Can EMDR Cause Temporary Trembling?

Can EMDR Cause Temporary Trembling?

Short Answer: Some people may notice temporary trembling, shakiness, or a brief shiver during Eye Movement Desensitization and Reprocessing (EMDR), particularly while focusing on emotionally activating material. Stress and emotional arousal can sometimes produce muscle tension or trembling, and EMDR specifically includes noticing body sensations that arise during processing. However, trembling is not an established standard EMDR side effect, and many people will never experience it. If trembling comes up, you can notice it without assuming that it has a special meaning or that it shows how well the session is working.

Key Takeaways

• Temporary trembling or shakiness may sometimes become noticeable during emotionally activating EMDR.
• Stress and emotional arousal can produce physical responses such as muscle tension or trembling.
• EMDR specifically includes body sensations among the things you may notice during processing.
• Trembling is not something everyone should expect during EMDR.
• A stronger physical response does not mean the session is working better.
• You do not need to deliberately stop or encourage a mild temporary tremble.
• Cold temperature, caffeine, fatigue, muscle tension, and other everyday factors can also contribute to shakiness.
• If trembling is distracting, you can pause, reconnect with the present, and continue when the pace feels workable.

What Does Temporary Trembling Feel Like?

People may use several words to describe a similar sensation:

• Trembling
• Shakiness
• A slight quiver
• A brief shudder
• Hands that feel shaky
• Legs that briefly tremble
• Muscles that feel unsteady
• A short wave of shaking

The sensation may be very subtle.

For example, you might notice:

“My hands are trembling a little.”

or:

“My legs feel slightly shaky.”

It may last for only a few moments or change as the session continues.

Why Might Trembling Come Up During EMDR?

EMDR involves focusing on emotionally meaningful material while noticing what happens from one set of bilateral stimulation to the next.

What comes up can include:

• Thoughts
• Images
• Memories
• Emotions
• Beliefs
• Physical sensations

EMDR guidance specifically asks people to notice what happens in their thoughts, feelings, and body sensations without immediately trying to change it.

Trembling can simply be one physical sensation that becomes noticeable during that process.

Can Emotional Activation Cause Shaking?

Yes.

Stress activates automatic body systems that help prepare you to respond to what is happening. Physical stress responses can include muscle tension, a faster heartbeat, sweating, changes in breathing, and shaking or trembling.

That helps explain why trembling may occasionally appear while someone is focusing on emotionally activating material.

It does not mean that EMDR itself normally causes shaking.

It means that emotional activation can sometimes have a physical component.

Is Trembling a Standard EMDR Side Effect?

No.

There is not good evidence establishing temporary trembling as a standard EMDR side effect or showing that most people experience it.

A more accurate description is:

Some people may notice trembling as one possible body response during emotional activation.

Another person may notice:

• Muscle tension
• A faster heartbeat
• Changes in breathing
• Stomach sensations
• Warmth or chills
• No obvious physical response

There is no required EMDR reaction.

Does Trembling Mean You Are Afraid?

Not necessarily.

Trembling can accompany fear or anxiety, but those are not the only situations in which people can feel shaky.

Stress, anticipation, excitement, fatigue, cold temperatures, caffeine, or sustained muscle tension can also contribute.

If fear is clearly present, you can notice it.

If all you know is:

“My hands are shaking slightly,”

you do not have to immediately decide what emotion caused it.

Does Trembling Mean the Memory Is Especially Important?

No.

One target may be accompanied by noticeable trembling.

Another may bring up strong emotion without any shakiness.

A third may mainly produce thoughts, images, or changes in perspective.

The strength of a physical sensation does not tell you how important a target is.

Does Trembling Mean EMDR Is Working?

No.

Trembling is not a measure of EMDR effectiveness.

You do not need to:

• Shake
• Cry
• Sweat
• Feel chills
• Experience tingling
• Have a faster heartbeat
• Notice any other strong physical sensation

for EMDR processing to occur.

EMDR involves noticing changes in thoughts, feelings, images, beliefs, and body sensations. No single physical response functions as a progress test.

Should You Try to Stop the Trembling?

Usually, you do not need to fight a mild, temporary tremble.

You can simply notice it:

“I notice some shaking in my hands.”

Then see what comes up next.

At the same time, you do not need to encourage the trembling or assume that allowing more shaking will improve the session.

The goal is neither to suppress nor produce a body reaction.

It is to notice what is actually happening.

Can You Pause if You Feel Shaky?

Yes.

If trembling becomes distracting, you can pause.

You might:

• Feel your feet on the floor
• Notice the chair supporting you
• Look around the room
• Move your hands or legs
• Let your shoulders soften
• Take a sip of water
• Give yourself a moment before continuing

EMDR processing already includes pauses between sets, and noticing what is happening in the present is consistent with the process.

Can Trembling Change During the Session?

Yes.

You might notice:

“My hands were shaking, but now they are still.”

Or:

“The trembling is less noticeable than it was a minute ago.”

The sensation might also move from one part of the body to another or be replaced by a different sensation.

You do not need to make any of these changes happen.

Simply notice what changes naturally.

Could You Just Be Cold?

Yes.

A brief shiver or trembling sensation may have nothing to do with emotional processing.

Possible contributors include:

• A cold room
• Air conditioning
• A fan
• Lightweight clothing
• Sitting still for a long time

If you are physically cold, make an ordinary comfort adjustment.

Put on another layer, use a blanket, or adjust the room temperature.

There is no reason to remain uncomfortable because the sensation happened during EMDR.

Could Caffeine or Fatigue Contribute?

Yes.

Shakiness can have many everyday causes.

Caffeine may make some people feel more jittery, while fatigue or lack of sleep can make certain types of trembling more noticeable. Stress can also worsen existing tremor.

That means the timing of trembling during EMDR does not prove that EMDR caused it.

Several factors may be contributing at the same time.

Could You Simply Notice an Existing Tremble More?

Yes.

EMDR repeatedly directs attention toward internal experiences.

Sometimes that means you become aware of something that was already happening.

For example, you may suddenly notice that your fingers are slightly shaky even though you were not paying attention to them before.

In that case, EMDR may have increased your awareness of the sensation rather than created it.

What About Trembling During a Strong Emotional Moment?

A stronger emotional moment may sometimes coincide with more noticeable physical activation.

If that happens, you can report exactly what you notice:

“That brought up sadness, and my hands started trembling.”

There is no need to turn that observation into a larger conclusion.

A strong response does not mean something went wrong, and it does not automatically mean that this was the most important part of the session.

“Strong” simply describes the intensity of the experience at that moment.

What If You Do Not Tremble at All?

That is completely possible.

Many people may never experience trembling during EMDR.

You might instead notice:

• A thought shifting
• A memory becoming less vivid
• A change in emotion
• A different physical sensation
• A new association
• Very little physically

There is no physical reaction you have to produce for EMDR to be effective.

What About the EMDR Body Scan?

The body scan is one of the standard phases of EMDR.

After processing and strengthening a positive belief, the target and positive belief are held in mind while you mentally scan your body for any remaining disturbance or unusual sensations.

If trembling is still noticeable, you can simply report it.

For example:

“There is still a slight tremble in my hands.”

The purpose is to notice what is actually there—not to search for shaking or another physical response.

Can Trembling Continue After EMDR?

You may occasionally notice that you still feel somewhat shaky for a short time after an emotionally activating session.

But you do not need to automatically label every later tremble as continued EMDR processing.

Temperature, caffeine, fatigue, stress, hunger, activity, and many other ordinary factors can influence how steady your body feels.

If the sensation passes, there is generally no need to keep checking for it.

Should You Track Trembling Between Sessions?

Usually, no detailed tracking is needed.

If something meaningful stands out, you might make a simple note such as:

“Hands trembled briefly when that memory came up.”

or:

“Same memory came up later without the shakiness.”

That preserves useful information without turning the rest of your day into constant body monitoring.

Is Temporary Trembling Different From an Ongoing Tremor?

Yes.

A brief shaky feeling during emotional activation is different from a recurring or persistent involuntary tremor.

A medical tremor is an involuntary rhythmic movement that can have many possible causes. If trembling regularly happens outside EMDR, gets progressively more noticeable, or interferes with ordinary activities, it makes sense to consider it separately rather than assuming EMDR explains it.

That distinction does not make temporary session-related shakiness unusual. It simply avoids attributing every tremor to EMDR.

What About Therapist-Guided Online EMDR?

The same principles apply during therapist-guided EMDR by video.

If you notice trembling, you can simply tell the therapist:

“My hands feel shaky.”

The therapist can include that observation with the thoughts, emotions, images, and other body sensations coming up during processing.

You can also pause, shift position, or reconnect with your surroundings if useful.

What About Self-Guided EMDR?

The same practical approach applies during Virtual EMDR, the structured self-guided online program.

With Virtual EMDR, you manage your own pacing and pauses and can select or adjust the available visual or audio bilateral stimulation settings.

If trembling becomes noticeable:

• Notice it without trying to interpret it.
• Check whether you are cold or physically uncomfortable.
• Pause if the shaking becomes distracting.
• Reorient to the present if useful.
• Continue when the pace feels workable.

You do not need to change the bilateral stimulation simply because you noticed a brief tremble.

Conclusion

Temporary trembling can sometimes become noticeable during EMDR, particularly while emotionally activating material is being processed.

That is plausible because stress and emotional arousal can sometimes produce shaking or muscle tension, and EMDR specifically includes awareness of body sensations during processing.

But trembling is not a required EMDR response.

It does not prove that a memory is especially important.

It does not show that processing is working better.

And other ordinary factors may contribute to shakiness.

If temporary trembling comes up during EMDR, notice it without turning it into a test of the session, pause if useful, and allow the sensation to change naturally rather than feeling that you have to explain or control it.
