What is EMDR? Complete Guide to Eye Movement Desensitization and Reprocessing

A comprehensive resource for therapists on EMDR therapy: understanding the theory, 8-phase protocol, bilateral stimulation, and practical applications in trauma treatment.

Understanding EMDR Therapy

Eye Movement Desensitization and Reprocessing (EMDR) is an evidence-based psychotherapy approach developed by Francine Shapiro in the late 1980s. Originally designed to treat trauma and PTSD, EMDR has since been adapted for a wide range of conditions.

EMDR is based on the Adaptive Information Processing (AIP) model, which posits that trauma and other adverse experiences can overwhelm the brain's natural information processing system, causing memories to be stored dysfunctionally with their original emotions, physical sensations, and beliefs intact.

Through bilateral stimulation (eye movements, taps, or sounds) while the client focuses on traumatic memories, EMDR helps the brain reprocess these memories, allowing them to be stored adaptively with reduced emotional charge.

Core Principles of EMDR

Adaptive Information Processing Model

The AIP model suggests that the brain has an innate capacity to process and integrate experiences adaptively. When this system is overwhelmed (as in trauma), memories remain unprocessed and can be triggered by current events.

Bilateral Stimulation

Bilateral stimulation (eye movements, taps, or sounds) appears to activate the brain's information processing system, allowing traumatic memories to be reprocessed and integrated adaptively.

Dual Attention

Clients maintain dual attention: focusing on the traumatic memory while simultaneously engaging in bilateral stimulation. This dual focus appears to facilitate processing.

Client-Centered Processing

Unlike talk therapy, EMDR doesn't require extensive discussion of trauma details. The client's own brain does the healing work, with the therapist as a guide.

The 8-Phase EMDR Protocol

Phase 1: History Taking and Treatment Planning

Therapist gathers comprehensive history, identifies targets for processing (past events, current triggers, future templates), and develops a treatment plan. This phase includes assessing client readiness and stability.

Phase 2: Preparation

Therapist explains EMDR, establishes rapport, and teaches stabilization and self-control techniques. Key elements include:

  • Safe place/calm place installation
  • Resource development and installation (RDI)
  • Container technique for managing distress
  • Explanation of the process and what to expect
  • Assessment of client's window of tolerance

Phase 3: Assessment

For each target memory, therapist identifies:

  • Image: The worst part of the memory
  • Negative Cognition (NC): The negative self-belief (e.g., "I am powerless")
  • Positive Cognition (PC): The desired positive belief (e.g., "I am capable")
  • Validity of Cognition (VOC): How true the PC feels (1-7 scale)
  • Emotions: Current emotions when thinking of the memory
  • Subjective Units of Disturbance (SUD): Distress level (0-10 scale)
  • Body Sensations: Where the disturbance is felt physically

Phase 4: Desensitization

Client focuses on the target memory while engaging in bilateral stimulation (sets of eye movements, taps, or sounds). After each set, client reports what comes up. Processing continues until SUD reaches 0 or 1 (or as low as possible). This phase allows the memory to be processed and desensitized.

Phase 5: Installation

The positive cognition is strengthened and "installed" using bilateral stimulation until the VOC reaches 7 (completely true). This phase links the positive belief with the processed memory.

Phase 6: Body Scan

Client scans their body for any residual tension or disturbance while holding the target memory and positive cognition. Any remaining sensations are processed with additional bilateral stimulation.

Phase 7: Closure

Session ends with stabilization techniques. If processing is incomplete, therapist uses container or safe place to help client return to a stable state. Client is debriefed and given instructions for between-session self-care.

Phase 8: Re-evaluation

At the start of each new session, therapist checks on the previously processed target. SUD and VOC are re-assessed, and any new material that has emerged is addressed. This ensures processing is complete and stable.

Bilateral Stimulation Methods

Eye Movements

The original and most common method. Therapist moves fingers or a light bar horizontally while client follows with their eyes. Typically 20-30 movements per set.

Tactile Tapping

Alternating taps on client's hands, knees, or using handheld buzzers. Useful when eye movements are difficult or for clients who prefer tactile stimulation.

Auditory Tones

Alternating sounds through headphones. Less commonly used but effective for clients who cannot use eye movements or tapping.

Applications and Effectiveness

EMDR has strong research support and is recognized as an effective treatment for:

Primary Applications

PTSD, Trauma, Acute Stress Disorder, Complex Trauma, Childhood Trauma, Single-incident trauma

Adapted Applications

Anxiety disorders, Depression, Phobias, Panic disorder, Grief and loss, Performance anxiety, Addictions

Research shows EMDR is as effective as trauma-focused CBT for PTSD, often with fewer sessions. It's recognized by the World Health Organization, American Psychiatric Association, and Department of Veterans Affairs as an effective treatment for trauma and PTSD.

Implementing EMDR in Your Practice

Proper Training: EMDR requires specialized training from an EMDRIA-approved trainer. Basic training is typically 20 hours plus 10 hours of consultation. Advanced training is available for complex cases.

Client Preparation: Ensure clients have adequate stabilization and coping skills before processing trauma. Use Phase 2 extensively with complex trauma clients.

Target Development: Develop a comprehensive target sequence plan addressing past events, current triggers, and future templates. Process past events before current triggers.

Following the Protocol: Adhere to the 8-phase protocol. While adaptations exist, the standard protocol should be followed unless there's a clear clinical rationale for modification.

Safety and Stabilization: Always ensure proper closure. If processing is incomplete, use stabilization techniques. Monitor client's window of tolerance throughout.

Training and Certification

EMDR requires specialized training. The EMDR International Association (EMDRIA) sets training standards. Training typically includes:

  • Basic EMDR training (20 hours didactic + 10 hours consultation)
  • Understanding the AIP model and 8-phase protocol
  • Practice with bilateral stimulation methods
  • Case conceptualization and target development
  • Working with complex trauma and adaptations
  • Ongoing consultation and continuing education

Certification is available through EMDRIA. Ongoing consultation and adherence to the protocol are essential for effective and ethical EMDR practice.

Limitations and Considerations

EMDR has specific requirements and considerations:

  • Requires specialized training and ongoing consultation
  • Clients must have adequate stabilization before processing trauma
  • May not be suitable for clients with severe dissociation or psychosis
  • Complex trauma may require extended preparation and processing
  • Some clients may find bilateral stimulation uncomfortable
  • Processing can be intense and may bring up unexpected material
