Post 23: Rethinking AFOs: A Fascia-Informed Approach for Children with Cerebral Palsy
We want flexible and relaxed feet, but we place them in rigid AFOs all day long.
It's a paradox, isn’t it?
We say we want our children's feet to move better. To gain range. To improve alignment. But what do we often do? We strap them inside a rigid plastic shell all day long.
Imagine for a moment that your own foot was placed in a cast—not because it was broken, but just to "keep it aligned." How long before it started to feel stiff? Weak? Disconnected from the rest of your body?
The truth is: Movement feeds the fascia. And fascia feeds function.
If we want better movement, we have to allow movement.
From Biomechanics to Biotensegrity: A Paradigm Shift
Most of us were taught to see the body through the biomechanical model—a system of levers and joints, where muscles move bones and orthotics correct misalignments. That model sees a foot in equinus (pointed down) and says, "Let’s strap it into neutral."
But the understanding of fascia and biotensegrity brings something different.
In the biotensegrity model, the body isn’t held up by rigid bones but by a dynamic balance of tension and compression. Fascia is the connective tissue that forms this tensional system, holding bones apart to create space for movement. Without that space, joints can't move freely.
If your child has CP, chances are their fascia isn't offering the stability they need. So, they compensate by tightening muscles—using tone to create stability. It's not a mistake. It's brilliant.
Now imagine putting an AFO on that foot. Yes, it "corrects" the position. But the underlying tension? It's still there. And it has to go somewhere.
When fascia can't hold, muscle tone kicks in.
When movement is blocked at the foot, forces travel to the knee, hip, or torso.
When we restrict natural movement at one joint—especially with rigid orthotics—the body doesn’t just stop moving. It compensates. That tension travels. The fascia, in its effort to create balance, transfers the force somewhere else: often to the knees, hips, or pelvis. What looks like a harmless brace can, over time, contribute to joint misalignment and structural changes that impact your child’s development.
This is why we often see hip issues in children who wear AFOs all day long. Their foot can’t express the tension, so it travels upward. Their knee gets loaded in unnatural ways. Their hip becomes the next available outlet. And because fascia connects everything, what starts in the foot can echo all the way to the core.
This is how red marks on the foot, shiny skin, or even hip subluxations can begin. When you remove your child's AFOs, do you see those red marks? That is their tissues responding to pressure. That is your child’s body fighting the restriction, looking for another way to stabilize. It’s their intelligent system doing its best to compensate—because when the feet are blocked, the body doesn’t give up. It adapts. It pushes, it strains, it finds a way. But sometimes that way leads to more stress higher up the chain.
The Hidden Lesson of Dusty Heels
Ever found dust in the heel pocket of your child’s AFO? That’s a clue.
It means your child’s heel isn’t touching the bottom. Why? Because the AFO was moulded in a passive position, and when your child activates (moves), they don’t have that range. The tension lifts the heel. Yes, it looks "aligned" from the outside, but inside, the tension patterns are still there, stressing your child's body even more.
Free the Feet, Feed the Fascia
Here’s the most important shift I want to offer:
Small movements feed fascia.
And fascia is the key to mobility, function, and postural control.
When your child's foot is free to move—even just a little—you are feeding the fascia with what it needs: subtle shifts, micromovements that bring hydration, nutrients, and proprioceptive signals into the tissues.
You don’t have to be a therapist to help your child. You just have to let their feet move.
Some examples:
The small flex-and-release that happens when your child rests their foot on a sponge
The bounce of the foot in a fabric hammock under the stroller
The tiny shifts when their feet are placed on a vibrating surface
All of these feed the fascia in ways a rigid shell cannot.
When AFOs Might Help (and When They Might Not)
This is not a call to ditch AFOs entirely. Some children benefit from them, especially for short periods during specific activities.
Let’s break it down:
✅ Use AFOs When:
Your child needs extra support to walk and they do better with AFOs on
You’re doing standing or weight-bearing therapy and need external alignment
Your child moves better and more confidently with them
🚫 Avoid AFOs When:
Your child is kneeling or crawling (this creates strain on the knees)
They're sitting for long periods in a stroller or wheelchair
They're riding a bike (let those ankles move!)
Rule of thumb: If the activity requires free movement, let the feet move. Use AFOs only when they truly help.
What About Children Who Aren't Walking Yet?
If your child isn’t walking or bearing weight regularly, we need to ask: what’s the goal of forcing a 90-degree foot position all day?
In these cases, AFOs may:
Limit small, healthy micromovements
Disrupt fascial flow
Send unnecessary tension up to the hips
Flat feet aren’t required for walking. Some children walk beautifully on their toes.
The goal isn't "perfect alignment." It's healthy, nourished tissue that allows function.
Final Thoughts: Not All Support Comes from Braces
We all want what’s best for our children. And for many years, I believed orthotics were the best way to support a foot that looked "wrong."
But fascia changed my mind. Now I know:
The body compensates wisely.
Holding a shape isn’t the same as having function.
Movement—even tiny, hidden movements—matters.
So if you choose to use AFOs, do so with understanding. Give the feet some time to breathe. And always, always remember:
You are your child’s best guide. You don’t have to choose black or white. You can explore the gray with knowledge, curiosity, and care.
