The Use of Pulsed Radiofrequency for Sciatic Peripheral Neuropathy in Diabetic Patients in Setting of Pain and Paresthesia

Background: Pulsed radiofrequency is an interventional pain management technique that has been successful in treating radicular pain brought on by nerve damage, trigeminal neuralgia, and thoracic postherpetic neuralgia.Aim of the study: To examine both the therapeutic benefits and potential risks of pulse radiofrequency in the management of pain and paresthesia in patients with diabetes mellitus.Patients and method: A clinical therapeutic trial study was done in Baghdad, Iraq between April 1 and October 1, 2024. A convenient sample of 80 patients who had diabetic neuropathy were enrolled.  The intervention included pulse radiofrequency for two sessions at three months intervals.Results: The proportion of patients with severe paresthesia significantly decreased after the first session (P-value=0.006). Then, it significantly decreased after the second session compared to the first session (P-value=0.029). There was an improvement in the pain as estimated by the VAS score after the first session and after the second session compared to the first session (P-value= were 0.003 and 0.004, respectively).Conclusion: About 50–70% of the patients had pain reduction with improved mobility and reduced medication dependence. It is recommended to repeat pulsed radiofrequency if pain returns (every 3–6 months if needed).
