Study of Dural Pulsation and Its Link to Symptoms and Imaging in Adults with Lumbar Spinal Stenosis

What this Trial Is About

Lumbar spinal stenosis is a condition where the spinal canal narrows due to degenerative changes in the joints, discs, and ligamentum flavum, causing symptoms like neurogenic claudication, leg pain, low back pain, and sometimes urinary or fecal incontinence. This research aims to explore if the presence of spinal dural pulsation, a rhythmic movement of the dura mater seen in imaging, is linked to clinical symptoms and radiological findings in people diagnosed with lumbar spinal stenosis. Participants will be assessed for the presence of dural pulsation using ultrasound while lying face down. The study groups include those positive for dural pulsation and those negative for it. Magnetic Resonance Imaging MRI will also be used to measure spinal canal features such as dural diameter and cross-sectional area at affected levels. The study correlates these findings with clinical symptoms and disability scores. During the study, participants will undergo evaluations including pain rating scales, disability indexes, quality of life questionnaires, and walking capacity tests. MRI scans will assess anatomical features related to stenosis. These assessments occur at the time of data collection to understand the relationship between dural pulsation and patient symptoms. The study excludes individuals with certain conditions like prior lumbar surgery or inflammatory diseases and plans to complete by the end of 2026.
