Electromyography, Nerve Conduction and Other Neurophysiological Techniques

  • Michael Swash

The neuromuscular system can conveniently be investigated by electrophysiological methods. These provide quantitative data which can be used both in diagnosis and in measuring the effects of treatment. The scope of these methods includes:
  • electromyography

  • motor and sensory nerve conduction

  • the measurement of the latencies of late responses, particularly F and H wave responses

  • the assessment of repetitively evoked compound muscle action potentials (decrement testing) in disorders of neuromuscular transmission

  • evoked potential tests

  • somatosensory evoked responses

  • brainstem evoked responses

  • blink reflex latencies

  • motor conduction time, using electrical or electromagnetic stimulation of the central nervous system (CNS)
