EMDR, or Eye Movement Desensitization and Reprocessing, tends to raise eyebrows when people first hear about it. Moving your eyes back and forth while thinking about trauma sounds, on the surface, more like something from a late-night infomercial than a rigorously studied psychotherapy. But the evidence base for EMDR is extensive, and it has been recognized as an effective treatment for PTSD by the World Health Organization, the American Psychological Association, and numerous national health bodies worldwide.
Here is what it actually involves and how it differs from more traditional talk therapy approaches.
The Core Difference: Processing vs. Talking
The central distinction between EMDR and most talk therapies lies in what is being targeted. Talk therapies like cognitive-behavioural therapy (CBT) work largely through conscious cognitive processing: identifying distorted beliefs, examining evidence, building coping skills, and developing new ways of understanding past events.
EMDR operates through a different mechanism. It targets traumatic memories at the level of encoding and storage in the nervous system, working with the hypothesis that traumatic memories are stored in a dysfunctional way, meaning they remain fragmented, emotionally charged, and disconnected from the broader memory network in a way that keeps them feeling current and threatening. EMDR appears to facilitate the reprocessing of those memories so that they can be integrated into the memory network in a more adaptive way.
The result, when the protocol works, is not that the memory disappears. It is that it loses its charge. Clients often describe the shift as: 'I know it happened, but it does not feel like it is still happening.'
What Does a Session Actually Look Like?
EMDR involves eight phases, from history-taking and preparation through to reevaluation of treatment outcomes. The core processing phases involve the client holding a target memory in mind while also engaging in bilateral stimulation, the most common form being guided eye movements following the therapist's hand, though auditory tones or tactile taps on alternating sides of the body are also used.
The bilateral stimulation is thought to work by engaging both hemispheres of the brain simultaneously in a way that reduces the emotional intensity of the memory while it is being processed, possibly mimicking some aspects of REM sleep, during which the brain also consolidates and integrates emotional memories (Stickgold, 2002). The research on the precise mechanism is ongoing, but the clinical outcomes are well-documented.
Notably, EMDR does not require extensive verbal narration of trauma. Clients are not asked to describe their trauma in detail repeatedly, which is one meaningful difference from exposure-based approaches and one reason some clients find it more tolerable.
What the Research Shows
EMDR has a particularly robust evidence base for PTSD. A meta-analysis by Chen et al. (2015) found that EMDR produced significant reductions in PTSD symptoms compared to control conditions, with effect sizes comparable to trauma-focused CBT. The treatment is typically shorter than CBT, with many clients showing significant improvement within 8 to 12 sessions.
Beyond PTSD, EMDR has been studied for depression, anxiety, complicated grief, performance anxiety, and phobias. Research specifically examining EMDR for chronic pain is growing, with preliminary evidence suggesting that it can reduce pain intensity for pain conditions with a significant neurological or psychological sensitization component (de Roos et al., 2010).
When Is EMDR a Better Fit Than Talk Therapy?
EMDR tends to be particularly useful when there is a clear traumatic memory or cluster of memories driving present-day symptoms. This includes single-event trauma, complex trauma from childhood, and situations where a person understands cognitively that a past event should not still be affecting them, but it still clearly is.
For sexual pain specifically, trauma history, including sexual trauma, is a meaningful contributor to both the development and the maintenance of certain pelvic pain conditions. Where trauma is identified as a significant factor, EMDR may be a more direct route to processing that material than traditional talk therapy.
It is also worth noting that EMDR and talk therapy are not mutually exclusive. Many clinicians integrate EMDR techniques within a broader therapeutic relationship that includes supportive, cognitive, and attachment-based work.
Finding an EMDR Therapist
In BC, you can find EMDR-trained therapists through the EMDR Canada directory at emdrcanada.org, which allows you to search by location and specialty. Looking for therapists who are trained or accredited through EMDR Canada or EMDR International Association (EMDRIA) ensures a baseline of training quality.
If you are considering EMDR therapy in Victoria, BC or virtually across BC and Alberta, you can learn more about how I use EMDR and Accelerated Resolution Therapy as part of trauma-focused treatment. For those navigating pelvic or sexual pain with a trauma history, EMDR is often a central part of the work rather than an adjunct. Get in touch if you would like to talk through whether this approach might be right for you.
