Unlock Deep Healing with a Luxury Destination Therapy Intensive

If you’ve started researching trauma treatment options, you’ve likely come across both EMDR and ART, and found yourself wondering which one actually fits your situation. Both approaches use bilateral eye movements. Both help your brain reprocess distressing memories. And both aim to reduce a memory’s grip on your present without requiring you to relive it in painful detail.

So if they’re so similar, how do you know which one is right for you?

At Path to Growth Therapy, Sheila is trained in both EMDR and ART, which means you’re never locked into one method, and some clients benefit from both. This guide breaks down exactly how they compare, where each one works best, and how to make the right choice for your history and goals.

What Is EMDR Therapy?

EMDR: Eye Movement Desensitization and Reprocessing, is one of the most extensively researched trauma treatments available, formally endorsed by the World Health Organization for PTSD treatment and widely recognized across international clinical communities.

It follows a structured eight-phase protocol refined over decades of use:

Phase 1 — History taking and treatment planning. Understanding your full history, identifying target memories, and building a treatment map.

Phase 2 — Preparation and stabilization. Before any trauma processing begins, you develop the emotional regulation resources and coping tools needed to engage safely with difficult material.

Phase 3 — Assessment. Identifying a specific target memory along with the negative belief attached to it, for example, “I am powerless” or “It was my fault” — and the more accurate belief you want to move toward.

Phase 4 — Desensitization. Sets of bilateral stimulation, typically eye movements, while holding the memory in awareness, allowing the brain to begin reprocessing it.

Phase 5 — Installation. Strengthening the more accurate, adaptive belief once the emotional distress has decreased.

Phase 6 — Body scan. Checking for any remaining physical tension connected to the memory and addressing it directly.

Phase 7 — Closure. Ensuring you leave each session in a stable, grounded state — regardless of how much processing was completed.

Phase 8 — Reevaluation. Reviewing progress at the start of each subsequent session before continuing.

One thing worth knowing about EMDR: preparation takes time. Before any active trauma processing begins, a thorough assessment for dissociation is completed and emotional regulation resources are firmly established. Some clients spend several sessions in this preparation phase before processing begins — which can feel frustrating, but is a necessary foundation for safe, effective work.

If you’d like to understand what virtual EMDR therapy in Colorado looks like in practice, including how online sessions work and what each of the eight phases actually involves, our dedicated blog on the topic covers everything in detail.

What Is ART Therapy?

ART: Accelerated Resolution Therapy, is a newer approach developed by Laney Rosenzweig, built in part on EMDR’s bilateral stimulation foundation but designed to move at a significantly faster pace.

Despite its effectiveness, ART is less widely known than EMDR, partly because the developer has kept much of its specific protocol tightly guarded unless you have been formally trained in it. What is known is that it is being used increasingly across the world, including within military settings, precisely because of its speed and effectiveness with trauma.

Key features of ART include:

Faster pacing. ART sessions tend to run longer individually but are structured to move through more material within a single sitting. For single-incident trauma, meaningful relief can sometimes be achieved in as little as one session.

Active, directive approach. The therapist takes a more guiding role than in EMDR — including directing specific imagery work where you visualize replacing a distressing image with a calmer, more neutral one once its emotional charge has lifted.

Imagery replacement technique. ART’s signature technique involves consciously replacing a distressing mental image once its emotional weight has eased — a distinct step that doesn’t exist within standard EMDR protocol.

No rigid pre-treatment requirements. Unlike EMDR, ART doesn’t have strict protocols that must be met before treatment can begin, which means some clients can move into active processing more quickly.

One important consideration: ART relies heavily on working with physical sensations and imagery. If connecting to feelings in your body or engaging with metaphor-based techniques is genuinely difficult for you, EMDR’s approach may feel more accessible as a starting point.

EMDR vs ART: Key Differences Side by Side

	EMDR	ART
Session structure	Multiple sessions following 8-phase model	Fewer, longer sessions — sometimes one session per target
Therapist role	Less directive — more space for what surfaces naturally	Actively guided, including imagery replacement
Research base	Extensive — decades of studies, WHO endorsed	Growing — newer, smaller but expanding evidence base
Verbal disclosure	Minimal detail required	Even less — specifically designed to minimize re-describing trauma
Pre-treatment requirements	Thorough preparation phase required	More flexible — can begin processing sooner
Best pacing fit	Gradual, structured progress	Faster, more condensed
Imagery/body focus	Body scan included	Heavy imagery and sensation work throughout

Which Approach Works Best for Single Incident Trauma?

For a clearly defined, single traumatic event. an accident, an assault, a medical emergency, a specific loss — both approaches tend to be effective.

ART’s faster pace is often particularly appealing here, because there is usually one contained memory to target directly. The possibility of meaningful resolution within fewer sessions, sometimes just one, makes it a practical choice for people dealing with a specific, identifiable event.

That said, if metaphor-based work or connecting to physical sensations feels genuinely difficult, EMDR’s more gradual approach may be a more comfortable fit regardless of the trauma’s scope.

For people wondering whether EMDR intensives might be an option for single-incident trauma, particularly for busy professionals who need concentrated, efficient support, our blog on EMDR intensive sessions explores exactly that.

Which Approach Works Best for Complex or Layered Trauma?

For trauma built up over years, childhood experiences, long-term relational harm, repeated exposure to distressing events — EMDR’s structured, phase-based approach often provides a more manageable framework.

When there isn’t a single memory to target but rather many interconnected ones, EMDR’s systematic method of identifying feeder memories, building a treatment map, and processing targets in a considered sequence can feel more containing and less overwhelming.

That said, this isn’t a rigid rule. Many therapists trained in both approaches will adjust their recommendation or blend techniques from each, based on how you respond during early sessions. Complex trauma also frequently intersects with attachment wounds and relationship patterns that benefit from being addressed alongside trauma processing. Our blog on healing your inner child through reparenting and EMDR explores how these dimensions connect.

How to Choose: And Why You Don’t Have to Decide Alone

You are not expected to walk in already certain which approach is right for you. A qualified therapist will explain both, describe what a session of each might actually feel like, and help you choose based on your specific history, symptoms, and comfort level.

It’s also completely fine to begin with one approach, find it isn’t clicking, and switch. The ART protocol is designed to be completed within individual sessions, which makes pivoting straightforward if needed.

At Path to Growth Therapy, the first conversation together is simply about figuring out which approach makes the most sense for you — your nervous system, your history, your goals, and how each method feels once it’s been explained clearly. You can learn more about Sheila’s approach and training to see whether the fit feels right.

If your schedule is demanding and a concentrated block of intensive work suits your life better than ongoing weekly sessions, a therapy intensive may be worth exploring as a format, particularly for EMDR work, which benefits significantly from extended session time.

What Both Approaches Share

It’s easy to focus on the differences and lose sight of what makes both effective:

• Neither requires exhaustive verbal detail about your trauma
• Both use bilateral stimulation to support the brain’s natural capacity to reprocess distressing memories
• Both aim to reduce a memory’s emotional charge without erasing it
• Both can be delivered virtually as well as in person
• Both operate within a structured, time-limited framework rather than open-ended ongoing therapy
• Both are used effectively beyond trauma — including for anxiety, panic, phobias, and performance-related stress

Frequently Asked Questions

1. Is ART faster than EMDR?
Often yes — individual ART sessions tend to run longer but may require fewer total sessions, particularly for single-incident trauma. For single targets, meaningful relief can sometimes be reached in one session. EMDR typically builds more gradually across multiple appointments, with a structured preparation phase before active processing begins.

2. Can I switch from one approach to the other partway through treatment?
Yes. Because ART protocol is designed to be completed within individual sessions, switching is straightforward if needed. Many therapists trained in both — including Sheila at Path to Growth Therapy, can adjust course at any point based on how you’re responding.

3. Is EMDR more research-backed than ART?
EMDR has a considerably longer research history and broader clinical recognition, including formal WHO endorsement for PTSD treatment. ART’s evidence base is growing and it is increasingly used across military and clinical settings worldwide, but EMDR’s research base is significantly larger at this point.

4. Do both approaches work for anxiety, not just trauma?
Yes — both are used well beyond classic trauma presentations. Anxiety, panic, phobias, grief, and performance-related stress all respond well to both approaches. If anxiety is a primary concern, our blog on anxiety therapy in Colorado explores what support for anxiety actually looks like in practice.

5. What if I’ve tried EMDR before and it didn’t work?
That’s worth exploring — both in terms of why it didn’t resonate and whether ART might be a better fit for how you process. It’s also worth considering whether the format matters: EMDR intensives often reach material that weekly sessions don’t have enough time to fully process. Reach out through the contact page to discuss what a different approach might look like.

6. Can EMDR or ART be done online?
Yes — both can be delivered effectively through virtual sessions. If you’re wondering specifically what online EMDR therapy in Colorado involves and how virtual sessions work in practice, that blog walks through the process in detail.
