Primary outcome measure was pain intensity on the Numeric Rating Scale (NRS). Secondary outcome measure was Patient Global Impression of Change Scale (PGIC).Results Short-term pain relief was observed, with the mean NRS pain score decreasing from 7.7 \u00b1 1.8 at baseline to 2.8 \u00b1 1.2 at one month and to 3.1 \u00b1 1.9 at six months post-procedure (p &lt; 0.001). Long-term pain relief was sustained at twelve and eighteen months post-procedure, with NRS pain remaining at 3.4 \u00b1 2.1 and 4.0 \u00b1 2.7, respectively.Conclusion Radiofrequency denervation of the SIJ can significantly reduce pain in selected patients with sacroiliac syndrome.<\/jats:p>","DOI":"10.1590\/0004-282x20150049","type":"journal-article","created":{"date-parts":[[2015,6,10]],"date-time":"2015-06-10T19:05:38Z","timestamp":1433963138000},"page":"476-479","source":"Crossref","is-referenced-by-count":14,"title":["Long-term
