Electrodiagnostic evaluation of radiculopathies and plexopathies using somatosensory evoked potentials.
Segmental sensory stimulation representing cervical and lumbar dermatomes was used to elicit SEPs in 27 patients with radicular symptoms and/or signs and 12 patients with plexopathies. The test was confirmatory and aided in the anatomical localization in 19 (70%) and 9 (75%) of the respective patient groups. It is concluded that this electrophysiological test usefully complements other electrodiagnostic means of evaluating radiculopathies and plexopathies.
