Summary

This study looked at 40 adults with lumbar spinal stenosis (a narrowing in the spine that causes pain and trouble walking) who were scheduled for surgery. Researchers measured how fast they could walk before and after the operation using a 6-minute walk test. The goal was to see if surgery leads to measurable improvements in movement, not just what patients report.
