How to read nerve conduction test results

Some of them include: Along with the NCV, an EMG or Electromyography test is often advised by the doctors. The combined results give a better nerve conduction test results interpretation and thereby diagnose the location, presence and the degree of the damage caused to the peripheral nerves and muscles due to the disease.

What is a nerve conduction test?

Some of them include: Along with the NCV, an EMG or Electromyography test is often advised by the doctors. The combined results give a better nerve conduction test results interpretation and thereby diagnose the location, presence and the degree of the damage caused to the peripheral nerves and muscles due to the disease.

What is the NCV test?

Also referred as the NCV (Nerve Conduction Velocity) test or examination is used for the understanding and determining of the nerve damage. The test examines the pace of the electrical signal movement through the peripheral nerves of the human body.

What does an EMG test tell you?

Normal muscles turn on when necessary and turn off when they don’t need to act. An EMG test will record electrical activity when the muscle turns on. If an EMG shows constant muscle activity, it may indicate a problem, such as muscle spasticity. 2. Timing: Is the muscle firing at the right time? An EMG also measures when a muscle is active.

What is the normal range for nerve conduction velocity?

A nerve conduction velocity between 50 and 60 meters per second is generally considered in the normal range. However, any result has to be examined along with other information. Your doctor will compare the results of your test against a standard, or norm, of conduction velocities.

What to expect during a nerve conduction study?

A nerve conduction study involves applying small electrodes on your skin near a nerve and then recording how strong the electrical activity is. If the signal is slow, your nerve may be damaged. You may experience a mild tingling feeling during this test.

What does a nerve conduction test entail?

A nerve conduction velocity test (NCV) 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.

What is the difference between EMG and NCV?

EMG tests the health of the muscles and related nerves whereas NCV looks for problems only with the nerves. Electromyography is the technical name of the EMG test. In healthy people, electrical impulses control the actions of muscles. NCV, on the other hand, stands for nerve conduction velocity.

What diseases can be detected by an EMG test?

10 Conditions Diagnosed With an EMG

  • Amyotrophic Lateral Sclerosis. Amyotrophic lateral sclerosis-ALS, or Lou Gehrig’s disease-is a progressive neuromuscular disease.
  • Carpal Tunnel Syndrome. Carpal tunnel syndrome affects the median nerve that runs through the wrist.
  • Charcot-Marie-Tooth Disease.
  • Lambert-Eaton Syndrome.
  • Muscular Dystrophy.
  • Myasthenia Gravis.
  • Peripheral Neuropathy.
  • Polymyositis.
