EMG/NCV

What Benefits Are Gained By These Tests?

  • Detect and evaluate damage to the peripheral nervous system, which includes all the nerves that lead away from the brain and spinal cord and the smaller nerves that branch out from those nerves. Nerve conduction studies are often used to help diagnose nerve disorders, such as carpal tunnel syndrome or Guillain-Barre syndrome.
  • Identify the location of abnormal sensations, such as numbness, tingling, or pain.
