A professional who measures electrical activity in peripheral nerves, using electromyograph (EMG) instrument, for use by physician in diagnosing neuromuscular disorders. Responsibilities include:

• Explains procedures to patient to obtain cooperation and relieve anxieties during test.
• Rubs electrode paste on patient's skin to ensure contact of electrodes.
• Attaches surface recording electrodes to extremity in which activity is being measured to detect electrical impulse.
• Attaches electrodes to electrode cables or leads connected to EMG instrument and selects nerve conduction mode on EMG.
• Operates EMG instrument to record electrical activity in peripheral nerves.
• Presses button on manually held surface stimulator electrode to deliver pulse and send electrical charge along peripheral nerve.
• Monitors response on oscilloscope and presses button to record nerve conduction velocity.
• Measures and records time and distance between stimulus and response, manually or using computer, and calculates velocity of electrical impulse in peripheral nerve.
• Removes electrodes from patient upon conclusion of test and cleans electrode paste from skin, using alcohol and cotton.
