Electrodiagnostic examinations measure electrical activity generated by muscles and nerves. The results help physicians diagnose the cause of various symptoms, including numbness, pain, or weakness.
Patients having an electromyographic (EMG) test may feel only brief and mild discomfort as the physician inserts a tiny needle into various muscles.
