Summary
A new electrophysiologic technique, intercostal somatosensory-evoked potentials (SEPs), easily evaluates thoracic nerve issues. This method aids in diagnosing central and peripheral thoracic neural compromise.
Area of Science:
- Neurology
- Electrophysiology
Background:
- Limited electrodiagnostic tools exist for thoracic nerve root and spinal cord lesions.
- Accurate assessment of thoracic neural compromise is clinically significant.
Observation:
- A novel electrophysiologic technique, intercostal somatosensory-evoked potentials (SEPs), was developed.
- Intercostal SEPs were successfully elicited in 30 neurologically normal subjects.
- Stimulation of various intercostal nerves yielded reliable SEP responses.
Findings:
- Intercostal SEPs are easily and painlessly obtained.
- The technique demonstrates specificity for individual spinal levels.
- This method provides a new tool for assessing thoracic neural function.
Implications:
- This SEP method enhances diagnostic capabilities for thoracic neurological conditions.
- It offers a valuable adjunct for clinicians evaluating neural compromise.
- The technique promises improved diagnosis of both central and peripheral thoracic nerve issues.
