EMDR vs Somatic Therapy: What's the Difference?

EMDR works primarily through bilateral stimulation to help the brain reprocess specific traumatic memories. Somatic therapy works through body awareness and nervous system regulation, focusing less on individual memories and more on the patterns of activation that trauma leaves in the body.

Both are considered trauma-informed, and both go well beyond traditional talk therapy. But they are quite different in how they work, what they target, and what kinds of experiences they tend to be best suited to. If you are trying to figure out which one might be right for you, it helps to understand what each is actually doing.

Key Takeaways

• EMDR uses bilateral stimulation (eye movements, tapping, or sounds) to help the brain reprocess specific distressing memories.

• Somatic therapy works with body sensation and nervous system patterns rather than memory content.

• EMDR tends to be more structured and protocol-driven. Somatic therapy tends to be more emergent and relational.

• Both can be effective for trauma. The better fit often depends on the nature of the trauma and what the person is actually experiencing.

• They are not mutually exclusive. Some therapists integrate elements of both.

How EMDR works

EMDR, which stands for Eye Movement Desensitization and Reprocessing, was developed by Francine Shapiro in the late 1980s. It uses bilateral stimulation, typically side-to-side eye movements, but also tapping or alternating sounds, while the client holds a specific memory in mind. The bilateral stimulation is thought to activate the same brain processes that happen during REM sleep, allowing the memory to be reprocessed and stored differently.

EMDR follows a structured eight-phase protocol. Sessions involve identifying target memories, assessing the distress associated with them, working through them with bilateral stimulation, and then installing a more adaptive belief to replace the distorted one associated with the memory. It is relatively structured compared to most trauma approaches.

How somatic therapy works

Somatic therapy operates on a different premise. Rather than targeting specific memories, it works with what trauma leaves in the body: the patterns of tension, bracing, collapse, and dysregulation that develop when the nervous system has been chronically overwhelmed. The focus is less on what happened and more on what is happening now, in the body, as a result of what happened.

Sessions in somatic therapy involve tracking body sensations, working with the impulses and responses that did not get to complete at the time of the overwhelming experience, and gradually expanding the nervous system's capacity to tolerate a wider range of activation. The work is slower, more moment-to-moment, and less structured than EMDR.

What each tends to be better suited to

EMDR tends to work particularly well for single-incident trauma, situations where something specific happened and that memory is still activating distress. A car accident, a medical procedure, an assault, one identifiable experience that left something unprocessed. The protocol is built around working with discrete memories, and it can produce relatively fast results when there is a clear target.

Somatic therapy tends to be better suited to complex or relational trauma, the kind that does not come from one event but from chronic conditions over time. Neglect, emotional unavailability, growing up in an unpredictable environment, years of not being seen or safe. This kind of trauma does not organize itself into discrete memories with the same clarity. It lives in the body as a general state rather than in specific recollections.

What about emotional numbness and disconnection

If emotional numbness, dissociation, or a general sense of disconnection are central to what you are experiencing, somatic therapy is often the more direct route. These experiences are nervous system responses, and working with them requires engaging the nervous system directly. EMDR can reach some of this, but it requires enough nervous system stability to process memories, and if that stability is not there, the protocol needs modification.

Somatic approaches are designed to build that stability first, and to work with dissociation as part of the therapeutic material rather than as an obstacle to overcome before the real work begins.

When they get combined

A number of therapists integrate somatic and EMDR approaches. Some use somatic work to prepare the nervous system for EMDR processing. Others use bilateral stimulation within a more somatic framework. The two are not incompatible, and for some people the combination is more effective than either approach alone.

It is worth asking a potential therapist about how they actually integrate different approaches rather than assuming that because someone lists multiple modalities they are genuinely integrating them in a sophisticated way.

How to figure out which might be right for you

A few questions worth sitting with: Is there a specific memory or event at the center of your distress, or is it more of a chronic background state? Do you feel mostly in your body or mostly disconnected from it? Are you looking for something more structured and protocol-driven, or more relational and emergent? A good therapist who does an initial assessment should be able to help you think through the fit.

Is EMDR or somatic therapy better for PTSD?

Both have evidence supporting their use for PTSD, and both are trauma-informed approaches recommended in clinical guidelines. EMDR has more standardized research behind it due to its structured protocol. Somatic approaches have a strong clinical evidence base particularly for complex PTSD. The better fit depends on the nature and history of the trauma, not on one being categorically superior.

Can you do EMDR and somatic therapy at the same time?

Yes, and some therapists are trained in both and integrate them deliberately. If you are working with different therapists on each, communication between them is important to ensure the work is coherent rather than pulling in different directions.

Does somatic therapy involve touch?

Not necessarily. Many somatic therapists work entirely through verbal guidance and body awareness, without any physical touch. Some somatic modalities, like Somatic Experiencing, are typically touch-free. Others may include touch as an option with explicit consent. It is a good question to ask any therapist before starting.

How do I find a somatic therapist in Ontario?

Look for therapists who list somatic therapy, Somatic Experiencing, sensorimotor psychotherapy, or body-based trauma work among their approaches. In Ontario, Registered Psychotherapists are regulated by the College of Registered Psychotherapists of Ontario, so you can verify credentials through their public register. Ask during a consultation about their specific training in somatic work.
