--sounds very much like qualitative (sometimes also called quantitative) sensory testing; perhaps they have some technology over there that has tweaked it a little, but it doesn't sound like anything new.

Take a look at:

(though this is by a device manufacturer for doing the test, the description of the process is succinct)

(I include this one as it shows that at least some insurance companies don't think the reliability/validity of the procedure is all that good--more on that below.)

(This last one mentions Dyck's system and also Von Frey Hairs, which almost no neurologist even knows about anymore.)


I had such testing done when I was in the midst of my acute neuropathy phase; my results were within normal limits though the skin biopsy had indicated some rather abnormal results. Many of the reviewers have noted the necessity of skilled interpretation of testing results and the rather subjective nature of patient responses to the stimuli in doing these tests.
