TRE™ vs Somatic Experiencing: What Is the Difference?

Somatic Experiencing® is a body-oriented approach to stress and trauma developed by Dr Peter Levine. In sessions, a trained practitioner helps you notice physical sensations and work with small, manageable amounts of activation, so the nervous system can gradually settle. It is usually one-to-one, and many practitioners are therapists or counsellors.

Levine developed the approach from studying stress physiology and from observing that wild animals, though often under threat, rarely seem to stay stuck in it. He described it in his 1997 book Waking the Tiger. Practitioners train through a multi-year professional programme and use the title Somatic Experiencing Practitioner (SEP).

Key SE ideas include tracking (noticing sensations as they change), titration (approaching difficult material a little at a time) and pendulation (moving between activation and a sense of ease). Sessions mostly involve guided attention and conversation; some practitioners also use touch.

The main difference is who leads. SE is a guided process: a trained practitioner works with you, session by session, often around specific experiences. TRE™ is a skill you learn: after a few guided sessions you practise the exercises yourself. SE relies mainly on guided attention to body sensation; TRE™ relies mainly on movement and the tremor reflex.

• Origins: SE was developed by Dr Peter Levine; TRE™ by Dr David Berceli.
• Format: SE is usually one-to-one with a practitioner; TRE™ can be taught one-to-one, in groups or online, and is then practised alone.
• Method: SE uses guided attention to sensation, in small steps; TRE™ uses simple exercises that invite a natural tremor.
• Talking: SE includes conversation, though you are not asked to relive events in detail; TRE™ needs no talking about the past.
• Independence: SE usually unfolds over a series of practitioner-led sessions; TRE™ is designed to become a self-help practice after 3–4 guided sessions.

Both share a core idea: stress and trauma affect the body as well as the mind, and the nervous system can move back towards balance when it is given safety and time.

Yes. TRE™ is a self-help practice, and many people use it alongside therapy, coaching or medical care. If you already work with an SE practitioner or therapist, let them know you would like to try TRE™, and tell your TRE™ provider about your therapy, so that the two support each other.

This matters most if you have a history of complex trauma or dissociation. In that case, speak to your therapist before you start, keep tremor periods short, and learn with a certified provider rather than from videos. See Is TRE™ safe?
