Lumbar spinal stenosis is defined as the narrowing of the spinal canal resulting from degenerative changes in the spinal joints, intervertebral discs, and the ligamentum flavum.
Pressure fluctuations within the cerebral and spinal vascular systems lead to the formation of pulsations. The periodic occurrence of these pulsations in the dura mater is referred to as spinal dural pulsation.The vibratory movements of the dura mater have been interpreted as an indicator that the spinal cord is freely mobile within the subarachnoid space and not subjected to any external compression.This study aims to investigate whether the presence of dural pulsation is associated with clinical and radiological parameters in patients diagnosed with lumbar spinal stenosis
