How Long Does An Emg Take
30-60 min: Performance of an EMG may include a physician evaluation taking your history and examining you, followed by explanation of the test, completion of the test, and often includes conveying the results to you along with treatment advice. Emg is typically performed alongside nerve conduction studies. A simple one-limb study can take 30-60 minutes. More extensive workups can be as long as 2 hours. ...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 yesterday. I'm in a lot of pain that I have never experienced before with crps. How long will it take to calm down?
No idea: It will vary from patient to patient. ...Read more
Can emg ncs tell the difference between neuropraxia and axonometesis, can it diagnose how long the nerve will take to fully recover?
Yes and no: Yes am EMG /ncs is used to differentiate neuropraxia and axonotmesis but the test itself cannot tell how long a lesion will take to recover. The physician performing the test can give the person an idea of how long an injury will take to heal and whether it is likely to heal based on the test results. ...Read more
I need emg done on 2 legs what are the most painfull part and how long does it take and will it injured anything after im done and what can exspect
Needle exam: The EMG test includes two parts nerve conductions and electromyography. A small electric current is used to test the nerve conduction. The electromyography involves putting a small needle in a sample of the muscles that may be affected to determine if their function is normal. Most people dislike the needle exam as multiple needle punctures are needed. ...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
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

Can taking clonazepam before an emg or EEG test affect results? I only take a 1/4 piece of. 5mg tablet. I only take it as needed.
Relaxants: Anxiety medications can make you more relaxed and can effect the eeg or EMG that you are having. If you only take them as needed don't take them. If you need to make sure the technician doing the study knows so the physician reading the study will be able to interpret it correctly. Hope this helps. ...Read more
How long can swelling near a hematoma last from olecranin bursitis? Been over 30 days, no change. Ortho wants an emg done but I have no insurance.
EMG: An EMG assesses nerve problems. A hematoma and bursitis are not nerve problems. Therefore, an EMG would probably be of little benefit. If the swelling that you speak of is actually the olecranon bursitis, that type of swelling can last indefinitely. Speak to your physician about this to get further guidance about the treatment of the bursitis. You might also consider seeing a pm&r doc as well. ...Read more
Son is having single fiber emg and repetitive nerve stimulation testing tomorrow. Can he take dramamine (dimenhydrinate) prior to leaving our home?
EMG: Usually we don't recommend because they normally have to be awake and functional to follow instructions to make the test more accurate. ...Read more
EMG/NCV report says "H-Reflex at left tibial nerve was 40.15. It was significantly prolonged compared to other leg." Can this cause swelling in leg?
Nerve slow, swell no: Slowing nerve will not cause local, swelling. You should ask if the condition causing the nerve slowing might do this, and ask your doctor. There are multiple causes of swelling, most are benign, but some very serious, and you need correct evaluation to determine which is your cause. ...Read more
Been having twitching all over for 2 weeks. Clean EMG other than twitching in foot. How long should I leave it? Could it be anxiety? What should I do?
It's possible but...: Likely nothing big & it'll stop soon. If you've had an EMG already. (which I think may have been a bit aggressive) but I don't the rest of your case...I'm just sayin'. I've seen so many people going nuts since this ALS bucket challenge that...well, whatever. Have you had some general bloodwork done? That could also complement what you had with the EMG, some electrolytes, thyroids, etc. ...Read more

Direct punch to brachial plexus 3 years ago and misdiagnosed. Specialist just gave BP diagnosis. EMG study neg. Awaiting MRI. How long to fully heal?
Can you give details: If what you're saying is that your brachial plexus injury still has not healed after 3 years then, my feeling is you've reached a state of constancy from which I wouldn't expect much SPONTANEOUS improvement. Key word though is SPONTANTEOUS. There may still be things YOU CAN DO to benefit yourself. Can you give details as to what happened & what the ongoing brachial plexus issues are now? ...Read more

Weak leg n back muscle n loss of leg strength/tingling. Cant walk/stand for long. Is this sciatica? EMG normal. Have history of B12/D def. Now b12 is 250
Possibly: An emg/ncv test is not 100 percent sensitive for sciatica, so it could possibly be coming from the irritation of a nerve in the back causing symptoms in the leg ("sciatica"), but there are other potential causes as well. An MRI of the lumbar spine would show if there is any nerve impingement that correlates with your symptoms. Continue being seen for further work up. ...Read more
If you have numbness and tingling in the hand does it come from your neck? Does the doctor perform a EMG? Please help what kind of exam takes place?
Hold your horses: The first "exam" that needs to be done is a history and physical by a clinician in the office. Don't be so ready to second-guess the process. Would you do that with your lawyer or mechanic or plumber? ...Read more

I was in MVA. MRI shows Rotator cuff tear, labra tear and tendinitis on shoulder. EMG shows pinched nerve. Will Physical Therapy help and how long?
Can't answer w/o inf: The space here is limited to provide a good answer to your question. You should speak to an Orthopedic Surgeon or sports medicine doctor (rehab?) to answer this question. Generally, rest, ice, & compression is used to help support healing. Anti-inflammatories like Tylenol (acetaminophen) could be used also. Later on, rehab is used when healing has started but timing is up to the surgeon. ...Read more

Can a neck strain last longer than ten months? I've had it since june of 2013 with some trouble swallowing, twitching and cramping. Is this normal? Wanted an emg which came back negative. Please help.
Nerve impingement: Is a very common problem, affecting about 10-12% percent of the adult population in the us. Nerve impingement can be caused by being sandwiched between two spinal bones, pressed by a bulging disc or encroached upon by bony overgrowth. Rec.: see an interventional pain management specialist for further investigation. ...Read more
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
