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.
