What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT07696286). This is a study registration, not published results. Lead sponsor: Marmara University. Recruitment status: COMPLETED. Study type: OBSERVATIONAL. Enrollment: 44 participants (ACTUAL). Conditions: Chronic Pain. Interventions: OTHER: Psychometric Questionnaires and Retrospective Data Collection. Primary outcome measures: Toronto Alexithymia Scale (TAS-20) Score , At study enrollment (single cross-sectional assessment). Brief summary: The purpose of this study is to investigate the relationship between alexithymia levels and clinical parameters, including pain intensity and quality of life, in chronic pain patients treated with spinal cord stimulation (SCS). Chronic neuropathic pain can lead to psychological distress and decreased quality of life. While SCS is an effective neuromodulation therapy for managing refractory pain, patient outcomes vary significantly, suggesting that biomedically similar patients experience different levels of relief due to psychosocial factors. Alexithymia, characterized by difficulties in identifying and describing emotions, may significantly influence the individual pain experience and treatment outcomes. In this cross-sectional observational study, patients who underwent SCS implantation for clinical indications will be evaluated. Clinical data regarding pain history will be collected retrospectively from patient files, while psychosocial profiles will be assessed at a single time point using validated psychometric questionnaires. The study aims to contribute to a better understanding of psychosocial variables in neuromodulation outcomes, potentially aiding in improved patient selection and expectation management.
