Emg vs muscle biopsy?

Emg vs muscle biopsy?

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 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 an emg diagnose the cause of muscle fasciculations throughout the entire body?

Can an emg diagnose the cause of muscle fasciculations throughout the entire body?

Varies: Muscular fasciculations could be benign, associated with thyroid disorder, or even due to Lou Gehrig's disease. The EMG will assess the physiology, but will not provide final diagnosis as your doctor will need to compile all the data, and correlate. However, at your age, most likely this is benign. ...Read more

What can a muscle nerve and skin biopsy diagnose? There going to do all 3 of them including an emg and ncv

What can a muscle nerve and skin biopsy diagnose? There going to do all 3 of them including an emg and ncv

Lots of things: I'll bet you're getting a polymyositis-dermatomyositis workup. Maybe an amyloid check. But you'd be surprised what they can pick up -- as a pathologist, I've been able to spot the unexpected and help lots of people. Maybe you can get the muscle & nerve biopsies after the others & only if you have no diagnosis yet. Did they run pmdm labs? They're not that accurate but do help. ...Read more

Was told by sister that doctor should have asked me to contract my muscle when performing EMG. Is this true? Because it didn't happen.

Comments: Tough to say if your EMG was done properly or thoroughly, and this test has become a "bone of contention" since Medicare sharply reduced doctor fees, inappropriately. You need to contact the doc who did the study, and ask the specific question you pose, and also, find out what was the outcome. Good luck. ...Read more

Does an emg detect nerve issues or can it detect muscle disorders also? How do the results show on emg? Muscles so weak after small activity n spasms

Does an emg detect nerve issues or can it detect muscle disorders also? How do the results show on emg? Muscles so weak after small activity n spasms

EMG/NCV: The test are combined as EMG and nerve conduction velocity. They often point to possibilities and may not always provide a final diagnosis. They provide insight into defects but not always the cause. Suggest see a neurologist. ...Read more

I have dequ tendons surgery and my muscles tendons and joints repaired they sent me for a emg and nothing so what else coyld it be?

Had critical illness polymyopathy from status asthmaticus...Now emg normal could I have type 2 muscle fiber damage and that's why normal emg?

How do you FEEL?: The best way to tell how well you have recovered from this complicated illness is by how you feel. Since long-term there's no specific treatment and conditioning is important, you are the one to answer the question. And you're right -- a normal EMG does not rule anything in or out. Hope it's a good recovery, best of luck. ...Read more

Can you have a muscle disease...If CPK normal 5 times aldolase normal...Emg and ncv normal. Esr normal....Can you still have a muscle disease?

Why do you ask?: What do you think you have? Myasthenia gravis? Mitochondria myopathy? Mcardle's? Periodic paralysis? Myotonia congenita? Lumping everything together as "muscle disease" and expecting any sort of unifying set of labs / tests is naive. Start with your symptoms / signs and let a competent scientific physician rule the entities in or out until an explanation is found. ...Read more

Dermatomysositis. Wat are the blood tests needed, EMG results wheldl, refused tisue test, &muscle biop. Wat are genetic blood tests, may explain kids sympt

Several things: But first, the muscles break down. Measuring muscle proteins in the blood (CPK, Myosin) will be positive if the disease is active. The pattern of the pain, violet eyelids, sky high muscle enzymes would be pretty diagnostic. Biopsy (which isn't taht bad) would be definitive. EMG (as painful as biopsy) would just show sick muscle. ...Read more

I suffer from elevated ck level from 400 to 1400 as a high. I had a emg, MRI of the muscle, muscle biopsy all normal. Is this heritary?

Can be: There are people who naturally have high ck. The only caution I have is to make sure your muscle biopsy was read by a muscle pathology expert, not only the general pathologist where the biopsy was done. Muscle pathology is a highly specialized area. ...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?

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

Can bfs cause burning type muscle pain? Never been diagnosed with bfs but I have muscle spams all over with normal emg/ncv

Can bfs cause burning type muscle pain? Never been diagnosed with bfs but I have muscle spams all over with normal emg/ncv

Possibly: Bfs can cause muscle aching and, by extension, burning type muscle pains. If you have had an emg/ncv, that suggests that you are already being evaluated by a physician (preferably a neurologist) - be sure to follow through with that evaluation in order to rule out any other possible underlying condition. ...Read more

Which test is better for finding out what muscle twitches are caused by, an EEG or an EMG? Are both really expensive with insurance?

EMG: EEGs are usually for the brain to detect seizures. EMG is used for muscles. I don't know the costs but your doctor can help you and the hospital can give ideas based on your lack of insurance. There are many government programs that can assist you. Good luck. ...Read more

Hydration: Sometimes, an increase of fluids, will help tremendously. Try to hydrate as much as you can before and after exercise and through out the day. Any product that contains h20 with electrolytes will help and of course 2 lts of h20 will go a long way. Try to sleep at least 8 hrs and relax, avoid stress. ...Read more

Emg done on arm wed. He said he got no response from the inside of palm and very little response from muscle right below thumb. Does that mean damage?

Emg done on arm wed. He said he got no response from the inside of palm and very little response from muscle right below thumb. Does that mean damage?

Possible: If there was little response from the muscle in the palm right below the thumb it means that there may be some damage of the median nerve. It is difficult to tell what the diagnosis may be as we don't know the symptoms that prompted the test. An EMG test needs to be interpreted in the context of all the symptoms and nerves examined. ...Read more

My R leg, the muscle on the outside just below the knee is always numb. I am now using a cane to walk to steady me. My EMG come out normal nerves fine?

Get checked: I wonder if you might have a "peroneal neuropathy". Do you have footdrop, where the toe of your right foot keeps dropping causing you to trip or stumble? That's something worth checking out. Hope that helps. ...Read more

Can magnesium levels be normal and still be deficient? I have muscle spasms and twitches but normal emg/ncv normal CPK aldolase as well..

Yes and no: By definition if the levels are normal they should not be deficient. But, it is possible. Also, one should check not only magnesium serum levels but magnesium rbc levels. Still, there are many instances when normal levels are still causing cramping and supplementation helps...... ...Read more

Muscle (Definition)

It is a body tissue that has the ability to contract. It shortens and generates force. It relaxes and returns to its original length. Muscles move joints, stabilize the body, move air and food through the organs, act as valves for bladder, bowel and other organs. They control movement of the eyes. They help us express ourselves by changing the shape of our ...Read more
