Brief summary (from the registry)
Neuropathic pain is described as a "pain initiated or caused by a primary lesion or dysfunction in the nervous system". It is thus often a chronic affection, as a difficult-to-treat condition. As such, there is growing proportion of patients with inefficient pain relief. The prevalence of chronic neuropathic pain has been estimated from 6.9 to 10% in the general population and represents a heavy financial burden for the health care systems. Spinal Cord Stimulation (SCS) is a well-established therapy to alleviate severe intractable neuropathic pain (SCS is a reversible treatment option which leads to improve pain relief and quality of life Using conventional SCS, the prerequisite to target any pain relief is to obtain an appropriate coverage of the painful area with induced paresthesia. Despite its effectiveness, conventional SCS has some limitations (Selectivity, Energy consumption …) and in order to address these limitations and challenges, medical devices and neuromodulation industries have developed the Dorsal Root Ganglion (DRG) stimulation. DRG stimulation appears to be a promising technology that can be proposed to patients with chronic neuropathic pain for several reasons: DRG stimulation has shown promising results in pathologies generating focal pain with more selectively than SCS, lead localization appeared to be less discriminative than SCS. Consequently, DRG seems more stable and efficient to relief pain with lower energy consumption than SCS (therapy can be delivered with very low amplitude compared to SCS). Last but not least, Abbott technology has moved forward to Burst stimulation a couple of years ago and validated this new way of delivering electrical stimulation through several major publications. To our knowledge, applying new waveforms to DRG has not been yet validated. This will represent a fantastic opportunity to refine the design of the next generation of Internal Pulse Generators (IPGs). To date, the baseline study comparing DRG stimulation…
