Introduction to EMG
Understanding electromyography (EMG) is key for diagnosing neuromuscular issues. It checks the electrical activity of muscles and nerves. This gives clues about nerve and muscle health. EMG helps spot problems that other tests might not catch.
What is EMG?
EMG is a test to check muscle and nerve health. It looks at the electrical signals from muscles. This helps find issues with nerves and muscles, like muscular dystrophy or peripheral neuropathies.
How EMG Works
EMG records the electrical signals from muscles. When we move, our muscles and nerves work together, making electrical signals. A diagnostic electromyographer uses electrodes to catch these signals.
They then analyze the data to see how muscles and nerves are doing. This helps diagnose and treat nerve and muscle problems.
Types of EMG Tests
There are two main EMG tests: needle and surface EMG. Needle EMG uses a thin needle to record electrical activity in muscles. It’s very detailed and great for finding deeper muscle issues.
Surface EMG uses electrodes on the skin’s surface. It’s less painful and looks at bigger muscle groups. A doctor picks the right test based on your symptoms and health history.
| Type of EMG | Method | Use Case |
|---|---|---|
| Needle EMG | Thin needle electrodes inserted into muscle | Detailed muscle response analysis |
| Surface EMG | Electrodes placed on skin surface | Assessing large muscle groups |
