Electromyography, or getting an Electromyogram (EMG)

Electromyography tests the electrical activity of the muscles and nerves of the pelvic floor. If a urinary problem may be related to nerve or muscle damage or abnormal movement of the pelvic floor muscles, EMG is used. Small sticky sensors are placed near the urethra or rectum to record muscle and nerve activity. This test measures the strength and activity of muscles and nerves in and around the bladder and sphincters.
