Human nerves are located throughout the whole body. Have you ever wondered exactly how they transmit signs that allow you to feel, think, and react to the world around you? Nerve conduction studies penetrate deeply into this complex system. They reveal the secrets and role of nerves in preserving human health.

Nerve conduction is a unique characteristic of the nervous system. It describes the speed at which impulses are carried through nerve fibers. Nerve conduction depends on many factors. It includes the general condition of the body, the presence of diseases, age, and so on.

The health of your nervous system is an essential factor in your overall well-being. Stress, lack of sleep, illness, and injury can all affect your nerves. It can lead to various problems. What can you do to support nervous health? Understanding NCV testing and its function can help you realize how a healthy lifestyle can positively affect your health.

What Are Nerve Conduction Studies?

The human body is a complex system. And the nervous system plays a crucial role in it. For this reason, neurologists conduct various studies on it. After all, any failure in nerves can lead to fatal consequences. So, one of the most common conductions is NCV testing.

It is an important aspect of medical science. It allows you to study and understand the work of the nervous system. This process involves analyzing the transmission of electrical signals along nerve fibers. It evaluates their parameters. So, with it, medical professionals can detect various pathologies in the nervous system. This procedure may be helpful in the diagnosis of diabetic neuropathy. It is one of the diseases that disrupt nerve conduction.

One of the main methods of studying nerve conduction is electromyography (EMG). This continuous process allows the recording of the electrical activity of muscles and nerve fibers.

And another critical method is electroencephalography (EEG). It allows recording of the electrical activity of the brain. It is a helpful tool in detecting epileptic zones and diagnosing neurological ailments.

So, nerve conduction tests are a big step forward on the way to a healthy life. With the help of this, you can protect yourself from the progression of some conditions. After all, this makes it possible to detect them in the early stages.

How Do Nerve Conduction Studies Work?

During the procedure, doctors place electrodes near the muscles. That is, in those places that you need to explore. These electrodes stimulate the muscles and record the responses of nerve signals. At the same time, they register the details of the passage of the motion. It goes through the nerves and muscle reactions.

When a motor nerve is stimulated, the doctor assesses how the muscle it controls reacts. If they activate a sensory nerve, they note a response further along the nerve. Thus, measuring the time of impulse transmission along nerve fibers makes it possible to find out the results of this examination.

The Significance of Nerve Conduction Studies  

Any research in the medical field is of great importance. It also includes electroneurography. Neurologists greatly appreciate this method of health research. After all, it can say many things about the state of your central nervous system. So, keep a few points that highlight the importance of this examination:

  • It can detect interferences in the transmission of signals between nerve cells. It can help detect pathologies. These can include peripheral neuropathy and sclerosis.
  • It helps doctors make an accurate diagnosis. If you experience specific symptoms for which you can not find a cause, NCV testing can help determine the problem. Based on the results, doctors decide the optimal treatment plan for patients. With the help of these data, you can choose effective physiotherapeutic procedures.
  • It helps watch the disease’s progression and take appropriate corrective measures.

The nerve conduction research is safe and uncomplicated. It is an important factor in effective diagnosis and treatment of nerves.

Benefits and Limitations of Nerve Conduction Studies

Such nerve tests are essential. But like any method of diagnosis and treatment, they have advantages and limitations. So let’s analyze them in more detail:


  • Accuracy of information. Research makes it possible to get very accurate info about the state of the nervous system.
  • Painlessness. This diagnostic method is practically painless and non-invasive. It makes it safe for patients of all ages.
  • Patient education. It can give patients and their close ones important information about their nerves. That is, it helps them learn how to manage their health.
  • Determining the effectiveness of treatment. It also makes it possible to assess the efficacy of treatment. The study may reveal the restoration of the functions of the nervous system.
  • Differential diagnosis. Such a study helps to distinguish compression injuries of nerves from degenerative diseases.


  • Difficulty in reading the results. Sometimes nerve conduction results can be challenging to interpret by medical professionals.
  • High cost. It can be expensive. It makes research less accessible to patients with disabilities or low incomes.
  • Equipment requirements. Special equipment is necessary for the procedure. It can be expensive and need a certain level of qualification in medicine.
  • Influence of external factors. The patient’s emotional state, body temperature, and other external factors can affect the nerve conduction test results.
  • Medical experience. The study’s results may depend on the experience and qualifications of the operator. Incorrect placement of the electrodes can lead to inaccurate results.

Common Conditions Diagnosed with Nerve Conduction Studies

Do you want to know if everything is fine with your health? Are you preparing for the electroneurography procedure? You need to familiarize yourself with which illnesses this testing can determine. So, the common diseases diagnosed with this examination are:

It can significantly limit movement and cause pain. This disease can occur in any part of the body. But most often, it is present in the wrist and elbow.

  • Polyneuropathy

It can lead to various symptoms. Among them are weakness, numbness, tingling, and pain. It affects both sensory and motor functions. 

  • Myasthenic syndrome

It is a disease that affects the muscles and can lead to losing control over movements.

It is one of the most common complications of diabetes. It affects the peripheral nerves. So, it can lead to loss of sensitivity, muscle weakness, and pain in the lower extremities.

Nerve conduction studies can detect this kind of infection. Of course, there are other options besides them. But these are among the most common.

Procedure and Preparation before Nerve Conduction Studies

Nerve Conduction Studies: Procedure and Preparation

This procedure is simple. But it requires some preparation from the patient and the doctor. The study includes stages that provide detailed answers about the state of the nervous system:

  • Preparation

Before starting the procedure, the doctor explains all study aspects to the patient. After that, the patient needs to remove all metal jewelry. It is so that it does not interfere during the NCV testing.

  • Placement of electrodes

Medical personnel place special electrodes on the skin. They are placed near the investigated nerve. And doctors usually conduct test stimulations to check their correct location.

  • Stimulation and registration of signals

Next, the specialist stimulates the investigated nerve with small electric currents. 

  • Completion of the procedure

At the end of the study, the specialist will remove the electrodes. Then the patient can return to normal activities without restrictions.

In general, it is a painless and safe procedure. If you need it, be sure to follow the guidelines for more accurate results.


Do you feel that something is wrong with your health? Are certain of your symptoms indicating neurological disease? It’s advisable to see a neurologist for you. In such cases, they will assign you NVC testing. It is what can identify hidden conditions in you and prevent their progression.

Don’t you know which specialist to contact? Lone Star Neurologists can be your best destination. Based on our experience, we will conduct all the necessary research for you. It will help determine specific preventive measures for you.


How long does a nerve conduction study take?

The time needed for a nerve conduction study can differ. On average, it takes approximately 60 minutes. It is to complete the examination and gather accurate results.

What conditions can be diagnosed using nerve conduction studies?

Nerve conduction studies play a crucial role in diagnosing MS. It is a chronic autoimmune disease that affects the central nervous system. Also, NCV testing can detect brachial plexus injuries and ulnar neuropathy.

Are Nerve Conduction Studies Painful?

Most patients report that nerve conduction studies are not painful at all. But you can feel a bit of unusual pain due to the electrical impulses used during the test. The sensation is often felt as a quick zap. It lasts only for a fraction of a second.

Can a nerve conduction test damage nerves?

No. The test involves the application of small electrical impulses. They stimulate the nerves and measure their response. But these impulses are carefully controlled and within safe limits.

Just such an amazing staff that makes you feel like part of their family. I’ve been going there for over 5 years now... and each visit I get the very best care and treatments that I have ever received in the 20+ years that I’ve been dealing with severe debilitating migraines. Since i started seeing them the number of my migraines has dropped from 15-20 a month to 2-3 every 3 month. I highly recommend them …they will change your life!read more

Dr. Askari was very kind and explained everything so I could understand. The other staff were nice as well. I would... have gave 5 stars but I was a little taken aback when I checked in and had to pay 600.00 upfront. I think that should have been discussed in a appointment confirmation call or email just so I could have been more

I was obviously stressed, needing to see a neurologist. The staff was so patient and Dr. Ansari was so kind. At one... point he told me to relax, we have time, when I was relaying my history of my condition. That helped ease my stress. I have seen 3 other neurologists and he was the only one who performed any assessment tests on my cognitive and physical skills. At one point I couldn't complete two assessments and got upset and cried. I was told, it's OK. That's why you're here. I was truly impressed, and super pleased with the whole experience!read more

Since my first post my thoughts have changed here. It's unfortunate. My doctor and PA were great, but the office staff... is horrible. They never call you back when they say they will, they misinform you, they cause you too much stress wondering what's going on, they don't keep you posted. They never answer the phone. At this point I've left four messages in the last week, and I have sent three messages. Twice from their portal and one direct email. No response. My appointment is on Monday morning at 8:30am, no confirmation on my insurance and what's going on. What the heck is going on, this is ridiculous!I've given up... the stress her office staff has put me through is just not worth it. You can do so much better, please clean house, either change out your office staff, or find a way for them to be more efficient please. You have to do something. This is not how you want to run your practice. It leaves a very bad impression on your more

I love going to this office. The staff is friendly and helpful. The doctor is great. I am getting the best... neurological tests and treatment I have ever had. The only reason I did not give them a 5 star rating is because it is impossible to reach a live person at the office to reschedule appointments. Every time I have tried to get through to the office it says all people are busy and I am sent to a voicemail. If they could get their phone answering fixed, I would give them a strong 5 more

Let me start by saying that I have been coming here for years. Due to my autoimmune disease, I am in this office... once every three weeks for multiple hours at a time. The office is very clean and the staff very friendly. My only complaint would be there communication via phone. They aren't the best at responding if you leave a voicemail and expect a call back. I understand that this is prob just due to the sheer number of alls they receive daily. What I can say I like the best about the office are the people. Bobby who handles my infusions is great. I never have any issues with her setting up my infusions. She is very quick to reply to messages sent via text and if she were to leave then my whole opinion of the office may change. I also enjoy people like Matt, Lauren, and Jodi. I appreciate all that they do for me and without this team I'm not sure I would be as happy as I am to visit the office as frequently as I have to. Please ensure that these folks are recognized as they are what makes my visit to this office so tolerable :).read more
