So, I just want you to be relaxed, okay? You need to put your hands down at your sides for me or put your feet together, okay? Do you wear contacts, glasses, glass eye, anything like that? Okay. Now, this test is just going to test your eyes, okay? So, I'm going to hold a stimulus, a pen in front of your eyes. I need you to follow the pen with only your eyes, all right? Don't move your head, nothing like that, okay? Just stare straight ahead. Use your eyes to follow the pen back and forth, okay? Any questions? I'm going to give you some instructions, okay? Uh do you have any issues walking? Are those shoes okay or comfortable to walk in any of that? All right. And no leg injuries, no ankle injuries, nothing like that? Okay. All right, so I'm going to put you in the starting position, then I'm going to explain the test, okay? When I put you in that position, I want you to hold that position for me until we begin, okay? All right, so I would need you to imagine there's a straight line right in front of us, okay? I want you to put your left foot here just at my line, okay? That's it. Your left knee can be bent a little bit. That's all right. When instructed to do so, you're going to take nine heel-to-toe steps forward. Okay. Take a series of short steps heel to toe and turn around, and then walk back nine heel-to-toe steps counting out loud, okay? I'm going to demonstrate. Hold this starting position. I'm going to take three. You will take nine, okay? I'm going to look like this.
