Erector Spinae Plane Block Versus Transcutaneous Radiofrequency in Postherpetic Neuralgia

NCT07400640 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 50

No results posted yet for this study

Summary

This observational study aims to compare the effectiveness of ultrasound-guided erector spinae plane (ESP) block and transcutaneous radiofrequency (RF) treatment in patients with postherpetic neuralgia. Pain intensity and neuropathic pain characteristics will be evaluated using the Visual Analog Scale (VAS) and the Self-Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS) score.

Conditions

  • Postherpetic Neuralgia
  • Neuropathic Pain
  • Herpes Zoster

Interventions

PROCEDURE

Erector Spinae Plane Block

1. Ultrasound-guided erector spinae plane block performed under sterile conditions as part of routine clinical care. After skin antisepsis, a 22-G spinal needle was advanced to the erector spinae plane at the level corresponding to the affected dermatome, and a total volume of 10 mL consisting of dexamethasone, bupivacaine, and normal saline was injected. Patients were observed post-procedure according to standard clinical practice. 2. Transcutaneous radiofrequency treatment applied adjacent to the affected dermatome as part of routine clinical care. Adhesive surface electrodes were placed over the painful area, and pulsed electrical stimulation was delivered by the device for 10 minutes per session. The procedure was performed once weekly for two sessions, without any modification for research purposes.
