EMDR Therapy: Understanding What It Involves
Eye Movement Desensitisation and Reprocessing (EMDR) therapy is a structured psychotherapy developed by Francine Shapiro in the late 1980s, initially for the treatment of PTSD. It is now one of the most extensively researched trauma therapies in existence, with recommendations from NICE, the World Health Organisation, and the American Psychological Association. What makes it distinctive — and what makes many people curious about it — is its use of bilateral stimulation, most commonly guided eye movements, while the client attends to distressing memories.
The theoretical model underlying EMDR is the Adaptive Information Processing model. This proposes that psychological difficulties arise from memories that have been stored in an unprocessed, maladaptive form — not fully integrated into the person's broader adaptive memory network. These unprocessed memories continue to be activated in something close to their original form when triggered by current stimuli, producing emotional, cognitive, and physiological responses that belong to the past but feel present. EMDR aims to facilitate the processing of these memories so that they are stored in a more adaptive, integrated way and no longer intrude on present experience in their original form.
The EMDR protocol has eight phases. The earlier phases involve history-taking, identifying target memories and current triggers, and preparation — including stabilisation work for clients who need it before active processing begins. The active processing phases involve the client holding a target memory in mind while following the therapist's bilateral stimulation (typically following the therapist's fingers with the eyes), and reporting what arises. Processing typically continues until the memory loses its disturbance and a more adaptive perspective can be installed.
The question of why bilateral stimulation works is not fully settled. Several hypotheses are current: the working memory hypothesis (holding the target memory in mind while performing a working-memory task depletes the memory's vividness); the orienting response hypothesis (bilateral stimulation activates the orienting response, which is incompatible with the threat response); and the REM sleep analogy (bilateral stimulation may activate a mechanism similar to the memory processing that occurs during REM sleep). The research evidence for EMDR's effectiveness does not depend on settling the mechanism question.
EMDR is not only for PTSD. It is used for complex trauma, phobias, grief, performance anxiety, and depression where trauma or difficult memories are a maintaining factor. Maia, the AI companion in Asclepiad, offers space to understand what EMDR therapy involves and whether it might suit your situation.
Frequently Asked Questions
Is Asclepiad designed for EMDR?
Asclepiad is suited to exploring what EMDR involves and whether it might be relevant to your situation. For accredited EMDR therapists, the EMDR Association UK and Ireland (emdrassociation.org.uk) maintains a register of accredited practitioners with training levels and specialisms listed.
What if I am in crisis?
Asclepiad is not a crisis service. If you are in immediate distress or at risk to yourself or someone else, please contact the Samaritans on 116 123 (free, 24/7, UK and Ireland) or your local emergency services. Maia will also surface local helplines if something needs more than reflection.
Is it free?
Yes — begin with a 7-day free trial, no personal details required. Use AsclepiCoins after that: pay for what you use, nothing expires.
