Your nervous system is a complex network of nerves and specialized cells that send messages throughout your body. When something disrupts this network, tests like nerve conduction velocity (NCV) and electromyography (EMG) help doctors pinpoint the problem.
What are NCV and EMG?
NCV (Nerve Conduction Velocity):Measures how fast electrical signals travel along your nerves. It helps detect whether nerves are damaged and how severe that damage might be.
EMG (Electromyography):Assesses the health of your muscles and the nerves controlling them. It looks at the tiny electrical signals your muscles produce when at rest and when contracting.
Doctors often order these tests together to investigate symptoms like:
They can help diagnose conditions such as:
What Happens During the Tests?
NCV: Small patches (electrodes) are placed on your skin. One electrode sends a mild electrical impulse to stimulate a nerve, while others record how fast the signal travels to a different spot.
EMG:A very thin needle electrode is inserted into a muscle to measure its electrical activity. You might feel slight discomfort.
The Importance of Understanding NCV and EMG
These tests give doctors valuable clues about the source of your symptoms. Is the problem rooted in your nerves or your muscles? The results guide treatment decisions, helping you get the right care.
Empowering Yourself with Knowledge
If your doctor recommends NCV or EMG, don't hesitate to ask questions. Understanding how these tests work and what they reveal can ease anxieties and empower you to be an active participant in your health journey.
