Introduction

chronic neuropathic pain
Over the past years, dorsal root ganglion stimulation (DRG-S) has become a key instrument in neuromodulation for chronic neuropathic pain. The role of stimulation parameters, especially of stimulation frequency, is less well understood compared to classic spinal cord stimulation (SCS), likely due to the new target structure and the relative newness of the method. We published a first randomized double-blind clinical trial assessing the effect of different stimulation frequencies in DRG-S and demonstrated the superiority of stimulation with 20 Hz over frequencies of 40 Hz, 60 Hz, and 80 Hz [
