What Is EMDR Therapy and How Does It Work
Wondering what is EMDR therapy and how it helps trauma recovery? Explore how memory reprocessing works and what to expect from care in Australia.
What is EMDR therapy? Eye Movement Desensitisation and Reprocessing is an evidence-based therapy that helps the brain reprocess distressing memories. Developed by Dr Francine Shapiro in 1987, it uses rhythmic sensory inputs to reduce the emotional distress tied to past events. You can work through difficult material without speaking about every detail out loud.
Key Takeaways
EMDR targets memories stored in raw, reactive states and helps file them into long-term memory.
Sessions use bilateral stimulation like side-to-side eye movements, auditory tones, or hand taps.
Dual attention taxes your working memory, making traumatic memories less vivid and less distressing.
The standard model follows eight distinct phases, starting with preparation and grounding skills.
Australian clients can access session rebates through Medicare under a GP Mental Health Treatment Plan.
The Core Science: What Is EMDR Therapy?
Traumatic memories often sit in the nervous system differently from everyday memories. When an event overwhelms your nervous system, the brain's natural sorting mechanism stalls. Images, sounds, and physical reactions remain stuck in their original state.
This therapy relies on the Adaptive Information Processing model. The model states that the brain has an innate system to process disturbing events toward psychological resolution. When a memory stays stuck, that system cannot do its job.
Through our work providing counselling for adults, we see how unprocessed memories trigger fight, flight, or freeze reactions in daily life. EMDR unfreezes those memory networks. Once processed, the memory shifts into standard autobiographical memory. You remember the facts of what happened, but your body no longer reacts to the memory as an active emergency.
How Bilateral Stimulation Changes the Brain
The main tool used in sessions is bilateral stimulation. This is an alternating left-to-right sensory cue across the body. Clinicians usually ask you to follow a moving light bar, track fingers, listen to alternating tones in headphones, or hold small tactile units that vibrate softly in each palm.
This sensory input acts as a dual attention stimulus. You keep one foot in the present moment while holding a part of the old memory in mind. Research on working memory taxation in Behaviour Research and Therapy shows that your working memory has limited capacity. Because the sensory task takes up processing bandwidth, the distressing image becomes less vivid and loses its emotional charge.
Brain scans also show measurable changes during this work:
Amygdala hyperactivation drops, reducing fight-or-flight distress.
Prefrontal cortex down-regulation eases, which restores clear reasoning.
Hippocampal memory consolidation activates, which files the event into the past.
The 8-Phase Protocol: Your Journey Through Care
EMDR follows an eight-phase protocol. This sequence ensures you have practical grounding tools before you begin reprocessing difficult memories.
Phases 1 and 2: History Taking and Preparation
First, the clinician gathers background details, checks your stability, and maps out target memories. You do not reprocess memories right away. Instead, you learn nervous system regulation tools, including safe place visualization and mental containment techniques, to manage distress between sessions.
Phase 3: Assessment
The clinician helps you select an exact image representing the target memory. You identify the negative belief attached to it, like "I am in danger," and select an adaptive positive belief, like "I am safe now."
Progress is tracked with two standard clinical metrics:
Subjective Units of Disturbance, which rates emotional pain from 0 (neutral) to 10 (highest distress).
Validity of Cognition, which measures how true the positive statement feels from 1 (completely false) to 7 (completely true).
Phases 4 to 6: Desensitisation, Installation, and the Body Scan
During desensitisation, you focus on the memory while following bilateral stimulation sets lasting 20 to 30 seconds. Between sets, the clinician pauses and asks what you notice. You describe whatever thought, image, or physical sensation comes up.
Once your distress rating drops to 0 or 1, installation begins. Bilateral stimulation strengthens your chosen positive belief until it rates 6 or 7 on the validity scale. You then do a full body scan from head to toe to notice and process any tightness or tension held in your muscles.
Phases 7 and 8: Closure and Re-evaluation
Every reprocessing session ends with grounding exercises so you leave the room calm and settled. The next session opens with a re-evaluation to verify that previous targets remain calm and resolved.
How EMDR Differs from Traditional Talk Therapy
Conventional counselling typically uses dialogue to examine current thoughts, communication habits, and behavioral patterns. These methods often assign weekly homework, like writing in thought logs or doing exposure exercises.
EMDR works on the underlying memory networks instead of conscious conversation. You do not have to describe what happened out loud or explain private details to your therapist. Most of the processing happens internally while you follow the sensory cues.
Reviews from the American Psychological Association confirm that this structured reprocessing produces reliable clinical symptom reduction across trauma-related conditions.
Conditions Supported Beyond PTSD
While developed for post-traumatic stress, clinical research shows EMDR helps with several other mental health concerns:
Generalised anxiety and panic disorder
Specific phobias and social anxiety
Complicated grief and bereavement
Unhelpful self-beliefs formed during childhood
Chronic pain and somatic tension
Single-incident trauma, like a car crash, is often studied in short protocols of 3 to 6 sessions. Complex developmental trauma or prolonged childhood neglect requires more preparation and longer treatment to establish safety.
Evidence and Clinical Standards in Australia
Major international health organisations endorse EMDR as an effective trauma intervention. The World Health Organization recommends it for treating post-traumatic stress in adults and children. In the United Kingdom, the National Institute for Health and Care Excellence lists it as an evidence-based trauma treatment.
In Australia, training standards are governed by the EMDR Association of Australia. Clinicians must hold a primary mental health qualification and complete accredited training and supervision hours to practice.
You can access rebates for therapy in Australia through the Medicare Better Access initiative when your care is provided by an eligible registered mental health clinician. Talk to your GP to see if you qualify for a Mental Health Treatment Plan, which covers up to 10 subsidised sessions per calendar year through Services Australia.
What to Expect After an Active Session
Your brain continues sorting and integrating information for several days after an active reprocessing session. This is an expected part of memory consolidation.
Common experiences after a session include:
Physical tiredness or a desire for extra sleep
Vivid or unusual dreams as your brain processes old material
Light emotional shifts or unexpected memories surfacing
A gradual feeling of physical lightness and calm
Drinking water, taking gentle walks, and resting help your body settle. These sensations usually fade within two to three days as your nervous system rebalances.
Frequently asked questions
Do I have to describe my trauma in full detail?
No. You do not need to give a graphic description out loud. Reprocessing happens internally while you track the bilateral cues. You only need to share brief words about what you notice during pauses.
How many sessions will I need?
Session counts vary based on your history. Single-incident events are often evaluated across 3 to 6 processing sessions. Complex or long-term trauma requires more sessions to build trust, stability, and emotional regulation.
Can EMDR be delivered via telehealth?
Yes. Telehealth EMDR uses secure video software with visual indicators or alternating audio tones. Your therapist will evaluate whether an online setting is safe and suitable for your specific needs before starting.
