Electromyography is a diagnostic test that measures the electrical activity within muscle fibers in response to nerve stimulation.
- When a nerve stimulates a muscle, electromyography (EMG) measures the muscle's reaction or electrical activity.
- An evaluation and recording method for the electrical activity generated by skeletal muscles is called electromyography.
- A record known as an electromyogram is created during EMG using a device called an electromyograph.
- When a nerve stimulates a muscle, electromyography (EMG) measures the muscle's reaction or electrical activity.
- The test is used to identify aberrant neuromuscular function. One or more tiny needles, commonly known as electrodes, are introduced through the skin and into the muscle during the test.
- Examinations that gauge the electrical activity of muscles and nerves include nerve conduction investigations and electromyography (EMG).
