The test can also be googled up. It involves placing needles that arn't very big into parts of the affected limb. A small electracal volt is passed through these needles. This will tell if nerve function is being compromised. The test can hurt for some, and not for others. From what I understand is isn't pleasant, but can be tolerated well. For DX and receiving SSD, etc. it is probably a good idea, for your qualification. I passed on the test, but for me the docs, could easely see what was wrong with me without it. I wish you all the best. ginnie
