What Is EMDR Therapy?

What Is EMDR Therapy?

EMDR — Eye Movement Desensitisation and Reprocessing — is a structured psychotherapy that helps people process and recover from the psychological impact of traumatic or distressing experiences. Developed in the late 1980s by American psychologist Francine Shapiro, EMDR is now one of the most extensively researched trauma therapies in existence.

The therapy works by using bilateral stimulation — most commonly guided side-to-side eye movements — while you briefly bring a distressing memory to mind. This bilateral activation of the brain appears to facilitate the natural information processing system, allowing stuck or fragmented traumatic memories to be integrated in a more adaptive, less distressing way.

Both NICE (the National Institute for Health and Care Excellence) and the World Health Organisation recommend EMDR as a first-line treatment for post-traumatic stress disorder (PTSD). NICE guideline NG116 specifically names EMDR alongside trauma-focused CBT as the recommended treatments for PTSD in adults.

What distinguishes EMDR from many other trauma therapies is that it does not require you to describe your traumatic experience in detail or complete extensive homework between sessions. The processing happens largely through the bilateral stimulation protocol itself, guided by your therapist. Many people find this makes EMDR more accessible than approaches that involve written or prolonged verbal exposure.

EMDR is delivered in individual sessions with a trained therapist. Sessions are typically 50–90 minutes. A standard course of treatment ranges from 6 to 12 sessions, though this varies depending on the complexity and number of traumatic events being addressed.

How Does EMDR Work?

EMDR is based on the Adaptive Information Processing (AIP) model, which proposes that the mind has a natural ability to process experiences and integrate them into existing memory networks. When something traumatic or highly distressing happens, this processing system can become overwhelmed, leaving the memory stored in a raw, unprocessed state — still carrying the original emotions, physical sensations, and beliefs from the moment of the event.

These unprocessed memories can be triggered by current situations, causing intrusive thoughts, flashbacks, heightened anxiety, or other post-traumatic symptoms. The AIP model suggests that these symptoms are not signs of permanent damage but rather evidence of incomplete processing.

Bilateral stimulation is the mechanism EMDR uses to engage the brain's natural processing capacity. During processing, you hold a distressing memory briefly in mind — including its associated image, emotion, and physical sensation — while simultaneously tracking the therapist's fingers as they move from side to side across your visual field. Bilateral stimulation can also be delivered through alternating taps on the hands or knees, or through alternating auditory tones delivered through headphones.

The exact neurological mechanism is still being studied, but leading theories suggest the bilateral stimulation mimics the rapid eye movement (REM) stage of sleep, during which the brain naturally consolidates and processes emotional memories. Studies using functional MRI have shown changes in brain activity following EMDR that are consistent with successful memory consolidation.

As bilateral stimulation proceeds in sets of 20–40 movements, you are asked briefly to notice what comes up — an image, a thought, a feeling, or a body sensation. The therapist then guides the next set of movements. Over successive sets within a session, most people notice the distress associated with the target memory decreasing, and the memory becoming more distant, less emotionally charged, or gaining new perspective.

The World Health Organisation's 2013 guidelines on the management of conditions specific to stress specifically cite EMDR alongside trauma-focused CBT as the recommended treatments for PTSD in adults and children, noting its particular value where verbal disclosure is difficult.

What Can EMDR Help With?

EMDR is most strongly evidenced for post-traumatic stress disorder and trauma, where NICE guideline NG116 places it alongside trauma-focused CBT as the recommended treatment. However, the clinical evidence base extends considerably beyond PTSD.

• Post-traumatic stress disorder (PTSD) — the primary evidence base, recommended by NICE NG116 and WHO
• Complex trauma and childhood abuse or neglect
• Anxiety disorders, including generalised anxiety and panic disorder
• Specific phobias rooted in past experiences
• Depression with identifiable precipitating events
• Grief and complicated bereavement
• Performance anxiety in professional or sports contexts
• Trauma related to medical procedures or chronic illness
• Low self-esteem or negative core beliefs tied to past experiences

The Eight Phases of EMDR

EMDR follows a structured eight-phase protocol developed by Francine Shapiro. Each phase has a specific purpose, and the phases are worked through in sequence across the course of treatment.

**Phase 1 — History Taking and Treatment Planning:** Your therapist gathers a thorough personal history, identifies the traumatic or distressing experiences to be targeted, and maps out the treatment sequence. This phase also involves assessing your readiness and identifying any stabilisation needs before processing begins.

**Phase 2 — Preparation:** Your therapist explains the EMDR model and the bilateral stimulation process, answers your questions, and teaches resourcing and grounding techniques. These are skills you can use during and between sessions to manage distress. The therapeutic relationship is established and trust is developed before any processing begins.

**Phase 3 — Assessment:** Before processing a specific memory, your therapist helps you identify the target memory clearly — including the most distressing image, the negative belief you hold about yourself in relation to it (such as "I am powerless"), the positive belief you would prefer to hold, the associated emotions, and where you feel the distress in your body. Baseline distress is measured using the Subjective Units of Disturbance (SUD) scale (0–10) and the Validity of Cognition (VOC) scale.

**Phase 4 — Desensitisation:** The core processing phase. You hold the target memory in mind while following bilateral stimulation in sets. Between sets, your therapist checks in briefly on what is arising. Sets continue until the SUD score reaches 0 or 1 — indicating that the memory no longer triggers significant distress.

**Phase 5 — Installation:** Once distress is reduced, you focus on strengthening the positive belief identified in Phase 3, pairing it with the target memory using bilateral stimulation until the VOC score reaches 6 or 7 out of 7.

**Phase 6 — Body Scan:** You bring the target memory and positive belief to mind simultaneously and scan your body from head to toe, noticing any residual physical tension or discomfort. Any remaining bodily distress is addressed with further bilateral stimulation.

**Phase 7 — Closure:** Every session ends with a closure procedure designed to leave you in a state of equilibrium. If processing is not complete, your therapist uses containment techniques to help you safely store the material until the next session. You may be asked to keep a brief journal to note anything that arises between sessions.

**Phase 8 — Re-evaluation:** At the start of subsequent sessions, your therapist checks how you have been since the previous session, reviews progress on previously processed memories, and identifies new targets if needed.

What to Expect in an EMDR Session

An EMDR session typically lasts 50 minutes, though extended 90-minute sessions are sometimes used for intensive processing work. Early sessions — usually the first two or three — are not processing sessions. They are dedicated to history taking, building the therapeutic relationship, and preparation, including practising resourcing techniques.

When active processing begins, you will be seated comfortably facing your therapist. You will not be required to recount your traumatic experience in detail. Your therapist will guide you to hold a brief image or thought related to the target memory in mind, and then follow the bilateral stimulation — typically a hand moving side to side across your field of vision at a pace that feels comfortable.

Bilateral stimulation is delivered in sets, each lasting 20–40 movements. After each set, your therapist will ask you simply to notice what comes up: "What are you noticing now?" or "What came up for you?" You respond with whatever arises — an image, a body sensation, an emotion, a thought — and your therapist uses this to guide the next set.

Many people experience shifts in the emotional intensity of the memory within a single session. Some experience transient emotional discomfort during processing, which is normal and expected. Your therapist will pace the work carefully and check your window of tolerance throughout.

A typical course of treatment is 6–12 sessions. Single-incident traumas (such as a road accident or a single assault) often resolve in fewer sessions than complex or repeated trauma. Raymond works with both types and will discuss a realistic treatment timeline with you in an initial consultation.

Is EMDR Right for Me?

EMDR is most likely to help people who have identifiable traumatic or distressing experiences that continue to affect their daily life — through intrusive memories, heightened anxiety, avoidance, low self-worth, or emotional reactivity that feels disproportionate to current situations.

You do not need to have a formal PTSD diagnosis to benefit from EMDR. Many people seeking therapy for anxiety, depression, or relationship difficulties find that these difficulties have roots in past experiences that respond well to EMDR processing.

There are some circumstances where a period of stabilisation work is appropriate before EMDR processing begins. Active, untreated substance misuse, certain dissociative disorders, and severe emotional dysregulation may indicate that resourcing and stabilisation work should be prioritised first. A thorough initial assessment will identify whether you are ready to begin processing or whether some preparatory work would be beneficial.

If you are curious whether EMDR could help with your particular history and presentation, an initial consultation provides the opportunity to discuss this directly. There is no obligation to commit to a full course of treatment until you are confident it is the right approach for you.

EMDR vs CBT for Trauma

Both EMDR and Trauma-Focused Cognitive Behavioural Therapy (TF-CBT) are recommended by NICE guideline NG116 as first-line treatments for PTSD. Understanding how they differ can help you consider which approach may suit you better.

Trauma-Focused CBT works by helping you examine and challenge unhelpful thoughts and beliefs related to the traumatic event, and by working through a structured narrative of the trauma. It typically involves written accounts and imaginal exposure to the traumatic memory, which can be highly effective but requires significant engagement with the trauma narrative over multiple sessions.

EMDR does not require a detailed verbal account of the traumatic experience. Processing occurs largely through the bilateral stimulation protocol, with the client holding brief mental images rather than constructing extended narratives. Many people who have found trauma narratives difficult to manage find EMDR more accessible as a result.

EMDR tends to work directly with specific memories, making it particularly well-suited for trauma that can be identified and targeted discretely. TF-CBT, with its cognitive restructuring component, may be particularly valuable where trauma has resulted in deeply held, distorted beliefs about the world that need systematic examination.

The decision between EMDR and CBT is not a matter of one being superior — both have strong evidence bases. It is more a question of fit: your personal preferences, the nature of your trauma, and what feels right in an initial consultation. A trained therapist will help you weigh the options based on your individual history and goals.

Summary

EMDR is a well-evidenced, NICE and WHO-recommended therapy for trauma and PTSD that works by using bilateral stimulation to help the brain reprocess distressing memories. It does not require detailed verbal recounting of trauma, making it accessible to many people who have found other approaches difficult.

A standard course of EMDR is 6–12 sessions. It is effective for PTSD, complex trauma, anxiety, phobias, and a range of other difficulties rooted in past experience.
