10 kHz SCS; painful diabetic polyneuropathy
Painful diabetic polyneuropathy (PDPN) and painful polyneuropathies of other origins are associated with significant personal and societal burdens with treatments limited to symptomatic management. Treatment options include antidepressants, gamma-aminobutyric acid (GABA) analogs, opioids, and topical analgesics, which are intended to alleviate pain and symptoms of neuropathy, but limited data are available on their efficacy. Paresthesia-based low-frequency spinal cord stimulation (LF-SCS) is considered a last-resort treatment modality for PDPN patients. In a large-scale RCT of neuropathic low back and leg pain, high-frequency SCS at 10 kHz (10 kHz SCS) was shown to provide superior pain relief that is not dependent on paresthesia and a higher responder rate than LF SCS. This retrospective case series includes data from six patients with painful peripheral neuropathies, including PDPN, idiopathic polyneuropathy, and chronic inflammatory demyelinating polyneuropathy, who were candidates for 10 kHz SCS in routine commercial practice. All patients reported a reduction in verbal numerical rating scale (VNRS) pain score at last follow-up (2.7 +/- 0.9) compared with baseline (7.0 +/- 0.9). Out of five patients with information available at last follow-up, two were completely off their pain medications and two reduced their dose by over 40%. Similarly, at last follow-up, three out of five patients reported sensory improvement in their lower limbs. In conclusion, 10 kHz SCS treatment resulted in significant pain relief in all the patients, decreased reliance on pain medication, and improved lower limb sensory function in the majority of patients.
