Understanding EMDR: A Comprehensive Guide to Eye Movement Desensitization and Reprocessing

What Is EMDR Therapy?

Eye Movement Desensitization and Reprocessing (EMDR) is a powerful, evidence-based therapy for healing trauma and emotional distress. Originally developed by Francine Shapiro in the late 1980s, EMDR is now widely used around the world to treat post-traumatic stress disorder (PTSD), complex trauma, anxiety, phobias, and more.

Unlike traditional talk therapy, EMDR does not require people to describe their traumatic experiences in detail. Instead, it uses bilateral stimulation—typically eye movements—to help the brain reprocess memories and reduce emotional distress.

How EMDR Works
EMDR is based on the idea that psychological distress is often rooted in unprocessed memories. When a traumatic or overwhelming event occurs, the brain’s natural ability to process information can become disrupted. As a result, memories of the event may remain “stuck,” triggering emotional, physical, or behavioral responses long after the danger has passed.

EMDR helps re-activate the brain’s natural processing system. During an EMDR session, the therapist guides the client through a series of standardized steps, often while the client follows a set of back-and-forth eye movements or other forms of bilateral stimulation (such as tapping or audio tones).

This process allows the brain to integrate the memory in a healthier way—reducing the emotional charge, shifting negative beliefs, and allowing the person to move forward.

The 8 Phases of EMDR Therapy
EMDR follows a structured 8-phase protocol designed to ensure safety, stabilization, and thorough processing.

1. History-Taking & Treatment Planning
   The therapist gathers a full clinical picture and identifies targets for EMDR—specific memories, present triggers, and future fears.

2. Preparation
   The therapist explains the EMDR process, sets expectations, and teaches self-soothing techniques to help the client feel grounded and in control.

3. Assessment
   The client identifies a target memory along with the associated image, negative belief, emotions, and body sensations. The therapist uses two subjective scales (SUD and VOC) to measure distress and belief strength.

4. Desensitization
   Using bilateral stimulation, the client focuses on the target memory while the brain begins to process. Distress usually decreases over several sets.

5. Installation
   The therapist helps strengthen a positive belief (e.g., “I am safe now” or “I did the best I could”), replacing the old, negative belief.

6. Body Scan
   The client observes the body for residual tension or discomfort related to the memory. If any remains, it is processed further.

7. Closure
   The therapist ensures the client feels stable at the end of the session, regardless of whether the memory was fully processed that day.

8. Reevaluation
   At the next session, the therapist checks the previous work and identifies the next target memory or issue to process.

What EMDR Can Treat
While EMDR was initially developed for PTSD, research and clinical experience have shown it to be effective for a wide range of issues, including:

• Childhood trauma

• Complex PTSD

• Anxiety and panic disorders

• Depression

• Phobias

• Grief and loss

• Dissociation

• Attachment wounds

• Performance anxiety

• Medical trauma

• Sexual abuse

• Emotional neglect

How EMDR Feels for Clients
Clients often describe EMDR as intense but empowering. The process can bring up strong emotions, but it typically results in a sense of relief, insight, and resolution. Many people report that distressing memories feel more distant or “like they happened to someone else.”

Importantly, EMDR does not erase memories—it helps the brain file them away appropriately, so they no longer intrude on the present.

EMDR and the Brain
Though the exact mechanism is still being researched, studies suggest that EMDR may engage brain regions involved in memory, emotion, and body regulation—including the amygdala, hippocampus, and prefrontal cortex.

Some theories propose that bilateral stimulation mimics aspects of REM (rapid eye movement) sleep, a time when the brain naturally processes emotional material.

Is EMDR Right for Everyone?
EMDR can be transformative, but it’s not a fit for every client or every stage of treatment. Some clients need significant stabilization or support with emotional regulation before they are ready to process trauma directly. Others may benefit from combining EMDR with parts work, somatic therapy, or cognitive approaches.

A skilled trauma therapist will work collaboratively to determine whether EMDR is appropriate, and when to use it.

In-Person and Virtual EMDR
EMDR can be delivered both in person and virtually. In remote sessions, therapists often use online tools or visual cues for bilateral stimulation. Many clients find virtual EMDR just as effective as in-person treatment.

Finding an EMDR Therapist
If you're considering EMDR, look for a therapist trained by an EMDRIA-approved provider. Certification isn’t required to practice EMDR, but it reflects additional training and experience.

Trauma-informed care is essential. A good EMDR therapist will go at your pace, ensure safety, and integrate EMDR into a broader healing plan.
