EMDR Phases: A Complete Guide to How EMDR Therapy Works
If you have heard about EMDR therapy but are not sure what happens during treatment, you are not alone. Understanding the EMDR phases can make the process feel less unfamiliar and help you know what to expect before beginning therapy.
EMDR, or Eye Movement Desensitization and Reprocessing, is a structured form of psychotherapy that is commonly used to help people process distressing memories and experiences. Unlike approaches that rely primarily on talking through difficult events, EMDR uses a structured treatment process that includes preparation, memory assessment, reprocessing, and evaluation.
At Radiant Path Therapy in Grand Terrace, CA, our trauma-specialized therapists provide individualized support throughout the EMDR process. Treatment is adapted to each person's needs, history, and level of readiness rather than following a one-size-fits-all schedule.
In this guide, you'll learn what EMDR therapy is, how it works, what happens during each phase, how long treatment may take, and what you can expect during an EMDR session.
What Is EMDR Therapy?
EMDR stands for Eye Movement Desensitization and Reprocessing. It is a form of psychotherapy developed to help people process distressing experiences, particularly traumatic memories.
EMDR was originally developed as a treatment for post-traumatic stress disorder (PTSD). It is now used by clinicians with people experiencing a range of trauma-related and other psychological difficulties, depending on the individual's circumstances and treatment needs.
One feature of EMDR is bilateral stimulation. This may involve guided eye movements, alternating taps, sounds, or another form of left-right stimulation. The specific method can vary between therapists and clients.
Rather than requiring a person to describe every detail of a distressing experience repeatedly, EMDR uses a structured process in which the therapist helps the client focus on selected aspects of a memory while guiding the reprocessing work.
How Does EMDR Therapy Work?
EMDR is based in part on the Adaptive Information Processing (AIP) model. Understanding this model can help explain why distressing memories may continue to affect someone long after an event has ended.
The Adaptive Information Processing Model
The AIP model proposes that the brain has an adaptive system for processing and storing experiences. Normally, new experiences become integrated with existing knowledge and memories.
When an experience is particularly overwhelming or distressing, however, aspects of the experience may remain insufficiently processed. The memory can continue to be associated with strong emotions, thoughts, beliefs, or physical sensations.
Why Traumatic Memories Can Remain Distressing
A distressing memory may continue to trigger an emotional or physical response even when the person is no longer in danger.
For example, a reminder of a past event may bring back fear, helplessness, shame, or other reactions associated with the original experience. These responses can sometimes affect how a person sees themselves, other people, or the world around them.
How EMDR Supports Memory Reprocessing
During EMDR, a therapist helps the client focus on a selected memory while using structured bilateral stimulation and other therapeutic techniques.
The goal is not to erase the memory. Instead, treatment aims to help the person process the experience so that the memory becomes less distressing and can be understood as something that happened in the past.
People can respond differently to EMDR. Some notice changes in emotional intensity, beliefs, or physical sensations as treatment progresses, while others experience changes more gradually.
What Are the Phases of EMDR Therapy?
EMDR therapy follows an established eight-phase framework. The phases provide a structure for assessment, preparation, reprocessing, and follow-up.
The amount of time spent in each phase can vary considerably. Some people may need more time for preparation and stabilization, while others may progress more quickly through certain parts of treatment.
Phase 1: History Taking and Treatment Planning
The first phase focuses on understanding the client's history, current concerns, and treatment goals.
The therapist may ask about past experiences, current symptoms, relationships, coping strategies, and other factors that may be relevant to treatment.
Together, the therapist and client identify potential memories or experiences that may be appropriate targets for EMDR. The therapist also considers the person's current stability and readiness before developing a treatment plan. This phase provides the foundation for the work that follows.
Phase 2: Preparation
Preparation focuses on helping the client understand the EMDR process and feel sufficiently prepared for reprocessing.
The therapist explains what to expect and works with the client to develop strategies for managing difficult emotions or physical sensations.
Depending on the person's needs, preparation may include grounding exercises, breathing techniques, relaxation strategies, or other stabilization skills.
Some clients may be ready to move into reprocessing relatively quickly, while others may benefit from additional preparation sessions. Taking adequate time during this phase can help establish a sense of safety and control.
Phase 3: Assessment
During assessment, the therapist and client identify a specific target memory or experience for reprocessing.
The client may identify:
The image or part of the memory that feels most disturbing
A negative belief about themselves associated with the memory
A preferred positive belief
Emotions connected with the memory
Physical sensations associated with the memory
The current level of distress
For example, someone might identify a negative belief such as "I am powerless" and a preferred belief such as "I can protect myself now." The therapist uses this information to establish a starting point for the reprocessing work.
Phase 4: Desensitization
Desensitization is the phase in which active memory reprocessing takes place. The therapist asks the client to focus on selected aspects of the target memory while engaging in sets of bilateral stimulation. This may involve eye movements, alternating sounds, or tactile stimulation.
During the process, different thoughts, images, emotions, or physical sensations may arise. The therapist provides guidance while allowing the client's processing to unfold without forcing a particular response. The goal is to reduce the level of disturbance associated with the target memory.
Phase 5: Installation
Once the distress associated with the target memory has decreased sufficiently, treatment moves toward strengthening a more adaptive positive belief. The client identifies the positive belief they would prefer to associate with the experience. The therapist then guides the client through the process of reinforcing that belief.
For example, a person who previously felt "I am powerless" may work toward a belief such as "I have choices now." The therapist may ask the client to rate how strongly the positive belief feels and continue working with it as appropriate.
Phase 6: Body Scan
The body scan focuses on physical sensations that may remain after the emotional intensity of the memory has decreased. The client is asked to notice how their body feels while thinking about the memory and the preferred positive belief.
They may notice tension, discomfort, pressure, changes in breathing, or other sensations. If distressing sensations remain, the therapist can determine whether additional processing is appropriate. This phase helps the therapist assess whether there is remaining physical disturbance associated with the target.
Phase 7: Closure
Closure takes place at the end of an EMDR session, whether or not the target memory has been completely processed. The therapist helps the client return to a stable state before ending the session. Grounding, breathing, relaxation, or other stabilization techniques may be used when appropriate.
The therapist may also explain what the client might notice between sessions. Some people experience new thoughts, emotions, memories, or dreams after reprocessing, which can be discussed during the next appointment. The purpose of closure is to help the client leave the session feeling sufficiently grounded rather than ending immediately after intensive processing.
Phase 8: Reevaluation
Reevaluation typically takes place at the beginning of a subsequent session. The therapist reviews what has happened since the previous session and assesses the client's response to the earlier processing. They may revisit the target memory, the level of distress, the positive belief, and any remaining physical sensations.
Based on this assessment, the therapist determines whether additional processing is needed or whether treatment should move to another target. Reevaluation allows the treatment plan to remain responsive to the client's progress.
How Long Do the EMDR Phases Take?
There is no universal amount of time required for each phase of EMDR. Treatment length depends on factors such as the person's history, treatment goals, the complexity of the memories being addressed, current stability, and how they respond to therapy.
Preparation may take several sessions for some people, particularly when additional stabilization skills are needed. Other clients may progress through certain parts of treatment more quickly.
Rather than focusing on completing each phase as quickly as possible, a qualified therapist will generally consider whether the client is adequately prepared for the next stage of treatment.
What Happens During an EMDR Session?
An EMDR session can look different depending on which part of the treatment process the client is currently working through. Early sessions may focus primarily on history, treatment planning, education, and preparation. Later sessions may include assessment and active reprocessing.
During reprocessing, the therapist may guide the client through bilateral stimulation using eye movements, alternating sounds, or tactile stimulation such as handheld devices. The therapist usually works in short sets and pauses between them to allow the client to notice what has changed or what has come up.
Emotional responses can vary from person to person. Someone may experience sadness, anxiety, anger, relief, physical sensations, or very little noticeable emotion during a particular session. A trained therapist monitors the client's response and adjusts the pace and approach according to their needs.
What Can EMDR Therapy Help With?
EMDR was originally developed for PTSD and trauma-related difficulties, and it remains an important application of the therapy.
Depending on the individual and the clinician's assessment, EMDR may also be incorporated into treatment for other concerns associated with distressing or overwhelming experiences.
EMDR for PTSD and Trauma
EMDR is widely associated with trauma treatment and is used to help people process distressing memories associated with PTSD. Treatment may target experiences connected with symptoms such as intrusive memories, heightened fear responses, or reminders that continue to cause significant distress.
EMDR for Anxiety
Some therapists use EMDR with clients experiencing anxiety, particularly when distress is connected to specific experiences or memories. The therapist determines whether EMDR is appropriate based on the person's symptoms, history, and overall treatment needs.
EMDR for Childhood Trauma
Past experiences from childhood can continue to influence a person's emotions, beliefs, relationships, and responses to reminders later in life. When appropriate, EMDR may be used to help adults process distressing childhood experiences and develop more adaptive beliefs about themselves and their circumstances.
What Are the Potential Benefits of EMDR?
The potential benefits of EMDR vary from person to person. For people who respond well to treatment, processing distressing memories may help reduce their emotional intensity and make reminders easier to manage.
Treatment may also help some people develop more adaptive beliefs about themselves, reduce trauma-related distress, and improve their ability to respond to difficult memories without feeling overwhelmed by them.
However, EMDR is not guaranteed to produce the same results for everyone. A qualified therapist can help determine whether it is an appropriate treatment option for a particular person's needs.
Are There Risks or Side Effects of EMDR?
EMDR is generally considered a structured and professionally delivered form of psychotherapy, but emotional discomfort can occur during or after treatment. Processing distressing experiences may temporarily bring up difficult emotions, memories, physical sensations, or thoughts. Some people may also feel tired or emotionally sensitive after a session.
This does not necessarily mean that treatment is going poorly, but it is important to communicate openly with your therapist about how you are feeling. A trained therapist can adjust the pace of treatment, return to stabilization strategies, or determine whether additional preparation is needed.
If symptoms become significantly worse or you are concerned about your response to treatment, speak with your mental health professional promptly.
Can You Do EMDR on Your Own?
Clinical EMDR therapy is designed to be conducted with a trained mental health professional. Although you may find videos, apps, or exercises online that describe EMDR-style eye movements or bilateral stimulation, these are not equivalent to comprehensive EMDR therapy.
The eye movements or bilateral stimulation are only one component of the broader treatment process. Clinical EMDR also involves assessment, preparation, treatment planning, reprocessing, closure, and reevaluation.
Attempting to deliberately process traumatic memories without appropriate preparation or professional support may cause significant distress for some people. If you are interested in EMDR, a qualified therapist can help determine whether it is appropriate for you and provide stabilization techniques that can be used safely between sessions.
What Happens After EMDR Treatment?
EMDR treatment does not necessarily end after processing a single memory. Depending on the person's treatment goals and history, therapy may involve working with multiple memories or experiences. The treatment framework can be revisited as different targets are addressed.
The therapist continues to evaluate progress and determine whether additional treatment is appropriate. Even after intensive trauma processing, clients may continue using grounding, emotional regulation, and other coping strategies learned during therapy.
Conclusion
EMDR therapy follows a structured process designed to help clients safely work with distressing memories and experiences. The phases move from history and preparation through assessment, reprocessing, closure, and reevaluation.
Although the overall framework is structured, treatment is not identical for everyone. The pace, techniques, and amount of time spent in different phases can be adapted according to a person's needs and treatment goals.
If you are considering EMDR, speaking with a qualified mental health professional can help you understand whether this approach is appropriate for your situation and what you might expect from treatment.

Frequently Asked Questions
What are the phases of EMDR therapy?
EMDR therapy follows eight phases: history taking and treatment planning, preparation, assessment, desensitization, installation, body scan, closure, and reevaluation. Each phase serves a different purpose, from establishing treatment goals and preparing for reprocessing to evaluating progress.
Which phase of EMDR involves eye movements?
Eye movements or other forms of bilateral stimulation are commonly used during the desensitization phase. Bilateral stimulation may also be used during other parts of the reprocessing process, depending on the therapist's approach and the client's treatment needs.
How long does EMDR take to work?
The time required varies from person to person. Some people notice changes relatively early in treatment, while others need more time because of complex trauma histories, multiple treatment targets, or the need for additional preparation.
How many EMDR sessions are needed?
There is no fixed number of EMDR sessions that applies to everyone. Treatment length depends on the individual's goals, history, symptoms, response to therapy, and the complexity of the experiences being addressed.
Is EMDR painful or uncomfortable?
EMDR is not physically painful, but it can sometimes be emotionally uncomfortable. Processing distressing memories may bring up strong emotions, thoughts, or physical sensations. Your therapist can help you manage these responses and adjust the pace of treatment when necessary.
Can EMDR make trauma worse?
Some people experience temporary emotional distress while processing difficult memories. This is different from saying that the underlying trauma is becoming worse. If distress becomes intense, persistent, or difficult to manage, discuss it with your therapist so they can reassess the treatment approach.
Can you do EMDR by yourself?
Clinical EMDR should be conducted by a trained mental health professional. Online exercises involving eye movements or bilateral stimulation are not a substitute for the assessment, preparation, treatment planning, and professional guidance involved in EMDR therapy.
