How they work
EMDR
Core mechanism: Bilateral stimulation during trauma memory processing facilitates adaptive information processing and memory reconsolidation (proposed)
Ontology: Unprocessed trauma memories stored dysfunctionally with original affect, sensation, and cognition
Sensorimotor Psychotherapy
Core mechanism: Mindful tracking of sensorimotor experience reveals trauma-encoded body patterns; completing interrupted defensive responses and discovering new physical actions reorganizes both body and meaning
Ontology: Trauma is encoded in the body as incomplete sensorimotor sequences and procedural patterns that repeat automatically; the body is a primary information processing system, not merely a container for psychological content

What each assumes — and misses
EMDR
Philosophical roots: Merleau-Ponty (body holds memory); Bion (processing/containment); Pavlov (orienting response); Shapiro (adaptive information processing — pragmatic, not philosophically derived)
Blind spots: Mechanism debate unresolved; protocol fidelity varies; may be applied to conditions beyond its evidence base
Therapeutic voice: Bring up the image and the negative belief. Notice what you feel in your body. Now follow my fingers.
Sensorimotor Psychotherapy
Philosophical roots: Ogden (body as primary processor); Kurtz (Hakomi — mindfulness in therapy); Siegel (window of tolerance, interpersonal neurobiology); van der Kolk (body keeps the score); Piaget (sensorimotor intelligence); Bowlby (attachment); Janet (action systems)
Blind spots: Limited RCT evidence compared to PE or CPT; training is expensive and lengthy; body-focused work requires careful titration for highly dissociative clients; lacks the manualized structure that makes protocols teachable
Therapeutic voice: I notice your shoulders just pulled up toward your ears when you mentioned your mother. Can you stay with that? What wants to happen in your body right now?
Choosing between them
EMDR (Trauma-Focused) and Sensorimotor Psychotherapy (Somatic) come from different traditions, which means they assume different things about what a person is, what causes suffering, and what the therapeutic relationship is for. The choice between them is often less about "which works better" and more about which set of assumptions fits the client and the therapist.
