Electromyography: Emg and ncv testing is used to help diagnose nerve and muscle problems. Examples include spinal nerve impingement (from herniated disc), carpel tunnel syndrome, ulnar syndrome, sources of radiating pain. Pain, numbness, weakness, muscle fatigue are some of the reasons that you may need an emg/ncv test. ...Read moreSee 1 more doctor answer
Emg (electromyography) is a test of your muscles and nerves. It is typically performed along with nerve conduction studies (ncs). The EMG portion involves placing a recording pin (like a fine wire antenna) into various muscles, looking for 'muscle distress signals' that could suggest nerve or muscle diseases/problems. Nerve conduction studies involve stimulating nerves ...Read more
See below: The EMG portion uses a small needle to directly examine muscle function, and the nerve conduction part uses electrical shocks to measure nerve function. Together the study gives a good idea of the nature of the pathology and location, but can also assess the prognosis and character, and gives often guidance towards an eventual diagnosis. ...Read moreSee 1 more doctor answer
Tolerable discomfort: Emg and nerve conduction studies are typically performed together. Nerve conduction studies feel like a short electrical impulse and are, in a word, annoying. Several nerves are tested. Emg involves placing a fine wire pin into various muscles-- the pin is about the size of an acupuncture needle and feels like an insect bite-- not as bad as a shot, iv, or blood draw. Several muscles are tested. ...Read moreSee 1 more doctor answer
See different things: Both tests are useful, but they serve different purposes. Emg is a functional test that allows for the assessment of muscle irritability, as well as signs of nerve damage. It is fast, minimally invasive, and can be performed on multiple muscles in a single session. Biopsy is an anatomical test that is more invasive, but provides a deeper look at muscle structure. ...Read moreSee 2 more doctor answers
Maybe uncomfortable: Most patient's tell me it was not as painful as anticipated. The ncs involves electrical stimulation of the nerves, the EMG involves inserting a very small needle into several mucles. I think most patients describe the test as uncomfortable not painful. ...Read moreSee 1 more doctor answer
Nerves & muscles: Emg and nerve conduction studies are used to detect abnormalities of nerves and muscles. The test evaluates nerve roots as they exit your spine, the nerve plexus, peripheral nerves, the nerve-muscle junction, and muscle itself. It can detect pinched/compressed nerves (sciatica, carpal tunnel, and others), muscle disorders, neuropathy, and many other neuromuscular conditions. ...Read moreSee 1 more doctor answer
Test nerve function: They are a way to test the function of nerves in the body, looking for focal (like carpal tunnel) or generalized (like diabetic neuropathy) problems. They are performed by stimulating the nerve electrically (which feels like touching a doorknob after shuffling your feet on a carpet on a dry day), and recording the response. They are uncomfortable, but very helpful in clarifying a diagnosis. ...Read moreSee 1 more doctor answer
Nerve ; muscle test: Emg/ncs is a test that uses small electric shocks along nerve tracts, and needles into muscles.. While small nerve fibers cannot be accurately tested, middle and large nerves will demonstrate changes in transmission times and rhythm. Muscle, will demonstrate changes in wave form, and resting potential. Neuropathy, polio, myopathy, radiculopathy, entrapped nerves, carpal, cubital/ carpal tunnel, . ...Read moreSee 1 more doctor answer
No: Though there are limitations on what a nerve conductions test can show. If it shows something (and is done by a knowledgeable physician), it is definitely there. It may not be sensitive enough to pick up subtle changes. Not every nerve condition is detectable by this test. If done too soon after an injury (less than 3 weeks), may not show up. If symptoms are worsening, it is worth retesting. ...Read more
Could taking lyrica (pregabalin) affect the results of an mr neurography study?
Brachial plexus neuropathy...
Good Question: This is a great question. I have not been able to find any research suggesting that Lyrica (pregabalin) could affect the results of an mr neurogram. Mr neurograms are relatively new, so i'm sure more information on this will become available soon. ...Read moreSee 1 more doctor answer
I'm having nerve conduction tests for carpal tunnel. Couldl the same test show guyons tunnel syndrome?
Possibly: Depends on how detailed the neurologist or other physician is in performing the emg/ncv's. If your referring physician explains the need for testing the ulnar nerve in guyon's canal it can be done... In my experience most ' routine' EMG 's of the upper extremity will note conduction 'slowing' @ the elbow( cubital tunnel) but not @ the wrist... Best of luck! ...Read more
Yes to your question: Damage to any nerve that supplies a muscle may cause twitching. When the ulnar nerve is damaged, twitching may occur along the medial forearm, and many muscles that move the fingers - such as the muscles that move the fingers apart and together and the muscles that help the fingers curl and grip. http://www.neurocuro.com/peripheral-nerve-entrapment/ ...Read moreSee 1 more doctor answer
Very Hard: I would suggest if you can't figure it out, you speak with the doctor that either ordered it or the doctor that performed it. Ask them to speak in lay terms with you. Otherwise unless you have prior medical background it will be another language for sure. ...Read more
Yes, neurologist: An orthopaedic surgeon can diagnose carpal tunnel syndrome(cts). Those patients with numbness/tingling in the thumb, index, long and 1/2 of the ring fingers and night pain don't usually need a conduction study. However, if there is any question about the diagnosis, an emg/ncv study can be performed by a neurologist of physiatrist. A board certified orthopaedic hand surgeon can provide treatment. ...Read moreSee 2 more doctor answers
