I understand what you mean about Liza Jane's worksheets...they were intimidating to me at first also. BUT, once you learn a bit more, and what it all means, it will make sense and fall into place.
Start by clicking on this site:
www.Neuroexam.org It's a site that explains what all neuro's do, test and look for during each step of diagnosing PN and other neuro conditions.
Also, read the 'stickies' at the top of this category, they are chock full of good info.
You are on the right path from what you've said so far. - j
