Electromyogram

Electromyogram (EMG):  This test determines if a patient has nerve damage at or away from the spinal cord.  Depending on the area of interest, the Doctor will order an EMG of the arms or legs.  There is two parts to an EMG, the Nerve Conduction Velocity (NCV), which determines the speed and function of the nerve, and the Electromyogram(EMG), which determines if the muscles as they interact with the nerve are functioning correctly and for dysfunction of the preganglionic area of the spine.
They are both characterized under the name EMG.  The patient is stimulated with a small voltage of electricity which feels like a tingling sensation in various nerves requested by Dr. Emery.  This part is done by the Technologist.  Then Dr. Emery performs the EMG part which consists of him taking a small needle electrode and placing it in several muscles to determine their function.  

Repetitive Nerve Stimulation Testing(RNS):  This test is done on patients with possible neuromuscular transmission disorders, the most common being Myasthenia Gravis. Symptoms include proximal muscle weakness.  The patient is sat in a chair, and a small stimulus of electricity which feels like a tingling is administered to a nerve repetitively.  Then the patient is requested to exercise the area being tested for about 15-20 seconds, and the test is repeated in about 1.5 minutes post- exercise, and again at about 4 minutes post-exercise.
