-Electrodiagnostic procedures include electromyography ([[EMG]]), nerve conduction studies, and evoked potential (EP) studies. EMG assesses the electrical activity in a nerve and can detect if muscle weakness results from injury or a problem with the nerves that control the muscles. Very fine needles are inserted in muscles to measure electrical activity transmitted from the brain or spinal cord to a particular area of the body. With nerve conduction studies the doctor uses two sets of electrodes (similar to those used during an [[electrocardiogram]]) that are placed on the skin over the muscles. The first set gives the patient a mild shock to stimulate the nerve that runs to a particular muscle. The second set of electrodes is used to make a recording of the nerve’s electrical signals, and from this information the doctor can determine if there is nerve damage. EP tests also involve two sets of electrodes — one set to stimulate a sensory nerve and the other set on the scalp to record the speed of nerve signal transmissions to the brain.
