Overview
This observational study aims to compare the effectiveness of ultrasound-guided erector spinae plane (ESP) block and transcutaneous radiofrequency (RF) treatment in patients with postherpetic neuralgia. Pain intensity and neuropathic pain characteristics will be evaluated using the Visual Analog Scale (VAS) and the Self-Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS) score.
Description
Postherpetic neuralgia is a challenging neuropathic pain condition that significantly affects quality of life. In routine clinical practice, patients are treated with either ultrasound-guided erector spinae plane block or transcutaneous radiofrequency therapy based on clinician preference and experience.
This observational study includes patients who have already completed one of these treatments as part of standard care in the Algology Clinic. No randomization or modification of treatment plans was performed for research purposes. Patients will be divided into two cohorts according to the treatment they received. Treatment outcomes will be retrospectively evaluated and compared using VAS and S-LANSS scores before treatment, immediately after treatment, and at 1-month follow-up.
