Low-frequency dorsal root stimulation is effective for various pain etiologies and pain locations.
Background: Dorsal root ganglion stimulation (DRG-S) has emerged as a novel therapeutic approach for managing chronic neuropathic pain.
Aims: This study aims to compare the effectiveness of 4-20 Hz DRG-S through a retrospective analysis of a cohort of 28 patients with various neuropathic pain etiologies and pain locations.
Materials and methods: Patient responses to both stimulation frequencies were examined using the Numeric Rating Scale (NRS) and Patient Global Impression of Change (PGIC) assessments. Factors such as patient preference and satisfaction were also evaluated.
Results: The results indicate that 4 Hz DRG-S is not only as effective as 20 Hz stimulation but may also surpass it. Among the 28 patients, 26 assessed 4 Hz stimulation to be at least as effective as 20 Hz, with the majority (22 out of 26) considering 4 Hz stimulation superior. After trying 4 Hz stimulation, 24 out of 28 patients chose it over 20 Hz, while two patients opted for a combination of both settings. Only two patients reverted to their original 20 Hz stimulation program. A statistically significant pain reduction of 24% was observed when comparing the effects of 4 Hz versus 20 Hz.
Discussion: The study highlights the broader applicability of low-frequency DRG-S, extending its benefits beyond the realm of low back pain. Patients with diverse pain etiologies and locations experienced comparable positive outcomes, suggesting that the advantages of low-frequency stimulation are not confined to specific pain types or locations.
Conclusion: This study emphasizes the potential of 4 Hz DRG-S as a valuable alternative to the standard 20 Hz stimulation. Although the exact mechanisms require further investigation, the observed clinical benefits and patient preferences for low-frequency stimulation suggest its viability across diverse pain indications and locations. Additional research is necessary to substantiate these findings and assess the durability and economic implications of low-frequency DRG-S.
期刊介绍：
Pain Practice, the official journal of the World Institute of Pain, publishes international multidisciplinary articles on pain and analgesia that provide its readership with up-to-date research, evaluation methods, and techniques for pain management. Special sections including the Consultant’s Corner, Images in Pain Practice, Case Studies from Mayo, Tutorials, and the Evidence-Based Medicine combine to give pain researchers, pain clinicians and pain fellows in training a systematic approach to continuing education in pain medicine. Prior to publication, all articles and reviews undergo peer review by at least two experts in the field.
