Evaluating the Prevalence of Motion Abnormalities at Treatment Levels and Nontreatment Levels in Lumbar Stenosis and Spondylolisthesis Patients.

This research letter discusses the importance of normative motion data and validated measurement technology in evaluating spinal motion abnormalities in patients with lumbar stenosis and spondylolisthesis. The study utilized a measurement technology called Quantitative Motion Analysis (QMA) to measure intervertebral motion in patients treated with spinal fusion. The results showed a statistically significant difference in motion abnormalities between treatment levels and non-treatment levels. The study suggests that further research is needed to determine the clinical significance of objective measures of spinal motion and to identify which patients will benefit most from spinal fusion treatment.
