Diagnostic Testing

Electrodiagnostic Examinations

The body uses electrical signals to communicate. Signals can be sent to and from the brain using the body’s muscles and nerves. When injury and/or disease occur in the body, these signals can be affected. These signal disruptions can lead to symptoms of muscle weakness, numbness, tingling, pain, etc. With electrodiagnostic testing, the provider can determine the degree of damage or injury done to the nerves and find out more information regarding the diseases/injuries involving the nerves and muscles. There are primarily two tests that can be performed by either a Neurologist (who studies nerves) and/or a Physiatrist (who studies rehabilitation medicine): An EMG (electromyography) or NCS (nerve conduction study). The EMG looks at the electrical activity of your muscles, while the NCS looks at nerve function.
