Objective:To compare the short-term and long-term efficacies and safety of short-term spinal cord stimulation (st-SCS) and pulsed radiofrequency (PRF) in treating zoster-associated pain (ZAP).Methods:A total of 208 ZAP patients who received treatment in Department of Pain Management, Provincial Hospital Affiliated to Shandong University from January 2019 to September 2021 were selected. They were divided into st-SCS group ( n=107) and PRF group ( n=101) according to different treatments. After differences of baseline data being balanced by 1∶1 propensity score matching between the two groups, scores of numerical rating scale (NRS), NRS remission rate, drug dosage, Pittsburgh Sleep Quality Index (PSQI) and complications of 86 patients from each 2 groups were compared and analyzed before surgery, 3 and 7 d after surgery, at discharge, and 1, 3, 6, 12 and 24 months after surgery. Results:NRS scores in st-SCS group and PRF group 3 and 7 d after surgery, at discharge, and 1, 3, 6, 12 and 24 months after surgery were significantly lower than those before surgery ( P<0.05). NRS scores in st-SCS group were significantly lower than those in PRF group at discharge and 1, 3, 6 and 12 months after surgery ( P<0.05). NRS remission rate in st-SCS group was significantly higher than that in PRF group at discharge and 1, 3, 6, 12 and 24 months after surgery, and total effective rate in st-SCS group was significantly higher than that in PRF group 1, 3, 6, and 12 months after surgery ( P<0.05). The pregabalin and gabapentin dosages in st-SCS group and PRF group 1, 3, 6, 12, and 24 months after surgery were significantly lower than those before surgery, and the gabapentin dosage in st-SCS group was significantly lower than that in PRF group 3 months after surgery ( P<0.05). PSQI in st-SCS group and PRF group at discharge and 6, 12 and 24 months after surgery was significantly decreased compared with that before surgery, and PSQI in st-SCS group at discharge and 6, 12 and 24 months after surgery was significantly decreased compared with that in PRF group ( P<0.05). No serious complications as spinal epidural hematoma or spinal nerve root and spinal cord injuries occurred in st-SCS group and PRF group. Conclusion:Both st-SCS and PRF can treat ZAP safely and effectively, but st-SCS has more advantages than PRF.
