Got my EMG test results. Can anyone translate them for me...?

OK I got my EMG test results in the mail today. Can anyone help tell me what this stuff means?

I'm not going to copy out the whole thing, just some main parts and the Neurologist comments. I will of course ask my NS too, but the appointment is not for a few weeks.

Any time there is a ∆, it is because i could not work out how to type an up arrow.

EMG REPORT - Left Arm:
-----------------

NEVER CONDUCTION STUDIES: Normal

NEEDLE EXAMINATION:

L First dorsal int....... Insert aciv = NL, Spont. activity, Fibs = 0, Fascic = 0, Motor Units = NL, Motor Unit Potentials Recruit (Blank)

L Pronator Teres....... Insert aciv = ∆, Spont. activity, Fibs = +++, Fascic = 0, Motor Units = (blank), Motor Unit Potentials Recruit = -1

L Flexor carpi radialis....... Insert aciv = NL, Spont. activity, Fibs = 0, Fascic = 0, Motor Units = NL, Motor Unit Potentials Recruit (Blank)

L Triceps (lateral head)....... Insert aciv = ∆, Spont. activity, Fibs = +, Fascic = 0, Motor Units = NL, Motor Unit Potentials Recruit (Blank)

L Biceps....... Insert aciv = NL, Spont. activity, Fibs = 0, Fascic = 0, Motor Units = NL, Motor Unit Potentials Recruit (Blank)

L Deltoid....... Insert aciv = NL, Spont. activity, Fibs = 0, Fascic = 0, Motor Units = NL, Motor Unit Potentials Recruit (Blank)

SUMMARY: Nerve condcution studies were normal. Needle examination revealed increased insertional activity and fibrillation potentials, in left C6 innervated muscles with reduced recruitment of normal motor unit potentials.

INTERPRETATION: The EMG Findings were those of an electrophysiological moderate in severity acute left C6 radiculopathy. Active denervation is prominent, but that does not necessarily reflect ongoing compression and correlation with current imaging is required.

EMG

My very amateur interpretation is that the EMG suggests possible problems generating from the C6 vertebrae/area. What symptoms are you having and do they correlate with C6 nerve impingement? Look for a cervical dermatome chart on the internet which will show you where you may feel symptoms of C6 (and other cervical levels). Do you have a follow up with an Orthopedic Spine Surgeon and/or Neurosurgeon?

Hi, Yes I have C6 symptoms,

Hi,

Yes I have C6 symptoms, muscle weakness and some atrophy of C6 innervated muscles.... and have had them for 3 months now. I was just wondering if this EMG shed any light on the type of damage to the nerve, and might help in classifying the type of injury i.e. Neuropraxia, Axnotmesis, Neurotmesis

Hi TonyDisc ~

When do you see your doctor for an interpretation?

MRI

Have you had a cervical MRI? If that showed a disc problem at c6 (or problem with vertebrae/surrounding tissues) then it can be simple nerve impingement and not classified as some of the advanced type of nerve injury/problems you mentioned. Many of us here have had MRI and then EMG to collaborate the fact that the disc/vertebrae problem at a specific level matches up with nerve conduction results from the EMG.

yes I had an MRI. A

yes I had an MRI. A herniated disc was found at C6 2 and a half months ago, I was operated on almost 1 month ago. The EMG was done before the surgery but I only asked for a copy recently.

What has me confused is normal Nerve Conduction, but abnormal needle findings. Not sure what that means.

Hi again ~

This is how I, (no medical training Gwennie) would understand your report:

You had (I assume) two tests: one was the nerve conduction study which was "normal." This test indicates the speed at which the nerve is able to transfer the signal to the muscle.

The EMG portion of the test measures the electrical activity in muscles. This would be what is referred to as the needle findings. The summary indicates that the findings indicate that there is moderate acute radiculopathy at the C6 level. The writer goes on to say that the results of the EMG need to be interpreted in relation to what the MRI studies are indicating.

I do not see any indication that the report sheds light on what type of nerve damage is affecting C6 except to say that he cannot tell if decompression is still going on without seeing the MRI studies.

...at least, that's how I understand it. Wink

Oh, one more thing: the nerve conduction study indicates the condition of the best surviving nerve fibers.

Hi nealexus.

Hi nealexus.

We are not doctors and are not allowed by the rules of this forum to make an interpretation of medical reports. Your doctor will explain it to you.

I was diagnosed with progressive (ongoing) severe nerve damage.

This data is a list of test results of two muscles tested on both right and left legs.
This link provides more detail. http://www.spine-health.com/forum/pain/sciatica-leg-pain-radiculopathy/new-member-help-test-results

"The EMG study will help evaluate active versus inactive spinal nerve damage as well as localize the spinal level of nerve damage. It will also help assess for any coexisting peripheral nerve damage." See http://www.spine-health.com/blog/emg-study-ongoing-pain-after-spine-surgery-due-nerve-damage
