Cerebral Palsy
10 Principles of Neuroplasticity: Part 2
Let’s dive right into the first five principles of neuroplasticity. Everything I write about here is found in the article, “Principles of Experience-Dependent Neural Plasticity: Implications for Rehabilitation After Brain Damage.”1
1. Use it or lose it
Failure to drive specific brain functions can lead to loss of abilities.
This principle is pretty intuitive: if you don’t actively use a functional component of the brain, that part starts to lose the ability to carry out the function it is responsible for. This is true for everyone: say you take piano lessons when you are young, but you stop taking them and don’t touch a piano for 10 years. When you try to play the piano again, you may be able to remember a little bit at best; certainly, you won’t be able to play as well as you did when you were practicing regularly. You literally lost some of the brain cells, and the connections between cells, responsible for playing the piano. You didn’t use it, so you lost it.
This is even true in the context of injured brain tissue. Researchers have found that when one part of the brain is injured, other parts of the brain can take over the function of the injured part. With rehabilitation, the brain literally reorganizes itself to carry out functional tasks.
What this means for kids with CP, is that it’s important to continue actively completing motor tasks, otherwise their brain will adapt and lose the “muscle memory” of how to complete those tasks. Of course, that’s true not just from a neurologic perspective but from a muscle perspective – keeping your brain strong and your muscles strong go hand in hand here!
2. Use it and improve it
Training that drives a specific brain function can lead to improving abilities.
This principle is also easy to understand: the brain will change in response to specific training. When a certain task is learned, the part of the brain responsible for that task grows new brain cells and forms stronger connections between those brain cells. This goes along with a change in output: the person becomes better at doing that task that is trained. Taken together with the first principle of neuroplasticity, there is a strong case for kids with CP to stay active!
3. Specificity
The nature of the training experience dictates the nature of the change in the brain (plasticity).
In this third principle, we get a little more, well, specific about neuroplasticity. The authors explain how different kinds of training can affect what changes happen in the brain. They highlight two examples.
First, the authors note how the biggest changes that happen to the brain are the result of learning new skills. In animal studies, research has shown that learning new skills yields a bigger change in the brain as compared to repetition of previously acquired motor movements. Please note that this doesn’t mean that working on existing skills is not important – remember the first principle, and look ahead at the fourth too – but rather that incorporating new skills into rehab can help maximize neuroplasticity.
Second, the authors explain that there is regional specificity. This means that if you are training a skill that uses a specific body part, for example using only your right hand, the changes that happen to the brain will be largest in the areas of the brain responsible for that movement. Since your right and left sides of your body are controlled by the opposite side of your brain, that means working on something with your right hand is going to make the biggest changes to the left side of the brain, and vice versa.
4. Repetition matters
Change (plasticity) requires sufficient repetition.
Think back to any time you learned a new skill. It could be writing the alphabet, playing the piano, learning to drive, anything. Did you perfect that skill after practicing it just a few times? Probably not. You had to practice it many times before it felt natural and easy to you. That’s because lasting, meaningful neuroplastic changes only happen with repetition.
The same process is at play when learning motor skills. It is not enough to practice going from sit to stand just a few times and expect to have mastered the skill. In order for a child’s brain to undergo meaningful change, it is critical for the skill to be repeated many times.
5. Intensity matters
Change (plasticity) requires intensive training.
Here’s an interesting fact about neuroplasticity that you can impress your friends with. There was an animal study where researchers studied brain changes following practice of a skilled motor task. They divided the animals into two groups: one group completed the task 400 times per day, and the other group, 60 times per day. They found that the animals in the first group had a measurable increase in connections between brain cells in the part of the brain responsible for that task, whereas animals that completed the task only 60 times per day did not.
The takeaway here is that kids with CP need pretty high intensity in their motor program in order to make meaningful changes in their brain.
Phew. We made it through the first five principles of neuroplasticity!
Before we move on the next five, I’d like to pause and consider how the ideas seen so far connect with what conductive education offers. Kids who come to the Center practice a wide range of motor tasks regularly, in a highly intense fashion, with lots of repetition of many familiar tasks, while also being given opportunities to learn new skills on an individualized basis. From what you’ve just read, I hope it’s apparent that conductive education capitalizes on every single one of the first five principles.
Stay tuned for the last installment of the neuroplasticity series!

Loyola Magazine Article
Recently the Center’s founder, Patti Herbst, was interviewed and featured in Loyola Magazine’s Alumni Voices. In the article, titled Giving kids what they need most, Patti shares her personal experience about when her son was born with cerebral palsy, and how she and her husband, Chuck, learned how to help him achieve independence. Her story tells how this discovery led her to help hundreds of other children with physical disabilities.
Here is an excerpt:
‘I’ve learned so much over the years through my work, and as a parent, about children with physical disabilities. Sometimes people have the misconception that these children aren’t happy, and as parents, all we want to do is make sure our children live full, happy lives. But children with cerebral palsy and other developmental disabilities are still first and foremost children—they are full of awe, wonder, joy, and laughter. And people with disabilities are just as happy as anyone else.’
Gravity and Cerebral Palsy: How it Affects your Child
Gravity is powerful.
You might be wondering: why is gravity special to people with cerebral palsy? Gravity affects everyone, right?
It’s true that gravity affects everyone. Gravity is where our muscle strength comes from. Think about typical development: all major milestones related to movement are different versions of working against gravity. Pushing up to hands and knees. Pulling to sit. Pulling to stand. Those are all movements against gravity, right? Gravity is the force that our muscles are pushing against, which is where muscle strength comes from. Think about how weak astronauts are when they return from a long trip outside the atmosphere: it’s because their muscles have very little opportunity to fight against something.
Gravity’s Affect on Individuals with Cerebral Palsy
Gravity affects kids with cerebral palsy in several ways. First, because their muscles aren’t quite as strong and have a harder time coordinating, it’s harder to fight against gravity to complete those major milestones. As a result, kids with CP spend more time in positions that are gravity dependent. This means that unless the right positioning equipment is used, young kids with CP tend to spend more time either lying down or lying back in a reclined position. This simple factor of not being in an upright position can have lasting effects on alignment. Did you know that this affects rib cage development? When we are born, our ribs are in a horizontal position. As we move through typical milestones to be able to sit and stand, gravity pulls our ribs so they angle down. Go ahead – feel your ribs right now and you’ll feel that they are pointing down. This is the ideal position for our ribs to support our lungs as they move out and in for normal breathing. If kids with cerebral palsy aren’t given the opportunity to be in an upright position as they grow, the ribs will stay horizontal which makes breathing harder.
Another major way that gravity affects many kids with CP is later in life during walking. “Crouch gait” is a very common feature of CP, and it’s pretty much what it sounds like: the child walks with their knees bent. There are several causes for this type of walking pattern, like growth spurts and spasticity, but gravity is also a major influence. Because gravity is pulling the body down, the knees bend, and leg muscles have to be strong enough to overcome that pull. Since kids with CP tend to have weaker muscles, gravity might be so strong that the knees are not able to straighten out.
Those are just two of the biggest ways that gravity affects kids with CP, but there are so many more since every movement we do is done against gravity (unless we are swimming, or happen to be in outer space!). Even if we are just sitting, our head and torso need to work to stay upright.
So what do we do about it?
The first thing is to be sure to get the right equipment from an early age. Children who are not sitting by 6 months should get adaptive equipment to allow them to sit upright, and if they are not standing by 12 months they should get equipment that supports them in a standing position.1 Adaptive equipment will allow them to be positioned against gravity, which not only supports correct rib cage alignment, but also helps them work on trunk and neck control, and allows them some opportunity to bear weight to help keep their bones strong.
The second thing is, of course, therapy! An intense motor program like what is offered at the Center for Independence will work on strengthening muscles to be able to overcome gravity and will address their ability to do all the antigravity movements of pulling to sit, pulling to stand, walking, and so on.

On the Table 2018 – “Getting my Wheel in the Door”
Getting my Wheel in the Door
Being a person with a physical disability, I know the struggles the disabled community faces when it comes to fully-participating in society. While our communities are more accessible than in the past, physical barriers still remain. It makes me wonder: what obstacles exist in our communities that our able-bodied friends do not encounter? If we, individuals with disabilities or those that use assistive devices, cannot “get in the door”, we cannot fully participate.
On the Table Conversation
This year, I led the Center for Independence staff in a discussion for On the Table. The theme of our conversation was about accessibility within our communities. I asked my co-worker’s thought-provoking questions such as: What barriers exist in our communities for individuals that use assistive devices? How are we as a society spreading awareness to able-bodied individuals regarding these restrictions? And lastly, how can we resolve the issues surrounding accessibility so all community members have equal access?
Americans with Disabilities Act (ADA)
“Legislation passed in 1990 that prohibits discrimination against people with disabilities. Under this Act, discrimination against a disabled person is illegal in employment, transportation, public accommodations, communications and government activities.”
With the passing of ADA in 1990, guidelines were set that required accessibility for anyone who uses any kind of assistive device. Doorways, aisles, and hallways need to be of a certain width for patrons who use mobility devices. Restaurants should have tables that are high enough for a wheelchair to fit under, and so on. But often, just because there is a sign saying an establishment is accessible, it does not necessarily guarantee it is the case.
If a person using a mobility device has to use a back entrance which is primarily used to take out the trash, it most definitely should not be considered accessible. If someone is physically unable to open a door, and there is not a push button available, this makes them physically dependent upon someone else to open it for them. As my friend and fellow social worker, Kathleen Downes, MSW so eloquently articulated: “Accessibility is about addressing architectural and physical barriers. Inclusion is about having welcoming attitudes to match. One is meaningless without the other. Inclusion and accessibility rely on one another.”
Breaking Barriers to Accessibility
You may not personally use an assistive device to access the community, but you most likely know someone who does. A mother pushing her infant in a stroller, an elderly person who relies on their walker, or perhaps a friend with a disability who uses a power wheelchair. We can all benefit from reducing or eliminating barriers within our communities to create a more inclusive environment. My mission, which emerged following the “On the Table” discussion this year, is to spread awareness of these accessibility barriers and work to eliminate or reduce them. Let’s work together to open doors for all!
Please feel free to continue the conversation and share your comments, thoughts or personal experiences related to accessibility.

The Center Celebrates 20 Years!
Dear friends of the Center,
This year marks the Center’s 20th anniversary! We’ve grown from serving six children out of a local church to over 250 children per year at four locations throughout the Chicagoland area! What an amazing adventure, filled with so many wonderful people and beautiful moments.
In 1998, our original Board of Directors made a pledge that the Center would never turn a child away due to lack of insurance or inability to pay. Generous donors like you have allowed us to keep that commitment! Over the past 20 years the Center has served over 650 children and young adults with physical disabilities and given nearly $11million in charitable services. The Center has been a safety-net for children who are often turned away.
The Center is grateful to the many people who have helped our program grow and flourish: our Board of Directors; generous donors who support our program; talented professional staff who help children achieve their highest level of independence; and finally, parents who entrust us with their children.
Learning that your baby has cerebral palsy can be incredibly devastating for young parents and often results in many stressful unanswered questions: “Will my baby be okay?” “Will my baby grow up healthy and included?” “What does the future look like for my child?” The past 20 years have proven that despite challenges, the future is bright!
Families raising children with physical disabilities should dream big! Kids with cerebral palsy are happy, engaged, curious, and full of joy – just like their able-bodied peers. We have celebrated alongside families as their child achieved milestones including high school graduations, transitioning to college, entering the workforce, and living in the community independently. Given the opportunity, children with physical disabilities can do anything that they set their mind to – we witness that each and every day at the Center!
Thank you for your support over the past 20 years – your kindness has allowed us to help families believe in endless possibilities. We look forward to sharing many success stories of independence for years to come!
