Processing Trauma with EMDR: How Trauma Treatment for PTSD Works

Some negative experiences won’t let us go. They don’t heal on their own. They burn themselves into images that pop up unexpectedly and into a body that remains constantly tense. Positive feelings can hardly find any room in this inner constriction. This is not a weakness, but the reaction of a nervous system that is stuck in a state of alarm.

In my experience, EMDR (Eye Movement Desensitization and Reprocessing) is one of the most effective approaches in trauma therapy. The method uses eye movements to process distressing memories retrospectively. In my practice, I have often seen how this work brings about a fundamental change: What happened remains part of one’s own story, but it loses its power over one’s present experience.

PTSD (post-traumatic stress disorder) is a disorder that can develop after a traumatic event, such as military deployment, a medical procedure, a sexual assault, or a natural disaster. Serious accidents, physical violence, or the sudden loss of a loved one can also be triggers. People with PTSD often experience a range of distressing symptoms, which can be divided into four categories:

Re-experiencing: The traumatic event keeps coming back, in the form of sudden, vivid flashbacks, nightmares, or intense physical reactions whenever something reminds the person of what they went through. It often feels as if the event is happening all over again in that moment.

Avoidance: Those affected try to avoid anything that might remind them of the trauma: certain places, people, activities, or even conversations about what they went through.

Changes in thoughts and mood: Many people affected by this develop negative beliefs about themselves or the world (“It’s my fault,” “You can’t trust anyone”). Emotional numbness and a feeling of inner emptiness are also common.

Hyperarousal: The body is in a constant state of alert. This manifests as jumpiness, sleep disturbances, irritability, or difficulty concentrating. It is as if the nervous system were constantly on guard against new dangers, even when there is objectively no threat.

Depressive symptoms often develop as well, including low mood, lack of motivation, and hopelessness.

Today, there are well-researched and effective treatment methods for PTSD. Among the most important are:

EMDR (Eye Movement Desensitization and Reprocessing): a form of therapy in which distressing memories are processed using eye movements (more on this below).

Trauma-focused behavioral therapy: various approaches in which distressing memories are gently addressed to reduce their emotional impact.

Body-oriented approaches such as Somatic Experiencing: these focus on working with the physical reactions to trauma.

Medications: Certain antidepressants in particular (known as SSRIs), such as sertraline, can alleviate symptoms and support psychotherapy. However, they are not a substitute for psychotherapy, but rather a possible complement to it.

In a supporting role, methods such as yoga, meditation, or breathing exercises can also be helpful. They promote body awareness and help calm the nervous system.

Every person has their own story, and it often takes a little patience to find the right psychotherapist. Good therapeutic support takes your personal history and individual needs into account.

When traumatic experiences are linked to early wounds, internal conflicts, or recurring relationship patterns, depth psychology-based understanding provides another point of access.

As a psychotherapist, it is a fulfilling experience to see people make progress. That is why I am a strong advocate of EMDR. Changes often become apparent surprisingly quickly.

In the case of trauma, the experience is not stored in memory like a normal memory. Instead, images, sounds, physical sensations, and emotions remain unprocessed, like puzzle pieces that were never put together to form a complete picture. Later, when something reminds you of the experience, these fragments are triggered, and it feels as if you’re right back in the middle of it.

EMDR helps the brain process and make sense of these experiences retroactively. The goal is to allow the memory to remain without overwhelming the present. It is part of one’s own history, but no longer dictates how one experiences the here and now.

EMDR is part of treatment, and I do not offer treatment. Anyone looking for treatment can find out how to get it in the article on how to find a psychotherapist. What I offer myself is listed on the page about online psychological counseling.

In EMDR, the distressing memory and the associated feelings, thoughts, and physical sensations are first discussed and gently brought to the surface.

Next comes the central part of the method: As you visualize the distressing scene, you follow the therapist’s finger movements with your eyes. This technique is called dual attention. You are simultaneously engaged with the memory of the past and, through the eye movements, remain anchored in the safe here and now.

Think of it this way: You have one foot in the past and one foot in the safety of the present. This allows you to face the painful memory without being overwhelmed by it.

Important to know: You don’t lose control during this process. On the contrary, you learn to view even distressing memories from a safe vantage point. Focusing on the memory while moving your eyes helps the brain reprocess and contextualize the distressing experience.

Little by little, the memory loses its emotional impact. What you went through becomes a past experience that you can look back on without being overwhelmed by it.

EMDR is not a single technique, but rather an eight-phase process. Francine Shapiro, who developed the approach, defined it this way, and the Federal Joint Committee describes it in its decision documents using the same eight steps.

These eight phases and the three phases of trauma treatment are not contradictory. Stabilization, processing, and integration describe the entire course of treatment. The eight phases describe how a single memory is processed within that course.

• History taking and treatment planning. We clarify what you bring with you and whether EMDR is an option for you. This is where we develop a plan for which memories to address and in what order.
• Preparation and stabilization. You’ll learn how to calm yourself down and get back out of a distressing memory. The amount of time this takes varies: for a single event, it often takes little time, but after years of distress, it takes significantly longer.
• Assessment. We focus on a specific memory: the image, the thought associated with it, the feeling, and the part of the body where it is located. The level of distress and the degree of conviction are recorded on a scale so that change can be measured.
• Desensitization. The core of the process. You briefly engage with the distressing memory while bilateral stimulation is running, usually through eye movements. Sounds or brief physical contact are also possible. The distress decreases round by round.
• Installation. The helpful thought about oneself is reinforced and linked to the memory.
• Body scan. We go over the memory one more time, paying attention to see if there is any residual tension left anywhere in the body.
• Closure. Every session ends with you leaving the room in a stable state, even if a memory has not been fully processed yet.
• Reevaluation. At the start of the next session, we’ll take a look at what remains and what has changed in the meantime.

Phases three through six are repeated for each memory that is processed. The number of sessions required depends on whether the issue involves a single event or something that went on for years. According to the Psychotherapy Guidelines, a therapy session lasts at least 50 minutes, and a double session lasts at least 100 minutes.

Yes, under three conditions, and those conditions are more specific than is usually portrayed.

The Federal Joint Committee decided on EMDR on October 16, 2014, and it became a benefit covered by statutory health insurance on January 3, 2015. The three conditions are listed in the Psychotherapy Guidelines: it is about adults, it is about post-traumatic stress disorder, and EMDR is used within a guideline-based approach, not on its own.

On this third point, many online sources are out of date. They list three possible approaches. Since a decision on March 21, 2024, there are four: behavioral therapy, depth psychology-based psychotherapy, analytical psychotherapy, and systemic therapy. In addition, the treating professional must demonstrate a qualification in the treatment of post-traumatic stress disorder, including EMDR.

This health insurance coverage does not apply to children and adolescents. Notably, in March 2026, the Scientific Advisory Board for Psychotherapy determined that EMDR is scientifically recognized for children and adolescents as well. Thus, professional recognition and health insurance reimbursement have diverged on this point.

These three conditions do not apply outside of statutory health insurance. Anyone who pays for EMDR treatment out of pocket does not need to submit an application or provide a diagnosis that ends up in the health insurance provider’s records, nor are they bound to one of the four guideline-based approaches. The cost of a session at a private practice is listed on the page about the costs of seeing an online psychologist.

For isolated, clearly defined traumatic experiences, EMDR can often be effective relatively quickly. However, in cases of trauma that occurred long ago or involved repeated traumatic events (for example, from childhood), the entire therapeutic process usually takes significantly longer.

A central principle of trauma treatment is this: Before the actual work on the distressing memories begins, sufficient internal and external safety must be established. This means:

External safety: Is there still contact with the person who caused the trauma (contact with the perpetrator)? Is the living situation stable? Are basic living conditions secure? As long as a patient is still under acute threat or living in extremely chaotic circumstances, trauma processing is not advisable.

Inner stability: Do you have enough strategies to calm yourself when distressing emotions arise? Can you tell whether these emotions are related to the present or are old memories? Without these skills, there is a risk that therapy will overwhelm you again instead of providing relief.

The stabilization phase serves exactly this purpose. Here, you’ll learn techniques to calm yourself, build inner security, and better cope with memories that come to mind. How long this takes varies from person to person.

There is one limitation, and it is new. The S3 guideline on post-traumatic stress disorder has explicitly stated since February 2026 that there is no evidence that a stabilization phase is generally necessary before trauma-focused treatment in adults. Stabilization, therefore, is not a mandatory program that pushes all processing back by months. It is what you need to find your way back out of a memory. How much of it is necessary depends on your situation, not on a set formula, and experience shows that more is needed in cases of early, repeated traumatization than in cases involving a single event.

EMDR has not only proven effective in the treatment of PTSD, but has also shown promising results in the treatment of anxiety disorders and depression. In Germany, EMDR is recognized as a psychotherapeutic method for adults with PTSD and recommended by many professional associations.
