If you believe you are suffering from nerve damage that is affecting your ability to live a healthy and productive life, it’s time to get yourself checked out by a medical professional.
At South Carolina’s Health Edge Group in North Charleston, we offer advanced tests that will correctly diagnose nerve damage – and allow our medical team to develop a treatment plan to address your condition.
At Health Edge Group, we offer two advanced nerve tests.
Nerve conduction velocity, also known as NCV, is a test that measures how quickly electrical signals move through your nerves.
HOW NCV IS PERFORMED
During NCV testing, surface electrodes are placed on your skin over nerves located on various parts of your body. These electrode patches generate mild electrical impulses, which in turn stimulate your nerves.
Electrical activity from the nerve is recorded and data is used to determine how fast nerve signals are traveling.
A second advanced nerve test, known as electromyography or EMG, is often performed simultaneously with the NCV test.
These tests allow us to better diagnose your medical problem and find the best course of treatment.
DOES NCV HURT?
No. But you may feel a slight electric shock and some mild discomfort. You will feel no pain after the test is over.
WHAT IS EMG?
During this test, needles will be inserted into a muscle and you will be asked to contract that muscle. This may be a bit uncomfortable, and some patients may have sore muscles where the needles have been placed.
WHY THE TEST IS DONE
This test helps us diagnose any nerve damage or destruction that you may have suffered. It helps to evaluate nerve or muscle diseases. Some of them are:
- Lambert-Eaton Syndrome.
- Myasthenia gravis.
If you have abnormal results, you may be suffering from:
- Damaged nerve cells.
- A conduction block. This means impulse is blocked along nerve pathways.
- A reduction of fatty insulation around the nerve cell.
Nerve damage can result from a variety of conditions. They are:
- Alcoholic neuropathy.
- Diabetic neuropathy.
- Traumatic nerve injury.
- Guillain-Barré syndrome.
- Carpal tunnel syndrome.
- Sciatic nerve dysfunction.
HOW DO I PREPARE FOR AN EMG TEST?
There are no special steps you need to take before the test, except you should not use any lotions or creams on the day your test is scheduled.
Also, your body temperature may impact test results. So if it’s a cold day, you may need to warm up a bit inside prior to the test.
In addition, let us know if you are on blood thinner medication or any anticoagulants.
This test is typically performed on patients who experience abnormal pain, weakness or unusual sensations. This advanced test can distinguish the difference between muscle weakness that results from injury and muscle weakness that is caused by disorders of the nervous system or muscle diseases.
Typically, there is little electrical activity in muscles at rest. While needles that are inserted during testing may cause electrical activity, after muscles again relax, little activity should be found.
As you flex muscles during testing, electrical activity appears and increases. Patterns form that allow us to tell if your muscle is responding correctly.
If you are experiencing muscle weakness, tingling sensations in your limbs or other unusual symptoms, you may be suffering from nerve damage.
