Dear Kitt,

I just looked it up online in a neuro site. I cut this sentence.

Edema, skin lesions, and obesity are limiting factors
in performing a successful EDX study.

It also states that temperature is a major factor in getting proper results.

My first NCS was very different than the ones by other docs. The last one said he would never do an NCS without also doing an EMG. He also said some other things that I just can't remember at the moment.

The article was in Practical Neurology January/February 2010 issue and is titled EMG and Nerve Conduction Studies in Clinical Practice by Rossitza, MD,MS and Lara Katzin, MD

It is an interesting article but most of it is way over my head.

I couldn't find the article. I found Practical Neurology but not the article. Perhaps it is what they are looking for when the testing is done. As you probably know, there are many conditions that they would use EMG/NCV testing. I understand about the temperature thing. It wasn't a factor when mine was done. But was for others I know of. It also matters a lot as far as who is doing the testing.
