Sometimes, doctors will order this test to determine whether a nerve or group of nerves is functioning properly. EMGĪn electromyelography (EMG) test measures the speed of transmitting electrical impulses along a nerve. They will also allow doctors to see whether a herniated disk is causing compression of the nerve or the spinal cord. MRI scans can show how severe the nerve compression in the neck is. With the use of magnetic resonance imaging (MRI), doctors can see the vertebrae, soft tissues, and nerves in greater detail than with other scan types. Sometimes, doctors order them in the workup of a person with a suspected pinched nerve. CT scanĬomputerized tomography (CT) scans show bone in more detail than an X-ray. It can also demonstrate narrowing of the foramen and disc spaces between the vertebrae.
X-rayĪn X-ray is one type of imaging tests that can aid in the diagnosis of a pinched nerve in the neck.Īn X-ray can show the alignment of the vertebrae in the neck. The Spurling test involves extending the neck, rotating the head to the side where the symptoms occur, and applying gentle downward pressure to the top of the head. There are several tests that doctors can perform to help them diagnose a pinched nerve in the neck. Oftentimes, they will also ask the person to move their arms and neck to see where they are experiencing weakness or pain. Typically, to reach a diagnosis, doctors will ask about symptoms and then examine the neck, shoulders, arms, and hands.
