What Is EMDR Therapy?
EMDR (Eye Movement Desensitization and Reprocessing) is an evidence-based trauma therapy developed in 1987 by Francine Shapiro. EMDR therapy uses bilateral stimulation—such as guided eye movements, tapping, hand buzzers, or tones—to help the brain reprocess and properly store traumatic memories, reducing their emotional intensity. EMDR mimics aspects of REM sleep, which is when our brains naturally process memories and information. Think of your brain as having a filing system. Over time, experiences get stored in folders that help shape your internal narrative. Trauma, however, can disrupt that filing system. Imagine a stack of files scattered and unorganized. Some contain outdated information tied to an old narrative about yourself—perhaps one formed during a painful or overwhelming experience. Newer, more accurate information may exist, but it doesn’t get fully integrated. The older narrative takes precedence, and the new evidence doesn’t get stored where it belongs. Normally, during REM sleep, those files get sorted and organized. But trauma can cause certain memories to become “stuck,” leaving you with conflicting internal messages. For example: Have you ever felt like a failure even though you know you’ve been successful many times? That disconnect can reflect older, unprocessed information overriding present-day reality. EMDR therapy has been researched for decades. The first clinical trial was conducted in 1989, and today EMDR is widely used to treat trauma, PTSD, anxiety, and related conditions.How EMDR Therapy Works
The most widely used form of EMDR follows a structured 8-phase protocol designed to reduce trauma-related distress and support nervous system regulation. The eight phases include:- History taking and treatment planning
- Preparation
- Assessment
- Desensitization
- Installation
- Body scan
- Closure
- Reevaluation
What to Expect in an EMDR Session
EMDR therapy can help reduce the intensity of traumatic memories, decrease sensitivity to past events, and allow the brain to reprocess experiences into something less painful and more adaptive. You do not need to fully articulate or consciously understand all of your triggers in order for EMDR to be effective. During reprocessing, clients may notice memories, thoughts, emotions, body sensations, or even abstract imagery such as colors or shapes. It can feel like a free-flowing stream of awareness. Importantly, the therapist does not need to know every detail of what you are experiencing internally for the process to work. Before reprocessing begins, your therapist will conduct a thorough history and develop a treatment plan. Stabilization skills—such as grounding, resourcing, and pendulation—are established first to ensure safety and emotional regulation. Each EMDR session includes a STOP signal, allowing you to pause at any time. Safety, pacing, and nervous system stability are prioritized throughout the process.Conditions EMDR Therapy Can Help Treat
EMDR therapy has been shown to be effective for:- PTSD — including survivors of abuse (physical, emotional, psychological, sexual), crime, accidents, war, and natural disasters
- Anxiety disorders
- Panic attacks and flashbacks
- Depression
- Grief and loss
- Phobias
- Sleep disturbances and trauma-related insomnia
- Eating disorders
- Chronic pain, including phantom limb pain
- Performance anxiety
- Self-esteem and negative core beliefs
- Addictions and behavioral patterns
- Recurring self-defeating patterns
When EMDR May Not Be Appropriate
EMDR therapy may not be recommended for individuals who are:- Currently experiencing active psychosis
- In acute substance use
- Severely dissociative without stabilization
- Not emotionally stable enough for trauma processing
