So the rhomburg test assesses if the patient is swaying at all. So first we'll just have them stand there and then just observe and see if they're swaying at all with their eyes open. And that looks pretty good here. So now please close your eyes and we'll observe for swaying. What you can do is put your hands around the patient so in case they feel a little unsteady, in case they were to be a little bit wobbly that you would be able to catch them. But in this case there's no swaying so that is normal, the normal rhomburg.
