Using Electrodiagnostics to Diagnose Pain Symptoms

Electrodiagnostic tests reveal how well your nerves and muscles are working and determine the existence, type and extent of any damage. Identifying the exact source of pain is an important step toward restoring your health.

Nerves and muscles create electrical signals that deliver messages to and from your brain. Any damage to nerves and muscles can slow or stop the travel of these electrical signals. If you have pain, weakness or numbness in your back, neck or limbs, measuring the electrical activity in your nerves and muscles can help your doctor make a proper diagnosis.

Electrodiagnostic testing often is divided into two parts: Nerve conduction velocity (NCV or NCS) and Electromyography (EMG). Both of these are typically conducted during the same session.
