Does my NCS and EMG results show Neuropraxia?

I had a Nerve Conduction Study and EMG done recently because of nerve root compression due to cervical herniation.  The Nerve Conduction Study came back normal.  The EMG needle showed active Denervation.

MY QUESTIONS:

1.  If my nerve is conducting normally but the muscle is not receiving the signal, does this mean that my nerve root injury is Neuropraxia?  I ask this because it appears that my nerve is intact since it can still conduct properly.  If it was axonotmesis, then the nerve conduction study would have been abnormal, is this correct?

2.  If my injury is neuropraxia, and is localised only at the nerve root, then what kind of timeframe should i expect until recovery?  My symptoms now are arm weakness persisting for 3 months.  But if the neuropraxia recovers, does that mean the nerve will then be able to communicated with the muscles, and this would produce a normal EMG needle test?


Thank you



For your reference Here are the Doctor's notes:

SUMMARY: Nerve conduction 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.

Dear Friend,
Well what all you have said is correct. Neurpraxia is a physiological event where axonometesis and neuronomatisis  are anatomical event, ie real discontinuty in the transmission.
However the point is that in 6 hours, the praxia may worsen to an irreversible condition. We agree that the nerve grown at a speed of minimum of 1 mm per day, however it variess as per the stimuli of nerve growth.
The rules of regereration states that .....the sooner the recovery, the better is the completion the recovery. Also recovery takes maxinum 12-18 months. Hence we need to wait till that time.
However, the cause of the compression(disc in this case), needs to be removed. The sooner the cause is removed, the better are the chances of recovery.
I hope your query was resolved. Still if you have a slightest doubt, please ask again.

The compression was removed after 2 months.  It is now 1 month since it was removed, but still no improvement in strength.  This is why I am confused.

If the compression is removed, and if my nerves are still conducting normally, then why is the praxia region not healing?  

thank you.
