High frequency spinal cord stimulation for chronic back and leg pain

Abstract Background High frequency stimulation (HFS) may provide pain relief without the paresthesias typical of traditional low-frequency Spinal cord (SCS). Methods A consecutive single-center series patients was retrospectively reviewed to evaluate safety and efficacy HF10 therapy. In this 24-month study, 62 with variables pathologies (44 back failure surgery syndrome (FBSS), 18 chronic peripheral neuropathic in lower limbs (NeppL) were included be treated HF10. Pain outcomes compared from preoperative baseline at conclusion each study period. Clinical features, complications reviewed. Results completed study. All had a successful trial before definitive implantation spinal stimulator low dorsal level. The mean follow-up period 11 months, ranging 6 24 months. showed no change visual analogue scale (VAS) after permanent implant 2 improved during but aggravated placement. At 1 month, 63% implanted therapy subjects responders 77% 6 months. average baseline, postoperative Visual Analogue Scale 8.1, 3.6 4.2 respectively. When reduction achieved VAS 4.5 points, accounting for 56% reduction. long-term rate 22%. Conclusions This generated preliminary evidence showing current scores absence increase patient satisfaction stimulation.
