- Abstract
- This study was performed to evaluate the usefulness of dermatomal somatosensory evoked potentials(D-SSEP) and segrnental somatosensory evoked potentials(S-SSEP) for the diagnosis of lurnbosacral radiculopathy.
D-SSEP and S-SSEP were recorded from 30 healthy controls and 16 patients with
lumbosacral radiculopathy(LA radiculopathy: 10 cases, L5: 13 cases, SI: 4 cases) who
was diagnosed by clinical findings CT and/or MRI.
D-SSEP were abnormal in 40%, 30.7% and 25% of the patients with IA, L5 and Sl
radiculopathy respectively and S-SSEP were abnormal in 20%, 38% and 50% of the
patients with IA, L5 and Sl radiculopathy respectively.
The proportion of abnormal findings in the' patients with L4, L5 and Sl radiculopathy
was increased to 50%, 46. 1% and 50% respectively by administering both of D-SSEP
and S-SSEP.
In conclusion, D-SSEP and S-SSEP are simple and noninvasive test but insensitive
studies for diagnosis of lumbosacral radiculopathy. The diagnostic sensitivity could be
increased by usmg both of these two studies.
