Somatic EMDR vs. Traditional EMDR: How the Body Shows Up in Every Phase
EMDR is often described in terms of its 8-phase structure — a clear, replicable protocol that's part of why it's one of the most studied trauma treatments available. But that structure can make it easy to overlook something important: the body is present in every single phase, not just the "body scan" step near the end.
Somatic EMDR doesn't throw out the 8-phase model. It deepens it — asking the clinician (and client) to stay in ongoing contact with physical sensation from the very first conversation through final closure. This article walks through each phase of EMDR and shows where body awareness naturally belongs, and introduces one evidence-informed model, S.A.F.E. EMDR, that formalizes this integration.
A Quick Grounding: What Is EMDR?
EMDR (Eye Movement Desensitization and Reprocessing) was developed by psychologist Francine Shapiro in the late 1980s. It's built on the Adaptive Information Processing (AIP) model, which holds that the brain has a natural system for processing experience — but traumatic events can disrupt that system, leaving memories "stuck" along with their original emotional and physical charge. EMDR uses bilateral stimulation (eye movements, taps, or tones) alongside brief recall of a target memory to help the brain complete that stalled processing.
EMDR is delivered through eight distinct phases. Below, we'll walk through each one — and highlight why body sensation deserves attention throughout, not just at the traditional "body scan" checkpoint.
The 8 Phases of EMDR — and Where the Body Belongs in Each
Phase 1: History Taking
Traditional focus: The clinician gathers history, identifies target memories, current triggers, and treatment goals.
Where the body comes in: Even in this first conversation, the body is offering information. A somatically-attuned clinician notices things like shifts in breathing, posture changes, or subtle tension when certain topics come up — often before a client has language for what they're feeling. This early observation helps map where in the body a client tends to hold distress, which shapes the whole treatment plan.
Phase 2: Preparation
Traditional focus: Building coping skills, teaching the "safe/calm place" exercise, and explaining what to expect from processing.
Where the body comes in: This is where somatic-informed EMDR spends significantly more time than the standard protocol. Rather than a brief calming visualization, clients are taught to actually locate and describe physical sensations of calm or resource — noticing where safety "lives" in the body so they have something concrete to return to during processing. Skills like orienting to the room, grounding through the feet, or noticing breath are introduced here to widen what's sometimes called the client's window of tolerance before any distressing material is touched.
Phase 3: Assessment
Traditional focus: Identifying the target image, negative belief, desired positive belief, emotions, and a baseline distress rating (SUDs) tied to the memory.
Where the body comes in: Assessment traditionally includes identifying where in the body the disturbance is felt — but somatic-informed practice treats this as more than a formality. Clients are asked to get specific: is it tight, hot, heavy, buzzing? That felt sense becomes an active reference point that's tracked throughout reprocessing, not just noted once at the start.
Phase 4: Desensitization
Traditional focus: Sets of bilateral stimulation while the client briefly holds the memory, image, and associated disturbance in mind.
Where the body comes in: This is the heart of somatic integration. Rather than checking in only cognitively ("what are you noticing now?"), a somatic-informed clinician tracks physical cues throughout — shallow breathing, clenched hands, restlessness, or stillness — and may pace sets of bilateral stimulation more slowly, using the body's signals rather than the clock to guide when to continue or pause. The goal is to let activation in the nervous system move and discharge, rather than pushing through it.
Phase 5: Installation
Traditional focus: Strengthening the connection between the memory and a more adaptive, positive belief.
Where the body comes in: A positive belief that's only cognitive tends to feel less durable. Somatic-informed EMDR asks clients to notice how the new, adaptive belief feels in the body — a sense of expansion, warmth, or ease — helping the shift register as something felt, not just something known intellectually.
Phase 6: Body Scan
Traditional focus: Checking for any remaining physical tension connected to the target memory.
Where the body comes in: This phase already exists in standard EMDR, but it's often treated as a final checkbox — a quick scan to confirm nothing's left before moving on. Somatic-informed practice treats this phase with the same depth as desensitization itself: if tension remains, it's explored and processed rather than simply noted, since unresolved physical residue can signal the memory isn't fully reprocessed yet.
Phase 7: Closure
Traditional focus: Making sure the client leaves each session feeling stable, regardless of whether processing is complete.
Where the body comes in: Closure in somatic-informed EMDR deliberately includes time to return to a felt sense of calm or resource in the body — not just verbal reassurance. This might mean revisiting the grounding or resourcing skills from Phase 2 so the client's nervous system, not just their thinking, feels settled before ending the session.
Phase 8: Re-evaluation
Traditional focus: Reviewing progress at the start of the next session and identifying what still needs attention.
Where the body comes in: Reevaluation asks not just "how do you feel about that memory now?" but "how does your body respond to it now?" Lasting change is often measured by whether the old physical charge — the racing heart, the clenched jaw — has actually settled, not only whether the story feels different.
S.A.F.E. EMDR: An Evidence-Informed Somatic Model
One named approach that formalizes body-and-attachment-informed EMDR across all eight phases is Safety and Attachment Focused EMDR (S.A.F.E. EMDR), developed by EMDR trainer Deborah Kennard. It builds on Shapiro's original Adaptive Information Processing model and layers in four guiding principles — nonviolence, mindful awareness, compassionate assumption, and healthy boundaries — along with polyvagal-informed resourcing for safety and connection.
S.A.F.E. EMDR was specifically designed to address a common challenge in trauma treatment: clients with complex or relational trauma who need more scaffolding around safety and attachment before — and during — memory reprocessing. It maintains fidelity to the standard 8-phase EMDR protocol while giving clinicians a more explicit framework for weaving somatic and attachment-focused resourcing throughout, rather than treating the body as a single checkpoint.
It's worth being precise about the evidence here: S.A.F.E. EMDR inherits the strong research base behind core EMDR and the AIP model, since it doesn't deviate from the standard protocol's structure. However, the added attachment- and polyvagal-informed elements are newer and haven't been independently studied through randomized controlled trials to the same degree as EMDR itself. It's best understood as a clinically developed, EMDRIA-taught refinement of an already evidence-based treatment — not yet a separately validated protocol in its own right.
What the Broader Research Says
Traditional EMDR is one of the most extensively studied trauma treatments in existence. Systematic reviews and meta-analyses have found it significantly reduces PTSD symptoms, and it's recommended as a first-line PTSD treatment by major clinical bodies, including the VA/DoD Clinical Practice Guideline, the International Society for Traumatic Stress Studies, the UK's National Institute for Health and Care Excellence, and the Australian National Health and Medical Research Council. The American Psychological Association also includes EMDR among its recommended PTSD treatments.
One nuance worth knowing: some research has questioned whether the eye-movement component itself is essential to EMDR's effectiveness, versus the exposure and cognitive-reprocessing elements it shares with other trauma therapies. This doesn't undercut EMDR's overall effectiveness — reviews consistently show it works — it's more a question of which ingredient is doing the work.
Somatic additions to EMDR — whether through general somatic-informed practice or a named model like S.A.F.E. EMDR — draw on a growing body of nervous-system-focused research, including polyvagal theory. That said, some of the theoretical underpinnings, particularly certain polyvagal theory claims, remain debated within the scientific community, and body-based additions generally have a smaller independent research base than the core EMDR protocol. That doesn't mean they're ineffective — it means the formal evidence is still catching up to what many clinicians and clients report experiencing in session.
Why This Matters for Your Healing
Because the body is involved in every phase whether or not a clinician names it explicitly, working with a therapist who's trained to notice and work with those signals — rather than only the eighth-phase checklist — can make reprocessing feel more complete and less likely to leave residual physical tension behind. This is especially relevant if you:
Experience physical symptoms — chronic tension, migraines, digestive issues, fatigue — with no clear medical cause
Struggle to access clear narrative memories, which is common with early childhood or preverbal trauma
Feel disconnected from your body or notice dissociation during stress
Get easily overwhelmed or flooded by strong emotion and need a slower, more regulated pace
Start Your Healing Journey
Whether your healing path leans more cognitive, more somatic, or a blend of both, the goal is the same: helping your mind and body process what happened so it stops running the show in the present. At Myers Psychotherapeutic Services, our therapists can help you figure out which approach — or combination of approaches — fits where you are right now.
