Both work with trauma at the level of the nervous system rather than just the narrative. Here’s how they differ and how to choose.
If you’ve been looking into therapy for trauma, anxiety, or nervous system dysregulation, you’ve probably come across both Somatic Experiencing and EMDR. Both have strong research support. Both work with trauma at a physiological level rather than just at the level of story and cognition. And both are meaningfully different from standard talk therapy in ways that matter if you’ve tried talk therapy and found it helpful but insufficient.
The question of which one to pursue is worth thinking through carefully, because they work differently, suit different people, and have different practical considerations around availability and cost.
What they have in common
Before getting into the differences, it’s worth being clear about what Somatic Experiencing and EMDR share, because it’s significant.
Both approaches recognise that trauma is stored in the body and nervous system, not just in memory and narrative. Both work with the physiological dimension of traumatic experience rather than treating it purely as a cognitive or emotional problem. Both have moved away from the idea that extensively narrating or revisiting traumatic events is necessary or always helpful for healing. And both have accumulated enough research support to be considered evidence-based approaches rather than alternative therapies.
This shared foundation means that either approach is likely to go further for trauma than purely cognitive or talk-based therapy for many people, especially those who have found that understanding their patterns intellectually hasn’t changed how they feel or behave in the ways they were hoping for.
Somatic Experiencing
Somatic Experiencing was developed by Peter Levine, whose observation that animals in the wild don’t develop lasting trauma symptoms despite regular life-threatening experiences led him to the insight that trauma is an incomplete biological response rather than a psychological wound.
The core idea is that when a threat is experienced, the nervous system mobilises energy for fight or flight. If that response can’t complete, whether because the threat was inescapable, overwhelming, or because social context prevented full expression, the mobilised energy remains in the nervous system as unfinished business. Trauma symptoms, chronic activation, hypervigilance, shutdown, physical symptoms, are the nervous system’s ongoing attempt to manage this incomplete response.
SE works by gradually and gently helping the nervous system complete the responses that trauma interrupted. The therapist tracks the client’s physiological state carefully, working with body sensation, movement impulses, and autonomic activation. The approach is titrated, meaning it moves in small steps, regularly returning to regulated states rather than pushing into full re-experiencing of traumatic material.
Sessions typically involve a lot of attention to present-moment body sensation: noticing where tension lives, what happens when you track a physical sensation, how the body wants to move or express something it wasn’t able to at the time. There’s usually relatively little explicit narration of traumatic events, particularly in the early stages.
SE tends to suit people who:
- Are comfortable working with body sensation and internal experience
- Have found talk therapy helpful for understanding but not for changing how they feel physically
- Are dealing with trauma that feels more physical or somatic than narrative — chronic pain, autonomic dysregulation, shutdown states
- Prefer a slower, more gradual approach
- Are working with pre-verbal or early developmental trauma where there isn’t a clear narrative to work with
EMDR
EMDR, Eye Movement Desensitisation and Reprocessing, was developed by Francine Shapiro in the late 1980s. The original observation was that bilateral eye movements while recalling distressing memories appeared to reduce their emotional charge. The approach has been refined considerably since then and is now one of the most researched trauma therapies available, with strong support from bodies including the WHO and the American Psychological Association.
The bilateral stimulation component, which can be eye movements, alternating taps, or alternating sounds, is thought to engage both hemispheres of the brain simultaneously in a way that facilitates the processing and integration of traumatic memories. The current leading explanation draws on the Adaptive Information Processing model, which proposes that trauma produces maladaptively stored memories that haven’t been fully integrated, and that bilateral stimulation during recall helps the brain process and integrate them.
EMDR is more structured than SE. It follows a specific eight-phase protocol, involves more explicit engagement with traumatic memories, and typically produces more rapid symptom reduction in controlled trials. Sessions often involve recalling specific traumatic memories or the negative beliefs associated with them while the bilateral stimulation is applied.
EMDR tends to suit people who:
- Have specific traumatic memories or events they want to process
- Are comfortable accessing and holding traumatic material in a structured way
- Want a faster-moving approach with more measurable progress on specific memories
- Are dealing with single-incident trauma or PTSD with clear precipitating events
- Have a stable enough baseline to engage with traumatic material directly
Key differences in practice
The most practically significant difference is in how directly each approach engages with traumatic memory content.
EMDR works with specific memories relatively directly. You’ll typically identify target memories early in the process, access them during sessions, and notice how they shift over time. For people with clear, identifiable traumatic events, this directness is often efficient and effective.
SE is more indirect. Rather than targeting specific memories, it tracks what’s happening in the nervous system in the present moment and follows the body’s process. Traumatic material may emerge, but it’s worked with through sensation and impulse rather than through narrative recall. This makes SE generally considered better tolerated for people with complex or developmental trauma, where direct engagement with traumatic material can be destabilising.
The other significant practical difference is availability. EMDR practitioners are more widely available than SE practitioners in most areas, and EMDR is more commonly offered through general therapy practices and online platforms. Online-Therapy.com has EMDR-trained therapists available, which removes the barrier of finding a specialist locally. Use code THERAPY20 for 20% off.
SE practitioners require specific training that is less common, and finding a well-trained SE therapist may take more searching depending on where you’re located.
Which to choose
There’s no universal answer, and for many people either approach would be beneficial. A few considerations that might help:
If you have complex or developmental trauma, significant dissociation, or a history of being destabilised by accessing traumatic material directly, SE’s more gradual, titrated approach is generally considered safer and better tolerated.
If you have specific traumatic events you want to process and feel stable enough to engage with them in a structured way, EMDR’s efficiency and wider availability make it a strong first choice.
If access and cost are significant factors, EMDR’s greater availability online and through general therapy practices makes it more accessible in most circumstances.
If you’ve tried EMDR and found it too activating or not quite right, SE is a natural next step. If you’ve tried SE and want something more structured and faster-moving, EMDR is worth exploring.
For reading before making a decision, Peter Levine’s Waking the Tiger gives the clearest account of the SE approach and the theory behind it. Francine Shapiro’s Getting Past Your Past does the same for EMDR and is written for a general rather than clinical audience.
A note on therapist quality
With both approaches, the quality and experience of the individual therapist matters as much as the modality. A skilled SE practitioner and a skilled EMDR practitioner will both likely produce good outcomes. A poorly trained practitioner in either modality can be unhelpful or, in the case of trauma work, actively harmful.
When looking for a practitioner, ask about their specific training in the approach, how many clients they’ve worked with using it, and whether they have experience with your particular presentation. For SE, the Somatic Experiencing International directory is a reliable source of trained practitioners. For EMDR, the EMDR International Association directory serves the same function.
