We use different forms of diagnostic testing to understand a patient’s pain. Electromyography (EMG) testing is one of those diagnostic tools that helps us understand how well nerve signals are ... What is an EMG (electromyography)?

Understanding the Context

Electromyography (EMG) is a diagnostic test that evaluates the health and function of your skeletal muscles and the nerves that control them. It’s one form of electrodiagnostic testing. Electromyography (EMG) is a form of electrodiagnostic testing that is used to study nerve and muscle function. It is commonly performed by a physiatrist or neurologist with special training for this procedure.

Key Insights

Sterling Journal-Advocate: Nerve conduction velocity testing (NCV) – a very useful diagnostic test This week we are going to discuss not an injury but a specific test that is performed to diagnose an injury. That test? The nerve conduction velocity test or NCV/EMG. The nerve conduction velocity ... Electromyography (EMG) is a diagnostic procedure to assess the health of muscles and the nerve cells that control them (motor neurons).

Final Thoughts

EMG results can reveal nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle signal transmission. That’s exactly what is an EMG test used to diagnose: it helps reveal whether the problem starts in your nerves, your muscles, the nerve root near your spine, or the tiny space where nerve meets muscle. In plain English, it shows where the signal breaks down so treatment can actually work. An EMG test looks at the electrical signals your muscles make when they are at rest and when used. A healthy muscle should not give off any electrical signals when you aren't moving it.
