Reviewed by the BilateralSync clinical team · Updated · 6 min read

Introduction

EMDR is recommended as a first-line psychotherapy for post-traumatic stress disorder (PTSD) by the World Health Organization, the American Psychological Association, the International Society for Traumatic Stress Studies and the UK NICE guideline (NG116). It is one of two trauma-focused therapies (alongside trauma-focused CBT) with the strongest evidence base.

Evidence summary

Meta-analyses of RCTs consistently show large effect sizes for EMDR in adult PTSD, comparable to trauma-focused CBT and superior to waitlist and non-trauma-focused active controls. Effects appear stable at follow-up.

Clinical use

For PTSD, EMDR follows the standard eight-phase protocol with target selection guided by the client's trauma history. Careful preparation (Phase 2), resourcing, and window-of-tolerance management are especially important. Complex PTSD often requires additional stabilization and a phase-oriented approach.

Frequently asked questions

How many EMDR sessions does PTSD treatment typically take?
For single-incident adult PTSD, 6–12 sessions is common. Complex or multiple-trauma presentations typically require longer, phased treatment.
