Abstract:
The needle-recording electrodes deviced by the author and the improved recording method were applied in this article. Firstly, the lumbar spinal evoked potentials (LPs) and cortial somatosensory evoked potentials (CPs)to the stimulation of tiable nerves and segmental (radcular) cutaneous nerves (superficial peroneal and sural nerves )were recorded in 50 normal volunteers. Then similiar thacings were recorded and observed in 48 patients with unilateral L_5 or S_1 root compression. We found that the LP to the segmental cutaneous nerve stimulation was abnormal in 85%, and its CP in 48%. The LP to the tiable nerve stimulation was abnormal in 33%,and its CP only in 8%.
