Presence of Dural Pulsation in Patients Diagnosed With Lumbar Spinal Stenosis

Condition(s) studied

Study summary

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

Eligibility

Primary outcome measure(s)

• The Numeric Rating Scale (NRS) — At the time of data collection
  The Numeric Rating Scale (NRS) is a unidimensional, self-reported measure of pain intensity that is widely used in both clinical practice and research, including studies involving patients with chronic pain. On this scale, patients rate their current level of pain on an 11-point numeric range from 0 to 10, where 0 represents "no pain" and 10 represents "the worst pain imaginable." Higher scores indicate greater pain intensity.
• Oswestry Disability Index — At the time of data collection
  The Oswestry Disability Index (ODI) is a widely used and validated questionnaire designed to assess the degree of disability and functional impairment in patients with low back pain. It evaluates the impact of pain on various aspects of daily living and physical function through ten sections, each scored from 0 to 5, with higher scores indicating greater disability. The total score is converted into a percentage by dividing the obtained score by the maximum possible score and multiplying by 100, yielding a final score ranging from 0% (no disability) to 100% (maximum disability).
• SHORT FORM-12 — At the time of data collection
  The Short Form-12 (SF-12) is a health-related quality of life assessment tool that summarizes an individual's physical and mental health status through 12 items. It is a shortened version of the SF-36 questionnaire and measures eight health domains: physical functioning, role physical, bodily pain, general health, vitality, social functioning, role emotional, and mental health. The SF-12 produces two composite scores - the Physical Component Summary (PCS) and the Mental Component Summary (MCS) - which are standardized to a mean of 50 and a standard deviation of 10 in the general population. Higher scores indicate better health status and quality of life.
• Walking Distance Capacity — At the time of data collection
