See the list below:

  • Electromyography is useful in evaluating radiculopathy caused by spondylosis when the diagnosis of radiculopathy is in question, but it may have only limited value in assessing myelopathy.

  • In myelopathy, somatosensory evoked potential (SSEP) responses are delayed or have a low amplitude. [16]

  • Cortical motor evoked potentials (MEP) may be more sensitive than SSEPs in evaluating spinal cord dysfunction. [17, 18]
