Well, we're certainly learning as we're using it. We like to listen to the patients on what their needs are. They help us to determine what programs we have to develop. It's based on the feedback we get from them.
Certainly if you have a Wii machine, it's the same idea. You're interacting with a screen. Then the next generation had an avatar of yourself in the screen. Here there are some programs where you're actually in the screen because we can put the markers on.
I took a group to Israel to see how they used theirs, and theirs were much more primitive than this. We have two treadmills. Our platform moves in many more directions. Certainly as we're using it, we're finding things, and we're giving feedback to the company as well.
I don't remember whether we have a pneumatic system. It originally came with one system underneath it to move the actuators. It didn't work and it had to be changed, and the company changed it for us.
