Craniosacral Therapy vs Somatic Experiencing
A side-by-side comparison of recorded mechanisms, evidence review status, related condition topics, and philosophical roots.

How they work
Craniosacral Therapy
Core mechanism: Proposed: light-touch manipulation releases restrictions in the craniosacral system, enabling improved CNS function and release of somatically stored trauma. Actual mechanism unclear.
Ontology: The body as carrying restrictions and stored experiences accessible through subtle touch. A premise shared with other somatic approaches but with a distinct and contested theoretical framework.
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
Craniosacral Therapy
Philosophical roots: Osteopathic medicine (Still), by way of Sutherland's cranial concept, which is the direct precursor Upledger reworked; vitalist body philosophy; phenomenology of the body as intelligent and self-healing
Blind spots: Proposed mechanism lacks scientific validation; poor inter-rater reliability; limited evidence base; risk of clients substituting CST for evidence-based treatment
Therapeutic voice: You don't have to do anything here. I'm following what your body is already doing.
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
Craniosacral Therapy 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.
