Eligible patients had a clinical diagnosis of ZAP and received either st-SCS or PRF following standard clinical practice. Outcomes assessed included pain severity, neuropathic pain characteristics, QoL indicators, medication usage, and adverse events. Follow-up assessments occurred immediately post-treatment and at 1, 3, 6, and 12 months.
