Electromyography and Nerve Conduction Velocity Studies (EMG/NCV)

Electromyography and nerve conduction velocity studies (EMG/NCV) are tests used to detect neuromuscular disorders (nerve and muscle problems).

  • EMG measures the electrical activity of muscles through needle electrodes that are gently inserted into the muscle.
  • NCV measures the speed and intensity of the electrical signals traveling along the nerves and the time it takes a muscle to respond to the signals. The test is often used to detect the cause of problems such as muscle weakness, numbness, spasms, paralysis or pain. During NCS testing, you will feel a tingling sensation.
