How they work
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
Structural Dissociation
Core mechanism: Phase-oriented treatment: (1) stabilize ANP functioning and reduce EP intrusions, (2) process traumatic memories to resolve phobia of trauma-related content, (3) integrate dissociated parts into a more unified personality
Ontology: Trauma structurally divides the personality into parts organized around incompatible action systems: daily life management (ANP) and survival defense (EP); healing requires phased integration of what was dissociated

What each assumes — and misses
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?
Structural Dissociation
Philosophical roots: Janet (dissociation, fixed ideas, action systems); Myers (shell shock, apparently normal/emotional personality); Bowlby (attachment); evolutionary psychology (action systems); van der Kolk (body keeps the score)
Blind spots: Phase-oriented approach can become indefinite stabilization that avoids processing; the model is complex and requires training specifically in dissociative disorders rather than general trauma training, and is not safe to improvise without it; presentations where a simpler trauma treatment would be sufficient are a fit question rather than a safety one; may pathologize adaptive dissociation in some cultural contexts
Therapeutic voice: The part of you that goes to work and pays the bills, and the part that wakes up screaming: they're both you. Right now they don't know each other very well. Our work is to help them communicate.
Choosing between them
Sensorimotor Psychotherapy (Somatic) and Structural Dissociation (Trauma-Focused) 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.
