To give you an idea about genetic variation between each of us, there are about three million differences in our genetic code. They go to influence the color of our hair and the color of our eyes, the way we walk.
Babies develop about 80% of their brain growth over the first two years of life, and it's also when all the connections in the brain, what we call the white matter, which is the cables in the brain, grow and develop and connect to the cortex.
It's really hard just to watch someone walk to decide what's wrong with them. A better way is to do what's called Three Dimensional Gait Analysis, and that's where the child comes into one of our labs. Here, we put markers on their face, hands, and legs. We have a computer and a bunch of cameras all around the room. And then we're able to break down the gait into three dimensions.
Spasticity is a condition of muscles that is a velocity resistance to stretch. What that means to a child and to a parent is that if you move the limb slowly, you have a difference than if you move that limb fast. Spasticity restricts movement and it creates a break on the system. It's as if they're trying to move, but they're held back. By treating spasticity, you may improve the range of motion or the action of the movement.
It's really essential to understand how brain function works to really tap into how learners learn.
One of the things that we typically forget when we look at kids who have conditions like CP, is that they're first and foremost, children.
Sleep is important to all of us, but it's especially important for infants. When infants go to sleep, they start to create neural networks about what they've been learning during the day. It's estimated that as many as one in five children with disabilities have a sleep disorder, and that's higher than the rate of typically-developing children. Finding sleep interventions for these children is incredibly important so they can lay down their brain networks and continue to learn during their early childhood years.
It is important to understand the brain injury for each individual person, because they can be really different. Where the injury is can give us important clues to what motor problems that individual will have. The time you have the biggest risk to having a stroke is as a baby, not as an adult so it is important to understand what may be happening in the infants brain.
Cerebral Palsy affects body movement, muscle control, muscle coordination, muscle tone, reflex, posture and balance. Depending on the part of the brain that is injured depends on how someone’s muscle tone will be effected. For people with spastic CP they have increased muscle tone because of the part of the brain that's injured. If causes very tight muscles which in turn effects the movement of the joints and of the limbs. For others who have dyskinetic CP they lose the ability to have voluntary control over their muscles, and they can have jerky and uncontrolled movement patterns.
If your child has cerebral palsy, there's a good chance that he or she will have a hip x-ray at some point or they may even require regular hip x-rays. It is important for you to understand the different components of a hip x-ray. Your doctor will be looking at the hip joint itself as well how well the bones are growing.
The spine is made up of many individual bones called vertebrae joined together by muscles and ligaments. Flat, soft discs separate and cushion the vertebrae from rubbing against each other. Because the vertebrae are separate, the spine is flexible and can bend. Together the vertebrae, discs, muscles, and ligaments make up the vertebral column or spine.
A lot of parents don't realize that their baby, all the skills that they have. So they can look at you, they can follow you. They're already starting to imitate you, and through the first few months of life, they're already starting to learn to reach and grasp toys, and to have nonverbal communication with you.
Children with cerebral palsy experience brain damage around birth or before birth. So the language of the brain in other words, the way they will move, will be different from typical movements. So by looking at their movements, we will understand that there is something that is wrong in the brain.
In general, children with cerebral palsy will have stiffness around the hips and they tend to develop atypical hip positioning as a result of their spasticity. They will develop hip flexion contractures, abduction contractures, and they will have difficulty with seating as well as bathing and hygiene.
