If done properly: Likely suffices, but historically, we used to check all 4 extremities. Sounds like, if you have spinal cord compression, the answer to your problems has been achieved. Discuss fully with the doctor who did the EMG ...Read more

Electromyography (Definition)

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

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

If an emg is normal on one side should I ask for the other side?musvle twitching and worried about als.my neuro was fine with just doing the one side.very worried about this!

ALS....: Was the EMG test done in the muscles that were twitching at the time they were twitching? In order to be absolutely certain about the reason for the twitching, you need to see a neurologist. The neurologist will review the EMG study, do a physical exam and decide what, if any, further testing you need to determine the etiology of your twitching. The twitching can be benign, like fatigue.

Had a clean EMG on right side body, but twitching is more active on left. The right side twitches as well, just less. Is this enough to say no ALS?

Had a clean EMG on right side body, but twitching is more active on left. The right side twitches as well, just less. Is this enough to say no ALS?

ALS is not likely: ALS diagnosis is unlikely. 'Twitching' is the least specific symptom and if there are no other symptoms, the diagnosis could not be made at this time . The normal EMG and your age further suggest that this is not likely ALS. If you have symptoms besides the twitching, consulting with a neurologist would be suggested ...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

Had an emg done on one side only. Was worried about muscle twitches.is emg on one side only all you need to rule out ALS ?

No.: The technical criteria for EMG regarding ALS is rather complicated but usually requires multiple muscles in 3 limbs. However, there may have been enough info to rule in another cause of your symptoms. This is where you need to talk to your doc. They may be less concerned with ALS than you are. ...Read more
