CROM performs Electrodiagnostic testing, including Electromyograph (EMG) and Nerve Velocity Conduction (NVC) studies. Electrodiagnostic medicine tests nerve transmissions between muscles and nerves, or how well your nerves and muscles “communicate”.
Electrodiagnostic studies generally take approximately 60 minutes. There are no activity restrictions before or after the test, and there are no lasting effects. Electrodiagnostic scans evaluate weakness, numbness, pain, and symptoms such as fatigue, cramps, and abnormal sensations in the muscles.
During an EMG, the physician studies the electrical activity in muscles by inserting a fine needle electrode into selected muscles. Needle insertion may cause mild, temporary discomfort. The needle is not used for injection and no shocks are given. The physician can determine whether the muscle is working normally by viewing the electrical activity displayed on a screen, while listening to audible transmissions.
To perform the Nerve Conduction Study, the physician tapes small metal electrodes onto the skin and applies a brief electric stimulus to one portion of the nerve. Nerve stimulation will cause a tingling sensation. The physician can then evaluate the electrical response of the nerve or muscle and determine if the nerve impulse is conducted normally.
