Thanks

Brief Answer:
Not permanent damage
Detailed Answer:
Hello,
I have gone through your question and understand your concern.
Acute signifies recent damage and chronic means long standing disease and associated changes.
Even acute condition may be having poor recovery and chronic disease may have a better prognosis.
No direct relationship with nerve damage and recovery.
The improvement depends upon the disease.

How can I determine reason for the constant changes? Why is the use of MRN not common which I understand will you give a better picture of nerve issues. Thanks Dr!
How do you distinguish between recent damages being mild or Med or worst since acute doesn’t seem to reference damage being acute? How do you measure level of damage to nerves in emg test?
Thanks

Brief Answer:
EMG may be slightly helpful only
Detailed Answer:
Hello,
MR neurography is a new technique and interpretation and correlation of findings is difficulty as the nerves are very small and thin.
In EMG, acute changes may have fibrillation potentials and amplitude which is larger than chronic injury.
Also chronic cases shows polyphasic finding body MUPs.
