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

Somatic Experiencing

Core mechanism: Alternating in small doses between activation and a settled resource state ('pendulation') is held to complete defensive responses that were interrupted at the time of the threat and remain bound in the body

Ontology: Incomplete defensive responses (fight/flight/freeze) remain bound in the nervous system as undischarged survival energy

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?

Somatic Experiencing

Philosophical roots: Reich/Lowen (body holds defense; Levine worked in this lineage but did not study with Reich, who died in 1957); Merleau-Ponty (lived body); Darwin (survival instincts); ethology (Tinbergen, Lorenz: animal defensive responses); James-Lange (emotion as bodily process)

Blind spots: Risk of over-physiologizing psychological meaning; limited manualization makes research difficult; can be vague in application

Therapeutic voice: Let's leave that where it is for a moment and come back to your feet on the floor. When you're ready we'll go back and take a smaller piece of it.

Choosing between them

Sensorimotor Psychotherapy and Somatic Experiencing 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.
