Discomfort During The Procedure

Patient Testimonial of EMG Test for Neck & Shoulder Pain – Allcare Physical Therapy in Brooklyn, NY

While there is little or no sensation involved with the detecting of electrical activity, the insertion of the needle itself into the muscle may cause discomfort but generally not more so than if you were receiving a shot or giving blood. The neurologist only performs one insertion at a time, and you receive advance warning and guidance for minimizing the discomfort while its happening. Depending on the muscle and extent of testing, the neurologist may need to perform several insertions over a period of time.

I canceled my EMG appointment because I was chicken. They called me to reschedule and Im on the fence here. So veterans. How bad is it?Ive had a nerve conduction study and that was tolerable. Thank you for sharing your experience/thoughts.

This is too funny because I have had both an EMG and NCS over 2 and a half years ago and it wasn’t awful, yet not pleasant. The needles in muscles are a little tough. Now here I am after the fact with a diagnosis of SFPN and more pain, and going for 2nd round of testing to rule out further advancements. Ughhcontemplation. I’m between do I or dont I? Scheduled for July 10th with a 2nd neurologist opinion the 14th. I’m feeling ckickenish too but, am going to make it happen. I hope you will too if it means possibly helping you or bringing clarity to your situation. Best of luck! We got this.Rachel

You/re going there for a reason, that’s what you should keep in mind.Tell them you have anxiety for this procedure and they may prescribe one anxiety pill for you for that appointment as long as you bring a driver with you. I had it done, it’s not so bad .

I had an EMG several years ago. Mine was not for neuropathy. It’s a valuable tool for your Dr. to be able to proceed with your treatment. Sometimes we have to go through difficult part to get to the answer. Don’t be uptight. Just relax. The tech will guide you through it. I am facing one in July for neuropathy.

Are There Any Reasons I Should Not Have An Edx Study

If you are on blood thinning medications, such as aspirin, plavix, heparin or warfarin , the physician may not perform certain portions of the test. If that information is absolutely necessary, you may be asked to stop blood thinning medication prior to the electrodiagnostic test. If you have a pacemaker or similar device, certain portions of the test may not be able to performed.

How Painful Is An Emg Test

discomfortEMGsore

Just so, how long does an EMG test take?

30 to 90 minutes

Also, how long does pain from EMG last? After an EMG, you may be sore and have a tingling feeling in your muscles for up to 2 days. You may have small bruises or swelling at the needle site.

Also, what is an EMG test used to diagnose?

An EMGelectromyogramis a test that checks the health of nerves and muscles. An EMG involves inserting tiny needles into your muscles to record electrical activity. Your doctor may recommend this nerve conduction study to help diagnose nerve and muscle diseases and seizures.

Why was my EMG so painful?

Pain is commonly associated with EMG, because the procedure involves the use of needles and electric shock. We hypothesized that expected VAS levels would be higher than experienced VAS levels in response to nerve conduction studies and needle EMG.

How Do I Get Ready For The Tests

EMG/NCV

You donât need to do anything special before either test. Doctors do recommend that on the morning of a test, you:

  • Bathe or shower, but donât put on any lotions or moisturizers
  • Avoid caffeine and sugary beverages for at least 2 or 3 hours before a test
  • Donât smoke before a test

You should also talk with your doctor about taking medications before a test. There may be certain medicines you should avoid taking until after the test.

If you have a pacemaker, you should tell your doctor before they schedule NCS or EMG.

Emg And Ncv: Discomfort And Risks

  • EMG: You may feel discomfort when the needle electrodes are inserted.
  • NCV: You may feel startled when the electrical pulses are generated.
  • After EMG: The muscle tested may feel sore, and you may have minor bleeding or bruising where the needle electrodes were inserted.
  • EMG risk: Small risk of infection where the needle electrodes were inserted.

About Spinal Diagnostics: Nerve Conduction Studies

A nerve conduction study is usually done along with electromyography . The nerve conduction study stimulates specific nerves and records their ability to send the impulse to the muscle. The study can show where there is a blockage of the nerve pathway.Nerve conduction studies are done to:

  • Find and evaluate damage to all the nerves that lead away from the brain and spinal cord to the smaller nerves that branch out from them
  • Help diagnose nerve disorders, such as carpal tunnel syndrome or Guillain-Barré syndrome
  • Find the location of abnormal sensations, such as numbness, tingling or pain

What To Expect During A Nerve Conduction Study

Have you been experiencing numbness, tingling, or continuous pain with no known cause? If so, your neurologist may recommend having a nerve conduction study performed. A nerve conduction study, also known as nerve conduction velocity test measures the speed of electrical impulses as they move through the nerves. Based on the results, your neurologist can determine if nerve damage has occurred, where it has occurred, and to what extent.

Oftentimes, nerve conduction studies are performed in coordination with an electromyography , which is a test that measures electrical signals produced by the muscles when they are at rest versus when they are active. Conducting these two diagnostic tests allows your neurologist to more accurately determine if the cause of the problem is a nerve disorder or if it has affected the muscles. In some cases, both the nerves and muscles can be affected.

Nerve conduction studies and EMGs can diagnose a variety of conditions, including:

  • Amyotrophic lateral sclerosis aka: Lou Gehrigs disease
  • Carpal tunnel syndrome
  • Peripheral nerve injury
  • Sciatic nerve problems

The day of your appointment, you will be asked to remove any metal objects you may be wearing to prevent interference. Depending on the location of the area being tested, you may also be asked to change into a medical gown. The location of the area being tested will also determine if you are sitting or laying down during the test.

What Are They Testing For

EMG testing is done to investigate the health of your nerves and muscles. There are a large number of different nerve problems which can be tested for, so we cannot be more specific here. Your referring physician is best qualified to answer any specific questions you have regarding the reason for your referral.

Will I Need To Do Anything To Prepare For These Tests

Tell your health care provider if you have a pacemaker or cardiac defibrillator. Special steps will need to be taken before the test if you have one of these devices.

Wear loose, comfortable clothing that allows easy access to the test area or can be easily removed if you need to change into a hospital gown.

Make sure your skin is clean. Don’t use lotions, creams, or perfumes for a day or two before the test.

How Are Nerve Conduction Studies Used To Diagnose Neuropathy

Electromyography and nerve conduction studies for Neuropathy Diagnosis. You will be asked to relax the muscle and then contract the muscle after the needle is inserted. The needle is connected to a computer that helps the doctor determine whether your muscle is healthy or affected by a disease of the muscle or nerve.

Symptoms Of A Pinched Nerve

How Does EMG Testing Evaluate Nerve Damage?

A pinched nerve refers to a nerve under significant pressure from surrounding tissue, disrupting the ability of the nerve to function properly.

A pinched nerve can happen in any part of your body. But pinched nerves in the back or shoulders are likely to cause chronic pain. Its possible to overdo an activity and feel temporary pain, but pinched nerves should be considered if the pain is frequent or becomes chronic.

The symptoms of a pinched nerve include:

  • Pain
  • Numbness or tingling
  • Muscle soreness

If youre experiencing any of these symptoms, we can help determine whether youre suffering with a pinched nerve.

Carefully Weigh The Cost To Patient In Time Money And Possible Pain Against Diagnostic Benefits Before Referring For An Emg

Shivkumar C. Bhadola and Kate M. Daniello, MD

Nerve conduction and EMG studies are an important procedure for evaluating possible peripheral nervous system disorders. EMG can be considered an extension of the clinical neurologic examination, rather than simply a test, and is ordered by many healthcare providers from all specialties. Choosing which patients to refer for EMG is important because there are costs of patient time, money, and perhaps most importantly, pain intrinsically associated with EMG itself.1 This review addresses the types of patients and pain that warrant referral to EMG and when to consider this a useful diagnostic study.

Can My Spouse/child/relative Come In To The Exam Room With Me

If you are accompanied by a family member, the family member can usually be in the room with you during testing, providing that you approve of this. For reasons of patient privacy and confidentiality, relatives and friends may not accompany you during the test if you do not wish them to. Your privacy is our priority.

An Emg Test Can Actually Hurt

It depends on how sensitive a person is to pain, and in the case of an EMG test, the pain can come from two sources: an electric shock delivered by the doctor, and needle pricks, which can take the form of an embedded needle that the doctor maneuvers around while its beneath the skin.

I sat in on my mothers EMG test for her suspected pronator teres syndrome.

The doctor had warned her the day before, It will be unpleasant. The needles are a little thicker than acupuncture needles, said the doctor.

An electric shock is always an unpleasant experience, and there will be times that the doctor will increase the voltage.

I was watching my mothers face while he applied the shock with a cell-phone-sized device that hed press a button on for a split second.

She was lying on her back, eyes closed, while he worked on her arms. Her eyes would mildly flinch, and sometimes flinched more noticeably. Sometimes her face twitched from the discomfort.

However, in my mothers case, most of the hurt from the EMG came from the needles.

The doctor would place a needle on her skin, then tap the top of it. At one point he embedded a needle about a quarter inch into her skin on the underside of the palm, and moved it around.

The most painful needle prick was when it was applied to my mothers left palm, even though the doctor had tested her right palm first. She let out a good yalp when this happened.

Id imagine that if they were concentrated on the upper legs, they wouldnt hurt as bad.

What Are Electromyography And Nerve Conduction Studies

EMG – How to Test for Pinched Nerves

Electromyography and nerve conduction studies are tests that measure the electrical activity of muscles and nerves. Nerves send out electrical signals to make your muscles react in certain ways. As your muscles react, they give off these signals, which can then be measured.

  • An EMG test looks at the electrical signals your muscles make when they are at rest and when they are being used.
  • A nerve conduction study measures how fast and how well the body’s electrical signals travel down your nerves.

EMG tests and nerve conduction studies can both help find out if you have a disorder of your muscles, nerves, or both. These tests can be done separately, but they are usually done at the same time.

Other names: electrodiagnostic study, EMG test, electromyogram, NCS, nerve conduction velocity, NCV

What Can An Emg Detect

Electromyography, often referred to as an EMG, is a diagnostic tool used to detect neuromuscular problems that cause pain, tingling, weakness, and spasms. If you experience these issues, your doctor will likely request an EMG to get a clearer picture of what could be causing your symptoms.

The results of an EMG can provide useful information about the health of your motor neurons and muscle function. An EMG can detect movement problems, nerve compression, nerve injuries, and muscle degeneration.

Will There Be Needles

Some of our tests do involve using a very small needle. This needle is placed gently into specific muscle groups, depending on the problem we are investigating. It is important to note that not all of our studies require needle EMG. Whether or not you will need needle EMG depends on what your doctor has asked us to investigate. The needle used in our test is probably the smallest needle you will ever get.

The needle acts like a microphone and picks up the electrical activity in your muscle, which can then be evaluated to see if there are any abnormalities. Our needles, in addition to being very small, do not inject anything, nor do they take any samples from your muscles, they just “listen” to your muscle.

What Do The Results Mean

On

If your results were not normal, it can indicate a variety of different conditions. Depending on which muscles or nerves are affected, it may mean one of the following:

  • Carpal tunnel syndrome, a condition that affects nerves in the hand and arm. It’s usually not serious, but can be painful.
  • Herniated disc, a condition that happens when a part of your spine, called a disc, is damaged. This puts pressure on the spine, causing pain and numbness
  • , an autoimmune disorder that affects the nerves. It can lead to numbness, tingling, and paralysis. Most people recover from the disorder after treatment
  • Myasthenia gravis, a rare disorder that causes muscle fatigue and weakness.
  • Muscular dystrophy, an inherited disease that seriously affects muscle structure and function.
  • Charcot-Marie-Tooth disease, an inherited disorder that causes nerve damage, mostly in the arms and legs.
  • Amyotrophic lateral sclerosis , also known as Lou Gehrig’s disease. This is a progressive, ultimately fatal, disorder that attacks nerve cells in your brain and spinal cord. It affects all the muscles you use to move, speak, eat, and breathe.

If you have questions about your results, talk to your health care provider.

How An Emg Works

The motor neurons in your body produce electrical signals, and the muscles contract in response. An EMG will be able to detect your bodys neuromuscular response to stimulation. During the test, you will be asked to contract your muscles through certain movements.

An EMG may be done by inserting tiny electrodes through your skin into the muscle. These electrodes will then provide information to an oscilloscope, which records your neuromuscular electrical activity as waves, graphs, or sounds on the monitor.

An EMG can also be performed using electrodes, which are stickers that are placed on the surface of the skin. This will measure the speed at which your muscles respond to the electrical signals from the motor neurons.

Will An Emg Show A Pinched Nerve

    Living with chronic pain can bring anyone to their wits end. While its normal to experience a little muscle soreness every now and then, normal muscle soreness generally goes away after a couple of days. Sometimes, what you think is muscle soreness is actually a pinched nerve.

    If you notice that your muscle soreness isnt going away, its time for further investigation.

    At his practice with locations in Wilmington, Delaware, and the Philadelphia area, Dr. Steven Grossinger is a pain management expert who performs diagnostic tests, including EMG, to determine the root cause of your pain.

    In this blog, Dr. Grossinger discusses pinched nerves and how an EMG can be a useful diagnostic test.

    Nerve Conduction Velocity Test

    A nerve conduction velocity test is an electrical test that is used to determine the adequacy of the conduction of the nerve impulse as it courses down a nerve. This test is used to detect signs of nerve injury.

    In this test, the nerve is electrically stimulated, and the electrical impulse ‘down stream’ from the stimulus is measured.

    Yes. There is some discomfort at the time the needle electrodes are inserted. They feel like shots , although nothing is injected during an EMG. Afterwards, the muscle may feel a little sore for up to a few days.
