Electromyography
Informed by recognized medical guidance
Overview
Electromyography, often called EMG, is a test that checks how well your muscles and the nerves that control them are working. It measures the tiny electrical signals your muscles make when they are active and at rest. This helps doctors find problems like nerve damage, muscle disorders, or issues with the connection between nerves and muscles.
Key facts
- EMG is a safe, low-risk test that provides valuable information about nerve and muscle health.
- The test involves placing small needles into muscles and using patches on the skin to record signals.
- Results can help diagnose conditions like carpal tunnel syndrome, neuropathy, or muscular dystrophy.
EMG is a common diagnostic test used worldwide. Millions of people have it each year for symptoms like weakness, tingling, or pain.
People of any age may need an EMG if they have symptoms suggesting a nerve or muscle problem. It is often used for adults with work-related nerve issues, athletes with muscle injuries, and children with developmental or movement concerns.
