Somatosensory Evoked Potentials to Lower Extremity Stimulation: Clinical Utility in the Pediatric Age Group
This discussion will deal with somatosensory evoked potentials (SEPs) to lower limb stimulation recorded from the scalp and from surface electrodes attached to the skin over the spine of normal adults, infants and children and patients with diseases affecting the spinal cord and cauda equina. Potentials obtained from surface recordings over the spine are larger and more readily recorded in children. Therefore, this noninvasive method has proven useful in studying maturation of the human nervous system and also in evaluating neural function in children with spinal dysraphism and with diffuse diseases of the nervous system. In adults SEPs obtained from surface electrodes over the spine are often small and difficult to record over rostral cord segments which limits the clinical utility of this technique in older age groups. However,in this situation simultaneous spine and scalp SEPs can be recorded and estimates of spinal conduction velocity can be determined.
