The most common clinical error in EMDR is not a bad protocol. It's running a technically flawless protocol on a client who wasn't ready.
The tri-phasic model.
Every major trauma treatment framework uses the same three-phase structure. Different names, different emphases, same architecture: stabilize first, process second, integrate third. This is not one school's opinion. It is the consensus of the field.
The uncomfortable truth.
I have seen it more times than I can count. A clinician who learned EMDR correctly, followed the protocol faithfully, and destabilized their client anyway. Not because they did the protocol wrong. Because they skipped the part that actually matters: making sure the client's nervous system could hold what they were asking it to do.
The client came in the next week flooded. Or dissociated. Or didn't come back at all. Or ~ the worst version ~ came back and said they were fine while clearly not being fine, because they had learned that falling apart in session was not safe.
What stabilization looks like.
Stabilization is not a waiting room for the real work. It is the real work. Here is what it actually involves:
Clients who understand what is happening in their body are less afraid of it. Window of tolerance, polyvagal theory, the difference between a trauma response and a character flaw. This is not preliminary. It is therapeutic.
Teaching the client to recognize their state and shift it. The toolkit below is not a handout ~ it is a clinical intervention. You teach it, you practice it in session, you troubleshoot it.
Calm/safe place, container, inner advisor, nurturing/protective figures. Installed with short ABLS sets. Not optional. Not a warm-up. The resource is what the client uses when the processing gets hard.
Building the therapeutic alliance explicitly. Naming what is happening between you. Repairing ruptures. Practicing co-regulation. The relationship is the intervention.
Mapping the internal system. Who's here? What do they need? What are they protecting? You cannot process a memory that belongs to a part who doesn't trust you yet. The relationship with the part comes first.
Using your own regulated nervous system to help regulate theirs. This is half of what we actually do, and we almost never talk about it. Your calm is contagious ~ if they can borrow it.
Everything I thought was just setup ~ the part we had to get through to get to "the trauma" ~ was the trauma work. Grounding. Resourcing. Relationship. Stabilization. It's not preliminary to trauma therapy. It IS trauma therapy.
Five readiness domains.
Before you target a memory, you need honest answers to five questions. Not reassuring answers. Honest ones.
Can the client tolerate distress without flooding or shutting down?
The client can notice difficult emotions and body sensations without immediately dissociating, acting out, or collapsing. They have at least one reliable self-regulation strategy. They can return to baseline within the session.
Is there enough therapeutic alliance to do the work?
The client can tolerate the intimacy of trauma work with you specifically. They can repair ruptures. They can use you as a co-regulator. Without this, you are processing alone while they watch.
Is the client's external world stable enough to hold the work?
Active domestic violence, homelessness, untreated severe addiction, or ongoing abuse are not contexts for trauma processing. The container has to hold. If the outside is in crisis, the inside cannot integrate.
Do you know the system you're working with?
Undetected dissociative disorders are the most common cause of destabilization in EMDR. Screen before you process. If there are parts, know who they are and whether they consent. The MID and DES-II are on the Screenings page.
Does the client have enough internal and external support?
At minimum: one safe person outside therapy, one reliable calming strategy, one place in the body that feels neutral or safe. Resourcing is not a warm-up. It is the work.
Signs of approaching readiness.
Readiness is not a binary. It is a direction. These are the signs you are moving toward it.
The client can stay present with difficult material without flooding or shutting down. Not comfortable ~ present.
When you offer a grounding or calming intervention, it works. The client can access it without extensive coaching.
The therapeutic relationship can survive a misattunement. The client can tell you when something didn't land right.
After activation, the client can return to window of tolerance within the session. Not immediately ~ within the session.
The client has language for what's happening inside. Not just 'I feel bad' ~ some differentiation between states.
The client is interested in understanding their own system, not just in having someone fix it.
Red flags: stop here.
These are not "proceed with caution" situations. They are contraindications. If any of these are present, stabilize first. Do not process.
Stabilize the crisis first. Trauma processing is not crisis intervention.
Bilateral stimulation can intensify psychotic symptoms. Contraindicated.
Processing requires the capacity to tolerate affect. Active intoxication or withdrawal removes that capacity.
You cannot process a threat that is still present. Safety first is not a cliché.
Processing without knowing the system can destabilize parts who weren't consulted. Screen first.
If the client floods or shuts down at the mention of the target, they are not ready. Build the window.
You are not a protocol delivery system. If the relationship isn't there, the work won't hold.
Regulation toolkit.
What follows is a toolkit ~ not a prescription. Different nervous systems respond to different interventions. Your job is to help clients find what works for their system, not to march them through every technique in order. Match the intervention to the state.
Use when the client is activated, anxious, hypervigilant, or stuck in fight/flight.
Use when the client is numb, dissociated, foggy, collapsed, or stuck in dorsal vagal shutdown. The goal is gentle activation ~ bringing them back into the window of tolerance from below.
Use to bring attention to the present moment and establish safety in the here-and-now. Good for both activation and shutdown ~ they bring the nervous system toward the middle.
These practices use touch and rhythm to activate the social engagement system and provide the kind of soothing that originally comes from safe others.
This page draws on Curran, L. A. (2025). Stabilization & Readiness Assessment: The Therapy Before the Therapy. The paper makes the clinical and ethical case for treating stabilization not as a preliminary step to trauma therapy but as trauma therapy itself ~ with a five-domain readiness framework, seven hard contraindications, and a complete nervous system regulation toolkit.
