During EMG, small pins or needles are inserted into muscles to measure electrical activity. The needles are different than needles used for injection of medications. The pins are small and solid, unlike hypodermic needles, and since no medication is injected, you will experience less discomfort than with shots.
• You will be asked to contract your muscles by moving a small amount during the testing.
• With nerve conduction studies, small electrodes will be taped to your skin or placed around your fingers. You will typically experience a mild and brief tingling or shock, which may be a bit unpleasant.
• The person who administers the test will explain the procedure. Often muscle activity is monitored through a speaker during the test, which may make a popping or soft roaring noise. The EMG technician will be looking at an oscilloscope, which looks like a small TV set, during the procedure.
• Testing may take 30-60 minutes.
