Peter Levine developed somatic experiencing from observing how animals in the wild metabolise threat events. Protective responses (fight, flight, freeze) cycle through and resolve when uninterrupted. In humans, social and cognitive constraints often interrupt these responses, leaving them stuck in the body as chronic autonomic activation.

The protocol works with the body's natural capacity to complete what was interrupted. The therapist tracks subtle body sensations and movements, helping the client notice what wants to happen but never did. A protective gesture. A defensive stance. A directional movement away from threat. These responses are titrated and allowed to complete in small increments.

Sessions involve far more attention to body sensation than narrative content. The work is slow and incremental. Five to fifteen sessions is typical for single-incident presentations; complex trauma often requires 6 months to 2 years.

Somatic experiencing is particularly well-suited to: trauma where the threat response was clearly interrupted (held still during attack, unable to flee, frozen), pre-verbal trauma where narrative is not available, trauma in patients with high dissociation, and trauma where standard therapies have produced limited result.

Training is rigorous. Somatic Experiencing International offers a 3-year certification programme. The protocol takes longer than EMDR but reaches material EMDR sometimes cannot. Many trauma-trained therapists use both approaches and select based on case features.
