nerve conduction velocity test?

I'm having a nerve conduction velocity test on my R arm this Thursday. If I understand this correctly, please correct me if I'm wrong.  If my right arm nerves fail, then there's a problem in it (pintched nerve). if my right arm nerves pass, then the problem futher up the line (spinal cord, brain). and I will probably go through more test to find it.

Do I have this right?

gee, I don't know or I'm too tired to remember - can anyone else help with this?

I just got back from the NCV test. the doc said everything looks normal, but I'll get more details when I see my PC next month. this test had little round thing on my skin then little needles that he put in my arm. he also did an ultrasound on my arm.

phoenix,

I just had an emg/ncv on my legs and the md said you can have peripheral nerve problems and of course still have a CNS problem.  He said the problems that showed up in my emg "chronic L4/5 nerve irritation on the left side"  had nothing to do with the extreme weakness in my legs.  I believe I have the answer to that now too but it could have been something to do with the central nervous system just as well.

You just have to have all the tests, i feel like im not making sense
