What the research shows
The evidence base for TRE is growing but still modest compared to more established therapeutic approaches. Being honest about this matters. Overclaiming undermines the genuine promise of the work.
What the existing research suggests:
- Reduced muscle tension and pain. Several studies report significant reductions in chronic muscular tension following TRE practice, particularly in the psoas and surrounding musculature.
- Improved sleep quality. Participants in TRE studies frequently report better sleep onset, duration and quality.
- Reduced anxiety and stress markers. Both self-report measures and physiological indicators (cortisol, heart rate variability) show improvements with regular practice.
- Improved quality of life. Studies with military personnel, first responders and people living in conflict-affected areas report improvements in overall wellbeing and functioning.
Key studies
Research on TRE has been conducted in several countries and contexts. Key findings include:
- Studies with military veterans showing reduced PTSD symptoms and improved emotional regulation after TRE programmes
- Research with healthcare workers showing reduced burnout symptoms and improved resilience
- Studies in post-conflict communities pointing to TRE's potential as a low-cost, scalable intervention for mass trauma
- Pilot studies on chronic pain populations reporting reduced pain intensity and improved function

What the evidence doesn't yet prove
Transparency matters. The current limitations include:
- Sample sizes are generally small
- Many studies lack randomised controlled trial (RCT) design
- Long-term follow-up data is limited
- The mechanism of action is theorised but not yet fully established
- There's a lack of comparison studies with other somatic approaches
This doesn't mean TRE doesn't work. Clinical observation and practitioner experience are consistent and compelling. But the formal evidence base hasn't yet caught up with the practice.
David Berceli's background
TRE was developed by Dr David Berceli, PhD, who has spent over two decades working with trauma-affected communities in Africa, the Middle East and Asia.
Berceli's insight came from observing how people's bodies responded to sustained threat: the chronic bracing, the suppression of natural tremoring and the lasting physical effects. He developed TRE as a simple, teachable method that could be used at scale, particularly in communities without access to individual therapy.
TRE in context
TRE is increasingly used in:
- Clinical settings: as an adjunct to psychotherapy, physiotherapy and trauma treatment
- Organisations: for staff wellbeing, particularly in high-stress environments (military, emergency services, healthcare)
- Communities: as a scalable, low-cost intervention in post-disaster and post-conflict settings
- Personal practice: as an ongoing self-care tool
An emerging field
The honest position: TRE is a promising somatic practice with a strong theoretical basis, consistent clinical observations and a growing but still limited formal evidence base. It's worth taking seriously, and worth being rigorous about what we know and don't know.
