Changes in Motor Latency During Spinal Decompression: Relationship to Outcomes

University of Saskatchewan25 enrolled

Overview

Is there a relationship between changes in motor evoked potential latency intraoperatively and post-operative changes in walking function in patients undergoing spinal decompression.

Is there a relationship between changes in motor evoked potential latency intraoperatively and post-operative changes in walking function in patients undergoing spinal decompression. Tests will include the pre and post decompression MEP (motor evoked potential) latency and pre and post surgery walking speed and quality of life assessments.
