Pre-Operational and Post-Operational Motor Stimulated Potential, Electrophysiological Conduction Studies in Patients with Tethered Cord Syndrome, Neurological Examination and Comparison of Lumbosacral MRG Investigations

Key Points

Preoperative motor evoked potentials significantly predict surgical treatment response in tethered cord syndrome.
Change in motor evoked potential values post-surgery indicates the overall effectiveness of treatment for TCS.
Electrophysiologic studies enhance the assessment of patients undergoing surgical intervention for tethered cord syndrome.
Neurological examinations provide critical insights into patient outcomes following surgical procedures for TCS.

Abstract

Tethered Cord Syndrome (TCS) is a progressive neurologic disorder that is often overlooked in adults, especially in the pre-MRI era. However, it is still unknown whether electrophysiologic studies have any value in determining the outcome of surgery or their usefulness in follow-up. In this study, we aimed to describe the potential of preoperative motor evoked potentials (MEPs) to predict the response to surgical treatment and the change in MEP values after surgery in patients diagnosed with TCS.
