Electromyography (EMG) and nerve conduction studies are assessments that evaluate the electrical exercise of muscular tissues and nerves. Nerves send out out electrical signals to make your muscular tissues react in particular approaches. As your muscular tissues react, they give off these signals, which can then be measured.
