EMDR, or Eye Movement Desensitization and Reprocessing, is a structured trauma-focused psychotherapy that helps people process distressing memories so they feel less overwhelming over time. It is one of the most studied treatments for posttraumatic stress disorder and is suggested by major professional guidelines as an option for many adults with PTSD when delivered by trained clinicians.

What EMDR is
EMDR was developed in the late 1980s by psychologist Francine Shapiro to help people resolve persistent traumatic memories. It is based on the Adaptive Information Processing model, which proposes that some experiences are stored in ways that remain unprocessed and continue to trigger distressing images, sensations, and beliefs long after the events are over.
Clinical practice guidelines from organizations such as the American Psychological Association, the US Department of Veterans Affairs and Defense, and the National Institute for Health and Care Excellence include EMDR among trauma-focused psychotherapies for PTSD. EMDR is usually offered one or two times per week. Processing a specific memory is often completed within one to three sessions, although overall treatment length depends on the person and the complexity of their history.
How EMDR works in principle
EMDR focuses directly on the trauma memory rather than spending extensive time on detailed storytelling or cognitive restructuring. During an EMDR session, the therapist invites the person to briefly bring a specific memory into awareness, including the associated image, negative belief, emotions, and body sensations.
While the memory is active, the therapist guides bilateral stimulation, such as rhythmic left-right eye movements, alternating tones in headphones, or gentle taps on the hands. Clinical observations and research suggest that this combination of focused attention and bilateral stimulation supports the brain’s natural ability to reprocess traumatic material. Over time, the vividness and emotional charge of the memory often reduce and more adaptive beliefs become easier to access.
Unlike some trauma-focused therapies, EMDR does not require extended verbal exposure to the event, detailed recounting of the trauma, or homework between sessions. Many people find this structure more tolerable, particularly when talking about the event in detail feels difficult or unsafe.
The eight phases of EMDR therapy
EMDR uses a standardized eight-phase structure.
History and treatment planning. The therapist gathers information, identifies possible trauma targets, and collaborates on a treatment plan.
Preparation. The therapist explains EMDR, builds relational safety, and teaches basic regulation skills so the person can tolerate activation during processing.
Assessment of the target memory. A specific event is chosen and linked to an image, a negative cognition such as I am unsafe or I am powerless, emotions, body sensations, and a desired positive cognition.
Desensitization. The person focuses on the memory while receiving bilateral stimulation. They notice any images, thoughts, or sensations that arise and allow them to shift without forcing a particular outcome.
Installation of positive cognition. As distress decreases, bilateral stimulation continues while the person focuses on a more adaptive belief about the event.
Body scan. The person checks for any remaining tension or discomfort in the body. If sensations are still present, additional sets of bilateral stimulation may be used.
Closure. Each session ends with grounding and containment so the person leaves in as regulated a state as possible, even if processing is still underway.
Re evaluation. At later sessions, the therapist and person review what has changed and decide whether to return to the same memory or move on to new targets.
Research on EMDR
Systematic reviews and meta-analyses indicate that EMDR is effective for many people with PTSD.
One meta-analysis of randomized controlled trials found that EMDR significantly reduced symptoms of PTSD, depression, anxiety, and subjective distress compared with control conditions. Clinical practice guidelines and evidence briefs from agencies such as the VA and Department of Defense report that EMDR is more effective than waitlist or usual care and can be considered a first-line or strongly recommended treatment for PTSD in several systems.
Recent work suggests that EMDR can reduce depressive symptoms to a similar extent as some forms of trauma-focused cognitive behavioral therapy in certain contexts. At the same time, guidelines now often classify EMDR as a conditional or second-line recommendation compared with approaches such as Cognitive Processing Therapy and Prolonged Exposure, which have a broader evidence base.
Overall, the evidence suggests that EMDR can be an important option for trauma treatment, especially when it is integrated into a phase-oriented and trauma-informed plan.
What an EMDR session may feel like
Experiences of EMDR are individual, but a typical session has a recognizable rhythm.
The therapist begins with a brief check-in to see how the person is arriving and may use simple grounding or body-awareness practices to support regulation. Together they identify a memory or theme to work with and clarify the associated beliefs and sensations.
The therapist then guides sets of bilateral stimulation while the person pays attention to whatever arises. Between sets, they pause and the person reports what they notice, such as new images, changes in feeling, or shifts in the body. The therapist helps track safety and pacing so the work stays within a tolerable range.
Toward the end of the session, the focus returns to grounding and stabilizing. The person is reminded that additional processing may continue between sessions and that they can use regulation tools if activation arises.
EMDR and somatic therapy
Somatic therapy, which Embodywise focuses on, recognizes that trauma lives in the body as patterns of activation, collapse, and muscle tension as well as in thought. Somatic approaches pay attention to breath, posture, felt sense, and nervous system states so that healing is not only cognitive.
Integrative clinicians often combine EMDR with somatic tools to help people stay grounded during processing. Before EMDR work, somatic practices such as orienting to the environment, feeling the contact of the feet with the floor, or tracking breath can support a stronger sense of present-time safety.
During EMDR, noticing sensations such as tightness, numbness, or urges to move can help guide pacing and keep the work within a window of tolerance. After EMDR sessions, gentle movement, mindful body awareness, or other somatic exercises may help the nervous system settle and integrate changes.

Hakomi-informed perspectives on EMDR
Hakomi Mindful Somatic Psychotherapy shares with EMDR a focus on present-moment experience and the belief that healing requires attention to both mind and body. Hakomi emphasizes mindfulness, nonviolence toward defenses, and careful pacing based on nervous system capacity.
From a Hakomi-informed perspective, EMDR can be one way to access and process traumatic material, while Hakomi principles and methods provide a relational and somatic frame that supports safety. Therapists grounded in Hakomi often attend closely to consent, the pace of work, and the client’s internal signals, and they may weave EMDR into a broader process that includes attachment work, parts work, and somatic tracking.
If you are a practitioner who wants to deepen your capacity to integrate EMDR with mindful somatic work, Embodywise’s Hakomi Overview, Trainings and Workshops page offers more detail on training in Hakomi and somatic psychotherapy.
Who EMDR may help and important considerations
EMDR is most commonly used for people with PTSD related to events such as accidents, assaults, disasters, combat, or medical trauma. It is also applied in some cases of anxiety, complicated grief, and distress that is clearly linked to adverse experiences.
There are important considerations.
EMDR should be delivered by properly trained and licensed clinicians who have experience working with trauma and dissociation. For people with complex trauma histories, significant dissociation, or limited current safety, many guidelines and trauma-informed frameworks recommend a phase-oriented approach that begins with stabilization and resource building before intensive trauma processing.
People with medical conditions or particular psychiatric presentations may need adapted pacing or may benefit from starting with other approaches. These decisions are best made in conversation with a qualified provider who can consider the whole person and their context.
If you are exploring EMDR, you might ask a therapist how they work with preparation, pacing, and somatic regulation.
