Question 1

what does a emg test show?

Accepted Answer

EMG: An electromyogram (EMG) measures the electrical activity of muscles at rest and during contraction.

Question 2

emg/ncv test will show what exactly?

Accepted Answer

See below: Ncv, or nerve conduction velocity, is an electrical diagnostic test that provides information about abnormal conditions in the nerves.

Emg, or electromyography is a technique for evaluating and recording the electrical activity produced by muscles.

Question 3

would a emg/ncv still show issues if cubital tunnel symptoms are not currently present? my symptoms come and go and werent present when i had my test, which showed no issues?

Accepted Answer

: I would think not, Can always repeat or before undergoing torture I would ask dr who knows you.

Question 4

can an emg/nerve study show no abnormalities despite ongoing pain? does this suggest mild nerve irritation or insignificant nerve pressure that may not be detected by the test? is the test primarily focused on identifying nerve damage?

Accepted Answer

: An EMG/ NCS reveals abnormal findings due to nerve damage if testing is done at least 4 weeks subsequent to onset, and structural changes to myelin and/ or axon are present.  The test will not be useful if the pain is not due to muscle or nerve dysfunction.

Question 5

what does an emg test show. i had one done for toe pain on both feet and was told pain is from back. how can they know pain is from back?

Accepted Answer

EMG  shows muscle: EMG (electromyography) is a recording of the electrical activity of the muscles (myo) of a specific area.  There is no direct correlation of the electrical muscle activity and the level of pain.

Question 6

repeated cervical & thoracic mris due to neuro symptoms. reported as normal. however recent emg & sseps show chronic denervation & nerve root involvement c3-c5. possible causes of the discrepancy between tests?

Accepted Answer

Method of testing: Imaging studies like MRI just reflect the big picture of the hidden parts of your body while studies analyzing nerve and muscle function like EMG are much more specific to what is exactly happening to these tissues. Microscopic examination of tissue samples (biopsies) is even more specific

Question 7

won't emg to test obturator neuropathy secondary to fascial tethering in sports medicine not work b/c emg only shows severe denervation?

Accepted Answer

Hard to pick up: You are correct that EMG rarely picks up purely sensory problems and most of the time more moderate to severe denervation has to be present to pick this up.

Question 8

left entire body pain for last 6 years (eeg emg mri done, appear normal) but blood test shows dhea levels low, vit d very low and vit b12 borderline?

Accepted Answer

See pain management: Specialist or east-west integrative medicine specialist for evaluation, diagnosis and management. It is a chronic condition that needs thorough examination and investigation.
Take care.

Question 9

symptoms of bad muscle cramping/fatigue/aching all over body brought on by activity that has gotten worse over the years. blood/electrolyte/genetic tests have been normal. emg shows increase insertional activity in 1 muscle. can this mean anything?

Accepted Answer

: Increased insertional activity only has clinical meaning when it is diffused and you only have that finding in one muscle so I doubt its significance.

Question 10

i have l5-s1 herniated disc with year long left calf pain.emg/nerve study result was normal. i took gabapentin for the first time and the calf pain is gone. does it mean my pain is from nerve? if so,how to fix nerve damage that doesn't show on test?

Accepted Answer

: A herniated disc does not necessarily result in nerve issues. The calf pain is not necessarily related to nerve pain from a herniated disc. There are many etiologies of calf pain and gabapentin can help with other types of pain besides nerve pain. It is good that the gabapentin helped with the pain. Good luck to you!
