The information can then be interpreted by a specialist, usually a neurologist, as this type of physician specializes in the brain, spinal cord, and nerve disorders. An electromyography records the signals and converts them into information that is displayed on a monitor. Specific nerve cells called motor neurons transmit signals that cause muscles to stretch and contract. In particular, if it is believed that a certain spinal condition is disrupting the signal transmission from nerves within the spinal cord that are responsible for controlling muscles then electromyography will be performed. Electromyography (EMG) is a diagnostic test that is commonly used by physicians who want to evaluate the health of muscle tissue as well as the motor neurons (nerve cells) that regulate muscle activity.
