Electromyography
Electromyography (EMG) is a procedure that uses an instrument called an electromyograph to convert the electrical activity from skeletal muscles into a visual account or sound. The test diagnoses neuromuscular abnormalities and is used during biofeedback training.
Nerve Conduction Velocity
Nerve conduction velocity (NCV) is a test to see how fast electrical signals move through a nerve. EMG (Electromyography) testing is done by inserting small needles just into the muscle (mild tingle experienced, similar to acupuncture). These tests are often performed at the same time.
