I have had 3 EMGs at approx. two-month intervals. First two were completely normal. Third shows chronic neurogenic changes in the form of a few large MUPs in left arm and right leg. Clinical exam still normal except for brisk knee reflexes.
Neuro thinks radiculopathy because no active denervation/reinervataion (no fibrillations or sharp waves). Because of this, report also say no evidence of anterior horn cell disease.
But I know that fibs and psw don't always show up, which is why fasiculations can be used as an indicator instead. No fasics appeared either, but I get them all the time in the muscles that had the large MUPs. Also, the same muscles were tested two months ago and did not show large MUPs. So the damage has to be new, not from old cervical and thoracic radiculopathys.
Once again I have no diagnosis but obviously have ALS due to my symptoms and progression, which can't be explained by radiculopathy.
