, typically guided side-to-side eye movements. According to Shapiro's 2014 paper in PubMed Central, the Adaptive Information Processing (AIP) model explains this mechanism. Apply the AIP framework to your situation: unprocessed traumatic memories stay "stuck" in their raw, distressing form, and bilateral stimulation gives the nervous system a way to move through them.
The AIP model proposes that unprocessed memories keep their original emotional charge. Bilateral tones, hand tapping, or guided eye movements engage both hemispheres of the brain. That dual attention appears to loosen the grip of the memory on the nervous system.
Some researchers debate which specific component of bilateral stimulation is the active ingredient. The eye-movement-versus-tapping question is still being studied in the literature. The clinical endorsements and the outcome data support the overall approach regardless of that unresolved question.
What are the 8 phases of EMDR?
Per the EMDR Institute, EMDR therapy follows an 8-phase protocol where each phase serves a specific purpose. Ask your clinician which phase you are currently in at any session. A trained EMDR therapist moves through all 8 phases, though not always in a single session.
-
History taking (phase 1). Your clinician takes a full history and identifies target memories. They map out the experiences most likely driving your current symptoms.
-
Preparation (phase 2). Your clinician teaches you stabilization and resourcing skills before any reprocessing begins. This work builds the safety scaffolding you draw on between sessions.
-
Assessment (phase 3). Your clinician identifies the target memory, the negative cognition, and the positive cognition you want instead. A baseline SUD scale score tracks your progress.
-
Desensitization (phase 4). You hold the target memory while your clinician guides sets of bilateral stimulation. This is the core reprocessing phase.
-
Installation and body scan (phases 5 and 6). Your clinician helps you install the new positive cognition. Then you scan your body for any remaining tension, and residual sensations are reprocessed.
-
Closure and reevaluation (phases 7 and 8). Each session ends with structured closure so you leave in a stable state. The next session opens with reevaluation to confirm the processing held.
What does an EMDR session actually look like?
In an EMDR session, you hold a target memory in mind while your clinician runs brief sets of bilateral stimulation. Per APA's EMDR explainer, sessions typically run 60 to 90 minutes for active reprocessing phases. Plan to have time after a session, because processing can bring up strong emotions.
You are not required to narrate the event in detail. You hold the memory in mind and report what you notice after each set: a shift in the image, an emotion, or a body sensation. You can pause at any point.
The clinician uses the closure phase to return you to a stable state before the session ends.
What conditions does EMDR help with?
EMDR is most strongly recognized for PTSD and post-traumatic stress disorder. The EMDR Institute cites more than 40 controlled outcome studies on trauma-related presentations. Research also supports its use for anxiety, panic attacks, specific phobias, and grief. Evidence for depression as a standalone target is more mixed, so consult a trained clinician about your specific presentation.
Veterans and combat trauma survivors are among the most studied populations. Flashbacks, intrusive thoughts, nightmares, hypervigilance, and avoidance behaviors are the symptom cluster with the clearest evidence base.
What the research says about EMDR
The APA's EMDR resource page recognizes EMDR as an effective psychotherapy approach. The VA National Center for PTSD and the World Health Organization have done the same. Check EMDRIA's therapist locator to verify that your clinician has completed a recognized training program before you start.
Shapiro's 2014 PubMed Central review references more than 30 controlled outcome studies. EMDRIA and the EMDR Institute hold the credentialing standards for trained EMDR therapists. Clinicians who complete EMDRIA-approved training complete a structured program of supervised hours before practicing independently.
The clinical endorsements are specific to post-traumatic stress disorder as the primary application. Evidence for anxiety, depression, and phobias is promising but less settled than the trauma literature. A clinician describing EMDR as proven for every condition is overstating the current research base.
Who is EMDR not recommended for?
EMDR is not a good fit for every person or presentation. Per Cleveland Clinic's EMDR overview, active psychosis, acute psychiatric crisis, and severe untreated dissociation require modification or a delay before reprocessing begins. Ask a trained EMDR therapist about your specific history before starting any reprocessing work.
Certain presentations call for extended preparation before desensitization. If your nervous system dysregulation is high, your clinician may spend weeks in phase 2 building resourcing skills. A clinician skipping preparation and going straight to phase 4 is a common source of difficult EMDR experiences.
EMDR also requires the ability to tolerate brief exposure to distressing material. Some clients in acute crisis may need a higher level of care before starting. If you are in crisis, call or text 988 to reach the Suicide and Crisis Lifeline.
Frequently asked questions
Why is EMDR controversial?
EMDR is endorsed by the APA, the VA and DoD, the WHO, and EMDRIA, with more than 30 controlled outcome studies. The controversy centers on mechanism: researchers still debate whether the eye movements are the active ingredient. Training quality is also a factor, because poorly delivered EMDR from an undertrained clinician can cause distress. Seek a clinician with EMDRIA-approved training.
Will I cry during EMDR?
Emotional intensity during EMDR is common. Tears, anger, and body sensations are part of the reprocessing process. The protocol includes built-in stopping points, and every session closes with a structured closure phase before you leave. You can pause at any point. Not every session is emotionally intense; the experience varies by target memory and where you are in the 8-phase protocol.
How long does EMDR take to work, and how many sessions will I need?
Treatment length varies widely and depends on your history, trauma complexity, and baseline stabilization. It is based on your medical necessity, not a fixed count. Research on single-incident trauma has reported ranges of 6 to 12 sessions in some studies, while complex or developmental trauma typically requires a longer course. Any clinician quoting a specific fixed session count is overpromising.
Will I have to relive the trauma out loud?
You are not required to narrate the traumatic event in detail during EMDR. You hold the memory in mind and report what you notice: an image, an emotion, a body sensation, or a shift. The process moves through the memory rather than re-telling it, and you can stop at any point by signaling your clinician.
How do I find a trained EMDR therapist?
Look for a clinician who has completed an EMDRIA-approved training program. EMDRIA's therapist locator lists therapists by training level and location. If you are in California, see our EMDR therapy service page for session and insurance details.
