Study of Transcutaneous Pulsed Radiofrequency to Relieve Pain in Adults with Postherpetic Neuralgia

What this Trial Is About

Postherpetic neuralgia PHN is a chronic pain condition that can persist long after a shingles rash has healed, causing physical, social, and psychological challenges. PHN results from the reactivation of the varicella zoster virus in nerve cells and affects a growing number of patients as they age. This study aims to evaluate the pain-relieving effects of Transcutaneous Pulsed Radiofrequency TCPRF, a non-invasive treatment, in adults with PHN who have not responded well to standard therapies. The study involves applying TCPRF treatment to the painful skin area affected by PHN. This procedure uses adhesive electrodes placed on the skin to deliver radiofrequency pulses without any incisions. The treatment will be given in three sessions spaced one week apart. Each session lasts 8 minutes and uses specific electrical settings to target the affected nerves. TCPRF is part of routine clinical care at the participating hospital and is not combined with any additional invasive interventions for research purposes. Participants will be adults aged 18 and older diagnosed with PHN who agree to join the study. Researchers will monitor pain levels using the Visual Analog Scale before treatment and at 1 and 3 months afterward. They will also assess different aspects of pain using questionnaires, track any side effects, and measure quality of life changes. Standard safety monitoring will be in place during the procedure. The overall study duration for each participant is about six months, including follow-up visits to evaluate pain relief and well-being.
