Neuropathic Pain Severity in Lumbar Spinal Stenosis and Its Link to Radiology
Official title: Neuropathic Pain Severity and Its Association With Radiological Findings in Lumbar Spinal Stenosis
Run by Marmara University · NCT07855445 · Data updated 2026-11-12
This study will test how severe neuropathic pain is in adults with lumbar spinal stenosis and see if it relates to MRI findings and other clinical features.

Is this trial a fit for you?
✓Likely a good fit
Adults 18 years and older with clinically and radiologically confirmed lumbar spinal stenosis and pain or neurogenic claudication who can reliably complete questionnaires.
✕Probably not a fit
Patients whose pain is not neuropathic or whose symptoms do not correlate with imaging may derive limited direct benefit from participation.

What this trial studies
This cross-sectional observational study will measure neuropathic pain using the Neuropathic Pain Symptom Inventory in adults with lumbar spinal stenosis. It will also collect data on pain intensity, functional status, walking capacity, and psychological symptoms to explore associations with radiological findings. The aim is to understand how neuropathic pain characteristics relate to imaging and clinical measures at a single time point. No intervention will be applied; participants will complete questionnaires and undergo standard assessments. The study is led by Marmara University at its Pendik Training and Research Hospital in Istanbul.
Why it matters
Potential benefit: If successful, findings could help clinicians better interpret how pain symptoms relate to MRI findings and guide personalized management for patients with lumbar spinal stenosis.
How similar studies have gone: Previous research has shown links between neuropathic pain features and imaging in spinal stenosis, supporting the potential relevance of this approach.

Inclusion Criteria: * Age ≥18 years. * Diagnosis of lumbar spinal stenosis based on clinical evaluation and lumbar magnetic resonance imaging findings. * Presence of low back and/or leg pain or symptoms of neurogenic claudication. * Sufficient cognitive ability to understand and complete the study questionnaires. Exclusion Criteria: * Presence of diabetic neuropathy, polyneuropathy, peripheral nerve entrapment neuropathy, or other causes of neuropathic pain. * Acute symptomatic lumbar disc herniation considered to be the primary cause of radicular symptoms. * Active malignancy or a history of spinal metastasis. * History of major lumbar spine surgery, such as lumbar fusion. * Severe psychiatric disorder or cognitive impairment that prevents reliable completion of the study questionnaires.
