Electromyography (EMG), conducted at Associates in Neurology, is a diagnostic procedure designed to assess the health of the muscles and nerve cells (motor neurons) that control them. Your motor neurons transmit electrical signals that make your muscles contract. The results of an EMG can reveal nerve or muscle dysfunction or issues with nerve-to-muscle signal transmission.
An EMG involves the use of tiny electrodes that translate these signals into graphs, sounds, or numerical values that are then interpreted by a neurologic specialist.
During a needle EMG, an electrode is inserted directly into a muscle, which then records its electrical activity.
One of our physicians at Associates in Neurology may order an EMG if you are exhibiting signs that indicate a nerve or muscle disorder. Symptoms include:
- Certain types of pain in arms or legs
- Muscle weakness, pain, or cramping
