Remote EMDR Technical Setup: A Step-by-Step Guide
For a remote session to be effective, the technical environment must be stable and distraction-free. This guide outlines the optimal settings for using Bilateral Focus during telehealth appointments.
1. Visual Optimization
An optimal remote EMDR setup involves separating the bilateral stimulation tool from the therapist's video feed. Using a high-resolution primary monitor for the light bar and a secondary device for video allows the client to maintain focus without technical interference.
Visual bilateral stimulation (BLS) requires smooth, rhythmic movement. If the ball "stutters," it can disrupt the processing state.- Browser Choice: Use a modern browser like Chrome, Firefox, or Safari for the best performance with Canvas API animations.
- Screen Placement: The client should be roughly 2 feet away from the screen to ensure their eyes can track the full range of motion without straining.
- Full Window Mode: Expand the browser window to fill the screen to minimize visual distractions in the background.
2. Audio Configuration
To achieve true bilateral stimulation, the audio pips must alternate between the left and right speakers or earcups.
- Wired Headphones Recommended: Bluetooth latency can occasionally cause audio to "drift" out of sync with the visual cues. Wired headphones provide the most reliable experience.
- Disable Mono Audio: Ensure that "Mono Audio" is turned OFF in the operating system's accessibility settings (found in Windows Sound Settings or macOS Accessibility).
- Test the Panning: Use the "Start" button on our homepage to confirm that you hear the tone in your left ear, then your right ear, exclusively.
3. Managing Bandwidth and Latency
When using Bilateral Focus during a Zoom or Google Meet call, bandwidth management is essential.
- Avoid Screen Sharing: The therapist should not share their screen to show the tool. Instead, the client should open the tool in their own local browser window to eliminate lag.
- Close Background Apps: Close memory-intensive applications (like Photoshop or complex spreadsheets) to ensure the browser has full access to the device's CPU.
4. Environment Setup
Ensure your lighting is even and that there are no bright lights or reflections behind the screen that could cause eye fatigue during tracking.
