Hi Wren, since you were brave enough to ask the question I will try to answer as best as I can for you and everyone else who didn't ask but probobly wants to know. It's kind of hard to describe what the gait (the way they stand and walk) of a person a spastic CP looks like, but I'll give it a shot.

Basically I'll describe myself starting from the feet up. Kayla is a little bit different from me, but this should give you a basic idea. Many of the tendons in my legs like the Achilles tendon in the heal and hamstrings in the leg never grew to full length. This is very common in CP. So I can not put my feet flat on the floor. That is why many people with CP walk on their toes. Basically my feet are pulled up as if I were in heels when when I'm not. My feet also turn in slightly the way a baby walks. Braces over the years have lessened that to the point most people don't notice that part anymore, but I see it in me every day. My legs also bend at the knees when I walk. In my case it's about an 80 degree bend at my knees. That's because of the hamstring length. Moving up from the legs, I have lower gross muscle control in my trunk muscles (around the hips). This means I can't use the same muscle movements other people do to walk. So I use hip movements to shift each foot forward. Because of the way my feet fall to the ground quite hard with the exaggerated muscle movements, there is a very distinctive "horse clomp" to my walk. You never forget that sound once you know what it is. I can hear someone coming with spastic CP long before I spot them most of the time..

Here is a good video of an adorable little girl with similar CP walking:

Towards the end of the clip there is a good side shot as she walks by, and you can see how her feet land as she steps and how her legs bend. You might also notice that her hip movements get more extreme there at the end. That's a sure sigh she was getting tired. At that age I would have had to be carried back after a stroll like that, but I also flatly refused crutches until I was 17.

Kayla's feet probobly turn in more and her legs probobly bend more then this little girls do. She was never encouraged to play and really use her legs between therapy sessions like I was and I'm sure the angel in the video was.

The random tiredness and spurts of energy depending on the day have already been touched on in the story. The shakiness of her hands have been explained as well. Any other effects that Kayla has to deal with I will leave to Bailey to explain in the story. CP is a major umbrella term that has a lot of different effects it can have on different people. I would guess her handwriting is absolutely awful, and she likely has random muscle spasms called clonus. There are days I can thread a needle no problem, an there are days that the act of grabbing a bottle of lotion off my vanity has me knocking everything within arms reach onto the floor. It's actually the randomness of it that is the most frustrating.
