Nerve Conduction Studies (NCS)

A nerve conduction study, also known as NCS, is a diagnostic test which measures how quickly electrical signals move along a nerve pathway. Nerve Conduction Studies (NCS), are generally performed along with EMG test to further evaluate nerve disease. NCS is used to identify any nerve abnormalities including damage, blocks, and damage or loss of fatty insulation (myelin) around the nerve. NCS can also provide information regarding the condition of the nerve fiber.

How a Nerve Conduction Study Works

During a nerve conduction study, adhesive patches containing electrodes are placed on your skin, over nerves and muscles at different locations. Mild electrical impulses are used to stimulate the nerves.

The time it takes for one electrode to travel to another electrode is measured to determine the speed of nerve signals. The measurements are recorded and read by a specialist.

Why Your Doctor Might Order a Nerve Conduction Study

A nerve conduction study is performed for a wide variety of reasons, including if you experience:

  • Muscle weakness
  • Tingling sensations in your muscles
  • Numbness and loss of function
  • Muscle cramps
  • Muscle pain

Medical Conditions Which Can Be Diagnosed With a Nerve Conduction Study

An NCS can be helpful to confirm a diagnosis or to rule out these conditions:

  • Diabetic neuropathy
  • Bell palsy
  • Myopathy
  • Myasthenia gravis
  • Carpal tunnel syndrome
  • Guillain-Barre syndrome

Preparation for a Nerve Conduction Study

Before you have a nerve conduction study, you need to stay at a normal body temperature. If your body temperature is too cold, it can change nerve conduction speed. Don’t apply any lotions, creams, or oils to your body the day of the test.

What To Expect During a Nerve Conduction Study

During a nerve conduction study, the impulses may feel like a mild electric shock. Mild discomfort may be felt during the test, but it resolves immediately after the test.

What To Expect After a Nerve Conduction Study

An EMG may be performed after the nerve conduction study. The EMG can cause mild bruising and soreness at the needle placement site, which resolves after a few days.
