ABSTRACT: Somatosensory EPs are used to test (1) the peripheral nervous system and (2) the large-fiber tracts in the central nervous system. Clinical utility of SEP stems from the close relationship between the EP waveforms and specific anatomic structures. SEPs are commonly used in cases where multiple sclerosis and other demyelinating diseases are suspected. SEPs also have useful clinical information to yield in infants when neurological abnormalities are suspected, in intraoperative monitoring, and when coma or brain death is present. In the chiropractic setting, short latency somatosensory-evoked potentials yield important clinical information in peripheral nerve lesions, plexopathies, radiculopathies, thoracic outlet syndrome, and spinal cord trauma. Many of these conditions are commonly encountered in the chiropractic setting, and SEPs offer a painless, noninvasive means to demonstrate an abnormal sensory system, uncover functional pathologies is the sensory system, locate the site of an anatomic lesion, and monitor objective changes in a patient’s status throughout treatment.
