EMDR Therapy for PTSD: How It Works and What to Expect
EMDR therapy for PTSD explained: the 8 phases, how bilateral stimulation works, research evidence, what sessions feel like, how many sessions you need and online EMDR.

EMDR (Eye Movement Desensitization and Reprocessing) is an evidence-based therapy for PTSD. While briefly focusing on a traumatic memory, you follow bilateral stimulation (side-to-side eye movements, taps or tones) guided by a trained therapist. This helps the brain reprocess the memory so it becomes less vivid and distressing. EMDR follows 8 phases and often takes 6 to 12 sessions for a single trauma.
Key takeaways
- EMDR is recommended for PTSD by the WHO, VA/DoD and other guidelines.
- It requires less detailed talking about the trauma than some therapies.
- There is usually no homework between sessions.
- Single-incident trauma often improves in 6 to 12 sessions.
- EMDR can be delivered effectively online.
Talking about trauma in detail can feel impossible. EMDR offers a different path: you focus on the memory only briefly while your brain processes it with the help of eye movements or taps. Many people are skeptical at first, then surprised by how much lighter the memory feels afterward.

How EMDR works
EMDR was developed by psychologist Francine Shapiro in the late 1980s. According to the adaptive information processing model, traumatic memories can be stored in an unprocessed way, so reminders trigger the original emotions and body sensations. Bilateral stimulation while recalling the memory appears to tax working memory and help the brain integrate it with more adaptive information, reducing its emotional charge.

The 8 phases of EMDR
History and planning
Identifying target memories and goals.
Preparation
Building trust and coping skills such as a “calm place” exercise.
Assessment
Choosing an image, negative belief, desired positive belief, emotions and body sensations.
Desensitization
Sets of bilateral stimulation while focusing on the memory.
Installation
Strengthening the positive belief.
Body scan
Checking for remaining tension.
Closure
Returning to calm at the end of each session.
Reevaluation
Reviewing progress at the next session.
Does EMDR work?
Yes. Multiple randomized trials and meta-analyses show EMDR is effective for PTSD, with outcomes comparable to trauma-focused CBT approaches. It is recommended in guidelines from the World Health Organization, the VA/DoD and others.
EMDR vs other PTSD therapies
| EMDR | CPT | Prolonged exposure | |
|---|---|---|---|
| Talking about trauma | Brief focus, less detail | Discussion of beliefs; optional written account | Detailed retelling |
| Homework | Minimal | Worksheets | Exposure practice |
| Typical sessions | 6 to 12 | About 12 | 8 to 15 |
What EMDR sessions feel like
Sessions last 60 to 90 minutes. During processing, emotions or memories may surface and shift; your therapist checks in between sets and you can stop at any time. Some people feel tired or emotional after sessions. Over time, the memory usually feels more distant and less intense.
