Abstract

Objective To study the somatosensory evoked potential in stretch injury of spinal cord.Methods The models of spinal cord injury were set up by the way of dragging the spinal cord with object.And the changes of SEP were measured.Results The latency had extended and the amplitude had cut down after the spinal cord injury(P0.05).The changes of latency and amplitude were correlated with the dragging weight(P0.05).The change of latency was more obviousely than that of amplitude.Conclusion The latency is more sensitive to the stretch injury of spinal cord.
