How Is A Emg Test Done And Why
I just had an EMG test done and the doctor that performed it first checked my reflex in my ankle and said it was reduced but my EMG was normal. How?
Abnormal reflexes: An EMG measures muscles; reflexes measure nerve activity. Hypothyroidisnm can cause slowed reflexes. Nerve damage at age 20, due to a disease of nerves, such as a neuropathy, is unlikely, but can be checked for by your neurologist. That test is a nerve conduction study (NCS). If NSC is abnormal then you will need more studies to (hopefully) determine the cause. ...Read more
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

I had an EMG test done but during the test the neurologist didn't tell me to flex my muscles could that effect the results?
No: No, you do not have to flex your muscles, just like they contract them. ...Read more
Had an nerve test and emg done on both arms. Nerve on inside of left elbow would not responde to the stimulation. What does that mean and causes?
Pinched nerve: The nerve on the inside of the elbow (ulnar nerve) can get pinched in the elbow as it goes thru a bony groove in that area. Depending on what symptoms were present prior to the test treatment will vary. Severe cases require surgical decompression. Discuss these results with your physician. ...Read more
Besides an emg what other tests can be done to determine what nerve or nerves are being compressed in the elbow my x rays just showed arthritis of the?
Will an EMG test diagnose nerve damage causing cauda equina symptoms or would NCV have to be done too?
EMG/NCV: These tests look at muscle activity and time needed for nerve conduction. Abnormalities usually take several weeks to show up on the test. So if you have had symptoms from compression in caudal equina for quite some time, it may reflect on these studies. (on the other hand 'caudal equine syndrome' is a surgical emergency and needs to be addressed right away. ...Read more
Pinched sciatic nerve. Neg emg test. Vibration sensation in foot. Would cortisone shot relieve vibration and enpingment? Have done pt for 5 months.
Foot pain for past 1.5 years. Foot tingling started couple months ago. EMG & Nerve conduction done results came back normal. How accurate are the test?
Generally accurate.: These tests are generally pretty accurate however this accuracy depends on the equipment and the skill of the person performing the tests. It is important to remember that even though the test results may show the nerves to have normal function, it is entirely possible to still feel pain. ...Read more
I had a midface lift 8 weeks ago. I got buccal or zygomoticbranch injury. Now, my cheek and the corner of the lip have become slightly droopy and I have got a weak smile onthe right side. Should I get an EMG test done for these nerves?
Should resolve: Sorry you are experiencing facial weakness after elective surgery. While there are exceptions to every good rule, facial nerve injuries are rare, and when they happen better than 90% resolve in a few months. It is too soon for an emg, because no matter the results, continued observation is still likely the best treatment. Keep in close contact with your surgeon, and monitor any progress or lack of. ...Read more
25 yo. Diagnosed Peripheral neuropathyUnknown cause. Blood work done. Emg nerve test on legs. Doc said not to worry about it. What should I do now?
Causes of neuropathy:
Include diabetes, toxic exposure (including excessive vitamin B6), thyroid disease, nutritional deficiency, autoimmune disorder, infectious (eg. Lymes disease). etc.
Sometimes its helpful to get a second neurological evaluation to review the NCV, labs and to hopefully identify a treatable condition. ...Read more

How do I treat peripheral neuropathy if I don't know the cause? Emg test and blood work done. Doc isn't concerned. No alcohol diabetes vit d deficient
Not all causes of neuropathy are found. A large number of cases has no apparent cause. Some of these may improve. They are not normally cause for concern.
You can't cure idiopathic neuropathy, but if there are pain symptoms, these can be treated.

I have 4 fingers on my right hand that are paralyzed, tests done, MRI spine, ekg, x-ray, emg, blood-work, neurological exam, MRI brain scheduled?
Carefully: Emg or electromyography is a test done that requires a trained physician (pmr or neuro md) to insert a thin needle electrode into specific muscles to determine whether there is muscle, motor nerve, (or nm junction with special techniques) injury. It can be uncomfortable at times and is usually combined with a ncs (nerve conduction study) test to physiologically examine peripheral nerve and muscle. ...Read more
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 more
Ncv, or nerve conduction velocity, is an electrical diagnostic test that provides information about abnormal conditions in the nerves.

Usually does: They put 2 electrodes on your arm at a known fîxed distance. They then shoot a pulse of elèctricity down the nerve and carefully measure then time. Knowing the precise distance you can calculate the nerve conduction velocity. When you are working on a sensory nerve it can be quite painful. ...Read more
Days at most: There shouldn't be any persistent pain from an EMG other than some muscle soreness (as if you have worked out too hard) that responds to NSAIDs and goes away in a few days at most. There used to be significant concern about bleeding in the muscles, especially those along the vertebrae, but studies have shown a very low rate of these bleeds, even in patients on powerful anticoagulant medication. ...Read more
EMG Pain: Very fine needles are used to perform an EMG or electromyography. Most practitioners will use a type of needle which is covered by a material like teflon with only the tip of the needle exposed. This helps with patient comfort. Also, only a portion of the needle beyond the tip enters the muscle and only transiently. Stretching the skin prior to needle insertion helps. Any pain is temporary. ...Read more
Relax: First you need to show up. Be prepared to sit relatively still for about an hour. The test works best if you relax during it. It is very well tolerated but there may be aspects that are uncomfortable for a very short time. The EMG portion is done with a needle that measures muscle activity. It should not be very painful. Most folks tolerate it well. The results are very useful for your treatment. ...Read more
Perhaps: Some physicians prefer that you hold blood thinners, such as aspirin, coumadin, warfarin, plavix, aggrenox, & others, or if you take Mestinon (pyridostigmine) for myasthenia gravis, you should check with the office several days ahead of your appointment to be certain. Avoid the use of topical creams and lotions on the day of the test. Prescription and otc pain medicines do not affect the test results. ...Read more
Does an EMG or NCV have to be on a specific part or can be done on the whole body to find the problem?
Depends: When evaluating for a systemic disease, the EMG/NCV is often done on nerves and muscles of at least one arm and one leg as well and sometimes the back. Some diseases can be diagnosed with a local study. It depends upon the symptoms and the diagnostic concerns. ...Read more
What to do if I had an emg done & I was questioning what some of the results meant, so what is prolonged latency?
Talk to your doctor: Prolonged latency means one of your responses was delayed. In isolation this abnormality doesn't tell a whole lot. If you still have questions about the results you need to talk to your doctor for additional clarification, as only that type of dialogue would be specific to you and your test ...Read more
I'm not getting relief of pain. Is it common to be negative for an emg test and then be tested a year later as positive? How reliable are these tests?
The quality of an EMG depends upon who is doing it. Can it be negative at one time and positive at another? Yes. The problem could be evolving. However, it depends on the details of "positive".
Pain relief depends on the cause. Also, "not getting relief" over what span of time? Weeks? Years? Makes a big difference. Chronic pain will fail treatment unless the cause is being addressed. ...Read more
