This test reveals how fast your nerve impulses travel and can help diagnose neuropathy and other kinds of nerve damage.Īfter your EMG, The Rehab Doctors’ team has valuable information they can use in your diagnosis and treatment planning. Your doctor stimulates your nerve using the needle electrode and then measures the response in the other electrodes. During this test, they place additional electrodes (usually, surface electrodes) below the first.

How does an EMG work?ĭuring a needle EMG, also called an intramuscular EMG, your doctor attaches a needle electrode with one or more very slim wires that go into your muscles.

The Rehab Doctors team may also use EMG to diagnose specific nerve issues before rhizotomy. Some of the many conditions that your doctor can potentially diagnose with an EMG include:
In this test, a state-of-the-art machine records your electrical muscle activity. An EMG is a procedure that The Rehab Doctors’ team uses to diagnose nerve and muscle problems.
