What Is EMDR Therapy?
EMDR stands for Eye Movement Desensitization and Reprocessing. It’s a structured psychotherapy that helps people process traumatic memories and reduce their emotional charge. Unlike talk therapy alone, EMDR uses bilateral stimulation, usually eye movements, to help your brain reprocess distressing experiences so they don’t control your present emotions or reactions.
This therapy isn’t just for PTSD. I’ve seen it work wonders for people dealing with anxiety, phobias, grief, and even chronic pain. And yes, EMDR can be done safely online with trained therapists, which is great if you’re in Markham, Durham Region, or anywhere in Ontario.
Here’s a solid resource if you want to check the official stance and research on EMDR: EMDR International Association. It’s smart to know what the experts say before committing to anything significant.
You might wonder why eye movements or other types of bilateral stimulation make a difference. The truth is, the exact mechanism isn’t fully understood, but many theories suggest it helps the brain rewire how traumatic memories are stored. This means the emotional charge attached to those memories can fade, making them easier to face. And that is huge.
Phase 1: History and Treatment Planning
This phase isn’t just casual chat. Your therapist will take a detailed history to identify traumatic events, current stressors, and your mental health status. They’ll also assess your readiness for EMDR because this therapy isn’t a fit for everyone right off the bat.
For example, if someone is in a highly unstable life situation or has unmanaged substance use issues, EMDR right away might do more harm than good. The therapist’s job here is to ensure safety and tailor the treatment plan accordingly. I’ve had clients rush into EMDR without this groundwork, and it backfired badly. They felt overwhelmed and sometimes retraumatized.
Don’t skip this part or rush through it. Think of it as laying the foundation. You wouldn’t build a house without checking the ground first, right? The same goes for therapy. This phase includes discussing your goals, clarifying expectations, and sometimes addressing immediate safety concerns like suicidal thoughts or self-harm behaviors.
Your therapist should also be transparent about what EMDR can and can’t do. No one should promise instant miracles or say EMDR will erase your past. Setting realistic expectations early on is one of the best things you can do for your healing journey.
Phase 2: Preparation
Think of this as building your emotional toolbox. Your therapist will teach you coping skills to handle distress that might come up during or between sessions. Grounding techniques, breathing exercises, and ways to self-soothe are common here.
This part matters a lot. If you don’t feel safe or capable of managing your emotional responses, the trauma can feel worse after an EMDR session. Some therapists underestimate the preparation phase, but in my experience, it can be the difference between progress and setbacks. For example, I once worked with a client who didn’t get enough preparation and ended up having panic attacks after sessions. We had to backtrack and spend extra time reinforcing those skills before continuing.
Preparation also includes explaining how EMDR works, so there are no surprises. Clients often say this reassurance lowers their anxiety about the process. You might learn about the typical sensations and emotions that come up, which can feel strange if you’re not expecting them.
Another important part of preparation is establishing a strong therapeutic relationship. You need to feel comfortable and trust your therapist. If you don’t click with someone, it will be harder to engage fully. Don’t settle for a therapist who rushes or seems distracted during this phase. Your safety and trust are the pillars of effective EMDR.
Phase 3: Assessment
Here, you and your therapist identify specific target memories and the negative beliefs, emotions, and body sensations linked to them. For instance, a memory might come with the belief “I am powerless” or a feeling of tightness in the chest.
The goal is to clearly define what you want to work on, so treatment stays focused. This phase can feel intense emotionally because you’re revisiting painful things, but it’s a necessary step before reprocessing. If you try to skip this and jump straight to desensitization, it often doesn’t stick, and you might feel worse afterward.
Don’t expect immediate relief here. It’s normal to feel vulnerable and raw after diving into your trauma memories. Some clients get discouraged because they expected to feel better right away. This phase is about gathering all the pieces so the brain can do its work in the next phases.
The therapist will help you rate the intensity of the memory using scales like SUDS (Subjective Units of Distress Scale), which goes from 0 to 10. This helps track progress later. For example, a traumatic memory might start at a 9 and, after sessions, drop to a 2 or 1, showing real improvement.
Phase 4: Desensitization
This is the core EMDR work. Your therapist will guide you through sets of bilateral stimulation, usually rapid eye movements, taps, or sounds, while you focus on the traumatic memory.
The bilateral stimulation helps your brain process the memory differently. You might notice shifts in how you feel or think about the event across sets. Sometimes the memory becomes less vivid or upsetting. Other times, new insights pop up that change your perspective.
It’s not always smooth sailing. Some clients feel overwhelmed or disconnected during this phase, which is why solid preparation and therapeutic support matter so much. For instance, I’ve seen clients who dissociate, meaning they mentally check out or feel numb, which can stall progress. Therapists trained in EMDR usually have strategies to gently bring clients back or slow down the pace.
EMDR isn’t about forcing you to relive trauma in detail or talk it through endlessly. You don’t have to share everything during desensitization if it feels too hard. Your therapist might ask you to hold the memory in mind just enough to work through the distress.
Sometimes, memories pop up unexpectedly between sessions. This is common and doesn’t mean EMDR failed. It means your brain is still sorting stuff out. Having your grounding skills ready will help you through those moments.
Phase 5: Installation
Once the negative emotions around a memory start to fade, this phase focuses on strengthening a positive belief about yourself. That belief might be something like “I am safe now” or “I am in control.”
The therapist helps you focus on that positive belief while continuing bilateral stimulation. This helps “install” the new way of thinking and feeling in your brain. Think of it like updating the software on your emotional operating system.
The tricky part is picking the right positive belief. I’ve had clients struggle here because their chosen belief was too far from what they truly felt. For example, someone might say “I am strong,” but deep down doesn’t believe it yet, which can create resistance.
Your therapist should guide you toward realistic and believable affirmations. Sometimes it’s better to start with something smaller and more believable like “I can get through this,” then work toward bigger beliefs over time. The installation phase is where you cement the changes, so don’t rush it.
Phase 6: Body Scan
Trauma isn’t just mental; it’s physical too. This phase has you check for any residual tension or discomfort in your body when thinking about the memory and positive belief.

If there’s still a physical reaction, the therapist may guide you through more bilateral stimulation targeting those sensations. This phase ensures your body has fully processed the trauma along with your mind. I’ve seen people feel better emotionally after EMDR but still carry physical symptoms like tightness in the shoulders or stomach aches, which can keep triggering stress.
Skipping the body scan is a common mistake I see. People come out of EMDR sessions feeling emotionally better but still have subtle physical distress that can cause future problems. Addressing the body’s response is essential for deeper healing and preventing symptoms from resurfacing later.
The body scan can reveal surprising things. Sometimes, you might discover that a certain memory triggers not just sadness or fear but physical sensations like nausea or dizziness. Recognizing and working through those is key.
Phase 7: Closure
Each session ends with closure, making sure you leave feeling safe and grounded. Your therapist may review coping strategies and check your emotional state.
If the memory isn’t fully resolved, the closure phase ensures you won’t be left overwhelmed between sessions. This is why rushing EMDR or doing too much in one session can backfire. I’ve had clients leave sessions feeling worse because the therapist didn’t spend enough time on closure.
Closure might include relaxation techniques, mindfulness exercises, or chatting through how you’re feeling before you leave. Some therapists provide a “safe place” visualization to help you emotionally settle.
It’s critical that you have a plan for self-care after sessions. EMDR can bring up intense feelings that linger. Make sure your therapist discusses what to do if you get triggered when you’re on your own. This could mean having a trusted friend to call, journaling, or practicing grounding exercises.
Phase 8: Reevaluation
At the start of your next session, your therapist will check how you’ve been since the last meeting. This includes assessing any changes in your symptoms, beliefs, and physical sensations around the target memories.
This phase helps decide what to work on next or if more processing is needed. It’s also a checkpoint for seeing overall progress. Sometimes, even when a memory seems resolved, unexpected feelings or memories can emerge, and reevaluation gives space to address those.
Reevaluation also includes re-rating distress levels and positive beliefs using the scales introduced earlier. This way, you and your therapist can objectively see improvements or areas needing more work. Tracking this progress keeps you motivated, even when the path feels slow.
Common Mistakes to Avoid in EMDR
- Rushing through preparation or skipping it altogether. This is huge. Don’t shortchange your emotional toolbox.
- Choosing a therapist without proper EMDR training or certification. EMDR requires specialized skills that not everyone has.
- Expecting immediate “cure” after a few sessions. EMDR is powerful but often takes time. Healing isn’t a race.
- Not communicating openly about discomfort during sessions. Your therapist can’t help if they don’t know what you’re experiencing.
- Trying to self-administer EMDR techniques without professional guidance. This can be dangerous and counterproductive.
Trust me. Trying to shortcut any phase can create setbacks or retraumatize you. It’s tempting to want fast answers, but this process requires patience and collaboration. Healing is a journey, not a sprint.
Red Flags and Warning Signs
Not all therapists who offer EMDR do it well. Watch out for these signs:
- They push you to disclose trauma too quickly or seem uninterested in your emotional safety. That’s a big no.
- They don’t explain the process or risks clearly. You deserve full transparency.
- They skip preparation or closure phases. Missing these is a red flag.
- They ignore your feedback or discomfort during sessions. Your experience matters.
- They don’t have recognized EMDR certification or supervision. This is non-negotiable.
If you notice these, don’t hesitate to pause therapy and look for someone who prioritizes your well-being. You deserve that. I’ve seen clients stay too long with unqualified therapists and end up feeling worse. You’re worth better care.
How to Choose an EMDR Therapist
Picking the right therapist matters more than you might think. Here’s what I suggest:
- Verify their credentials and EMDR training. EMDRIA-certified therapists are a solid bet. You can often find directories online to confirm this.
- Ask about their experience with your specific concerns, whether it’s trauma, anxiety, or relationship issues. Experience counts, especially with complex cases.
- Make sure you feel heard and respected during your initial consultation. Rapport is crucial. If you don’t feel safe or comfortable, keep looking.
- Check if they offer flexible formats, like online therapy, especially if you’re in Ontario but not close to Markham or Durham Region. Accessibility matters a lot.
- Ask about their approach to preparation and aftercare. These are the phases that often get overlooked.

Quick Checklist Before Starting EMDR Therapy
- Have you shared a full history with your therapist, including current stresses? Be as honest as possible.

- Are your therapist’s credentials and approach clear to you? Don’t hesitate to ask for proof or explanation.
