Browser-Based BLS for EMDR Sessions

This free BLS tool is designed for trained EMDR therapists who need a lightweight way to run visual or auditory bilateral stimulation during in-person or telehealth sessions. Use it alongside your EMDR protocol, consultation, consent process, and clinical judgment.

How the EMDR workflow connects

The free BLS tool is most useful when it sits inside the target, ratings, closure, and note workflow.

  1. 1
    Target

    Past, present, future sequence

  2. 2
    BLS set

    Visual or auditory stimulation

  3. 3
    SUD/VOC

    Ratings between sets

  4. 4
    Closure

    Completion or containment

  5. 5
    Note

    Clinician-reviewed documentation

Use this as a quick orientation: BLS is the in-session action, but SUD/VOC tracking and documentation are the workflow moat.

How to Use the BLS Tool

  1. 1. Choose the stimulation mode - Select visual, audio, haptic-supported, or combined BLS based on the session setup.
  2. 2. Set speed and atmosphere - Adjust pacing and the visual environment before starting a set.
  3. 3. Track session ratings - Capture SUD and VOC ratings when clinically appropriate.
  4. 4. Save repeatable settings - Store preferred BLS configurations as templates for future sessions.
  5. 5. Export what you need - Copy or export de-identified session information for your documentation workflow.

Frequently Asked Questions

What is bilateral stimulation in EMDR? +

Bilateral stimulation (BLS) is a core component of EMDR therapy where alternating sensory input is used to support memory processing. Common forms include visual tracking, alternating audio, and tactile or haptic cues.

Is this EMDR tool free? +

Yes. The EMDR bilateral stimulation tool is free to use in the browser, and the soft email prompt can be skipped.

Can I use this for telehealth EMDR sessions? +

Yes. Therapists can open the tool fullscreen and share their screen through a telehealth platform. Use appropriate EMDR training, consent, safety planning, and clinical judgment.

What are SUD and VOC in EMDR? +

SUD, often written SUDS, is a 0 to 10 distress rating. VOC is a 1 to 7 rating of how true a positive cognition feels. EMDR clinicians often track both during target setup, processing, installation, closure, and reevaluation.

Does CoralEHR store client session data from this page? +

No. The public BLS tool runs in the browser. Avoid entering names, PHI, or identifying clinical details into free public tools.

What keyboard shortcuts are available? +

Spacebar starts and stops BLS. Arrow keys adjust speed. Number keys switch atmosphere presets when the tool has focus.
