How EMDR-informed bilateral stimulation calms a stuck memory
Left-right cues gently tax working memory while you hold a difficult thought, softening its emotional charge. The science, made simple.
EMDR (Eye Movement Desensitisation and Reprocessing) is a leading, evidence-based therapy for trauma and PTSD. At its core is bilateral stimulation: gentle left-right cues via eye movements, taps, or tones.
The mechanism, simply
When you hold a distressing memory in mind while following a left-right cue, the cue occupies part of your working memory. With less capacity to "fuel" it, the memory's vividness and emotional charge soften, a process thought to mirror what happens during REM sleep.
What the research says
For single-incident trauma, a large share of people improve in a small number of sessions. It's recognised by the WHO and others as an effective PTSD treatment.
An important boundary
Self-guided bilateral stimulation can ease everyday stress and help you sit with a difficult thought. It is not a replacement for working through significant trauma with a trained EMDR therapist, and isn't suitable for everyone.
