A. Perretti et al., PUDENDAL NERVE SOMATOSENSORY-EVOKED POTENTIALS IN PEDIATRICS - MATURATION ASPECTS, Electroencephalography and clinical neurophysiology. Evoked potentials, 104(5), 1997, pp. 383-388
Pudendal nerve somatosensory evoked potentials (PN-SSEPs) were recorde
d in 21 healthy children (age range: 3.3-13.3 years). The dorsal nerve
of the penis/clitoris was stimulated and SSEPs were recorded at spina
l L1-D12 and at cortical Cz'-Fz. Morphology, latency and amplitude of
the cortical SSEPs were evaluated. A cortical response was obtained in
all but two subjects, Cortical SSEPs were broader and less defined in
shape in the youngest subjects. There was a progressive shortening of
the latency of the P and N components during growth. Spinal responses
were obtained only in 6 cases. Nine subjects also underwent tibial ne
rve stimulation. Pudendal and tibial SSEPs differed in their degree of
maturation. (C) 1997 Elsevier Science Ireland Ltd.
