What is EMG?

Electromyography (EMG) is a diagnostic technique for evaluating and recording electrical activity in skeletal muscles. It is conducted using needles, also referred to as electrodes, that are inserted through the skin and into the muscle. Electrical activity is detected by the electrodes and displayed on an oscilloscope for medical professionals to interpret the activity. It's common for a patient to be asked to contract the muscle where the electrode was inserted. This produces waves on the oscilloscope that provides insights about the ability of the muscles response to nerve stimulation.

A related procedure may also be performed, called a nerve conduction study (NCS), in conjunction with an EMG. NCS measures the speed and amount of conduction of an electrical impulse through the nerve.[Link to NCS page]

EMG is conducted on an outpatient basis at our clinic. With both EMG and NCS procedures, you will be able to return to your usual activities, unless advised otherwise. Every patient's situation is unique; though we will provide you with the right care and advisement.
