Electromyography (EMG) and Nerve Conduction Studies: MedlinePlus Lab Test Information

What are electromyography (EMG) and nerve conduction reports?

Electromyography (EMG) and nerve conduction reports are tests that measure the electrical activity of muscular tissues and nerves. Nerves send out electrical indicators to make your muscular tissues respond in specified approaches. As your muscular tissues respond, they give off these indicators, which can then be calculated.
