Comparative StudyPercutaneous sciatic somatosensory evoked potential. A comparison to the transcutaneous response.
Cerebral and spinal evoked potentials were recorded in response to percutaneous stimulation of the sciatic nerve at the inferior gluteal crease. To justify the invasiveness of the procedure, a comparison was made to transcutaneous stimulation of the inferior gluteal nerve at the same level.
