Answer

Electromyography/nerve conduction features include:

  • Symmetric features

  • Sensory findings predominant over motor abnormalities

  • Greater involvement of lower extremities than upper extremities

  • Distal axonal degeneration

  • Significantly reduced sensory and motor amplitudes

  • Normal to mildly reduced sensory and motor conduction velocities

  • Normal to mildly increased sensory and motor distal latencies
