Well, the EMG tells the doctor whether the myelin sheath is being damaged,

type 1 and and others, OR the core of the nerve is being damaged, type 2 and

others.

Examples:

Deylinating = ....Type 1, 1-A, 1-B, 1-C, and, 1-X

Axonal = Types 2, 3, 4, 5, 6, 7

Hi Kat

I am sorry I have to disagree with you, an EMG test is an electrical test of

the nerves. One cannot see the mylen sheath, therefor they cannot give an

accurate diagnosis on what type of problem exists. The only thing they can

tell is if the nerve action is slowed. Does that make sense? If a diagnoses

was made through this method it could have been prior to DNA testing being

available, and then they would at best guess after a process of elimination.

I hope this will help with your diagnoses. A DNA is positive, no room for

error, and less painful. Mind you I am only trying to help, not say you or

anyone else are wrong, God Bless-jr

e-mails to the list to you to read about CMT and the use of EMG's and NCV's

in diagnosing. One is from a genetic site. http://www.geneclinics.org/

Please check it out and read where it states, " The diagnosis IS based on

clinical AND EMG/NCV caracteristics " ~>Becky M.

Lamar here,

I disagree,

DNA testing is only accurate for the types it tests for. In addition the nerve

conduction velocity is slowed by demylenization. It is only slightly decreased

or normal in axonal types. You do not have to see the sheath to test it's

function. The fact remains that there is no one test for CMT. Many were

accurately diagnosed years before the DNA test was available. For an accurate

evaluation you need evaluation of family history (if any), evaluation of

symptoms, NCV, EMG, and DNA tests. DNA tests are often not indicated with

proven family history. For instance: if you have Type 2, there is no need to

test your children for type 1 and X linked.
