Electromyography (EMG) measures muscle response or electrical activity in response to a nerve's stimulation of the muscle. The test is used to help detect neuromuscular abnormalities. During the test, probes are placed on the skin to detect nerve responses and a small needle is used to check the performance of the muscles. A nerve conduction test measures how well and how fast the nerves send electrical signals.
