Confused after Nerve conduction test.
 

I went for a nerve conduction study test yesterday and the results all came back pretty good, they said there was no nerve damage and only slight delay on the left side. He said that means that all my TOS is more arterial and Vascular, but what i dont understand is if thatsthe case then why do i still get pains like from my neck to fingers?

Can vascular/artery compression cause those kind of pains?

EMG's are rarely positive for TOS. So you can still have neurogenic TOS as it is the more common form. My physiatrist told me earlier this year that he's probably only seen 5 to maybe 10 positive EMGs for TOS in his practice. I am one of those 5 to 10 positive cases. He dxd me with TOS in 2004. I've had surgery for that side and it's doing great. Since then, I've developed TOS on the other side and went back to see him.

Even slight inhibition of blood supply can cause the muscle it feeds to spasm or become hypertense due to lack of oxygen needed to form and consume its ATP. Once a muscle contracts, it can remain contracted (shortened) forever without using any more energy; it needs a shot of energy in order to relax again, and lengthen to its normal resting state.

A chiropractor that posted on a forum in the past, used to explain some of the TOS pain/symptoms this way.
He was an expert and treated many of the Florida sports teams members.

He used a weight measurement but i can't recall the amount it was.

He said it only takes x amount of pressure/impingement/compression to cause a nerve to send out pain/symptom signals. It was a very small amount is all I can remember...

Have had two EMG and NCV tests. Both normal. Still in pain. Only real use is eliminating other culprits.

after dealing with TOS for about a year and half now i have realised this, static postures and repedative anterior movements cause pain. I met one other person in my city who had TOS, he was a massage therapist for many years and as a result he got TOS. he told me it took 9 months off no work and treatment to get back to a point where he could work again.. So think at some stage i might have to bite the bullet and not work at all and really combat this thing once and for all.

Jo mar do you happen to have a link to the posts from the chiropractor that your talking about ?

Hello hellothere,
my EMG tests only picked up that I had mild carpal tunnel on my right side and that was it.
I do have arterial/venous TOS however and symptoms that sometimes feel as though I have nerve damage/ impingment.
So yes, I'm also very confused as to how they can seem to measure pain.
What is seen as being a negative result certainly doesn't feel like nothing.

No, that other forum had a major crash and all those posts were lost.:(

Basically he agreed with the sticky tissues/adhesions theory and the FWH/FWS posture playing a part. (forward head/forward shoulders)


On the EMG/NCV testing, another point was mentioned in the past by others, it tests mainly the large nerves and not the smaller sensory nerves that we get many of our problems from.
