Answer

Answer

Electromyography and nerve conduction studies may indicate the following:

  • Differentiation from other rapidly progressive neuropathies such as Guillain-Barré syndrome

  • Widespread denervation

  • Prolonged or absent F-waves

  • Low-amplitude or unobtainable tibial or peroneal compound muscle action potentials and sural nerve action potentials
