Scientific research

TRE™ emerged from clinical observation and is grounded in established neuroscience. The research base continues to grow as more studies investigate its effects.

Foundational science​

TRE™ builds on well-established scientific concepts:

  • Neurogenic tremors — The therapeutic tremors activated in TRE™ are neurophysiological, generated by Central Pattern Generators (CPGs) in the spinal cord. These neural networks can produce rhythmic movement without input from higher brain centres. The tremors are categorically distinct from pathological tremors; they represent the body’s natural mechanism for releasing held tension.
  • Autonomic nervous system regulation — TRE™ helps shift the nervous system from sympathetic (fight or flight) to parasympathetic (rest and digest) dominance. This aligns with polyvagal theory, which describes how our nervous system responds to safety and threat.
  • Fascia and connective tissue — Research on the myofascial system shows that tension can be held in connective tissue throughout the body. Tremoring appears to release tension in this network.

Clinical findings​

Preliminary research shows promising results across several areas:

  • Trauma and PTSD — Studies with veterans, refugees, and other trauma-exposed populations have documented reductions in PTSD symptoms following TRE™ practice.
  • Stress and anxiety — Research with healthcare workers, students, and general populations consistently shows decreased anxiety and improved stress management.
  • Physical well-being — Studies report improvements in sleep quality, reductions in chronic muscular tension, and positive changes in heart rate variability (a marker of autonomic health).

Research limitations​

Current research has constraints typical of emerging body-based interventions:

  • Most studies involve small sample sizes
  • Randomised controlled trials are limited
  • Long-term follow-up data is sparse
  • Creating placebo controls for physical practices is challenging

These limitations don’t negate the findings; they indicate where more research is needed.
