How they work
Polyvagal-Informed Therapy
Core mechanism: Identifying autonomic state (ventral/sympathetic/dorsal) + co-regulation with therapist + building ventral vagal capacity
Ontology: Trauma disrupts autonomic regulation; neuroception of danger keeps nervous system in defensive states
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
Polyvagal-Informed Therapy
Philosophical roots: Porges (polyvagal theory); Darwin (emotional expression); Merleau-Ponty (body-subject); Dana (clinical application); Levine (somatic trauma)
Blind spots: Underlying theory scientifically contested; clinical applications extrapolate beyond evidence; not a standalone protocol
Therapeutic voice: That shutdown feeling — that's your nervous system protecting you. It makes sense. Let's see if we can find a little more safety right now.
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
Polyvagal-Informed Therapy 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.
