What are Complex Motor Stereotypies and Intense Imagery Movements?

Motor stereotypies is a clinical term that describes common things that many of us do on a daily basis, but probably don't give much thought. Do you tap your foot on the floor, shake your leg, bite your nails or twirl your hair? These are all examples of motor stereotypies.

If you’ve ever seen a child flap their hands, wiggle their fingers, or bounce in place while telling you about something exciting—they may have been engaging in something called Complex Motor Stereotypies (CMS) 

🌀 What Are Complex Motor Stereotypies (CMS)?

CMS are rhythmic, repetitive movements that some children do when they’re excited, focused, or deep in thought.They might look like:

·       Hand-flapping

·       Finger-wiggling

·       Arm-waving

·       Wiggling or hopping in place

These are not tics or seizures. They’re also not behavioral problems.CMS is a neurodevelopmental condition seen in some typically developing children and is more common in children who are neurodivergent.

The movements usually:

·       Begin in early childhood

·       Are triggered by excitement, daydreaming, or imaginative play

·       Go away if the child is distracted

·       Don’t cause harm

They’re simply how some brains express deep feeling, joy, or concentration—through movement.

🌈 What Are Intense Imagery Movements (IIM)?

IIM refers to when a child’s movements are tied to vivid mental imagery or storytelling inside their mind. These movements are an extension of the child’s inner world.

It’s like watching their imagination leak into real life—which is pretty cool, I think.

💭 Why These Movements Matter

Many kids with CMS or IIM may get odd looks or questions from peers, or even from adults who don’t understand. Or, they may just realize that they do something that their friends do not. Unfortunately, this can lead to embarrassment, shame, and an attempt to suppress their natural expressions of joy or creativity.

But when we take the time to understand these movements, we can help children feel safe, proud, and accepted. My hope is that Mira’s Magical Mind will help kids with CMS and IIM feel seen, celebrated, and empowered.

If you, or someone you know experiences CMS and/or IIM, I would love to hear about your experiences! Leave me a comment or send me and email. I'd love to connect :)

All My Best,
