Abstract

Objective To evaluate the role of dermatomal somatosensory evoked potential (DSEP)exarnination in the diagnosis of lumbosacral disc herniation(LDH) . Methods Somatosensory evoked potential(SEP) from posterior tibial nerve, L5 and S1 derniatomes was recorded from 39 patients with radiculopathycansed by LDH. Results The SEP from posterior tibial nerve was abnormal in 15 cases (38.5%) and theSEP from L5 and or S1 dermatome was abnormal in 34 (87. 2%) (P0. 0001) . The abnormality of SEP fromL5 dermatome was detected mainly in patients with L4-5 LDH, but the abnormality of SEP from S1 dermatomewas demonstrated mainly in patients with L5 S1 LDH. Conclusion The SEP from L5 and/or S1 dermatomewas a sensitive method for the diagnosis of the level of the disc herniation.
