Dr. Rick :

Hi. I'm online and happy to answer your question today.

Dr. Rick :

What that test does is look for problems with proprioception and coordination that may be due to being intoxicated. By closing your eyes visual clues as to the relationship between your moving finger and your stationary (hopefully :-) nose are removed. In this situation the major way to correct the trajectory of your finger toward your nose is with the system of receptors and nerves that let you know where in space your finger is and how it is moving.

Dr. Rick :

Sober folks can easily perform this task. Intoxicated folks can't.

Dr. Rick :

Does this make sense to you?
