Evaluation of the Relationship Between Pain and Functional Status, Depression, Anxiety and Quality of Life in Patients with Spinal Cord Injury: Neuropathic Pain in Spinal Cord Injury

Background and Objectives: Neuropathic pain is a prevalent and disabling consequence of spinal cord injury (SCI), adversely affecting physical function, psychological health, social engagement, and overall quality of life. Objectives: This study aimed to determine the prevalence of neuropathic pain in patients with spinal cord injury (SCI) and to examine its associations with clinical and demographic factors, quality of life, depression, and anxiety. Materials and Methods: Eighty-four patients with spinal cord injury (SCI) who were admitted to the Department of Physical Medicine and Rehabilitation and followed up at the rehabilitation outpatient clinic of Dicle University Faculty of Medicine (Diyarbakır, Turkey) were included in the study. Neurological status was assessed using the American Spinal Injury Association (ASIA) scale. Functional ambulation was evaluated with the Walking Index for Spinal Cord Injury (WISCI) and the Functional Ambulation Scale (FAS), while independence was measured using the Spinal Cord Independence Measure, version 3 (SCIM-III). Quality of life was assessed with the Short Form-36 (SF-36), and depression and anxiety were evaluated using the Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI), respectively. The severity of neuropathic pain, fatigue, and paresthesia was assessed using the Visual Analog Scale (VAS) and the Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) questionnaire. Results: Neuropathic pain was observed in 41.7% of patients. No significant differences were found in age, sex, or marital status between patients with and without neuropathic pain. Patients with neuropathic pain had significantly higher Beck Anxiety Inventory (BAI) scores and lower scores in several Short Form-36 (SF-36) domains, including vitality, bodily pain, and emotional well-being. Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) scores were positively correlated with Visual Analog Scale (VAS) fatigue and BAI scores, and negatively correlated with SF-36 domains such as vitality, general health, and bodily pain. Conclusions: Neuropathic pain is a common and debilitating complication following spinal cord injury (SCI). It is closely associated with reduced quality of life and heightened psychological distress, particularly anxiety. Early recognition and effective management of neuropathic pain are crucial for optimizing functional recovery and enhancing psychosocial well-being in patients with SCI.
