How they work

NARM

Core mechanism: Simultaneously tracking somatic experience, relational patterns, and identity-level beliefs reveals how developmental survival styles organized around early unmet needs are maintained in the present

Ontology: Early attachment failures create survival styles that organize identity, relationships, and somatic patterns into predictable configurations; the self-structure formed around deprivation, not the original events, is what maintains suffering

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

NARM

Philosophical roots: Heller (developmental trauma and identity); Levine (Somatic Experiencing, where Heller trained and taught before developing NARM); Reich (character armor, reimagined developmentally); Bowlby (attachment); Schore (affect regulation); Winnicott (true self/false self); Lowen (bioenergetics, reframed)

Blind spots: Limited empirical evidence; five survival styles risk becoming rigid typology; developmental focus may not address acute symptom presentations; less helpful for single-incident trauma

Therapeutic voice: You're telling me about this pattern of always taking care of others. As you say that, what do you notice happening in your body? And I'm curious: what happens inside when you imagine someone wanting to take care of you?

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

NARM and Sensorimotor Psychotherapy both sit within the Somatic tradition — they share a worldview about what suffering is and how change happens. Differences are more often about technique and emphasis than about underlying theory.
