Online EMDR: the full eight-phase protocol, delivered over video.
A practical, evidence-informed reference for therapists moving EMDR into telehealth — what changes, what stays the same, and what to look for in a bilateral stimulation tool.
DEFINITION
Online EMDR is Eye Movement Desensitization and Reprocessing therapy delivered by video, in which bilateral stimulation is rendered on the client's own screen through a browser-based tool controlled by the therapist. The eight-phase protocol, case conceptualisation and clinical judgment remain the same as in-person work.
What is online EMDR?
Online EMDR keeps every element of the standard EMDR protocol — history-taking, preparation, assessment, desensitisation, installation, body scan, closure and re-evaluation — and only adapts the delivery of bilateral stimulation (BLS). Instead of the therapist moving a hand or light bar in the room, the client sees a moving target on their own device and, when used, hears stereo-panned audio through their headphones.
How does bilateral stimulation work remotely?
The therapist opens a browser tab, generates a short unguessable session code, and shares it with the client. The client's screen mirrors the therapist's control panel in real time. Speed, pattern, colour, sound and volume are adjusted from the therapist's side and take effect essentially instantly on the client's display.
Why choose browser-based over app-based tools?
Browser-based delivery removes friction: no download, no account for the client, no version mismatch mid-session, and no operating-system lock-in. It also keeps a low data-collection footprint, which matters for GDPR and clinical governance.
Who is online EMDR for?
Online EMDR is used by licensed EMDR-trained therapists, psychologists and counsellors who see clients by video. Client selection follows the same standards as in-person EMDR — screening for dissociation, stability and appropriate stabilisation before reprocessing.
How does BilateralSync fit in?
BilateralSync is a browser-based bilateral stimulation platform built specifically for online EMDR. It runs alongside any video platform (Zoom, Teams, Doxy.me, Google Meet, SimplePractice) and gives the therapist synchronised visual and auditory BLS with sub-100 ms latency and no client-side account.
Frequently asked questions
Can EMDR be done online?＋
Yes. Online EMDR uses the same eight-phase protocol as in-person EMDR. Bilateral stimulation is delivered on the client's own screen through a browser tab that runs alongside the video call. Peer-reviewed studies show outcomes broadly comparable to in-person EMDR when protocol fidelity is preserved.
Is online EMDR as effective as in-person EMDR?＋
Published trials and clinical case series report similar reductions in PTSD symptoms for video-delivered EMDR compared with in-room work. Effectiveness depends on stable video, informed consent, careful client selection and preserving the full eight-phase protocol.
What equipment do therapists need for online EMDR?＋
A modern browser, a stable internet connection, a video platform such as Zoom, Teams or Doxy.me, and a browser-based bilateral stimulation tool the client can see on their own screen. Headphones on the client side are recommended when using auditory BLS.
What equipment do clients need?＋
A laptop, tablet or desktop with a modern browser and a stable connection. Clients do not need to install anything to use BilateralSync — they open a session link and see the bilateral stimulation directly in their browser.
How is bilateral stimulation delivered remotely?＋
The therapist controls a target that renders on the client's screen in real time, with synchronized stereo audio for auditory BLS. Sub-100 ms sync keeps speed and pattern changes essentially instantaneous from the therapist's perspective.
Is online EMDR appropriate for every client?＋
No. Client selection follows the same clinical judgment as in-person EMDR — screening for dissociative features, current safety, and the ability to use grounding remotely. Established guidance recommends adapting stabilization work before reprocessing when appropriate.
