How they work
Somatic Experiencing
Core mechanism: Titrated pendulation between activation and resource states completes truncated survival responses trapped in the body
Ontology: Incomplete defensive responses (fight/flight/freeze) remain bound in the nervous system as undischarged survival energy
Trauma-Sensitive Yoga
Core mechanism: Repeated practice of noticing and making choices about physical experience within a safe relational context restores interoceptive awareness and the capacity for self-regulation that trauma disrupts
Ontology: Trauma as disruption of the body's capacity to be inhabited safely. Healing requires restoring the relationship to bodily experience through titrated, choice-based somatic practice.

What each assumes — and misses
Somatic Experiencing
Philosophical roots: Reich/Lowen (body holds defense — Levine studied with both); 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: Where in your body do you feel that right now? Just notice, without trying to change it.
Trauma-Sensitive Yoga
Philosophical roots: van der Kolk (body keeps the score); Merleau-Ponty (embodied subjectivity); Levine (somatic experiencing); Porges (polyvagal theory)
Blind spots: Certification standards vary; quality of instruction is highly variable outside certified programs; not a standalone treatment; limited RCT replication
Therapeutic voice: Notice if there's anything happening in your body right now. You might try this shape, or something else entirely, or just stay still. Whatever works for you.
Choosing between them
Somatic Experiencing and Trauma-Sensitive Yoga 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.
