Neuropathic Pain and Disability in Patients with Lumbar Spinal Stenosis

Abstract

In this study, we aimed to determine the characteristics of neuropathic pain and clarify the relationships between the clinical signs, symptom characteristics and disability in patients with lumbar spinal stenosis. Materials and Method: Seventy-nine patients diagnosed with clinical and radiological lumbar spinal stenosis were included in the study. Pain severity was assessed using a selfadministered visual analog scale (0-10 cm). Subjective disability was measured using the Oswestry Disability Index and Istanbul Low Back Pain Disability Index. To identify neuropathic pain, the physician-administered Douleur Neuropathique 4 questionnaire was utilized. Results: A total of 79 patients (35 males, 44 females) with a mean age of 56.88±12.13 (range, 35-89) years were included in the study. The average symptom duration was 24.5 months. The Douleur Neuropathique 4 score was ≥4 in 41 patients (51.8%), indicating that they had neuropathic pain. A significant correlation was observed between the Douleur Neuropathique 4 score and age (R=0.350, p=0.002), body mass index (R=0.239, p=0.034), and visual analog scale (R=0.453, p< 0.001). Conclusion: Approximately half of all patients with lumbar spinal stenosis in our cohort had neuropathic pain. Higher age, body mass index and increased pain scores demonstrate important relationships with neuropathic pain.
