Normal Emg Ulnar
Can be: Uncomfortable, but not particularly painful, but that should not be a reason not to undergo the test if your doctor feels it to be necessary. The person performing will be able to tell you exactly what to expect. ...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
My neurologist did a ncs and emg, and found: "severe ulnar entrapment at multiple levels". Could you, please, explain this diagnosis for me?
The ulnar nerve is a nerve that helps control the lower arm. It controls muscles that help clench the fist, flex the wrists and fingers. It gives sensation to the inner portion of the forearm and the ring and pinky fingers.
Although usually injured at the inside of the elbow (the 'funny bone'), your nerve has more than one site of injury. I would discuss this with your doctor to learn more. ...Read more
Negative EMG — Diagnosed with Ulnar Neuropathy. Is surgery still beneficial as a preventative measure (to avoid muscle wasting) at this stage?
It depends : If the ulnar neuropathy was demonstrated from an imaging study showing a compression or other specific cause surgery might be beneficial but the lack of correlation to the EMG/NCV is bothersome. Discuss further with your doctor about the benefits of surgery and the current diagnosis before proceeding would be a suggestion. ...Read more
32 yr female w5 yr ulnar wrist pain. No motor loss. Burns/aches/numb. Painful to type, apply makeup, write. Xray, ncv, emg negative. Pain on pisotriquetral joint. Ulnar/median decompression. No mri. What's wrong?
Wrist pain: Without a mri- it sounds like wrist tendonitis with or without compression neuritis. I would consult an orhtopedic surgeon. Sometimes an injection of xylocaine (lidocaine) with a steroid will alleviate the pain. Also, i always suggest the use of a pull on, neoprene tubular wrist support worn over a terry tennis wrist towel: it will really help. ...Read more
Nothing: Electromyogram and nerve conduction studies identify where nerves have been damaged and/or are undergoing repair. Unfortunately, these studies cannot detect sites of chronic pinching (impingement), which is painful but does not alter neural tissue nor cause positive study data. These tests cannot rule out chronic impingement, which is common. See my board on quora. Com about this medical issue. ...Read more
Had slightly abnormal NCV accompanied by completely normal EMG. What (if anything) could this mean.
Ask neurologist : The neurologist who read the EMG NCV study should explain the interpretation of these findings to you ...Read more
A normal emg/ncv in march 2013 and a normal emg/ncv in august 2013 would rule out what? What does an emg/ncv rule out if normal?
Interpretation: Assuming the test was comprehensive and technically competent, this can eliminate large fiber neuropathy, and most muscle diseases. But does not eliminate small fibre neuropathy, or disease of brain and/or spinal cord. Symptoms due to intermittent nerve compression are not fully excluded either. ...Read more
Can vary: If disease is localized to brainstem solely, EMG may be negative early on, as location of damage to motor neurons can vary from case to case. And pace of progressive damage can also vary. ...Read more
Yes: Yes, it depends on where the problem is, how long since the injury or disease process started and what is being tested on the NCS/EMG ...Read more
If fasciculations appear 2-3 weeks after normal emg, should emg be repeated or is it still valid?
No needs: Results Still valid. No needs to repeat. Be well. ...Read more
Hi, in emg tests is it possible for fine movements to be abnormal and larger ones to be normal at the same site? Poss to have fine movement prob only?
LIttle confusing: Emg testing is specific to the nerve muscle connection. Emg is also a broad term that may also include ncs or nerve conduction testing as well. The ncs looks at the function of large fiber nerves which can be normal if the main source of a nerve problem is the small fiber nerves. Small fiber nerves can be evaluated with a small biopsy. Discuss with the doc who did the test. ...Read more
Would be unlikely: If motor neuron disease exists, and could be in form of primary lateral sclerosis, there will usually be some degree of EMG pathology. A fully normal EMG would tend to rule against a diagnosis of any kind of motor neuron disease, but early on, findings might be very minimal and the test might need repetition in several months. ...Read more
CIDP: Yes, in some cases electrophysiological studies fail to show any evidence of demyelination. Though conventional electrophysiological diagnostic criteria are not met, the patient may still respond to immunomodulatory treatments. In such cases, presence of clinical characteristics suggestive of cidp are critical, justifying full investigations, including sural nerve biopsy. ...Read more
Took 5g Flagyl over 6 months for repeated diverticulitis, emg now shows slow nerve velocity where previous emg normal-- coincidence?
Normal emg but paraspinal abnorm insert increase and fib-3. Tid anterior normal but with muap duration-1/few poly muaps. Possible reasoning?
PARTIAL INFORMATION: You are expecting us to correlate without any background information, but I'll comment. If you had prior surgery, or spinal cord tumor, the paraspinals will be abnormal, and the limb findings may represent nerve root compromise. If you wish to delve into this further, schedule concierge visit. ...Read more
I feel that my leg is vibrating, like cell phone is vibrating inside my leg.I did a leg EMG 4 months ago and it was normal.what should I do?
Sometimes you can get an irritated nerve in the leg, this will present with numbness, tingling, vibration, cold sensation or other variations of this.
If the EMG is normal that's a good start. The nerve could be irritated anywhere from the spine down to the leg itself. Start with good lower back and leg exercises. Try TENS unit.
If it continues or you notice weakness or numbness then back MRI. ...Read more
What could've caused my false + (12% decrement) repetitive nerve stimulation test? 2 subsequent RNS and SF EMG are normal so it was definite false +
False positives: False positives are by definition variations of normal. Our body functions fluctuate from day to day. Normal ranges only capture 95% of asymptomatic people. The other cause for false positives is equipment error. Simple chance will result in false positives if enough tests are done. Sounds like it's time to stop getting these tests. ...Read more
Emg tests are normal but rheumy thinks I have sfn. Neuro won't do biopsy since my meds would be the same. Really want to know. Should I get the biopsy?
Let me explain:
In medicine the best to do to reach a diagnosis. I do understand you doctor is reluctant to do the biopsy because the treatment is the same.
If feel strongly about the biopsy, I will seek second opinion. ...Read more
My emg came back normal and said negative for neuropathy. Does that mean I have a greater chance of really having crps? Worried! Help...
Symptoms: Can you provide us with some symptoms and what was found on physical examination? ...Read more
Normal emg & bfs diagnosis. Is there a way to stop or at least alleviate these twitches permanently? What is the effect of regular exercise? (m, 30)
What could cause numbness and loss of force? My last EMG showed muscular recruitment at 50%, the rest of the test is normal, and also the other tests
Sensory motor neurop: It sounds like you have a sensory motor neuropathy. I do not buy that your nerve conduction 0 otherwise normal. The problem with EMG test, like eg is that it is very subjective. Some doctors are just too conservative, and tend to under retest. Some just don't know how to read him at all. I would get a second opinion. ...Read more
No.: No.Get a more detailed answer ›
Yes: Only god is perfect. All tests have false negative and false positive results. Clinical symptoms and your signs are worth more than a test. ...Read more
Should suffice: If your neurological exam proves to be fully normal, and you have appropriate strength and reflexes, would not feel need to do EMG study, as yield would be infinitesimal. ...Read more
Lower EMG/NCS came back normal. What else could mimic the Sciatica/sciatic. What is the difference in the two? I'm still having issues.
I have numbness in my left middle fingertip, and I have pain in my left arm. Emg test are normal, I wanted to know what ese can be the problem?
How long have you had the numbness. Did you have both an EMG and nerve conduction studies. When was the EMG and nerve conduction studies completed in relation to onset of symptoms. Do you have the actual results of the EMG with you or just "it was normal?"
In certain situations, if the EMG and nerve conduction studies are done too soon, they will come back normal. ...Read more
