Dermatomal somatosensory evoked potentials in children with myelomeningocele.
Evoked responses were obtained from electrical stimulation of dermatomes representing individual lumbar and sacral roots. Normal ranges of latency have been established for adults, but have not been extended to children at this time. DSSEPs can be utilized, however, to sequentially follow lumbo-sacral cord function in individual children at risk of progressive myelopathy.
