EMDR Explained: More Than Moving Your Eyes

Eye Movement Desensitization and Reprocessing Therapy (EMDR) is a mouthful—and I’ll admit, it can sound a little strange. Before I was trained in EMDR, I had the same question many clients have: “Someone watches a light move back and forth and suddenly feels better?”

I was skeptical. Then I worked alongside clinicians who valued research and were seeing meaningful changes with clients using EMDR. Eventually, I decided to complete the training and understand the process for myself. I’m glad I did.

What Is EMDR Therapy?

EMDR is a structured form of psychotherapy originally developed to treat post-traumatic stress disorder (PTSD). It helps people process distressing memories and the thoughts, emotions, and physical reactions connected to them.

Traumatic experiences can leave people with beliefs such as:

• “The world isn’t safe.”
• “I have no control.”
• “I’m not good enough.”
• “It was my fault.”

EMDR helps the brain process the experience so the memory can feel less immediate and overwhelming. The event remains part of your history, while its emotional intensity and influence may decrease.

How Does EMDR Work?

Here is what EMDR may look like during a session. Your therapist asks you to briefly focus on a distressing memory while noticing the thoughts, emotions, or physical sensations that come with it. At the same time, you engage in bilateral stimulation—alternating visual, auditory, or tactile input from one side to the other.

Bilateral stimulation may involve:

• Following the therapist’s fingers or a moving light with your eyes
• Listening to tones that alternate between your ears
• Holding small devices that pulse from one hand to the other
• Alternating taps on your hands, knees, or shoulders

This may sound complicated, but the basic idea is fairly simple. You keep one foot in the memory and one foot in the present. Your therapist pauses between short sets of bilateral stimulation, asks what you notice, and helps guide where the process goes next.

Over time, this process can reduce the fight-or-flight response connected to the memory. The brain begins to recognize that remembering the experience is different from being back in danger. In plain language, you are learning, “I can think about this and still be safe in the present.”

Researchers are still studying exactly why EMDR works. Current explanations involve working memory, attention, and the brain’s ability to integrate distressing experiences. Watching a light move back and forth is only one part of a structured therapy process.

What Happens in EMDR Therapy?

Many people picture EMDR beginning immediately with eye movements and a painful memory. In reality, EMDR follows a structured eight-phase process. You may spend more than one session in a phase, and your therapist may return to an earlier phase as your needs change.

The Eight Phases of EMDR

1. History and treatment planning: You and your therapist discuss your concerns, history, current symptoms, and goals. Together, you identify experiences or patterns that may become treatment targets.
2. Preparation: Your therapist explains the process, answers questions, and helps you develop skills for managing distress. Readiness and trust matter before trauma processing begins.
3. Assessment: You identify the memory, image, negative belief, emotions, and physical sensations connected to the experience. You also choose a more helpful belief you would like to strengthen.
4. Desensitization: You briefly focus on the memory while engaging in sets of bilateral stimulation. Your therapist checks in between sets and follows the thoughts, feelings, images, or sensations that arise.
5. Installation: You focus on strengthening the more helpful belief connected to the experience.
6. Body scan: You notice whether any tension, discomfort, or other physical response remains when you think about the memory.
7. Closure: Your therapist helps you feel grounded before the session ends, whether the memory has been fully processed or the work will continue later.
8. Reevaluation: At the beginning of a later session, you and your therapist review what has changed and decide what needs attention next.

EMDR moves at a pace determined by your readiness, responses, and treatment goals. A trained therapist should explain what is happening and invite your feedback throughout the process.

What Can EMDR Help With?

EMDR has the strongest research support as a treatment for post-traumatic stress disorder (PTSD) and trauma-related symptoms. It can be adapted for children, teens, and adults.

A therapist may consider EMDR when past experiences are connected to:

• Distressing or intrusive memories
• Flashbacks, nightmares, or strong emotional triggers
• Avoidance of reminders connected to an experience
• Persistent shame, guilt, fear, or negative beliefs
• Difficulty feeling safe after something threatening or overwhelming
• Panic attacks connected to distressing experiences, feared sensations, or specific triggers
• Phobias or fears connected to a distressing experience

At Elevate, EMDR may be integrated into a broader treatment plan based on the person’s symptoms, history, and goals.

Is EMDR Evidence-Based?

Yes. EMDR is supported by extensive research and is included in major clinical guidelines for treating PTSD, including those from the American Psychological Association and the U.S. Department of Veterans Affairs and Department of Defense.

Research shows that EMDR can reduce PTSD symptoms and help people process the memories, beliefs, emotions, and physical reactions connected to trauma. Its strongest research support is for PTSD and trauma-related symptoms.

That research matters, but choosing a therapy is also personal. EMDR can feel unusual at first, and no approach is the right fit for everyone. A therapist trained in EMDR can explain what to expect, answer your questions, and help determine whether it makes sense for your experiences and treatment goals.

Why I Use EMDR in My Practice

One reason I value EMDR is that clients often understand something logically while continuing to feel it emotionally and physically. You may know that the experience is over, that you are safe now, or that what happened was not your fault—and still notice your body reacting as though the danger is present.

Talking can provide insight into these patterns, but insight alone does not always change the nervous system’s response. EMDR gives us another way to work with the memories, beliefs, emotions, and physical reactions that continue to feel unresolved.

I also appreciate that clients do not always have to describe every detail of an experience aloud. They remain aware and in control throughout the process, and we move at a pace that feels manageable. For many people, EMDR helps bridge the gap between knowing, “I am safe now,” and beginning to feel that safety more fully.

Is EMDR Right for You?

EMDR may be worth considering if a distressing experience continues to affect how you feel, think, react, or relate to others. You do not need to have a PTSD diagnosis—or be certain that an experience “counts” as trauma—to ask whether EMDR could help.

A therapist trained in EMDR can help you explore whether the approach fits your needs, whether additional preparation may be helpful, or whether another form of therapy would be a better match. Asking questions and understanding the process can help EMDR feel much less mysterious—and certainly more meaningful than simply moving your eyes back and forth.
