Changes in Transcranial Motor Evoked Potentials during Intramedullary Spinal Cord Tumor Resection Correlate with Postoperative Motor Function

Abstract

These results support the application of distal muscle-recorded TcMEPs to predict the occurrence and severity of postoperative motor deficits during resection of IMSCTs. Attention to such quantitative intraoperative monitoring data may help to minimize postoperative motor deficits by avoiding or correcting excessive spinal cord manipulation and modifying surgical technique during tumor resection.
