Group A received an initial voltage of 65 V, which was incrementally increased to the maximum tolerable level (&lt;= 100 V). Group B maintained a steady voltage of 65 V throughout the treatment. The optimal puncture site was determined based on the distribution of rash and pain. With the use of a 16-slice spiral computed tomography (CT) scanner, the needle entry point, angle, and depth were calculated and marked. Under CT guidance, the needle was advanced to the upper edge of the intervertebral foramen, after which the PRF treatment instrument was connected. Accurate needle placement was confirmed through sensory and motor tests that induced a tingling sensation in the symptomatic nerve root area. Pain levels, negative emotional states, quality of life, and sleep quality were measured using the Visual Analog Scale (VAS), Brief Pain Inventory (BPI), Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), and Pittsburgh Sleep Quality Index (PSQI), respectively. The primary endpoint was the pain score at 12 weeks after treatment. Additional data collected included medication use, hospitalization costs and duration, and any adverse reactions.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Sixty patients were finally analyzed.

A significant difference in VAS score was also observed on the first day after the 2 treatments (P &lt; 0.05). Pregabalin consumption was lower in Group A at 12 weeks (P &lt; 0.05).

It is currently treated with a combination of medication and surgery. However, some patients do not experience complete pain relief even after surgery and often experience a period of mild pain until a complete cure. Some studies suggest that the development of HZ is markedly associated with antioxidant factors; however, the relationship between preoperative antioxidant factors and the prognosis of HZ remains undetermined.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Objectives: &lt;/strong&gt;Our study aimed to investigate the relationship between preoperative antioxidant factors and the one-year cure rate in patients with HZ.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Study design: &lt;/strong&gt;A retrospective, observational study.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Setting: &lt;/strong&gt;The study was carried out in the Pain Department of the First Hospital Affiliated to Jiaxing College in Jiaxing, People's Republic of China.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;The clinicopathological data of the patients who were admitted with HZ neuralgia at the First Hospital of Jiaxing from October 2021 through October 2022 were retrospectively analyzed, and their pain cure was followed up over the telephone. Furthermore, the optimal cut-off value of the antioxidant factor was assessed via the receiver operating characteristic (ROC) curve, whereas to evaluate the relationship between the antioxidant factor and various clinicopathologic characteristics of the patient, a c2 was performed. The Kaplan-Meier method was utilized to estimate the cure rate at one year. Moreover, the Cox regression model was used to assess the association of antioxidant factors with the prognosis of patients with HZ neuralgia. Lastly, ROC curves were generated to predict the effect of albumin (ALB), uric acid (UA), and combined ALB-UA (Co ALB-UA) on the patient's prognosis.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;A total of 225 patients were included in this study: 138 women and 87 men, with the median age of 62 years.
