The doctor will ask about your symptoms and health history. An exam will be done. It will focus on looking for signs of nerve problems in your wrists and hands.

These tests may also be done:

  • Nerve conduction study to measure the speed and strength of electrical activity in the median nerve. A small shock is passed through the nerve to find out whether impulses are slowed in the carpal tunnel.
  • Electromyogram (EMG) —to measure and records the electrical activity of a muscle. They give off signals that are not normal when the nerves attached to them are not working the right way.
  • Ultrasound —to take images to look for problems with the median nerve
