Nerve Testing Q & A

When Might I Need Nerve Testing?

Nerve testing is a valuable diagnostic tool for many patients suffering from chronic pain. Your doctor at Peak Medical may also recommend nerve testing to determine the underlying cause of symptoms such as tingling, numbness, muscle weakness, and muscle pain.

Nerve testing can locate and diagnose a wide range of nerve injuries or disorders such as:

  • Peripheral nerve disorders
  • Motor nerve disorders
  • Disorders affecting nerve roots at the spinal canal
  • Problems affecting communication between nerves and muscles
  • Disorders affecting nerves in the brain or spinal cord


Pain caused by nerve compression or injury can be diagnosed with nerve testing. These tests also show whether a weak muscle reflects a problem with the muscle or the nerves triggering muscle contraction.


How is Nerve Testing Performed?

Nerve testing includes two different tests:

  • Nerve Conduction Velocity (NCV): An NCV test detects nerve damage by measuring the speed of an electrical impulse as it travels through a nerve. Two or more electrode patches are placed at specific intervals on your skin over the nerve being tested. The electrode at one end sends out a mild electrical shock to stimulate the nerve, while the other electrodes detect the impulse as it’s transmitted along the nerve. The time it takes to get from one electrode to the next is used to calculate the speed.
  • Electromyogram: An EMG measures the electrical activity in a targeted muscle while it’s at rest and when it contracts. Your doctor at Peak Medical places small needles into the muscle. The needles are the electrodes that pick up muscle activity. When the needles are in place, you’ll receive instructions on how to slowly tighten the muscle. The needles detect and record the muscle’s activity, providing information that shows whether there’s any abnormal activity within the muscle while at rest and how well the muscle responds to nerve stimulation. During your nerve testing, surface electrodes that send out an electrical impulse may cause a slight twinge or muscle spasm. You may feel slight pain when the needle probe is inserted for an EMG, but discomfort should be minimal and the test should be painless.
