EMDR therapy is one of the most extensively researched and widely validated treatments for PTSD available. Endorsed by the American Psychological Association, the World Health Organization, and the Department of Veterans Affairs, EMDR has helped millions of trauma survivors process traumatic memories and achieve lasting recovery — often without requiring detailed verbal narration of the traumatic event.
What Is EMDR Therapy?
Eye Movement Desensitization and Reprocessing (EMDR) is a structured psychotherapy approach developed by Dr. Francine Shapiro in the late 1980s. It is based on the Adaptive Information Processing (AIP) model — the theory that traumatic memories become “stuck” in the nervous system when they cannot be processed normally, leaving them stored in a raw, fragmented form that continues to generate distress when activated. EMDR uses bilateral stimulation — typically guided eye movements, but sometimes tapping or auditory tones — to facilitate the brain’s natural processing of these stuck memories.
The effect of EMDR is not well understood at the neurological level, but the evidence for its effectiveness is substantial. Dozens of randomized controlled trials have demonstrated significant PTSD symptom reduction, and meta-analyses consistently rank EMDR alongside Cognitive Processing Therapy and Prolonged Exposure as the most effective PTSD treatments available. For a broader overview of where EMDR sits among available PTSD treatment approaches, see the treatment approaches overview page.
The Eight Phases of EMDR
EMDR follows a structured eight-phase protocol. Understanding this structure helps demystify what happens in EMDR sessions and what makes it different from conventional talk therapy.
Phase 1 — History-taking: The therapist takes a thorough trauma history, identifies specific memories that will be targeted, and assesses the client’s readiness for processing.
Phase 2 — Preparation: The client learns grounding and stabilization skills — including grounding techniques such as the safe place visualisation — that will be available throughout processing. This phase establishes the therapeutic relationship and ensures the client can tolerate the processing phases without becoming overwhelmed.
Phase 3 — Assessment: The specific target memory is activated: the image, the negative belief associated with it (e.g. “I am powerless”), the emotion, and the body sensation. A Subjective Units of Distress (SUDs) rating establishes a baseline.
Phases 4–7 — Desensitization, Installation, Body Scan, Closure: The bilateral stimulation is applied while the client holds the target memory in mind. Processing is allowed to unfold across multiple sets of eye movements. The therapist guides the client through installation of a positive belief and a body scan to ensure no residual tension. Closure returns the client to stability at the end of each session.
Phase 8 — Re-evaluation: Subsequent sessions begin with reviewing progress and assessing the status of previously processed targets before identifying new ones.
What EMDR Treats
EMDR was originally developed for PTSD and has its strongest evidence base there. It is appropriate for:
- Single-incident PTSD following accidents, assaults, or acute traumatic events
- Combat and military trauma, including PTSD related to operational deployments
- Trauma following narcissistic abuse and coercive relationships
- Childhood abuse and neglect
- Complex PTSD from prolonged or repeated trauma — though this typically requires extended preparation phases and careful pacing
- Phobias and anxiety with identifiable traumatic roots
- Complicated grief following traumatic loss
EMDR vs. Other PTSD Treatments
EMDR is not the only effective PTSD treatment, and it is not right for everyone. Cognitive Processing Therapy (CPT) focuses primarily on changing the distorted beliefs that trauma creates — particularly self-blame and negative worldviews — through structured written exercises and Socratic dialogue. Prolonged Exposure works through systematic, graduated approach to avoided trauma memories and situations. Image Transformation Therapy (ImTT) — Dr. Flores’ specialty — also works with mental imagery but uses a different mechanism, transforming the images themselves rather than processing them through bilateral stimulation. Each approach has its indications, and a skilled clinician selects and sequences them based on the individual’s specific presentation and readiness.
What to Expect in EMDR Sessions
Many people come to EMDR with understandable anxiety about what the experience will be like. Several clarifications are worth making. You do not have to describe the trauma in detail — EMDR can work with the image and the feeling without requiring a verbal account. You will not lose control during processing — the therapist maintains a stabilizing presence throughout. You may experience strong emotions during processing sessions — this is normal and expected, and the therapist is trained to support you through it. Processing typically becomes easier with subsequent sessions as memories lose their emotional charge.
For single-incident trauma, significant improvement is often seen within 8–12 sessions. Complex trauma typically requires a longer course of treatment, with extended preparation and stabilization phases before processing begins.
Beginning EMDR Therapy
Dr. Flores is a certified EMDR therapist with extensive experience applying EMDR to complex trauma presentations, including military trauma, narcissistic abuse, and C-PTSD. She integrates EMDR with other evidence-based approaches — including ImTT and somatic techniques — when indicated by the clinical picture.
