NCV Test in Delhi

NCV test can identify nerve damage. during the test, your nerve is stimulated, usually with electrode patches attached to your skin.

Nerve conduction studies help measure the speed at which nerves send messages to the brain. This is done by placing electrodes on your skin. Your consultant then uses electrical activity to record how fast impulse moves along a nerve.

During the test, your nerve is stimulated, usually with electrode patches attached to your skin. Two electrodes are placed on the skin over your nerve. One electrode stimulates your nerve with a very mild electrical impulse. The other electrode records it. The resulting electrical activity is recorded by another electrode. This is repeated for each nerve being tested.

Nerve conduction studies is recommend for following diseases:

  • Neuropathy in patients with diabetes mellitus.
  • Connective tissue diseases.
  • Injury to the nerves.
  • Carpal tunnel syndrome
  • Cervical/lumbar disc prolapse
  • Intake of drugs, which may affect the nerves. (drugs taken for treatment of tuberculosis/ cancer)
  • Guillain Barre Syndrome
  • Hereditary Neuropathy
  • Myasthenia

Symptoms of nerve involvement:

  • Tingling, numbness of hands/feet
  • Burning sensation / pain in the hands and feet.
  • Decreased sensation in arms/legs.
  • Weakness /thinning of arms and legs.

Details of Procedure:

  • Test usually takes 20-30minutes.
  • Metal disc plates (electrodes) are placed on the skin over nerves
  • and muscles and mild electrical stimulation is given and the response is recorded.
  • Usually two nerves in upper limbs and two nerves in lower
  • Limbs are tested. It may be necessary to test more nerves depending on the neurological disease.


  • Wear loose clothes, which will allow easy examination.
  • Fasting not required.
  • For children who are uncooperative sedation may be required.
