what is emg testing
Electromyography (EMG) Back to Neurological Tests and Procedures 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, one or more small needles (also called electrodes) are inserted through the skin into the muscle.
THE EMG TEST. Your doctor has referred you for an EMG Study. This study is usually performed as a workup for pain, numbness or tingling in an arm or leg. It tests the condition of the nerves from the spine into the extremity to the foot or hand. There are two parts to the test, the nerve conduction study and the needle EMG Study.
