Cerebral palsy is an injury to the brain, but what we find is that it has a lot of effects on how you use your muscles.
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.
I'm going to be talking about AAC and reading and some different things that you might not think about when you are doing those types of activities. When you're supporting reading for a nonverbal child, whether they use a high-tech system or a light-tech system, like a paperboard, you want to make sure that they have plenty of the opportunities to contribute to the experience.

Every educator needs to make a decision about technology they need to put in place. They're not sure if they should put Option A in place or Option B in place.

When you don't have enough evidence about a student's performance, assume they can do whatever you're asking them to do.
