Dural pulsation in people with lumbar spinal stenosis
Correlation of the Presence of Dural Pulsation With Clinical and Radiological Parameters in Patients Diagnosed With Lumbar Spinal Stenosis
This study will see if the presence of dural pulsation on MRI is linked to symptoms and imaging findings in people with lumbar spinal stenosis.

What this trial studies
This is an observational study enrolling adults with MRI-confirmed lumbar spinal stenosis to record whether dural pulsation is present. Investigators will collect clinical measures (pain, claudication, disability scores) and correlate them with radiological findings on lumbar MRI. Patients meeting inclusion and exclusion criteria (age 18–85, no prior lumbar surgery, BMI <35, etc.) will be analyzed to identify associations between dural pulsation and disease severity. The goal is to clarify whether dural pulsation relates to patient symptoms or objective imaging features.
Who should consider this trial
Good fit: Adults aged 18–85 who have low back and/or leg pain attributed to lumbar spinal stenosis and MRI evidence of stenosis at least at one symptomatic level are ideal candidates.
Not a fit: Patients with prior lumbar surgery, BMI ≥35, non-stenotic causes of back pain (like isolated radiculopathy from disc herniation or facet/sacroiliac/discogenic pain), major psychiatric illness, congenital spinal anomalies, inflammatory rheumatic diseases, pregnancy, or heart failure are unlikely to benefit from this study.
Why it matters
Potential benefit: If a link is found, dural pulsation on MRI could help clinicians better match imaging findings to symptoms and inform management decisions.
How similar studies have performed: Prior intraoperative and imaging observations have reported spinal dural and CSF pulsations, but the relationship between dural pulsation and clinical or radiologic severity in lumbar stenosis is not well established.
