7 Everyday Signs Your Child’s Primitive Reflexes Aren’t Integrated

In this episode, we explore how totrack progress beyond reflex testing by looking atfunctional, everyday signs of improvement. Reflex tests are important, but they don’t always tell the whole story. Sometimes a child may have several retained reflexes, but those reflexes don’t significantly interfere with their day-to-day life!

If you’ve ever wondered whether your reflex integration work istruly helping, this episode will help you connect the dots betweenreflexes,functional outcomes, andreal-life independence.

This episode will help you shift your focus fromtesting and exercises alone to looking atreal-life skills—because progress isn’t just about what happens in therapy, it’s about creating lasting change in daily life.

7 Everyday Signs Your Child’s Primitive Reflexes Aren’t Integrated

When working with children who have sensory processing challenges, autism, ADHD, or developmental delays, retained primitive reflexes often come into the conversation. But one question comes up again and again:

If a reflex tests as retained, but the child isn’t showing functional struggles… do we still need to intervene?

Let’s break this down.

What Are Primitive Reflexes & Why Do They Matter?

Primitive reflexes are automatic movement patterns that emerge in utero and early infancy to support survival and development. Over time, as a child matures, these reflexes are supposed to integrate—meaning the brain takes over control, allowing more refined movement and sensory-motor skills.

When these reflexes remain retained, they can interfere with daily functioning—impacting everything from attention and posture to emotional regulation and fine motor skills. But the keyword here is "interfere."

Testing Isn’t The Whole Picture

Just because a primitive reflex tests as retained (a “positive” result) doesn’t automatically mean it’s impacting a child’s life. Likewise, a child may pass the physical test for a reflex but still show functional signs of challenges commonly associated with that reflex.

Here’s the takeaway:

If a retained reflex is functionally impacting a child’s daily life—intervention is warranted. If it’s not affecting function? You may not need to intervene right away.

How To Decide When To Intervene

Occupational therapy always comes back to one thing: functional outcomes. According to AOTA’s Practice Smart Guidelines, interventions must be linked to real-life occupations—like dressing, playing, learning, and socializing.

So when evaluating whether to target a retained reflex, consider:

  • Does the child struggle with daily tasks related to this reflex?

  • Are symptoms of the reflex showing up in your functional checklist?

  • Is the child experiencing frustration, anxiety, or motor delays connected to this reflex?

If the answer is yes, it's time to intervene.

Real-World Examples Of Functional Impact By Reflex

Let’s walk through common primitive reflexes and how they can affect day-to-day life when retained:

1. Moro Reflex

Often called the “startle reflex,” a retained Moro can lead to:

  • Heightened anxiety or sensory over-reactivity

  • Startle responses to sounds or touch

  • Difficulty with transitions or unexpected changes

Functionally impacts: Focus in school, emotional regulation, sleep, transitions.

2. Asymmetrical Tonic Neck Reflex (ATNR)

This reflex affects the ability to cross midline and coordinate both sides of the body.

  • Challenges with handwriting, dressing, catching a ball

  • Switching hands mid-task or struggling to establish hand dominance

Functionally impacts:Bilateral coordination, school tasks, dressing.

3. Symmetrical Tonic Neck Reflex (STNR)

This reflex divides the body top to bottom and impacts posture.

  • Slouching during table tasks

  • Trouble copying from the board

  • Difficulties in sports, swimming, or toilet training

Functionally impacts:Postural control, academic performance, independence.

4. Tonic Labyrinthine Reflex (TLR)

Affects muscle tone and balance.

  • Poor core strength

  • Clumsiness, frequent falls

  • Difficulty tolerating head movements (e.g., looking up or down)

Functionally impacts:Safety, dressing, meal time, attention span.

5. Spinal Galant Reflex

Highly correlated with:

  • Excess fidgeting and attention challenges

  • Bedwetting or delayed toilet training

  • Sensitivity to clothing and tags

Functionally impacts: Toileting, sitting still, clothing tolerance.

6. Palmar Grasp Reflex

If retained, this can impact:

  • Pencil grip and writing

  • Using utensils

  • Tactile defensiveness in hands

Functionally impacts: Feeding, play, schoolwork.

7. Rooting & Suck Reflexes

These oral reflexes affect:

  • Feeding and eating (especially textures)

  • Speech and articulation

  • Oral sensitivity (aversion or seeking)

Functionally impacts: Mealtimes, speech, social participation.

The Role Of Checklists & Retesting

A best practice is to use a functional symptoms checklist before beginning reflex integration activities. After 1–2 months of consistent intervention, retest the reflex and redo the checklist.

  • Improvement in function = success (even if the reflex is still present on the test).

  • No change? It may be time to adjust your strategy or consider another cause.

Functional, Play-Based Approaches Make The Difference

Retained reflex work shouldn’t be repetitive or rote. We want children engaged, motivated, and playing; That’s how the brain learns best!

Incorporate reflex integration strategies into:

  • Obstacle courses.

  • Yoga poses.

  • Movement-based games.

  • Balance and core exercises.

  • Sensory play.

Pro Tip: If you’re a parent and your child has different sensory needs than you, establish regulation routines for both of you. Think: noise-canceling headphones for you + a sensory gym setup for them.

Final Thoughts: Look At The Whole Child

Don’t get stuck in “checklist paralysis” or rely solely on test results. Look at the child holistically:

  • What are they doing well?

  • Where are they struggling?

  • What does their environment look like?

  • How is their family dynamic?

At the end of the day, function guides intervention. Retained reflexes are just one part of a child’s beautiful, complex story.
