ABSTRACT
OBJECTIVE@#To evaluate the diagnostic value of somatosensory evoked potential(SEP) in lumbosacral disc herniation(LDH).@*METHODS@#Posterior tibial nerve somatosensory evoked potential(PTNSEP) and dermatomal somatosensory evoked potential (DSEP) were recorded from 60 patients with radiculopathy caused by LDH and 30 healthy subjects.@*RESULTS@#DSEP was abnormal in 56 cases (93.3%) and PTNSEP was abnormal in 26 cases (43.3%). The significant difference was observed (P<0.001). The abnormality of DSEP from L4 dermatome was detected mainly in patients with L3-4 LDH, the abnormality of DSEP from L5 dermatome was detected mainly in patients with L4-5 LDH, the abnormality of DSEP from L5S1 dermatome was detected mainly in patients with S1 LDH. DSEP can reflect the compressed extent of nerve root.@*CONCLUSIONS@#There was a good correlation of DSEP with lumbosacral nerve root injury,which supplement the information that can not be provided by imaging examingation. DSEP is a sensitive electrophysic method that not only is used to evaluate single nerve root function, but also is helpful in the location of the lesion.
