Understanding Neuro Report: Assistance Needed

So I got a copy of the report. It's a doozy, with all kinds of scary words, but I'm starting to realize that these scary terms don't automatically mean something bad and that I need to trust the neuro who has been doing nothing but reading EMGs day in and day out for 15 years to know what she is talking about. Here's the report, with some of my analysis at the end.=========Motor nerve conduction studies are entirely normal.EMG examination was performed in the left arm and the right leg as well as lumbar paraspinal muscles. The muscles tested were left first dorsal interosseous, left biceps, triceps, deltoid, and flexor carpi radialis, right tibialis anterior, right gastrocnemius, right vastus lateralis, right semimembranousus and right low and medial lumbar paraspinals. In the left arm, the deltoid showed rare polyphasic potentials with slightly increased amplitude and duration of the motor unit. The flexor carpi radialis showed increased insertional activity as well as polyphasics.The right leg tibialis anterior muscle showed few polyphasic units with increased amplitude and duration of the motor unit action potentials.The semimembranousus and adductor longus also showed a few polyphasics with normal motor unit action potentials.The rest of the muscles examined all showed normal insertional activity, no spontaneous activity, and normal MUAPs.IMPRESSION: This is an abnormal study. There is electrophysological evidence of chronic mild cervical radiculopathy predominantly at the C7 level and chronic mild lumbar radiculopathy predominantly at the L5 level.============Correct me if I'm wrong, but none of this showed ongoing denervation, did it? It all seems to be reinnervation. I take that as a good sign. Unless I'm wrong, in which case I hope someone corrects me. Also, my EMG from 2 years ago showed a "few polyphasic potentials in biceps brachii, triceps brachii, and deltoid on the left side." This time, the very same arm showed nothing in the biceps or triceps. You'd think if a sinister process was going on that after 2 years it would have shown not just the same thing as 2 years ago but something much worse. Progression. I don't see that.I wonder if it's possible that I have BFS and just as a coincidence I have some radiculopathy going on at the same time -- e.g., meaning that these EMG findings are completely incidental and unrelated to all of the BFS-like symptoms I am having.Any thoughts from resident EMG experts (or anyone else)?

Forgot to mention -- she did mention during the exam that she saw reduced recruitment in my leg. She also mentioned seeing brief fasics and CRDs. But none of this appeared on the report. I guess it wasn't significant enough to put on there...

Did you ahve a cervical or lumbar spine MRI recently?

Not recently. The most current lumbar MRI I have is from 3.5 years ago, and it did show some mild problems at the L5 level (mild disc bulging, foraminal narrowing) but no actual pinched nerve. Maybe it has progressed since then.I have not had a cervical MRI done recently. The most recent one is from several years ago but it showed no problems at all (or at least the report didn't mention anything). I do have a congenital fusion of C5 and C6. I don't know if that would cause problems with left arm?

Sounds like youve had some local physical nerve damage at some point and your muscles reinnervated to compensate and you healed. But youre neuro and the emg doc probably already told you that. sounds ok to me. do you have a follow up neuro visit? Im just a layperson echoing what ive read, not really knowledgable. doc should give you final reassurance.

Sounds very similar to my EMG. And the MRI's of my back and neck were fairly unremarkable.Sounds like nothing to worry about in your case.

Definitely get your neurologist to explain what the "abnormal" part of your EMG means in practical terms, i.e.: whether or not it is clinically significant. To give a counter-example, I have abnormalities on a c-spine and l-spine MRI from last Sep., but a normal EMG for my arms (only body part tested in my EMG). The abnormalities in my MRIs may or may not be clinically significant, and may or may not account for some of my symptoms. I had a round of PT based on the c-spine results but with no particular benefit. According to my docs, many people who are older will have abnormal findings on a MRI, but these have to be interpreted with caution since they do not correlate well with how a person feels. I'll be interested to hear what your doc says about your EMG results.
