Your muscles move when nerve signals from the brain tell them to get to work. Electromyography (EMG), a diagnostic test, measures how well your muscles respond to those signals. Movement is a complex ...

Electromyography (EMG) is a diagnostic test that measures how well the muscles respond to the electrical signals emitted to specialized nerve cells called motor nerves. EMG tests are safe and pose ...

Nerve conduction studies show how well the body’s electrical signals travel down your nerves. During a nerve conduction study test, providers apply small electrical shocks to your nerve and record how ...

The phrenic nerve is the nerve that controls your diaphragm, the dome-shaped muscle that helps you breathe. The diaphragm muscles expand and tighten the lungs to help you draw air into them. The ...

This week we are going to discuss a diagnostic test which is often ordered to differentiate between diseases of the nerve and muscle, as well as the nerve itself and the myelin sheath of the nerve. A ...

A nerve conduction velocity (NCV) test is used to assess nerve damage and dysfunction. Also known as a nerve conduction study, the procedure measures how quickly electrical signals move through your ...

A nerve conduction velocity test measures the speed of electrical impulses passing through the nerves of the body. In this article, learn about how a nerve conduction velocity or NCV test is used, ...
