I didn't feel any after affects other than I did have some muscle twitching for about a week later and a couple tiny bruises.

The same is true of needle EMG for back pain without. Needle EMG for neck pain without arm pain, arm tingling, arm weakness, or arm numbness does not improve outcomes but does increase costs. Usually over in around 30-60mins, maybe a little longer if they test more than one side. Don’t do a needle electromyography (EMG) test for isolated neck or back pain after a motor vehicle accident, as a needle EMG is unlikely to be helpful. These tests can be somewhat uncomfortable, there are worse things, but they are worth it because they can provide valuable info. They give you repeated, brief electrical shocks to the nerve which this little device and check the time it takes for the muscle to contract in response to the electrical pulse is recorded. Nerve conduction testing is also often done at the same time as an EMG. THey are checking the state of the muscle and its innervating nerve. The doctor observes the electrical activity while inserting the electrode. Muscle signals are examined with surface electrodes in sEMG rather than through the traditional needle electrode. Small needles are inserted into select facial muscles and patients are asked to contract those muscles. It is usually employed greater than 6 months following the onset of facial nerve paralysis. THe EMG part is done by inserting tiny needle electrodes through the skin into the muscle tissue at various points they are testing (for example when they test for a pinched nerve in the neck that is causing arm symptoms the needles go in your arm and probably wrist). Electrodiagnostic tests that are painless may also be considered for diagnosing neuromuscular diseases including surface EMG (sEMG), which can complement a nerve conduction study and/or needle examination. Electromyography is a neuroelectrophysiological test that evaluates the health and integrity of the facial nerve. EMGs usually have 2 parts, the EMG (Electromyography) or the NCV (Nerve Conduction Velocity) I think you mean they told you that you are having an EMG to test for a problem in your c-spine ? If not the tests are the same, but the spots they test change.
