Can Eye Movement Desensitization and Reprocessing (EMDR) be effective for treating Post‑traumatic Stress Disorder (PTSD) when the trauma is ongoing?

EMDR for PTSD During Ongoing Trauma

EMDR therapy is not recommended when trauma is ongoing, because the standard EMDR protocol requires stabilization of the traumatic situation before trauma processing can begin safely and effectively. 1, 2, 3

Why Ongoing Trauma Is a Contraindication

The fundamental principle underlying trauma-focused psychotherapies—including EMDR, Prolonged Exposure (PE), and Cognitive Processing Therapy (CPT)—is that trauma processing requires the traumatic event to be in the past. 1, 2 When trauma is continuing:

• Safety cannot be established, which is the essential foundation for any trauma-focused intervention. 1, 3
• Memory consolidation is disrupted by ongoing threat, preventing the adaptive processing that EMDR targets. 4
• Therapeutic gains are undermined when patients return to environments where re-traumatization occurs between sessions. 1, 3

The Critical Distinction: Complex PTSD vs. Ongoing Trauma

It is essential to distinguish between complex PTSD (multiple past traumas, emotion dysregulation, interpersonal difficulties) and ongoing trauma exposure:

• Complex PTSD with past trauma: EMDR can be initiated immediately without a prolonged stabilization phase, as emotion dysregulation and dissociative symptoms improve directly through trauma processing. 1, 2, 3
• Ongoing trauma: EMDR and all trauma-focused therapies must be deferred until the traumatic situation is resolved or the patient is removed from danger. 1, 3

The recent paradigm shift in complex PTSD treatment—abandoning prolonged stabilization phases—applies only to patients whose trauma is in the past, not to those experiencing continuing traumatization. 2, 3

What Should Be Done Instead

Immediate Priorities When Trauma Is Ongoing

1. Establish safety first: Remove the patient from the ongoing traumatic situation or implement concrete safety measures (e.g., domestic violence shelter, restraining order, workplace transfer). 1, 3

2. Provide crisis intervention and stabilization: Focus on immediate safety planning, emotion regulation skills, grounding techniques, and crisis management—not trauma processing. 1, 3

3. Address acute psychiatric symptoms: Treat severe depression, suicidality, or substance use that may interfere with safety planning. 1, 2

Once Safety Is Established

• Initiate EMDR immediately after the traumatic situation has ended and safety is secured, without requiring a prolonged stabilization phase. 1, 2, 3
• Do not delay trauma-focused therapy once safety is achieved; the evidence shows that patients with complex presentations (multiple traumas, severe comorbidities, dissociation) benefit from immediate EMDR without extended pre-treatment stabilization. 2, 3

Evidence Base for EMDR in PTSD (When Trauma Is Past)

When the traumatic situation is resolved, EMDR is strongly recommended as first-line treatment:

• The 2023 VA/DoD Clinical Practice Guideline and the American Psychological Association both recommend EMDR as a first-line trauma-focused psychotherapy for PTSD, with efficacy comparable to PE and CPT. 1, 2, 5
• 40–87% of patients no longer meet PTSD criteria after completing 9–15 sessions of EMDR. 1, 2
• EMDR is effective across diverse populations, including refugees, conflict-affected populations, first responders, and individuals with low socioeconomic status. 6, 7, 4
• More than 30 randomized controlled trials support EMDR's efficacy for PTSD in both adults and children. 4

Common Pitfalls to Avoid

• Do not confuse complex PTSD with ongoing trauma: Patients with multiple past traumas, emotion dysregulation, or dissociation can receive EMDR immediately once safety is established; ongoing trauma is a different contraindication. 2, 3
• Do not provide EMDR while the patient remains in a dangerous situation: This is clinically inappropriate and potentially harmful, as it exposes the patient to re-traumatization and undermines therapeutic progress. 1, 3
• Do not delay EMDR for prolonged stabilization once safety is achieved: The evidence shows that emotion dysregulation, dissociation, and interpersonal difficulties improve directly through trauma processing, not through extended pre-treatment stabilization. 2, 3

Practical Algorithm

Clinical Scenario	Recommended Action
Ongoing domestic violence, active combat exposure, or current abuse	Do not initiate EMDR; prioritize safety planning, crisis intervention, and removal from danger. [1,3]
Past trauma with complex presentation (multiple traumas, emotion dysregulation, dissociation)	Initiate EMDR immediately without prolonged stabilization phase. [2,3]
Past trauma with severe comorbidities (depression, substance use disorder in remission ≥3 months, borderline personality disorder)	Initiate EMDR immediately; comorbid symptoms improve alongside PTSD symptoms. [1,2,3]
Past trauma with acute suicidality, active substance dependence requiring detoxification, or current psychotic symptoms	Stabilize acute crisis first, then initiate EMDR without further delay. [3]
