Is Radiofrequency Necessary in Myofascial Pain?

Trigger point injections and erector spina planus muscle (ESP) blocks are used to treat back pain related to myofascial pain syndrome. ESP is the deepest back muscle originating from the transverse processes of the vertebrae. Blocks applied to this region are effective for a longer time and in the broader area than those applied to superficial muscles. Recently, pulsed radiofrequency treatments have also been performed in myofascial pain, and successful results have been obtained.

Deep and superficial back muscles, transverse processes of the vertebrae, costume, and pleural movement are identified by ultrasonographic examination. The investigators perform the intervention through the transverse processes. The investigators give 20 ccs of fluid (bupivacaine, steroids, saline). The patients to whom The investigators apply pulsed radiofrequency complete the procedure by giving 20 ccs of fluid after the radiofrequency application on the transverse processes and during the procedure, using 10 cm, 21 gauge radiofrequency needles with an active tip of 10 mm. The radiofrequency wave is applied at 2 Hz, ten milliseconds, and 55 volts for 5+5 for 10 minutes.

The investigators aim to investigate whether there is a difference between these two applications in terms of treatment efficacy. For this reason, the Visual Pain Scale of each patient will be recorded before the procedure, the second week after the procedure, and the first month. The Centrality of Pain Scale will be applied to these patients at the controls. The correlation between the results of this scale, which evaluates the emotional and physical state of the patients, and the post-treatment pain scales will be evaluated.
